Photoshop 7 trouble
 

So I just got a new monitor yesterday, a Samsung SyncMaster 957MB, and I've taken some time to adjust every contrast/color/gamma for my liking. Now, after I had done this I decided to load up Photoshop 7 to work with some wallpaper, when I noticed that the gamma/contrast of the picture in Photoshop was different from on my desktop and in every other program I have. It's much darker and all the colors are misrepresented.

This has gotten me quite perplexed, because I don't have any idea of what has caused this. I tried to reinstall the program, twice, but it doesn't work. I have no idea what I could possibly tweak in order to fix this. Please help if you have any idea of what could be done.

Edit: Nevermind, all I had to do was to adjust the RGB setting to my monitor... Doh! :D
