hi! i have a 2378DXU, with the 15" flexview and an ati radeon 9600 64mb.

fifteen minutes ago i noticed, after playing a game, battlefield 1942, that there was a black pixel in the middle of where quebec is on the default 1400x1050 IBM desktop background. so i got into paint and started painting colors to the background, red, green, blue, white, black. closed out of paint, still that pixel was just black. then i moved the mouse arrow over it, and the pixel turned white! i moved the mouse back away, and the pixel turned black again. got into paint, and double checked that with a white background the pixel was still black, it was. any ideas? are small-spot artifacts uncommon? after restarting the area was functional again.

this is strange. My first guess is, you have a defected pixel. not a dead pixel, not a color pixel. The pixel seems to work since it changes colors. The strage thing is, in order for it to be white all 3 primary colors (the 3 sub-pixels) are in action (red, green and blue). And as you said, it turns white sometimes. And when it is black, none of the colors (sub-pixels) are in action (dead pixel, when it's always black).

I don't know exactly what is going on with yours. To me that is pretty strange.

This would be very unusual - but...

Modern graphics controllers often use separate HW to generate the mouse cursor. If there was actually one bad location in the video RAM (very unusual) - then it could fail in all modes but cursor.

this "occasionally" stuck pixel happens to me too. it's just a white dot the appears after intense graphics usage, ie game, dvd, etc. weird stuff.

Haha, the "white stuck pixel" probably isn't a stuck pixel at all. It's actually for the trackpoint scrolling or something. To get rid of it, move the cursor directly over it (the cursor should turn into an arrow and scrollbar) and press ALT+F4. Then it should disappear.

Hope that helps! This confused me for the first couple of days I had my ThinkPad, until I realized this.

That stuck mouse cursor help is amazing. I thought I got one, but it was the mouse cursor.

I have a very similar pixel. It it is red when I turn my thinkpad on, but it dissaprears after some time. Once it is dissapeared, the pixel can have all colors
