15" MBP i7 with AMD Radeon 6750 Graphic card - video artifacts

Hello -


After I connect a projector with HDMI, the projector starts having broken up/disrorted images at start up. I brought my machine to the genius bar once and the tech used a few combo keys and it cleared the video memory and was like new again.


Does anyone have the key combo?


Better yet, is there a permanant fix?


Thanks in advance
