Distortions on my secondary monitor

Here's something interesting.
I have two monitors on my mac. When I boot up, and log in, once the login procedure is complete the secondary monitor has distritions. It's like I am moving the mouse over sand and I am causing distortions.

I have not installed anything recently.

Now here is the interesting part, when I disconnect my primary monitor (thus making the secondary now primary), it works fine!

What could be the problem?
 
One of them is an ATI 128 RAge and the other one is a 128 Rage Pro.
The weird thing is this: When I am at the login screen, the distrortions don't occur on the second monitor. Only when I login do they start and the monitor becomes useless.
 
That's strange -- have you tried selecting a different refresh/resolution for the problematic monitor just to make sure it isn't that particular setting?
 
I have been using that setting since day one.
the other weird thing is that if I reboot, but login as a different user, no prob. If I reboot, login as me, distrortion happens, then logout and go to another user, then the distortion happens too! At the moment I am using one monitor (my windows monitor is bigger than my mac..eek!). If I find anything else I will post
 
after being stumped for a while, I decided to run a permission check, just for the heck of it. It did find problems which I fixed. Just for the heck of it I decided to run Diskwarrior, which also pit a few things in place. Now I rebooted and both monitors work fine, no distortions. My sceptre is just seen as a "generic" VGA monitor, but that is fine. Why would permission problems effect the monitor though??/ weird
 
Depends what Repair permissions did repair. May have been that the standard monitor profile for your second monitor had gotten set so that your system could not read it (why would it happen only when you login ? When the system loads services and such before the login screen, its all done by your system acting with the same access level as root) and thus it defaulted to a faulty profile. Probably something in that line.
