Projector Info

*Not compatible with ultra short throw projectors or edge-blending due to risk of hot spots
*Works best when the minimum throw distance is 1.5 times the width of the image
*The ambient light must never come from the same direction as your projector
*Install the projector so the projected light mirrors the reflected light with equal angles and is aligned at eye level for best results.
See your movies as they are meant to be seen
Experience the most vivid colors and crystal clear audio, on a projector screen that has been designed to transport you to another world. Hear every whisper, see every detail, and be swept away to another time and place, living a different life, even if it’s only for the evening.
In-ceiling Installation for Ultimate Invisible Integration
Integrating your motorized screen into any room has never been so easy. Our all-aluminum casing and unique mounting solution allows you to place your screen flush inside the ceiling without hassle, and with no drywall patching required.  The screen can be mounted using a variety of methods, including steel rods, aircraft cables, or by direct bolt-on method.
Smooth Projection Surface with Pure-Flat Technology
Creased and wrinkled screens are a thing of the past with our Pure-Flat Tensioning System. It involves two tensioning stages: first we’ve added a heavy-duty steel weight bar at the bottom which provides vertical tension of the screen. The second stage uses tabs held under tension by aircraft cable at each side, providing horizontal tension. Together, this ensures a smooth surface, preventing curling and delivering a wave-free screen for years to come.
Control Systems
• Internal Radio Frequency/Infrared receivers with IR, RF remotes included 
• Low voltage 3-way wall switch 
• Standard 5-12 volt trigger to synchronize screen operation with the projector's power cycle
• Programmable Central control
Remotes and Wall Control Panel
The In-Ceiling series comes with wall control panel, 110V/220V outlet plug, as well as two remotes – one IR and one RF remote control. This ensures our screens can be operated under a variety of situations with the upmost ease. Furthermore, the 110V/220V plug means you can get our screens up and running quickly and easily.
Seamless Integration with your Smart Home System
Your home automation system controls everything around your house, so why should your Home Theater be any different. By including a motorized screen into your household you will be able to manage and control everything from your favorite control system. Our motorized units feature a conventional 12V trigger that can be used on other devices as well.
Enjoy the Benefits of Precision Engineering
The screen material is rolled onto a large diameter roller tube, making the screen surface flatter, as there is less curvature in the material when it is rolled up, versus the much smaller roller tubes commonly employed by most other screen manufacturers. It ensures that the screen surface is wrinkle-free and without any distortions to create the ideal surface for the movie to be projected upon.
Easy Access to Motor and Controls
The In-Ceiling screen features an easy to remove screen panel, allowing you to access the screen material and the motor without removing the housing. This means that you will absolutely never have to remove the housing from the ceiling, whether you need to modify/change the motor settings, install a 12V trigger or adjust the drop limits of your screen.
Adjusting Limit Switches
Limit switches are located on the left side of the screen and inside the housing. The limit switches should only be adjusted with the provided adjustment tool.   The limits that are set determine the point where the screen  will stop lowering or retracting. By initially adjusting the lower  limit, the screen will stop at the perfect location automatically  for maximum convenience. 
The upper limit switch is grey and does not need to be  adjusted as it is pre-set from the factory. If absolutely 
necessary, turning the grey upper limit switch counter clockwise will cause the upper limit to be closer to the  housing and clockwise will make the upper limit further away  from the housing. 
The lower limit switch is yellow and can be adjusted for  increasing or decreasing the amount of upper black drop on  your screen. 
To decrease the amount of black drop, first lower the screen  and turn the yellow lower limit switch clockwise twice.  Retract the screen then lower the screen again and where it  stops is the new lower limit. Repeat until the desired height is  reached. 



The first time the lower limit is being adjusted, it may take a few cycles for the screen to move up. This is normal and be patient as to not damage the screen. If the screen pauses during adjustment, wait 5 minutes for the motor to cool and continue adjusting. 
To increase black drop, lower the screen so it is fully  extended. Using the adjustment tool, turn the yellow limit  switch counter-clockwise and the screen will drop in small  increments without needing to cycle the screen. Continue  rotating until the screen is in the desired position.


The tension cord keeps the screen flat and under a moderate amount of tension horizontally. If the projection screen has ripples, then the tension cord may need to be adjusted. Wait 10 minutes with the screen extended and if the ripples are still present, then follow the steps below to adjust the tension cord. The tension cord is loosened when turned counter clockwise and tightened when turned clockwise. Slowly tighten the tension cord with the adjustment tool. If the ripples worsen, loosen the tension cord. A moderate amount of tension is ideal.

--- 16:10 PV Widescreen: This is the most popular aspect ratio for the latest WXGA or WUXGA notebooks.
Tip: Choose the 16:10 screen if you use a native wide screen notebook or wide XGA (UXGA) projector.
--- 2.35:1 Widescreen Cinemascope format: This is perfect with the new anamorphic lenses on the market today.
Tip: Select this 2.35:1 format screen if your application is strictly home theater Cinemascope presentations. 2.35:1 and 16:9 are the most popular format for Home Cinema.
