Lightroom 3 dual monitor problem - grey boxes

I just got myself a 22" secondary monitor but I can't get lightroom 3 to properly work with it. I can't get any images to display on the secondary monitor, it's just grey boxes.

If I drag a secondary window over, all images show up for a couple of seconds then they disappear. You can see the images of it in the next post since I can only attach two images per post.

I'm running windows 7 64bit
30" 2560*1600
22" 1680*1050

Here's an example of me dragging over the previews, they show up for a couple of seconds, then they disappear. I can't see any images no matter what module. But the slideshow module works if I set it to display the images to the second display.

This is really annoying

Problem with your (left) monitor profile I think.

Thank you it works perfectly now I hadn't noticed windows recognised it as a PnP monitor, it works fine after I installed the correct profile. I also rotated the monitor 90 degrees CW.

Pictures look cute. Hope you will post some in Wildlife forum.
