- Speed Reduction System\n- Self-Locking Mechanism\n- High Quality Screen Materials\n- Dual Wall and Ceiling Mountable\n\nOptoma PMG+ projection screens are popular because they are inexpensive and\neasy to operate. Optoma Manual Screens offer several outstanding features.\n\nThe screens come in different sizes from 72” to 123” and also format 4:3, 16:9 and 16:10 to meet most projection requirements.\n\nControlled Screen Return\n\nOptoma PMG+ Manual Screens feature Speed Reduction-Retraction. Simply pull down lightly to release the locking mechanism, let go and the screen will slowly return to the casing.\n\nSelflock\n\nPull down the screen and hold for 3 seconds, then release. The screen will stay at the desired position.\n\nConstruction\n\nOptoma’s matte white fabric is composed of 4 different layers, including a sheet of weaved fibre-glass which helps stop static electricity and most importantly prevent wrinkles and waves. The screen fabric consists of a special material that helps prevent the loss of light, making it compatible with virtually every projector.\n\nThe fabrics are designed to be fire, water, and mold resistant and can be cleaned if required. The outside surface of the matte white screen has microdots that are made with PVC technology. This surface helps with creating the best possible reflection, whilst new advances in screen technology help keep our matte white screen flat and retain its shape and effectiveness over longer periods of time.
