Common Projector Placement Mistakes Revealed by AV Experts

Mistake #1: Incorrect Throw Distance Calculations

Throw distance errors represent the most common and consequential projector placement mistake. AV professionals sometimes rely on approximations, outdated specifications, or incorrect formulas when determining projector-to-screen distances, resulting in image sizes that don’t match screen dimensions or client requirements.

The Root Cause

Throw distance miscalculations typically stem from confusion about throw ratio definitions, failure to account for zoom lens ranges, or misunderstanding manufacturer specifications. The fundamental formula Throw Distance = Throw Ratio × Image Width appears simple, but complexity emerges with zoom lenses, lens shift capabilities, and aspect ratio considerations.

Manual calculations introduce rounding errors and unit conversion mistakes—particularly when mixing metric and imperial measurements. AV designers working under time pressure may skip verification steps or rely on rough estimates that prove inadequate during physical installation.

Real-World Consequences

Incorrect throw distances force installers to reposition mounting hardware, adjust ceiling infrastructure, or in worst cases, specify different projector models with appropriate throw characteristics. Corporate clients lose conference room access during extended installation periods, while educational institutions face disrupted classroom schedules.

Image quality suffers when projectors operate at extreme zoom positions where optical performance degrades. Edge sharpness, brightness uniformity, and color accuracy all diminish when zoom lenses work outside optimal ranges.

The Professional Solution

Modern projector throw calculators eliminate these errors through automated calculations using verified manufacturer specifications. A projector throw distance calculator accounts for zoom ranges, lens options, and screen formats simultaneously, providing installation teams with precise mounting positions.

XTEN-AV’s calculation engine delivers ±1% placement accuracy by incorporating industry-standard formulas with real equipment specifications. The platform’s multi-brand compatibility enables AV integrators to compare throw characteristics across different manufacturers without switching between vendor-specific tools.

Mistake #2: Ignoring Lens Shift Capabilities and Limitations

Lens shift misunderstandings cause AV professionals to position projectors incorrectly relative to screen centers, forcing reliance on keystone correction that compromises image quality. Lens shift enables optical image repositioning without geometric distortion, but many designers either overlook this capability or misunderstand its operational limits.

Understanding Lens Shift vs. Keystone Correction

Optical lens shift maintains native resolution and rectangular geometry by physically moving lens elements to reposition the projected image. Keystone correction digitally manipulates the image, reducing effective resolution and introducing brightness variations that degrade viewing experience.

Vertical lens shift typically offers ±50-100% image height adjustment, while horizontal lens shift provides ±10-25% image width adjustment. These capabilities vary significantly between projector models, and installation plans must account for specific equipment specifications.

Common Planning Errors

AV designers frequently position projectors beyond lens shift ranges, assuming keystone correction will compensate. This approach sacrifices image quality unnecessarily. Conversely, some installations place projectors at screen center when lens shift could enable more aesthetically pleasing off-center mounting that avoids sightline obstructions.

Rear projection applications particularly suffer from lens shift confusion where mirror systems and throw distance constraints complicate geometry planning. For comprehensive technical comparison, examine Lens Shift vs Keystone: Which Preserves Focus Better?, which analyzes optical quality tradeoffs.

Best Practice Recommendations

Professional installation planning should maximize optical lens shift utilization while completely avoiding digital keystone correction whenever possible. Projector calculator tools must incorporate lens shift specifications when recommending mounting positions.

XTEN-AV’s advanced modeling includes lens shift visualization showing permissible mounting positions that maintain optical image quality. The platform highlights when proposed projector locations would require keystone correction, enabling designers to adjust mounting plans before installation begins.

Mistake #3: Overlooking Screen Size and Aspect Ratio Compatibility

Screen sizing errors create mismatched image proportions where projected images either overflow screen boundaries or leave visible unused screen areas. Aspect ratio confusion between 16:9 widescreen, 16:10 presentation format, and 4:3 legacy standards causes frequent planning mistakes.

The Planning Challenge

Modern projection environments may require supporting multiple content formats from different source devices. Corporate presentations often use 16:10 laptops, while video content originates in 16:9 format. Educational spaces may need compatibility with legacy 4:3 materials alongside modern widescreen content.

Projector native resolutions don’t always match desired screen dimensions, and AV designers must calculate appropriate image scaling and positioning parameters. Zoom capabilities provide some flexibility, but installation planning requires precise screen dimension specifications.

