Hi everyone! I have gtx 670 FTW card from evga. Normally PC is connected to my samsung monitor by DVI cable and it is ok. The problem is if I connect my LCD 42 Inch Westinghouse Tv by HDMI as additional screen (so both screens on) this tv is flickering time to time like once every 40 seconds and it is annoying, I was wondering if there any problem with card or tv ? I tried to change 3 HDMI ports on my LCD tv and it still flickering. I am very sorry for my English and grammar. Help me please.
