Yeah, the moment I started troubleshooting I killed the 2nd mon and ran the TH2G by itself on the 9800. This helped obviously.

Yeah, that's the problem with pulling a machine out of an old render farm.

Yes, and there is that funky thing with the TH2G where certain refresh rates are not supported at certain screen sizes.

As unless these are very recent - they are likely to be the source of bugs in graphics.
But they might not. There are too many combinations of things.

What's the advantage of 10.4.8?
