Wow, where to begin... As soon as I upgraded, the desktop went to a glitched screen, like a nintendo game that needs to be blown and reinserted. I could only see the curser when it flashed on screen, but only for a second. Since I couldn't find the soft reboot, I did a hard reset. I let it sit. I turn it back on, same thing. Hard reset again. Same thing. I'm getting pissed. I grab my SL disk about to reformat when the next reboot got me back to the desktop. Now, however, it's very bright and washed out. It's like someone set the white balance way too high. I turn off the card using gfxcardstatus tool and everything is great! The colors are back to their usual color. I turn back on the 330m and the colors go back to washed out... I tried all the "color" settings in the display menu, but nothing seems to help. Anyone else having video issues with their MBP 6,2, mid 2010?