Resolution and Scaling Considerations

Native resolution mismatches between source content and projector specifications impact image sharpness and text readability. 1080p projectors displaying 4K content involve downscaling, while 4K projectors showing 1080p sources require upscaling that affects perceived quality.

For residential applications requiring precise calculations, consult How to Calculate Projector Screen Size for Home Theater, which provides detailed methodologies for optimizing home cinema dimensions.

Calculation Best Practices

Projector screen size calculators should account for viewing distance recommendations, screen gain characteristics, and audience geometry when specifying optimal dimensions. SMPTE standards suggest screen heights between 1/6 and 1/3 of viewing distances for comfortable long-duration viewing.

XTEN-AV’s calculation engine automatically suggests appropriate screen sizes based on room dimensions, seating arrangements, and application requirements. The platform warns when aspect ratio mismatches would create letterboxing or pillarboxing that reduces effective screen utilization.

Mistake #4: Inadequate Ambient Light Analysis

Ambient light assessment failures result in washed-out images, poor contrast ratios, and unsatisfactory viewing experiences despite technically correct projector placement. AV professionals sometimes focus exclusively on geometric calculations while neglecting environmental lighting conditions that fundamentally impact projection visibility.

Environmental Light Sources

Natural daylight through windows, overhead lighting, emergency egress lighting, and reflected light from adjacent spaces all contribute to ambient illumination that competes with projected images. Light levels vary throughout the day and across seasons, particularly in spaces with exterior windows.

Modern LED lighting systems with high color temperatures prove especially problematic for projection quality compared to legacy incandescent sources. Smart lighting integration enabling automated dimming during projection sessions improves viewing conditions significantly.

Brightness Requirements

Projector brightness specifications measured in lumens must exceed ambient light levels by substantial margins to maintain acceptable contrast ratios. Industry guidelines recommend minimum 2:1 contrast ratios, though 5:1 or greater delivers superior viewing experiences.

Screen gain characteristics multiply effective brightness but narrow optimal viewing angles. High-gain screens (1.3-2.5) concentrate light toward central seating positions while reducing off-axis brightness. Unity-gain screens (1.0) provide wider viewing angles with lower brightness amplification.

To optimize brightness calculations for specific environments, reference Projector Screen Brightness Calculator: Improve Brightness, Resolution & Viewing Experience, which provides environment-specific recommendations.

Planning Solutions

Comprehensive ambient light analysis should occur during site surveys using light meters at various times reflecting typical usage patterns. Light control strategies including blackout shades, dimmable lighting, and architectural light control should inform projector specification alongside geometric calculations.

XTEN-AV’s environmental modeling incorporates ambient lighting conditions when recommending projector brightness levels and screen specifications. The platform calculates required lumen output based on measured room conditions rather than theoretical minimums.

Mistake #5: Neglecting Projector Cooling and HVAC Considerations

Thermal planning oversights cause premature projector failures, excessive fan noise, and dust accumulation that degrades optical performance. Mounting positions that satisfy geometric requirements may create unacceptable thermal environments or expose projectors to HVAC airflow that disrupts cooling systems.

Thermal Management Requirements

High-brightness projectors generate substantial heat requiring adequate ventilation clearances. Manufacturer specifications define minimum clearance distances around intake vents and exhaust ports, but installation environments may restrict airflow beyond these basic requirements.

Enclosed soffit installations concentrate heat when ventilation proves inadequate. Summer ceiling temperatures in non-conditioned spaces can exceed projector operational limits, causing thermal shutdowns during critical presentations.

HVAC Interaction Problems

Direct HVAC airflow across projector cooling intakes disrupts designed thermal management, forcing fans to work harder and introducing dust and contaminants into optical paths. Ceiling-mounted diffusers positioned near projectors create problematic airflow patterns.

Temperature fluctuations from HVAC cycling cause optical element expansion and contraction affecting focus stability. Condensation risks emerge when cold supply air contacts warm projector surfaces in high-humidity environments.

Best Practice Thermal Planning

Site surveys must document HVAC register locations, airflow patterns, and ambient temperature ranges that affect projector mounting decisions. Thermal analysis should consider maximum summer temperatures and minimum winter conditions in seasonal climate zones.

