ok.. i have a Mag 810FD monitor. My problem is that when i turn on my computer, log into windows, and open up Internet Explorer, mozzila, or try to explore the hard drive, my screen goes black! i have waited up to 5 minutes and then i figured that i had to TURN OFF the monitor and then turn it back on! i have no idea what happened (this has been hapeing for about 6 months and i just installed a new HD and now its doing the same thing.
