Maybe you use Windows, but it's not evident. Try this if you do. Run DXDIAG. On the rightmost tab, click it then in the OVERRIDE setting change it to 60.
best of luck,
I have recently bought a sharp LC20B6E Lcd tv with pc input. i have no problems using it with my pc but whenever i try to play a game just as it loads up the screen goes blank and the message "please check pc input" appears. I have tried changing resolutions but this has no effect and i know there can be problems playing pc games on a lcd tv, but is there any way round this?
thanks for an help or suggestions!