Installation specifications may require HVAC modifications, supplemental ventilation, or projector enclosures with controlled airflow. Cable management must avoid blocking ventilation paths or creating heat pockets near projector housings.

Mistake #6: Poor Cable Management Planning

Cable routing oversights create installation delays, aesthetic problems, and signal integrity issues that compromise system reliability. AV integrators focusing on projector positioning sometimes defer cable planning until installation day, discovering routing challenges that force mounting adjustments or require expensive architectural modifications.

Common Cable Planning Failures

Inadequate conduit sizing prevents cable pulling or limits future expansion capabilities. Excessive cable lengths create signal degradation for analog video signals and complicate cable management within equipment racks and plenum spaces.

Power cable routing mixed with signal cables without proper separation introduces electromagnetic interference affecting video quality. HDMI cable length limitations around 50 feet without active extension or fiber optics constrain projector placement options in large spaces.

Infrastructure Requirements

Ceiling access limitations in finished spaces require planning cable paths that avoid structural obstacles while meeting building codes. Fire-rated assemblies demand proper plenum-rated cables and firestopping at penetrations that add installation complexity and cost.

Maintenance access to cable connections at projector locations requires planning service loops and connection accessibility for future troubleshooting. Permanent installations benefit from pull boxes and access panels that facilitate maintenance without ceiling removal.

For hands-on implementation guidance, explore DIY Projector Placement Setup Using a Calculator Tool (Beginner to Pro), which covers practical cable routing strategies.

Professional Solutions

Cable planning should occur during preliminary design using building drawings that show structural elements, HVAC ductwork, and existing infrastructure. 3D modeling tools help visualize cable routing and identify conflicts before construction begins.

XTEN-AV’s integrated approach includes cable routing visualization within 3D room models, enabling designers to plan conduit paths and verify access clearances during design development. The platform calculates required cable lengths including service loops for accurate material estimates.

Common Projector Type Selection Mistakes

Ultra-Short Throw Misconceptions

Ultra-short throw (UST) projectors offer compelling advantages for space-constrained environments but introduce unique planning considerations often overlooked by AV professionals unfamiliar with these systems:

UST projectors require extremely precise mounting positions—even small placement errors of 1-2 inches cause significant geometry problems. Wall flatness and screen mounting precision become critical success factors where traditional ceiling-mounted projectors tolerate greater installation tolerances.

Ambient light rejection (ALR) screens prove essential for UST deployments in environments with ambient lighting, but these specialized surfaces cost substantially more than standard projection screens. Budget planning must account for premium screen requirements.

Long Throw Applications

Auditoriums and large venues requiring long throw distances beyond 40-50 feet introduce lens selection complexities not present in typical commercial installations. Zoom lens ranges may prove insufficient, requiring interchangeable lenses or fixed long-throw optics.

Image brightness decreases proportionally with throw distance following inverse square law—doubling projection distance requires quadrupling lumen output to maintain equivalent screen brightness. High-brightness projectors exceeding 10,000 lumens become necessary for large-venue applications.

Projector Calculation Workflows: Step-by-Step Process

Initial Requirements Gathering

Professional projection design begins with comprehensive requirements documentation:

1. Measure room dimensions including length, width, and ceiling height

2. Document viewing distances from screen to furthest seating positions

3. Assess ambient lighting at different times matching typical usage patterns

4. Identify mounting constraints from structural elements, HVAC systems, and architectural features

5. Determine content types and aspect ratio requirements for source materials

Using a Projector Throw Calculator

Projector throw calculators require specific inputs to generate accurate recommendations:

Screen Size Determination: Use a projector screen size calculator to identify optimal viewing dimensions based on audience geometry and viewing distance guidelines. SMPTE standards provide baseline recommendations, but application-specific requirements may justify deviations.

Throw Ratio Selection: Choose projector throw ratios appropriate for available mounting distances. A projector throw ratio calculator helps evaluate whether short throw, standard throw, or long throw models suit the installation environment.

Distance Calculation: Apply the projector throw distance calculator to determine exact projector positioning for desired screen sizes. Account for zoom ranges that provide mounting flexibility within specified distance constraints.

Verification and Optimization

Design validation requires checking calculations against manufacturer specifications and verifying installation feasibility:

• Confirm lens shift ranges accommodate proposed mounting positions

• Verify brightness requirements considering ambient light and screen gain

• Check clearances for ventilation, service access, and cable routing

• Validate power availability at planned projector locations

Frequently Asked Questions About Projector Placement

What is the most important factor in projector placement planning?

