Last summer I bought a Samsung SuncMaster SA850 (24" - 1920x1200). It's been great until this week. Its colour and white look so much better than my old Samsung 226bw, which I am continuing to use as a secondary monitor. Over the past few days, there has been developing a flickering 'shimmer' across the right 30-40% of the screen. It is mostly horizontal lines jumping around, just on the right side of the screen. At first it seemed to go away after the monitor warmed up a bit, but now it is always there. If the screen is inactive, the flicker is worse and sometimes that whole section of screen can 'flash' briefly. Right now it's been in use for over an hour, and I can still see it.
I've tried taking screenshots, but it doesn't show up in the image, making me think it is purely from the monitor. I've tried switching cables and also output ports from my graphics card (amd 7970), but there is no improvement. I'm not sure if there are any other settings I could try.
Is my monitor toast? I bought it from NCIX (shipped) and I guess I'll have to ship it back as RMA?
thanks for any advice,
