Bump a little... I'd like to remedy this, thanks

Thank you for the bump.
So, the pictures are very useful. It should be a software problem but it's the first time this has been reported on Mac as far as I know.
The logs show some puzzling things but nothing that can be connected to this behaviour.
I'm afraid that the only way to analyse this issue is to have the affected setup and debug it directly, I don't know how to help you remotely.
We'll give it another go in trying to reproduce the issue with a very similar display and setup.

Thanks, do you think it could be the hardware instead?

is this a vga adaptor? have you tried making sure it's not the vga cable? Also, some of the really cheap adaptors that I have bought just look bad over VGA. One adapter that I got works just fine and looks great over DVI but when I use the same unit over VGA to the same monitor, it looks like junk.

Thank you for the reply. I'm using a hdmi cable with a dvi adapter. I've used hdmi and dvi, they both look like this.

Hello,

Still not working...

I'm frustrated with this because as you can see from my join date, I haven't had a working second monitor in over 7 months. This sucks...
