Just received my Spyder3 Pro today and created a calibrated profile for the HV121WX4-120 screen. The original X200 screen was too blue, and the HV121WX4-120 was a bit too red/yellow for my taste and the gamma was set to high by default. It looks perfect now after calibration. If glossy/matte is the only difference between HV121WX4-120 and HV121WX4-100, then the profile should also apply to the -100 screen pretty well.

To use it (in Windows 7): Go screen resolution->advanced settings->color management->color management...->tick "use my settings for this device"->add... and use the attached file.
Remember to go to msconfig and disable "c:\windows\system32\igfxpers.exe" on startup. Otherwise the intel color calibration will the profile on startup. Also see if there is a file called "Adobe Gamma" in the startup folder, I've read that it will also override your color management (although this didn't happen to me).
I will try to take some better pictures of the screen and post them here this weekend.
It turns out that the display properties, especially gamma level, of X200's screen change depending on whether it is on battery power or AC power (the same applies to my X61). So I uploaded two calibrated profiles, one created under AC power, and another one created under battery power. These profiles were created with a target gamma level 2.2 and color temperature 6500k.
If you go to this pagehttp://www.lagom.nl/lcd-test/gamma_calibration.php
you would want the lighter and darker bands should blend in at the height labeled "2.2", which is the targeted gamma setting. If you are using the profile for AC power, stare at those bars, and then unplugged your charger (with battery inserted!), you will see the gamma level (the point where all the strips blend together) slides to 1.2~1.4. If instead you applied the profile for battery power, and you are on battery power, plugging in your charger and will slide the gamma level all the way to 3.7.
There is no quick way to switch between profile in Windows 7 (perhaps some software will help). But I suggest you don't bother with the profile for battery power. In fact I do not recommend using it. It seems that when the X200 is on battery power, the display card will enter battery/power saving mode, reducing the gamma/contrast/color range it can generate. My Spyder3 Pro seems to have a hard time adjusting the gamma to a level it satisfies when on battery power. Consequently, the calibrated profile for battery looks pretty crappy, no matter how many times I try, although it did calibrated the a gamma level to 2.2 (seems to be achieved by reducing brightness).
On the other hand, the profile created for AC power still look pretty good under battery power, even though the gamma level is off. So I suggest sticking to the profile calibrated under AC power.
