recently purchased a new Mac Pro w/ mountain lion 10.8 and I am using my Apple 30 inch monitor.  When watching video or browsing certain websites, my monitor will flicker grey and sometimes lock up.  I am a video producer so this is quite frustrating...I figure it is the grphic card or I am missn a plugin or driver update? help!

Check for and install updates using software update. Reset SMC and PRAM.
