Hi, for a week now I've been having a problem. I've tried everything, and checked with different software. Updated everything in my computer. All I can think is it's my Aver T232hl. Off and on it sticks at the top of the screen and flickers there. I can use my mouse or touch to do other things (probably since it's multi touch), but the cursor flickers like heck when this is happening. If I turn off that screen it stops. My other screen is a Wacon Cintiq 21UX. I've checked with that too. The only thing that seems to be causing this is the Acer. I haven't moved the monitor and it hasn't been dropped or hit at all.
