Display Issues

Hey guys. I have just built my first rig. Everything seems to be going great. Except for when i play League of legends, I get horizontal lines that flicker from time to time. I am running a gigabyte hd7870... And using a 23" Samsung hdtv (via hdmi) Also for some reason my audio redirects itself from my headset to my tv.

Looking for help......

sounds like it may just be screen tearing

try turning on vsync and see if it stops

I turned on vsync and it did it once the entire game. Could it be the hdmi? Or the hdtv? From what i know all of my drivers are up to date.... Its getting really annoying.

If you have a spare monitor or cable you could try them.

I myself hate HDMI, I would switch to DVI
