What's up with my Parallels 8 Windows 7 VM?

I installed Parallels 8 last week and am using my Boot Camp Windows 7 partition. For the past few days the colors on the screen have been all screwed up. It doesn't matter whether I'm in Full Screen mode, Modality, or Coherence. And I've booted it multiple times, same results. Although the issue isn't there when I'm playing one of the games shown in the toolbar. Does anyone know what it might be? I've got no clue. Thanks

Note: I don't have this problem when I boot Windows 7 from startup.

Try changing the color depth in windows display settings to match the host display settings...

Oh wow haha thanks, I didn't see that option in the advanced settings earlier but I double checked and it was right there.

Problem solved! Thanks!

Check your video settings, both in the VM software and in Windows, it looks like something just isn't translating properly. Maybe the VM is trying to accelerate something it shouldn't, or maybe it's the other way around.

Tinkering with Parallel's settings may fix this issue, and if it does, post back with what you did.

Thanks, I tried playing around in the display settings in the Control Panel. When I click "Calibrate Color" it says that it can't calibrate a display that has a color bit depth less than 24 bits per pixel. My MacBook Pro's screen is 32 bit, according to the System Information. Does that mean it's a VM thing and not a Windows thing? Haha I'm kinda clueless.

And I'm not sure which settings I would adjust in Parallels. Do you know where these might be?
