Ok so here's the deal. In the past month I've been having a lot of issues with my 30" Apple Cinema Display which I bought last year in January with my new Mac Pro. The first time I got the problem I was quite shocked to be honest. I booted up the system and when I sat down on my chair in front of my desk the screen flickered and then turned off. When I got up it turned backed on. Then it started flickering. So I restarted my Mac Pro and everything went back to normal so I ignored the problem. Then a couple weeks later while playing under Windows XP during Far Cry 2, I got severe artifacting which is a sign of a graphics card failure and I also got the message saying NV4 Display Driver failed. Anyway I rebooted and everything went back to normal. Now after a couple of days, my screen issues with the flickering and turning on and off randomly started again. Called AppleCare and they fixed the problem by making me reset the Video manager by unplugging all cables. Problem is today the problem came back. I called Apple and they said its quite alarming and told me to bring in the display to the Apple Store. I reset the video manager again and everything works but I can't keep doing this each time. I really need my Mac Pro for school so do you think it is worth bringing in to the Apple Store? What do you think the problem might be?
