so at my club we have a g6 its tight, i usually just bring my external and play the night no problems, but lately, i been having crashes, and the screens just go blank. the other night it happened 2 times. so i did a bit of research and some people have been dling the new quicktime to solve their issues, so i decided to try that and it worked great... point of the story is, if you are having issues with stability, try doing that. ok good night. good luck. good job forum.
