I recently bought this used graphics card (MSI Hd 7770) off of ebay and after installing drivers, plugging it in with the power pin it had a really grainy display, it looks something like this:

sorry for drive image, I don't know how to really show it to you with the URL.

I'm running 1080p on an HDMI cable, 16:9 I believe
