Hello,
I have a 24 inch samsung monitor that has worked flawlessly for a year. Just recently isaw flashes of light ( looked like machine gun tracer bullets0 that showed up for a brief time. t
Then they showed up EVERY time i rebooted the computer. NOW therea are large areas of the screen that are covered with Colored Bands, BUT rebooting will sometimes make it all go away again.
I've changed the DVI cable ( two different ones) with no difference in the results. Now I switched to the old style RGB type cable with same results.
Could this be a Video Card Problem. I've owned computer for many years and never had a video card fail, so I'm not sure I'd recognize the symptons if I did have one going bad.
It's the "In and Out" nature of the problem that is so baffling....

Hey there. Sounds like it could be a bad chip inside the monitor. My buddy had a samsung that did the same thing. If you turn it off and back on it would go away and come back too. He had his in the sun all day though.

That sounds right. I sent it to Samsung Repair. There is a 3 year warranty on the monitor with shipping paid both ways, so I won't be out any money for a fix.

I REALLY like the monitor, so.........I bought another one just like it so I could continue with my photo editing while waiting for the first one to come back ( est 3-4 weeks).

I alternate between several computers and always feel like it's a step down when I have to use the HP LCD monitor on the alternate computer. It wasn't that expensive to add a second Samsung so I'm really kind of glad I had the problem to nudge me into getting another one so I have the same monitor on both computers.

Any thoughts on Calibration software? I "think" the monitor is pretty close based on pictures printed from the edited photos, but I have never used dedicated Calibrating software\hardware packages.

Grab this if you want a perfect color calibration.
