Pixel Noise/Shimmering/Blinking?

[kepplah]

Today I noticed this kinda noisy effect on my monitor:

Certain pixels where shifting to black and back. The pixels that do this change when you move the image around the screen, but the location correlates to neither a physical pixel or a location on the image. I've noticed this mainly on bright contrasty images, but also in low light photographs as well where the exposure has increased. It does not do this when a solid color is display. (See the animated gif--I used stills from my camera in macro mode so sorry for the shaking and screen effect, ignore those.)

My monitor is a Samsung 245T, Nov 07, at 1920x1200 over DVI from a 7900GS running forceware 169.21 on XP Pro.

Anyone ever seen this effect? My Samsung 172x does not do this. Am I correct in pointing at the display? Turning MPA on or off has no change, nor does adjusting magic bright mode or brightness/contrast. Overdrive being too aggressive? Defective?


Otherwise this monitor is great. Color, viewing angle are top notch. I've really had to try to notice the ghosting problem people have complained of. It's quite minor, would not have noticed on my own. Do have a slight ringing sound from the inverter, but it's almost drowned out by my casefans, and if I had a typical louder computer it would be nearly unnoticeable.

Thanks

It could be artifacting from the vid card. Try the monitor on another pc and see if the problem persists there. If it does then blame the monitor.
Or try a different monitor on that pc and see if it still does that. If it does, it is prolly the vidcard, or bad drivers.

I would say try reseating the dvi cable, but usually a bad dvi cable, or one not plugged in well enough, will just drop you to a black screen for a second every so often, or not work at all.

I have a Samsung 245T and my first monitor was deffective with that exact same problem. It was probaly an issue with the Wide Gamut technology used as it only happened with shades of red like in your video. I got a new monitor and the problem was gone.
