To put different backgrounds, here's some instructions I set-up a while ago:

Lately they have the drivers and control panel in one file now, so that's good. Also the AA is shut-off when set to app-pref. And if for some reason there is an app that can turn on the AA, then it has it's own off switch naturally.
You are turning off the 2nd display because of the flicker you get when changing the 3D settings, or is it a more constant low-refresh rate flicker?
I wish they extended the bar, it was nice when I was using a different trial program.
I basically hardly use the hydravision capabilities. The thing I love the most is how you can right click a desktop icon and save them. So if a game screws them up, right click and select restore.
I guess you are put off by the little things after being use to software from nvidia. I can relate in a similar way with Illustrator. I love Illustrator, but sometimes I have to use Freehand. It's a good program, nothing wrong with it, but it's interface and options are so different and little things that made things faster can't be found. I'd never give it a chance as I get too fustrated. While a coworker loves Freehand and hates using Illustrator.
Anyway, I'm done too. My Radeon 9700pro has served well over a year now and a year to come. And then, I see what out and Nvida might have the best card and I'd go with that. I'm no fanboy, I just go with the best. The 9700pro was the best since it was out 6-8months before Nvidias 5800U and then the better 5900 short time after.
