VGA is analog, and DVI is digital, so that may be causing the problem. I'm surprised it worked at all, unless you have a converter inbetween that changes the signal.
If you can, try a regular VGA-to-VGA connection, or use a HDMI-to-DVI connection (the sound will have to be routed from the PC to the TV in a specific input. This will require a separate connection) to get the picture you're looking for.
I purchased yesterday the LCD. I connected my pc to the LCD thought VGA connector.
My pc has an nvidia 9600 GT card with DVI connectors so I used a converter to connect both through VGA cable (DVI to VGA connector from the PC and VGA connector to the LCD).
My desktop resolution is 1680 x 1050 since I have a 22" lcd display.
The issue is when I tried to play a game (ie resident evil 5) or play a DVD on my pc: often there is a frame at the upper part with a delays, it is like image being shown in 2 parts so you can see the line in the middle or when your video card is slow and textures aren't show at the required speed
Is this a normal behavior? Is there a way to troubleshoot this? Can be caused because VGA connection?
