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.

I have exactly the same error on the opposite side of my monitor 1/3rd of it as you say. I have tried HDMI different Graphic Card and isolate every power supply plugged in and the problem didn't go away.

There was a suggestion on openeing the monitor and looking to internal wiring!

Have you had any success or resolution with yours.

Thank you.
