Start with room behavior, not brand names
Decide how bright the room is during actual viewing, whether overhead lighting stays on, how wide the seating is and whether the screen must disappear every day. Those answers determine whether you need aggressive ALR, wider viewing, higher gain or simply the most mechanically straightforward format.
Shortlist dimensions that matter
- UST compatibility: lenticular/directional surfaces must be oriented for light arriving from below.
- ALR claim: useful for comparing intended positioning, but not a substitute for independent measurement.
- Gain: affects reflected brightness and should be considered with projector output.
- Viewing angle: matters more with wide sofas or off-axis seats.
- Case width and height: the physical housing can determine whether the screen fits your furniture plan.
- Controls: USB trigger, remote, app or voice control can make a retractable screen feel integrated rather than fussy.

Why a floor-rising screen is not always the right answer
If you own the room, never need the wall for anything else and want the fewest moving parts, a fixed frame is hard to beat. If the screen must disappear but floor space is constrained, a tensioned drop-down screen may make more sense. Floor-rising is strongest when furniture placement and clean wall aesthetics favor a low case.