Accurate throw distance calculation represents the most critical factor in projector placement planning. Incorrect throw distances cause image size mismatches, focus problems, and may require complete reinstallation. Professional projector calculators eliminate these errors by precisely calculating mounting positions based on verified equipment specifications and room geometry. Secondary considerations including lens shift capabilities, ambient lighting, and thermal management build upon this foundational calculation.

How do I calculate the correct projector throw distance for my installation?

Throw distance calculation uses the formula: Throw Distance = Throw Ratio × Screen Width. First, determine desired screen width based on viewing distances and room dimensions. Then identify your projector’s throw ratio from manufacturer specifications—typically ranging from 0.3:1 for ultra-short throw models to 3.0:1+ for long throw projectors. Multiply these values to find required mounting distance. Professional projector throw calculators automate this process while accounting for zoom ranges, lens shift, and installation tolerances.

Can I use keystone correction instead of proper projector positioning?

Keystone correction should be avoided whenever possible as it digitally manipulates the projected image, reducing effective resolution and introducing brightness variations. Optical lens shift maintains native image quality while repositioning the projection. Proper projector placement utilizing lens shift capabilities delivers superior image quality compared to keystone-corrected installations. Reserve keystone correction only for temporary setups or situations where mounting constraints prevent optimal positioning.

What projector brightness do I need for a room with windows?

Projector brightness requirements depend on ambient light levels and screen size. As a baseline, spaces with ambient light require minimum 2,500-3,500 lumens for screens around 100-120 inches diagonal. Rooms with uncontrolled natural daylight may demand 5,000-10,000 lumens or more. Light control strategies including blackout shades dramatically reduce brightness requirements. Use a projector screen brightness calculator that considers measured ambient light levels, screen gain, and desired viewing quality for accurate recommendations.

How far should a projector be from the screen?

Optimal projector distance varies based on throw ratio and screen size. Standard throw projectors (1.5:1 ratio) require approximately 12-15 feet for a 100-inch screen, while short throw models (0.5:1) need only 4-5 feet. Ultra-short throw projectors can be placed within 6-12 inches from the screen surface. Zoom lenses provide flexibility within specified ranges—for example, a 1.5:1 to 2.0:1 zoom lens allows mounting distances between 12-16 feet for the same screen size. Always verify manufacturer specifications for precise throw distance ranges.

What’s the difference between throw ratio and throw distance?

Throw ratio represents the relationship between projection distance and image width, expressed as a ratio (e.g., 1.5:1). This specification describes projector lens characteristics independent of specific screen sizes. Throw distance measures the actual physical distance from projector lens to screen surface, typically measured in feet or meters. Throw distance equals throw ratio multiplied by screen width. Understanding this distinction helps AV professionals select appropriate projector models for specific installation environments.

Do I need a professional projector calculator tool for residential installations?

While simpler than commercial projects, residential home theater installations still benefit significantly from professional projector calculators. Home cinema optimization requires precise viewing distance calculations, screen sizing, and projector positioning to achieve cinema-quality experiences. DIY enthusiasts using quality calculation tools achieve results comparable to professional installations while avoiding costly placement mistakes that require remounting or equipment changes. XTEN-AV and similar platforms provide both professional features and accessible interfaces suitable for residential applications.

Why Generic Lumen Charts Fail (And Why You Need a Proper Calculator)

The Problem with “Rule-of-Thumb” Approaches

Many AV professionals still use outdated methods:

• “100-inch screen = 3000 lumens” (ignores ambient light)

• “Dark room = 1500 lumens is fine” (ignores screen gain)

• “Brighter is always better” (ignores eye fatigue and hotspotting)

Real-World Variables These Rules Ignore:

• Conference room: 120″ screen, moderate ambient light (30 fc), white matte screen (gain 1.0)

• Basic formula says: 4000 lumens

• Proper calculator accounts for ambient light and recommends: 6500 lumens

The difference? A usable presentation system vs. barely visible content.

