SLI causing color banding/color distortion on monitor

I've had an SLI set-up for close to a year now, first time this problem has shown up. As of yesterday, whenever I enable SLI, the colors on my left monitor become... messed up. Whites become yellow or blue (seems random, sometimes one or the other happens), bands of color instead of gradients. Color is perfectly fine on my right monitor with SLI enabled. The left monitor is both the 'primary' and the 'SLI focus'.

This has worked perfectly until yesterday, when this problem started.
To try to fix it, yesterday I re-installed the nvidia driver. It seemed to work. However, I did another restart today, and now the problem has returned. I'm very confused.

I have 2 Nvidia 560ti's. Using the latest driver. Dual monitors, one plugged into each GPU.

Please help!



The only thing that I can think of that 'changed' is that yesterday, the nvidia control panel asked me if I wanted to change the SLI focus to my right monitor (apparently it was on the left one). I pressed agree, and this problem started. However, there is no option for setting it back.

Oh, I should mention- SLI works just fine (no color problems) when only one of my monitors is on/plugged in.
