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.
Additional information : samsung monitor work perfectly with games and videos, no any flickering or laggs. Only Tv flickering randomly,so I cant watch anything there , even when i Duplicate screen or extend.
I have the same problem with the same card. Slight flickering every 5-10 seconds. Seems to be random. Extremely annoying
What I done sofar:
1. upgrade the nvidia card driver to latest stable version
2. use high speed hdmi instead of standard hdmi
3. tried all hdmi ports
4. switched to 59 hertz
5. upgraded BIOS on the motherboard P8Z77-V-LX to latest version
