Very interesting. I just couldn't resist trying out a little experiment at work: I disassembled a 15" LCD panel(1024x768 TFT, we design and produce LCD monitors) and placed the LCD glass plate on an overhead projector. The LCD backlight PCB can be disconnected from your main LCD electronics. The result is not that bad, though the light o/p and uniformity is far inferior to the expensive LCD projectors. See attachment. Actually the 15" LCD was still too big for the normal A4 size O/H projector. 14" LCD might be better, might try that sometime later. I had 1.5m distance O/H to wall, and ended up with a 2x2m wide screen. It is a little tricky to fold the LCD panel drive flex PCB backwards. If you are careful, the experiment should not be distructive for your LCD panel. Please note that the LCD panels of normal LCD monitors have a max temp rating of 55 degrees C. It might be wise to mount the LCD plate with a little air pocket above the O/H glass, and put a fan at the side.For flight simming, you might want to place the O/H such that the light comes out just above your head. All considered, it might be a very cheap alternative to the LCD projector if O/H and 14" LCD can be aquired for reasonable price. RgdsRoland
