My computer won't let me change my resolution. What do I do?

I'm trying to increase my screen resolution. Every time I increase the resolution, and press ';apply,'; the monitor automatically goes on standby. When the monitor comes back on, the resolution is the same and my resolution settings are back to the way they were.

you may already be at the highest resolution your monitor or video card can supportMy computer won't let me change my resolution. What do I do?
It may be that your graphics card can't support a higher resolution.



Try restarting, that worked for me.
