In the spirit of being more constructive, I have added some to the wiki.
Basically, I beleive before people try messing with background colors, they should first try different resolution settings. I have added some screen shots to illustrate:

I have also added a new page illutrating the differences between 4:3 and 16:9 aspect rations and using /viewport.

The problem is that the people who will come here and create new threads complaining without reading existing posts are also unlikely to find this on the wiki. Perhaps if it gets bad enough a sticky on the forums for "Green UI tips / suggestions" could be useful.
