Black edges

[Guest]

My computer all of the sudden has these black edges that are about an inch
wide on both the left and right sides of my screen. How do I fix it????

Change your refresh rate and resolution.

There must be some buttons on the front of your monitor for adjusting
display. Once you start it, you should be able to find an adjustment
for stretching the display horizontally. I think it should work for
resolving your problem.
