LOL ... sorry icemansin, that was really funny question. I understand that you are quite new with the LCD screens, so I will try to explain you this. Don't worry, you will get there at the end UDPixel is unable to find the dead/stuck pixels for you. You have to look for them with your own eye and use those square flashing boxes on them in order to possibly bring them back to life. In that sense, you have to fill the screen with the uniform colour (just click on the colour tabs from UDpixel) and then start to look for them. Sometimes, with such tight dot pitch, it's very difficult to find them at first instance (if they exist). However, even if you find one or two dark/dead pixels I doubt that you will be able to see them in normal monitor usage, as they are not distracting. If you have stuck pixels which are visible on the black background (they are green, blue or red) that can be probably more distracting. Anyhow, hope this will clear the mistery for you.icemansin said:However i was using the UDPixel program from this link http://udpix.free.fr/ and i set the Flash Window setting to 10 and pressed start and it came up with 8 flashing boxes from the top left in a diagonal line? Does this indicate 8 dead/stuck pixels? I cant seem to notice them when changing to any colour it seems.
