What Makes Ultra Short Throw Laser Projectors Special?

Ultra short throw (UST) laser projectors are a relatively new category of display technology that has quickly gained popularity among home theater enthusiasts and AV professionals alike. But what exactly sets them apart from standard projectors and TVs?

The key differentiating features of UST laser projectors are:

  1. Ultra short throw distance: As the name implies, UST projectors can cast a large image from an extremely short distance. While long throw projectors need around 6-10 feet of space between the lens and screen to project a 100" image, UST projectors can achieve the same size from just 6-20 inches away. This is made possible by a combination of advanced optics and laser light technology.

  2. Laser light engine: Instead of using a traditional lamp, UST projectors employ a laser light source, either in the form of a single blue laser with a phosphor wheel, a dual laser system, or a triple RGB laser array. Lasers offer numerous advantages over lamps, including:

    • Higher brightness (2500-6000 ANSI lumens) for clear images in any light level
    • Wider color gamut (up to 100% DCI-P3) for richer, more lifelike colors
    • Instant on/off with no warmup or cooldown period
    • Longer lifespan (up to 30,000 hours) for reduced maintenance costs
    • More flexible mounting options in any orientation
  3. Advanced image processing: To maintain image quality and geometry when projecting at such extreme angles, UST laser projectors rely on sophisticated image processing algorithms. These can include:

    • Keystone correction and 4-corner warping to square up the image
    • Depth-based object detection to avoid obstacles in the light path
    • HDR tone mapping for enhanced contrast and detail
    • Motion smoothing and gaming modes for fast-paced content

By combining these technologies into a sleek, compact chassis, ultra short throw laser projectors provide a unique big screen experience suitable for a wide range of environments, from dedicated home theaters to living rooms, bedrooms, and even offices.

UST Laser Projectors vs. TVs and Standard Projectors

To put the advantages of ultra short throw laser projection into perspective, let‘s compare them against the most common home display options: flat panel TVs and conventional projectors.

UST Laser Projectors vs. TVs

Feature UST Laser Projectors TVs
Screen size 80" – 150" 32" – 85" (limited by size/weight)
Depth 10" – 20" from wall 2" – 3" wall mount, 8"+ with stand
Brightness 2000 – 6000 lumens 200 – 2000 nits (highly variant)
Contrast ratio 1,000,000:1 (dynamic laser) 5000:1 – 1,000,000:1 (OLED)
Viewing angle 150°+ (diffuse screen) 120° – 178° (limited off-axis)
Lifespan 20,000 – 30,000 hours 30,000 – 100,000 hours (variant)

Power consumption 250W – 600W 50W – 500W
Price (100" 4K) $2500 – $6000 $5000 – $30,000

As we can see, the primary advantage of UST laser projectors over TVs is the ability to achieve a massive screen size at a fraction of the cost. For example, a 120" 4K UST projector like the Samsung LSP7T costs $6500, while a comparable 120" 4K TV like the TCL 120R648 costs $17,000. That‘s a savings of over $10,000 for the same image size!

UST projectors also offer more flexible placement options since they don‘t require a wall mount or stand. Simply place the projector cabinet on an existing credenza or low table and you‘re ready to watch. The laser light source generates less heat than a TV panel, allowing for a more compact form factor.

However, TVs still have some advantages, particularly in terms of simplicity and light output. A high-end OLED or QLED TV can achieve much higher brightness (measured in nits) than a projector, making them better suited for brightly lit rooms. TVs also require less calibration and maintenance over time.

UST Laser Projectors vs. Standard Long-Throw Projectors

Feature UST Laser Projectors Standard Projectors
Throw distance 0.15 – 0.4:1 (ultra short) 1.0 – 2.0:1 (long)
Placement Console/credenza (front) Ceiling/rear mount
Brightness 2000 – 6000 lumens 1000 – 3000 lumens
Light source Laser (20,000+ hours) Lamp (3000 – 8000 hours)
Color gamut 100% DCI-P3, Rec. 2020 Rec. 709, DCI-P3

Orientation 360° (any) Horizontal +/- 20° tilt
Shadows/glare Virtually none Presenter shadows, lens glare
Price (4K) $2500 – $6000 $1500 – $5000

Compared to traditional long-throw projectors, the main benefit of UST laser models is the massive reduction in throw distance. By placing the projector just inches from the wall, UST setups eliminate the need for long cable runs, ceiling mounts, and complex installations. This makes them ideal for apartments, small rooms, and ad-hoc setups where a conventional projector won‘t fit.

UST laser projectors also tend to be brighter than lamp-based models thanks to the higher light output of lasers. The wider color gamut and longer lifespan of laser light engines further improve image quality and reduce maintenance costs over time.

On the downside, UST projectors are generally more expensive than their long-throw counterparts, especially at the high end. They also require a very flat, uniform projection surface to avoid geometry issues. UST ALR screens can cost $500 – $3000 on top of the projector price, whereas long throw projectors can use a standard white screen or even a bare wall.

These screens use optical coatings and microstructures to absorb off-axis light and boost contrast. The Grandview Dynamique UST ALR screen and Spectra Projection Vantage UST ALR screen are two excellent options.

  2. Adjust the projector placement: Position the projector cabinet perpendicular to the screen, centered horizontally, and level with the bottom edge of the screen frame. Use the projector‘s adjustable feet to fine-tune the alignment. Avoid placing the projector at an angle, as this can introduce geometry issues like trapezoidal distortion.

  3. Fine-tune the image geometry: Use the projector‘s built-in test patterns and adjustment controls to dial in the geometry and alignment. Start by correcting any keystone distortion using the 4-corner warping function. Then, use the focus control to achieve maximum clarity across the entire image. Some UST projectors offer auto-calibration features that use a camera to optimize the geometry.

  4. Calibrate the color and contrast: For the most accurate colors and contrast, calibrate your UST projector using a colorimeter or spectroradiometer and calibration software like CalMAN or ChromaPure. Follow the recommended settings for your specific projector model and screen type. If you‘re not comfortable performing a full calibration, at least adjust the basic picture settings like brightness, contrast, and color temperature to match your room conditions and content type.

  5. Optimize your viewing environment: To get the most from your UST projector, aim for a dark viewing environment with minimal ambient light. Use blackout curtains or shades to block external light sources, and avoid placing lamps or reflective surfaces directly opposite the screen. If you can‘t fully control the room lighting, consider an ALR screen with a higher gain to help reject ambient light.

By following these tips and investing in the right equipment, you can achieve a truly cinematic experience with your UST laser projector that rivals or exceeds the best home theater setups.
