It's a bit embarrassing, but my main- "monitor" is a 42'' Full HD TV set, accompanied by a 24'' (real computer-) monitor. I tried to adjust the settings of the TV set as best as possible, so that it roughly matches the colors on the real monitor, but of course it might happen, that one or another image is a bit too dark or whatever.
Well, I'm not working professionally (anymore), so I can live with that, and I really enjoy the big screen!!
However I'll try to make the forest a bit brighter...
