I purchased a Viewsonic VX2770Smh-LED about a year ago and since two days ago I am seeing strange banding/overscan lines on only one side of the monitor. I attached an image, but it seems the banding does not show up in a screenshot. It occurs no matter what program is running. I have tried switching the HDMI cable that I use to run the monitor to my video card with no change. Is it the monitor or the video card, or is there any fix? Would appreciate any help.
