You using a VGA cable to connect? I have a 37" Sinotec and I don't mind how the writing looks (doesn't look that bad anyway), I just want my series to be full screen. I have another pc for gaming with a 22", so I am sorted.
You need at least a response time of 8ms for gaming and most "cheap" LCD TVs don't offer this. Obviously, the lower the response time, the better. When above 8ms, you will notice "ghosting"...
