Sapphire Mayfair projector screen with radio frequency remote control This screen is not channel fix – please see the images below showing the end fixings The Sapphire Mayfair range of projection screens are truly a work of art. We use only the best quality materials and each one is tested at length before leaving the factory. Although it is difficult to convey the screen quality online. The triple laminated glassfibre surface is designed to lay flat with no curls extending into the viewing area. The gain is 1:1 which we consider best for modern projectors which have plenty of brightness. The viewing angle is very wide and the black border all around marks the image and improves your perception of the contrast ratio. The screen fabric has black backing meaning you can place the screen in front of a window and no light will come though the projector screen fabric. Fitting onto a plaster wall or ceiling is simplicity itself, thanks to the unique channel fix brackets. You will not find an easier screen to install. Please view the flash movie below to see more about the installation method. The price of Sapphire Screens is comparable with many lower quality offerings. We put our faith in the product by offering a three year warranty – this will give you complete piece of mind. Make sure you consider this important aspect before buying an inferior product. All Sapphire Mayfair projection screens come with a remote control. This model has an inline switch and radio receiver box around 1.3m from the casing. There is a further 1.3m of cable to a plug the other end of the control box. It will operate at up to 30 metres in the right conditions. Unlike IR, radio does not require line of sight. In situations where you want to fit an inline switch or connect this to a 240v relay then this screen is compatible (it has an inline switch on the control box). It has four core wires to the inline box (earth,neutral,live drop, live retract). Should you want an RS232 or closed contact this is now built into this screen. Please see the video below.
