Monitor or video card problem?

[Soul Daddy]

The visual on my home computer screen went all to [censored] at some point while I was sleeping last night. It looks similar to what it looks like in safe mode, only normal sized icons. Basically it appears to not have the full compliment of colors, as the bright colors are brighter and dark colors are darker than normal, but on a whole it appears very faded.

Does this make any sense? I can't really think of a better way to express it. I tried a screen print to show you what I'm talking about, but it looks normal, which I suppose makes sense.

Does this sound like a problem with my monitor or my video card? Both? Neither? Any and all help appreciated.