Step-by-Step Guide: Using a Projector Screen Brightness Calculator

Step 1: Measure Your Screen Dimensions

Start with accurate screen size measurements:

• Width (measured in feet, inches, or meters)

• Height (maintain aspect ratio: 16:9, 16:10, 4:3)

• Diagonal (optional but helpful for verification)

Pro tip: Always design for the actual viewable area, not frame dimensions.

Step 2: Assess Ambient Light Conditions

Ambient light is the biggest variable affecting brightness requirements.

Measurement Methods:

• Light meter (measures foot-candles or lux)

• Visual assessment (bright office, dimmed conference room, pitch-black theater)

• Time-of-day analysis (natural light variation)

Common Environments:

Step 3: Determine Screen Gain

Screen gain measures how much light a screen reflects compared to a standard matte white surface (gain = 1.0).

Screen Gain Types:

• 0.8-1.0 (matte white): Wide viewing angle, neutral color

• 1.3-1.8 (high-gain): Brighter image, narrower viewing cone

• 2.0-3.0 (ultra-high-gain): Maximum brightness, very narrow angle

Trade-off: Higher gain = brighter center, but hotspotting and reduced off-axis viewing.

Best practice: Use 1.0-1.3 gain for most applications unless dealing with extreme ambient light.

Step 4: Define Application and Image Quality Goals

Different applications have different brightness standards:

AVIXA Brightness Recommendations:

1. Screen width and height

2. Screen gain value

3. Ambient light level (foot-candles or descriptive)

4. Application type (presentation, cinema, etc.)

5. Viewing distance (optional for comfort assessment)

Step 6: Review Calculated Lumens Requirement

The calculator outputs:

✅ Minimum recommended lumens

✅ Optimal lumens range

✅ Brightness uniformity (center vs edges)

✅ Contrast ratio expectations

Example output:

• Screen: 150″ diagonal (16:9), gain 1.0

• Ambient light: 30 fc (conference room)

• Application: Business presentations

• Result: Minimum 7,500 lumens, optimal 9,000-10,000 lumens

Step 7: Select Appropriate Projector

Use the lumen requirement to filter projectors:

• Laser projectors (10,000+ lumens, maintenance-free)

• Lamp-based projectors (cost-effective for lower lumens)

• LED projectors (lower lumens, longer lifespan)

XTEN-AV suggests projector models based on calculated requirements and budget.

1. ANSI Lumens

Definition: Standardized measure of light output from a projector, measured using the ANSI (American National Standards Institute) method.

Typical ranges:

• Home theater: 1,500-3,000 lumens

• Business: 3,000-5,000 lumens

• Large venue: 5,000-30,000+ lumens

2. Foot-Lamberts (ft-L)

Definition: Measure of brightness on the screen surface (luminance).

Formula:

Foot-Lamberts = (Lumens × Screen Gain) ÷ Screen Area (sq ft)

SMPTE standards:

• Cinema: 14-16 ft-L

• Presentation: 15-25 ft-L

3. Lux and Foot-Candles (fc)

Ambient light measurements:

Common Mistakes in Projector Brightness Calculation (And How to Avoid Them)

Mistake 1: Ignoring Ambient Light

Problem: Using a dark-room formula for a lit conference room

Solution: Always measure or estimate ambient light accurately. Use a projector calculator that accounts for lighting conditions.

Impact: Under-specification can lead to 50-70% reduction in perceived image quality.

Mistake 2: Overlooking Screen Gain

Problem: Assuming all screens are gain 1.0

Solution: Confirm actual screen gain with manufacturer specs. High-gain screens can compensate for lower lumens but reduce viewing angles.

Trade-off: A gain 1.8 screen can reduce lumen requirements by 40-50% but creates hotspotting and uneven brightness.

Mistake 3: Using Diagonal Instead of Width/Height

Problem: Inputting diagonal screen size when calculators need width and height

Solution: Convert diagonal to width/height based on aspect ratio:

• 16:9 aspect: Width = 0.872 × Diagonal

• 16:10 aspect: Width = 0.848 × Diagonal

• 4:3 aspect: Width = 0.8 × Diagonal

XTEN-AV accepts both formats and auto-converts.

Mistake 4: Not Accounting for Brightness Degradation

Problem: Specifying exact calculated lumens without overhead

Solution: Add 10-20% buffer for:

• Lamp aging

• Dust accumulation

• Eco mode operation

Mistake 5: Ignoring Content Type

Problem: Using cinema standards for data presentations

Solution: Match brightness to content requirements:

Mistake 6: Overlooking Viewing Distance

Problem: Specifying brightness without considering viewer comfort

Solution: For close viewing (home theaters), lower brightness reduces eye strain. For large venues, higher brightness compensates for distance.

