I just got my U2410 today and I was trying to see if there were any dead pixels on the screen. Are the pixels on this monitor supposed to be SO little? I used a black background and I went over the entire screen but couldn't find any obvious spots. Then I decided to get my eyes really close to the monitor and then I could see these tiny tiny spots that had a different color, sometimes green and sometimes shifting colors as I moved my head around. I thought to myself "hey the pixels can't be SO tiny right? They must be dust particles or something." So I decided to get a piece of cloth and try to rub them off gently. But I couldn't get them out.

So are these really dead pixels or my eyes are tricking me? Are they supposed to be so tiny on a 1920x1200 24'' screen?
 
Lets put it this way your 1920x1200 monitor has... 2,304,000 pixels.

It could be a stuck pixel, but yes it could very well be a dead pixel.
 
lol - are these tiny "different color, sometimes green and sometimes shifting colors" all over the monitor?

If yes - it is just the antiglare coating on the monitor.

Search and download a program called dead pixel buddy and try it on a white background to know for sure. It will be painfully obvious where dead pixels are.

With normal eyes - you should easily be able to spot a dead pixel 10" away from your monitor. You don't need to be close enough to sniff the monitor to spot them.
 
Use this:

Each pixel is made up of a red/green/blue sub-pixel and this program will display a full screen of each color. Look for any black spots all over the screen, which indicate a dead sub-pixel. Make sure it's not dirt by wiping that area with a cloth (gently) if you see any of these black spots.

For stuck pixels a black background is your best friend. When checking for these get close to the monitor and only look straight on. The ips panel's blacks glow when viewed from a slight angle, that's why it's best to look closely and straight on, moving your head to different positions around the screen to ensure what you are seeing.
