*UPDATE*
So I went over to the nvidia forums and started a thread about these horizontal lines -
this one and there is another thread also over there on the same issue -
this one. Anyway, after doing that I submitted a ticket, then contacted live support and was told they (nvidia) would be investigating this issue. You can visit 1st link I posted to view a transcript of the chat with the live agent. Today I was contacted by someone from nvidia, and was told they would be further investigating the issue and contacting asus to try to get it resolved. Here is the response I received:
Hello,
Thank you for your bug submission. This is a known issue we are currently investigating with ASUS. The problem has been confirmed to be unique to this particular LCD panel. As We suspect the issue is related to our dithering mode, and that this particular LCD panel is also doing dithering. The symptom may be a side effect due to the panel doing dithering itself, and our GPU doing the dithering again. We are in contact with ASUS to confirm with the panel manufacturer about the panel built-in dithering. I think once we know more about the specification of this LCD panel then we'll have a better idea how to resolve the problem. Thanks for bring this to our attention.
So hopefully there will be a fix coming soon.
