Automatic Projector Positioning

The shelf has a memory function similar to a car seat. Once connected and set correctly, it can automatically extend and retract when the projector turns on or off.

Video guide: Watch Here

If the position is set successfully, the shelf should extend to the saved position when you restart the projector.

  • Connect the signal wire from the shelf to the projector USB port.
  • Turn on the projector.
  • When setting the position, press and hold the Retract + Extend buttons until the indicator light flashes 3 times.
  • Make sure the projector is fully shut down and not in standby or sleep mode.

What if I do not have enough ports on my projector?

You may use a bus-powered USB hub.

It allows the projector to slide forward and backward for easier positioning and better cabinet integration.

Are there any color options available?

  • ST550: Silver / Navy
  • ST620: Silver / Navy
What are the differences between ST350, ST550, and ST620?

The main difference is the tray surface size:

Which model should I choose for my projector?

Please measure the projector feet position and compare it with the tray surface dimension.

If the projector feet are slightly outside the tray, another solution is to let the support feet hang outside while the projector body rests securely on the sliding tray.

Can the stand be adjusted for different heights?

No. The UST Projector Smart Stand only supports horizontal movement and positioning.

Does the UST Projector Smart Stand include any accessories?

Two magnets are used to secure the projector feet.

Due to logistics restrictions, magnets may be removed in some shipments.

Frequently Asked Questions

Everything you may want to know before choosing a SCREENPRO® projection screen.

The ideal screen material depends on your projector type, room lighting, and installation environment.

  • UST projector → UST ALR screen material
  • RGB triple laser projector → 3C or 3W anti-speckle material
  • Standard throw projector → white screen or long throw ALR material
  • Dedicated theater → acoustic transparent screen material

If you are unsure, SCREENPRO can recommend a suitable projection screen solution based on your projector model and room layout.

A standard white screen is best for dark or controlled lighting rooms. An ALR screen is designed to reduce the influence of ambient light and improve perceived contrast in brighter environments.

  • White screen → best for dark rooms
  • ALR screen → better contrast with ambient light
  • UST ALR screen → designed for ultra short throw projectors
  • Long throw ALR screen → designed for standard or long throw projectors

The best screen for contrast depends on your projector type and room lighting. In dark rooms, a high-quality white or acoustic transparent screen can deliver natural contrast. In rooms with ambient light, ALR screen materials help maintain deeper blacks and stronger perceived contrast.

  • UST projector → UST ALR screen
  • Standard throw projector → Long throw ALR screen
  • RGB triple laser projector → 3C or 3W anti-speckle material
  • Dedicated cinema room → White or acoustic transparent screen

For RGB triple laser projectors, SCREENPRO recommends 3C Anti-Speckle or 3W Woven Anti-Speckle materials. These materials are designed to reduce laser speckle while preserving image contrast, color performance and viewing comfort.

Technically yes, but a dedicated UST ALR screen usually provides better image performance. UST projectors project light from a steep angle, so a normal screen may show lower contrast, uneven brightness or visible texture depending on the material.

Screen size should be selected according to viewing distance, room size, projector brightness and installation space.

  • 8–10 ft viewing distance → 100"–120"
  • 10–12 ft viewing distance → 120"–135"
  • 12–15 ft viewing distance → 135"–150"

For commercial, church, education or large venue applications, custom screen size recommendations may be required.

  • 3C → balanced anti-speckle performance for RGB laser projectors
  • 3W → stronger anti-speckle performance with woven acoustic transparency

3C is suitable for many triple laser projection setups, while 3W is recommended when stronger speckle reduction and acoustic transparency are required.

Most SCREENPRO® floor-rising screens are designed as freestanding systems and do not require wall fixation for normal use. For special installations, wall brackets or additional securing methods may be recommended depending on the environment.

Temporary waves or wrinkles may be caused by transportation, temperature changes, humidity, storage conditions or installation tension. Tab-tensioned and fixed frame structures generally provide better long-term flatness than non-tensioned or folding screen systems.

Many SCREENPRO motorized projection screens support RF remote control, 12V trigger, USB trigger, RS232, Tuya Smart, Alexa and Google Assistant integration. Compatibility may vary depending on the motor and control system selected.

Yes. Material samples are available for testing before purchasing a complete screen system. Samples can help you compare brightness, contrast, texture, acoustic transparency and anti-speckle performance in your own environment.

Yes. SCREENPRO supports customized screen sizes depending on the screen type, material, aspect ratio and application requirements. Custom options are commonly used for home cinema, commercial spaces, conference rooms, churches and OEM/ODM projects.

Warranty coverage varies by product category. Motorized systems, projection surfaces and accessories are covered under SCREENPRO warranty policies. Please contact SCREENPRO for specific warranty details based on your product model and installation type.
