My external sreen, LG w2241t, doesn't really like my unibody macbook. Every odd time it just goes completely black for less then a second (a couple of times an hour). This problem is known and quite well documented on the apple help forum, it seems the MB doesn't recognize some screens properly. Like, the refresh rate at witch it's running the display is 59.9 hertz when it should be 60 hertz, but maybe there are other problem in the recognition. There also seems to be no way to fix this as many tried and some got it troubleshooted with apple with no avail. So I'm wondering if anyone else is getting this problem on macRumours. I guess I should call apple, just that I don't want to troubleshoot for a problem I know there is no solution at the moment.
