This could be a hard one to diagnose the actual cause without removing the LCD panel. When used standalone without external monitor a decent workaround on my laptop (unless GPU performance is badly needed) proved to be using the mentioned gfxCardStatus app to force Integrated graphics. People say pressing on the MUX chip (square chip on right hand lower portion of the motherboard with laptop bottom side facing upwards) may alter the artifacts shown or have them disappear.

But if I select Discrete graphics (the AMD GPU) then the artifacts are back on the LCD. To force Integrated (Intel) graphics (external monotor not possible in that mode) then the LCD displays perfectly fine. I do not see any issues on an external monitor, only on the LCD. I diagnosed it to likely a case of failing Graphics Multiplexer GMUX chip on the motherboard, likely solder balls losing contact underside the chip. In my case (Macbook Pro 17 late 2011) the issue is green artifacts on display edges and shows up in dark areas of pictures/video. Is there any chance for this issue to be cable related, or changing the screen is the only way? Changing the screen is kinda not making me happy, thinking about the prices (where I live it's really expensive) I didn't dig deeper opening the display and trying to check the other end of the data cable, cause it seemed to be too complicated and dangerous for someone without good practice. I've tried to open the back lid and disconnect display cable from the motherboard, clean it and the connect back - nothing. I've tried hardware test and resets - no help. When connecting to external monitor - the colors are OK, so it looks like LCD or data cable issue. When the color changed to normal then mostly after shaking or closing/opening it started being green again. Now it doesn't help mostly (but sometimes though colors return). If I move black object around the screen - the green flickering shadow follows the object.įirst couple weeks the problem disappeared after a while - just don't disturb it ~10 min and the colors come back to normal condition. Now instead of black I see green, some dark colors turn into flickering green. The user was reportedly able to reproduce this problem on every floor model MacBook Pro at his local Apple Store.I have this issue on my MBP - after my laptop fell down on the floor the screen changed the color.

Freezing seemed to occur when CPU intensive apps coincided with running apps that caused Mac OS X to automatically switch graphics processing from Sandy Bridge's integrated Intel graphics to the discrete GPU. One user was able to pinpoint the problem down to the discrete AMD Radeon GPUs.
