That nebula looks simply great; definitely conveys a nice and dark mood.

I basically have three monitors in my house:
13-inch 640x480x8 - 1990

19-inch 1600x1200x32 - 1998
21-inch 1920x1440x32 - 2001 (this is the one I normally use)
I have noticed the same problem with all the monitors and graphics cards I have tried; most games are completely unplayable due to the fact that things are too dark to see anything. I can alter the brightness/contrast levels, but that makes things look sort of "washed out" and worse in general. My brother doesn't have any problem though, so I guess it's just my eyes.

(my vision is terrible in terms of nearsightedness, but I guess I have trouble with brightness too
