lately i've been trying to get a viewsonic g225fb that works. the first one flickered at anythng below 120hz expecially in the upper left hand corner, the second work find at first then started flickering in the lower left hand corner at 85hz.... so then i sent it bakc to viewsonic for repair. the day that i recieved it back it would start making a hissing/buzzing sound in the back of the monitor at 1600x1200 at 85hz, that being the optimal setting for the monitor so says the instructions. it wouldn't make the sound at ANY other setting, including those with even higher frequencies such as 160
