I recently got a better screen for my computer. It's an LCD versus a CRT - the ViewSonic VA902b. I'm quite satisfied with it because it's better than the CRT, but it's a little discolored. It's got exactly the same problem as This Person, but they didn't get a good answer. I've tried to set several things with the monitor's buttons:

  • Auto image adjust
  • Color Adjust
  • Brightness/contrast

However I'm rather a headless chicken when it comes to those things. Perhaps the amplifier or something? - search

Can have many causes. But I will need more information. Can you post a picture of how far off it is? IE is it a screen calibration problem or is it a serious error in the display/drivers/cable/videocard hardware.

Some general things you can try.

  1. Check the cables and possibly test other cables and/or connection types. IE try a VGA if you use DVI.
  2. Double check what drivers you are using and see if a different driver doesn't have this problem.
  3. Try using screen calibration software.

Here is a photo: wstaw.org/m/2011/12/31/IMG_0007.JPG It's a very accurate depiction of the screen's appearance and color. Than you for your suggestions. I can only use VGA with this monitor. I will try screen calibration software at once. –  Richard Dec 31 '11 at 16:38
    
Could you recommend any screen calibration software to use? –  Richard Dec 31 '11 at 16:52
    
Your google is as good as mine. I haven't used any for KDE before. I only did photo editing on Windows. So for the linux distro's I didn't care too much unless it was obviously bugging me like this. –  Beanow Dec 31 '11 at 17:28
    
Looked at the picture now. That looks like a pretty strong color shift. It looks more like a loose cable then a calibration fault. Try fastening your cables again. And are there any alternative ways you can try to connect it? –  Beanow Dec 31 '11 at 17:36
    
I reconnected the VGA cable. There is no HDMI on the monitor, however my GPU has an HDMI out. If I got a VGA to HDMI adapter do you think it might work? –  Richard Dec 31 '11 at 19:05
