I just got an unexpected missing-required-file error when compiling a program and decided to reboot. After rebooting, my primary monitor — I have a two-monitor setup — became blurry.
The display has been working fine for almost a year, and I did not make any changes to its configuration recently. In particular, I did not change the video card, resolution or refresh rate. It's an LCD, so degaussing isn't the solution. I have confirmed that it is set to the recommended resolution and refresh rate. The only non-blurry thing is the OSD; even the Windows XP boot screen is blurry. The second monitor in my display, which is the same model and is attached to the same video card, is still working fine.
How can I restore crispness to my monitor?
EDIT:
Yes, the BIOS screen is blurry as well. As far as I know, no unusual events, such as booting into safe mode, have occurred recently. The connection is DVI. Will update later with the results of switching the monitors, can't do it right now.

Check that all the wires are connected properly, try re-plugging every connection. If that fails, try a different cable and a different computer - that should give you some idea of where the problem is (screen DVI port, DVI cable, or computer DVI port).
From the information you provided, it seems unlikely that it's a problem with the computer's software or the screen's electronics.
