When a motorized projection screen is specified in a project, it is recommended to consider a tab-tensioned solution.

 

The price of a tab-tensioned motorized screen is frequently higher than a self-supported motorized screen, but it is worth the investment!The tab-tensioned screen will provide a perfectly flat viewing surface and a high-resolution image (4K, 8K, and yes, 16K).

It is important to consider that the amount of top black drop for a tab-tensioned motorized screen needs to be pre-planned.  The tab-tensioning cable relies on the complete (or near complete) deployment of the screen.  Only when completely extended does this cable pull the screen flat and hold it there for a flawless installation.  Measuring the amount of drop material needed before ordering will avoid any issues at the installation site.  If any adjustment is necessary, then it should be minimum.

Every tab-tensioned screen must have the overall width of the screen at least 1.33 times the height.   Wider is fine, but less width will lead to wrinkled corners.  If adding top drop material, then more side bordering is needed.

 

How do you do it?
 
Plan the placement of the screen case.
The height of the image should be tall enough to have the images clearly seen from the back row.
 
Plan the bottom of the screen.
The bottom of the image must be visible to all viewers without obstructions.
 
Plan how wide the screen needs to be.
The width of the image is chosen based on multiple factors such as content, projector aspect ratio and lens. As well as, if necessary to hide things or it is limited by the side walls.
