Hi everyone, I just registered to ask about the artifacting that's occurring on my newly purchased TV. I'm mainly using it on my PC with a HDMI connection and I'm experiencing a lot of red flickering pixels both on my desktop and in games/movies. I've already calibrated it fairly decently and most of the extra settings is turned off, is there anything else I can do about this problem? Something related to my software/hardware in my PC? I had no such problems with my previous 42" LG LCD.
