I got an Nvidia GTX 970 a month or two ago. And ever since, I've been getting horizontal scanlines in FF14. Only this game. Everything else is flawless.

Now I tried a HDMI cable. It worked briefly. The scanlines were gone. Problem is, the HDMI cable stopped being registered the next day and everything I've tried is not working.

I have tried a brand new HDMI cable, uninstalling and reinstalling graphics card drivers and monitor drivers and even a DVI to HDMI cable.

VSync is on. Very first thing I tried.

Now I have two options. Is there any way to stop the scanlines or is there any way to get the HDMI working?
