I am using Dell U2410 associated with a Mac Pro 2009 through an ATI Radeon HD 4870. When I just pay money for it I observe a few times that the screen would merely turn out to be all scrambled noise identical to a TV set would with not any indication. It simply did it 3 or 4 times and just lasted a second or so, so I actually didn't disburse much concentration judgment that the problem was a loose-fitting cable. Seeing as then it not at all happened another time. The problems started come into view again a few days ago but this time something moreover is occurrence. The screen found flickering indiscriminately and regularly it happens subsequent to some time the monitor has been in make use of. Earlier to the flickering I can observe on black backgrounds a number of red pixels blinking arbitrarily over and done with the screen and then explosion suddenly the screen go away to PSM then straight away come around then reverse to PSM. I am out of ideas. Please help me.
