I recently started getting a black line about 1/2 to 1 inch wide from the top to the bottom of the screen. It usually happens when sliding the screens back and forth to view the different monitor screens at the office. It will go away if I minimize or run the mouse over the area. Thoughts?
When toggling back and forth between screens, the new screen will often have a thick black line (1/2" to 1") from top to bottom on the screen that was not visible. I have a newer computer, Samsung monitors. This just started a few weeks ago. When i switch from full screen to window in the View drop down, the problem went away.
