    I just received a new T400 and T500 from Lenovo last Friday after waiting a month and a half.

    Last night, I noticed that the T500 screen has a stuck pixel in the middle of the screen. What is worse is that it is stuck red, which makes it stand out like crazy. I am going to try one of the open source programs that *may* fix it (i.e. udpix).

    Everyone that I have shown my T400 LED screen (Samsung) to has commented on how cloudy and discolored the screen is. I have had over 5 people look at it and say that the screen has a pinkish tint. These are the comments I receive when looking at the screen on its own. When I set it next to a Dell E6400 w/ LED (both 1440 x 900), they are shocked at how bad the Samsung screen looks. The E6400 screen is MUCH brighter, sharper, and true to color.

    It is really frustrasting that I just bought a T400 and T500 and both have glaring problems from the start.

    The screen quality (not regarding dead pixels) has been widely discussed on these forums. I would calibrate as David mentioned, but you shouldn't expect too much regarding the screen quality.

    In the case of the T400 WXGA+ LED panel, the problems you described are characteristics of that LCD. It's a crying shame too, because aside from the horrible contrast ratio (what affects if black looks black or gray to a large extent) and the vertical viewing angles, it's actually a very nice LCD that's improved on everything else Samsung had problems with in the past.

    The pink tint you describe is something that can actually be fixed with a proper hardware calibration kit. The cast you see is due to the native whitepoint of the LCD being so far off from daylight temperature and can be calibrated and fixed using the resulting .ICC profile. I wouldn't hold this particular problem against Samsung though, as most laptop LCD's (and a lot of desktop ones) are horribly off in one way or another and this is usually seen in the whitepoint first.

    UltraCow, can you elaborate on how I would go about using a calibration kit to fix the pinkish tint? I appreciate the info!

    A hardware calibrator will typically come with the software and documentation necessary to calibrate your monitor.

    There are several hardware calibrators on the market; most probably work the same way. With my Pantone i1 LT kit, I stuck the device to the monitor and ran the software to walk me through the process of adjusting the colors on my displays OSD and generating an ICC profile file for the monitor. I used the color control panel in Vista to apply the ICC profile for my monitor; though the software could probably do this too.

    It's an easy process, though it does take about 15 minutes to do.

    Pricing varies on calibrators too. You probably shouldn't buy one just to get rid of tint, unless you're a photographer. I imagine you'd already know about calibrating though if it was of serious professional concern. You might want to either find a friend that has a calibrator, or just mess with the display settings in the video card manager.
