![]() ![]() In that case, it may make sense to go with a more affordable roll-up screen and put the savings into paying an installer to mount a more conventional projector at the back of the room where minor waves and ripples in the screen surface won't be an issue. But, if you absolutely have to use a retractable screen for room design reasons and don't have the budget for a good tensioned model, you will want to place the projector as far from the screen as possible. ![]() Of course, you can always opt for using a wall or a fixed-frame screen to save money. But the sharp angle at which a UST projects can make even slight ripples more obvious with certain content. In fact, you may need a several thousand dollar screen to accommodate a short throw solution.Īny waves in screen material can cause obvious geometric distortion in the image, as shown on this hung screen displaying a grid test pattern. So, yes, you can use short or ultra short throw, but you can't use an inexpensive roll-up screen. The further away the projector is from a wavy screen the less impact the waves on the screen will have on the projected image. The solution to this problem is adding more distance between the projector and the screen. Especially towards the edges and the top of the screen. Any waves or bends to the screen cause severe distortion. This creates a requirement for an absolutely flat screen surface. These projectors throw an image at a very sharp projection angle. Think about what is going on with a short throw or ultra short throw projector. So, your screen, cheap or expensive, if it is non-tensioned (cheap ones aren't) will likely have or develop waves.Īll of this matters because of throw distance. These screens used tensioned cord down the vertical edges to pull the screen tight and effect a flat surface (see detail). To have any hope of success with a retractable screen and a UST projector, you'll need to make it a tab-tensioned screen, such as the Draper Premiere model shown here. I even remember this as an issue when I was in grade school as a kid. Retractable screens have had this issue as long as I can remember. Screens have a similar issue and the larger the screen the more prone to having waves in the material it is. Even if you pull them by the corners, they aren't flat. Think of your curtains or a shower curtain. What do you think?Ī: Most traditional screens have waves in the material. The only other option I have would be to put the projector on a high shelf at the back of the room, but that involves the usual long cable runs and installation concerns and won't be as aesthetically acceptable as keeping everything up front. Q: I currently have a flat TV on the wall in my living room and would like to mount a 100-inch retractable screen in front of it for watching movies from an ultra short throw projector that I would place on a console at the front of the room.
