Help! Monitor has red and blue pixels and lines everywhere. Looks like 3D!?

I was playing online everything working fine then the desk I was using collapsed a bit due to the desk being collapsible the monitor falling on its side- not onto the ground or anything just onto the desk I quickly picked it up and the screen had red and blue dots everywhere and had low quality. I restarted it a few times. Checked the cords. Let it rest all night. Nothing! It is still all messed up. I just want to know what is wrong with it and how I can fix it. It s a older monitor from about 2010. I will get a new monitor if needed but I just need to know what is up .