• Maximum: 10,000 lumens (for future-proofing)

4. Document Environmental Assumptions

In your AV proposal, clearly state:

• Assumed ambient light levels

• Screen gain used in calculations

• Viewing conditions (dimmed, lit, etc.)

This protects you if conditions change.

5. Consider Total Cost of Ownership

Higher-lumen projectors often mean:

Balance brightness with operational costs.

6. Coordinate with Lighting Control

Integrate projection systems with:

This allows dynamic brightness optimization.

7. Test Before Final Installation

Whenever possible:

Advanced Brightness Optimization Techniques

1. Dynamic Brightness Management

Modern projectors offer:

• Eco mode (reduces brightness and power)

• Auto brightness adjustment (based on content)

• Scheduled brightness profiles (time-of-day optimization)

Best practice: Design for full brightness but operate in eco mode for extended lamp life.

2. Screen Surface Selection

Screen technology dramatically impacts perceived brightness:

Matte White (Gain 1.0)

• Pros: Wide viewing angle, neutral color

• Cons: Lower effective brightness

• Best for: Dark rooms, home theaters

High-Gain (1.3-1.8)

• Pros: Brighter image, combats ambient light

• Cons: Narrower viewing cone, potential hotspotting

• Best for: Conference rooms, moderate ambient light

ALR (Ambient Light Rejecting)

• Pros: Rejects overhead light, maintains contrast

• Cons: Expensive, specific installation requirements

• Best for: Bright rooms where dimming isn’t possible

Gray Screens (0.8-0.9 gain)

• Pros: Better blacks, improved contrast

• Cons: Requires more lumens

• Best for: Home theater with high-contrast content

3. Lens Shift vs Keystone Correction

Brightness preservation:

Always prefer optical lens shift over digital keystone.

It depends on:

Use a projector brightness calculator for precise recommendations.

3. What is screen gain and why does it matter?

Screen gain measures how much light a screen reflects compared to a standard matte white surface (gain = 1.0).

Impact:

Best practice: Use 1.0-1.3 gain for most applications unless dealing with extreme ambient light.

4. Can I use a home theater projector in a bright room?

Generally no. Home theater projectors (1,500-2,500 lumens) are designed for dark environments.

For bright rooms:

• Use 4,000+ lumen business-class projectors

• Add an ALR screen

• Implement lighting control to dim ambient light

5. How do I calculate lumens for outdoor projection?

Outdoor projection requires significantly higher lumens:

• After dark: 5,000-10,000 lumens for 150-200″ screens

• Twilight: 10,000-20,000+ lumens

• Daylight: Generally not feasible (requires 30,000+ lumens)

Key factors:

• Screen size (larger = more lumens)

• Time of day (darker = fewer lumens needed)

• Reflective surfaces nearby

6. Does projector placement affect brightness?

Yes, indirectly:

• Off-axis placement may require keystone correction, which reduces brightness

• Long throw distances don’t reduce lumens, but require brighter initial output for same screen brightness

• Ceiling bounce and reflections can improve or worsen perceived brightness

Use lens shift whenever possible to maintain full brightness.

7. What’s the difference between ANSI lumens and LED lumens?

• ANSI lumens: Standardized measurement method (accurate, comparable)

• LED lumens: Often inflated marketing numbers (not standardized)

Always specify ANSI lumens in professional AV designs.

8. How often should I recalculate brightness for a project?

Recalculate when:

• Screen size changes

• Ambient lighting conditions are modified

• Room layout changes (windows added, walls painted)

• Projector technology improves (upgrading older systems)

9. Can I use multiple lower-lumen projectors instead of one high-lumen unit?

Yes, for:

• Ultra-wide displays (edge blending)

• 3D mapping and unconventional surfaces

• Redundancy in critical applications

Challenges:

• Color matching

• Brightness uniformity

• Increased complexity

XTEN-AV calculates distributed lumen requirements for multi-projector systems.

10. What’s the impact of 4K resolution on brightness?

4K projectors often have:

Design consideration: May need to increase lumens to maintain the same foot-lambert levels as 1080p systems.
