- I also have a Nanao F550i and I also noticed the "rainbow effect" at
- 1024x768. But I also found a problem of my guitar amp buzzing and a small
- 'hiss' in the stereo speaker. It turned out that my halogen lamp was
- causing all this. Now, my "rainbow effect" only appears in certain color
- desktops such as aqua and so forth.
