I have an LG L226WT and a 20" Apple Cinema Display connected to a brand new Mac Pro.

Both monitors (in the same configuration) were running on my old PowerMac G5 before.

The Cinema Display works fine, colours are good, so is light etc.

The LG first had ghosting (severe at that) and this morning the colours are totally out of whack. Looking at some photos I had taken a week ago and colour corrected on the G5 now look like a child painted them (on the LG monitor, on the Cinemadisplay they are fine).

It's not the graphics card either. If I take a screenshot on the LG and look at it on the Cinemadisplay the colours etc. are correct, but the LG is right now pretty useless to me. I tried to calibrate it but the end result is pretty much the same, it just does not seem to want to play nice.

I don't think it is the DVI cable, as it is securely screwed in and in the same location as on the PowerMac, turning the monitor off / on seems to resolve the shadow problem but not the colour issue.

Anybody have experienced this? Any tips outside of trashing the LG and buying a new screen?

    Hi there,

    Ive had the same ghosting issue you've been experiencing with your LG.
    My LG model was the 204wt model. The ghosting was fixed when i zapped the pram.

    However, it only worked for a week or two and the ghosting returned.
    I am at a loss with your colour problem...
    Ive definitely given up on LG, and am looking towards other options.

    I had the same issue on my LG W2452T that I bought to replace my failed Cinema HD. What I do to overcome the ghosting is go to Display in System Preferences, select the Display Tab and in Resolutions I select any of the available resolutions. Once the monitor has adjusted to the new resolution, I think put it back to it's maximum setting 1920 x 1200. No more ghosting!

    Not that it will help much but I have the same monitor the LG and have never had an issue with it. I am using DVI-D connection for mine. Are you using a VGA cable on yours?
    I also have dual monitors setup and never had any color issues or ghosting on any display.

    I would try changing cables around and see if that does anything.
