Why is my screen resolution messed up?

Updated graphics card messed up screen resolution?

• I was on steam and it said I can update my graphics/video card; so I did. The screen resolution got messed up and it won't go back to what it was before. There's not even the option to do that. Also I right clicked on my desktop>went to screen resolution> and went to advanced settings. It now says that my graphics card specs are unknown. Any way to fix this?

• Answer:

  you have to reinstall the drivers for it again if you don't have the video card driver cd go to the name brand web site and put your video card model number and download the driver if you can't do it in your pc since the Display is messed up the use another computer download the driver to a memory stick or a cd and passed to your computer
