I have a problem with my new T510 showing 'sparkling' pixels in black areas on an LCD monitor. I am driving the monitor with a BYTECC DisplayPort to DVI cable adapter. A few sparkling pixels show up after the monitor has been on for a while.
I should point out that I have two setups: one at work and one at home. Two cables. Two Samsung monitors and two adapters. The setup at work with a newer 1920 x 1200 Samsung monitor does not show this problem. The setup at home with the 1600 x 1200 214T monitor does show the problem.
I have swapped the adapters, and the problem remains at home on the 214T. My Dell Inspiron 9400 has never show a problem like this in four years of use on that 214T and does not show the problem now, using the same cable (but not using the DisplayPort to DVI adapter). So I do not suspect the cable or the monitor.
Today, I updated the drivers for the T510. No change. I don't suspect the T510 video card because it seems to work fine with the monitor at work. So I'm running out of ideas.

have you tried a different dp to dvi adapter?
If you mean a different make, no. I've tried both of the adapters that I have (swapped work with home) and the problem stayed with the 214T monitor at home. I tried adding a magnetic noise choker to one of them. Didn't help.
