Adobe Gamma used to come with Photoshop. It doesn't anymore, since AFAIK LCD's tend to not work well with it.
In the first "Norman Koren" link in
this post, there is a link to Quick Gamma, and a few other options.
About the ATI: A quick search turned up a few threads that suggest it doesn't play nice:
One,
two,
three.
You saved me a lot of headache! I removed the ATI Catalyst, and deleted all the directory files and folders. Did a registry clean and rebooted. I tried Adobe Gamma yesterday and did not find it helpful. My system has Vista and for some reason, I was having problems with it. I purchased Huey this morning - Spyder2Express was not in stock. I read a number of posts on problems and lack of satisfaction from Huey, but decided I've got nothing to lose.
Wow, what a difference ! The installation and the calibration took only minutes. The difference is remarkable. 
Thanks.
