Gnome sees my monitor correctly, Kde doesn't. I noticed this when I typed "init 4" instead of "startx" like I normally do after logging in. In Kde I had to "adjust all fonts" to 150. And then some of the fonts in certain places weren't visible.
But, in Gnome, all fonts are visible without any adjustment.(So far, from what I have seen)
So, I guess I will have to get used to Gnome. Why there would be a difference between Kde and Gnome, I have no idea.
