Hey guys My external display has been flickering everytime my machine goes to sleep then wakes up. I purchased a cheap monoprice MiniDisplay port because at the moment i was tight on cash (just purchased the MBP i7) Anyone know what the cause might be? I am going to see if a friend of mine will let me borrow his Apple Mini Display Port to DVi to use and see if it does the same thing. If it doesnt I will be returning my Monoprice one and spending an extra 20 on the real thing from apple. Just seeing what your thoughts are and if any of you have had this same problem. Oh and I tried taking a screen shot of the background because usually if its the vid card, it is the actual hardware itself and not just the display but when i took the screen shot everything looked good...no noise so I assume its something else.
