Hey guys I bought a ten foot VGA extension cable off ebay and it was working great, but now all of a sudden when I plug it in to the lcd screen in the projector it says no signal input. It's weird, because my computer still detects it as an analog display, but can't read the specs of the monitor anymore.

Any ideas??

That also happens if you exceed the refresh rate of the LCD.

I think I fixed it, but I'm not sure. I actually did it by increasing the screen refresh rate. The screen got a signal but it still only reads it as an analog display. Thanks for that tip though.

VGA is analog not digital. DVI is digital.
