If you are expecting to be able to adjust the top black drop on this screen to stop earlier than unrolling to the end of the fixed top black drop, this is not possible as of December 2021. Elite stated that they had a mechanical top black drop adjustment but it was causing motors to strip and fail to retract the screen. They removed it from their documentation and most of their web content, then slapped a warranty void if removed sticker over the adjustment screw.
In the case of a UST especially, this is a problem because if your wall or ceiling mount math is planning to reduce the top black drop, too bad, you can't and that means you need to either place your projector on a lower surface or reduce the image size to less than the 120 you're paying for. Given that USTs need to be in the space typically reserved for center channel speakers, and given that the center speaker is the most important in a surround configuration, finding a cabinet that will take both a large center channel and a UST is a challenge.
If you have the expectation of saying "Alexa, turn on the TV" well, sorry Bob. That isn't going to happen. The screen will trigger open using the RF remote, but the screen will open all the way. In my case that's six inches too far. So after firing everything up, I then need to use the remote to try to stop the screen at the right height. That cuts into WAF and causes the kids to yell "Dad, come fix the TV!"
Elite plans to redesign this screen next year to allow the remote to be programmed to a custom length. There is no release date for this fix, and customer service stated that there will be no retrofit.
If you are considering this screen and you have a tight vertical tolerance due to wall or furniture height, wait for Elite to provide an adjustable stop screen or buy shorter furniture.
