Ultra Short Throw Projector Screen
Many people think you can project the image from your laser TV on a plain white wall and expect a 4K quality image.?While technically you can project an image using a UST on any surface, the picture quality degrades significantly without a specialized screen. If you want the true 4K UHD movie experience, especially in your well-lit living room, you need to use a specifically designed ultra short throw projector screen.
Ambient Light Rejecting
The main difference between a regular screen and a UST projector screen is that a laser TV screen has an ambient light rejecting surface that uses angular reflection. The surface of the screen essentially has rows of tiny ridges that reflect the light coming from the projector below while reflecting light coming from other sources, away from the viewer.
This ambient light rejecting property allows projectors to work beautifully even in rooms with a significant amount of light only adding to their value in the home.
If you watch the NFL on a Sunday afternoon or your kids want to play video games (not all UST projectors are created equal when it comes to gaming so far) with their friends during the day, an ALR screen is the way to go.
Lower Screen Gain
Ultra short throw cinema screens also typically have lower screen gain. Screen gain is a measurement of the reflectivity of the surface. The higher the gain the more light that gets reflected back to the viewer. The lower the gain, the more light that gets absorbed by the screen.
You might think on a laser TV screen that you would want to have a higher screen gain because that would give you a brighter image. In fact, lower gain is better because it further reduces the impact of ambient light hitting the screen.
The lower screen gain also helps eliminate hot-spots caused by the projector shining so brightly so close to the display surface.
