Hello, Finally, it's been two years of having this issue right i got a laptop with it. I thought this is only last chance of finding the answer. So, I have been struggling with having games in full screen where it became unplayable. It causes a lot of vertical lines and sometimes horizontal lines. Also, there are a lot of times if i receive any colors related to RED, bright green, orange, and bright orange or anything like that then my full screen would start acting funny like flickering or colorblinding. I have tried many. many attempts to fix it. I will list fixes as much as if i can remember.

1. Uninstall drives, Reboot, installing. Even in safe mode too...

2. Updating drivers to latest version.

3. turn verital sync on in ATI option, and even ingame options.

4. Trying without Crossfire to run only single card on one game..

5. Clean video cards by blowing the dust. it's really clean.

I think that's all i can remember. i admit, i am not really stupid about this. I have been polishing this laptop alot. i hate to have problems in my laptop and alway get it fixed immedately.

Back to the point, Only solution i found is turning games into windowless or windowed screen. All of those issues stopped. IF UNLESS in FULL SCREEN, they will come back. I dont like it, it's so frustrating... Can you help me?

Here's the detail of my laptop:
