Display identification and profile selection

[Ed Taft]

I purchased an external display (Samsung 193P) to use with my IBM ThinkPad X31 (Windows XP) while it is docked. I simply plugged it in, set up an F7-key display configuration for an external display only (at its full resolution, 1280 x 1024), and it worked fine.

Since I expect to do photo editing with this setup, I figured I had better calibrate the display and establish an ICC profile for it. This display has no front-panel controls but is adjusted with a software utility. So, perhaps unwisely, I installed the "monitor driver" software that accompanied the display.

This left the Windows display setup in a somewhat confused state. Apparently, it installed the "monitor driver" in place of the driver for the internal ThinkPad LCD display, rather than in place of the generic driver for the external display. The internal and external displays still worked OK, but their identities were scrambled and the ICC profiles no longer associated properly.

What I saw in the Display Properties was:

1. Samsung 193P and ATI MOBILITY RADEON
2. Plug-and-Play monitor and ATI MOBILITY RADEON

where (1) is the primary display (internal ThinkPad LCD).

In an attempt to restore some sanity, I went to the Advanced > Monitor > Properties > Driver menu for (1) and reinstalled what appeared to be the appropriate driver: IBM ThinkPad 1024x768 TFT LCD panel

However, when I look in Display Properties now, what I see is:

1. (Multiple Monitors) and ATI MOBILITY RADEON
2. (Multiple Monitors) and ATI MOBILITY RADEON

If I select either (1) or (2) and view the Advanced > Color Management panel, it shows that the default profile is whatever I have selected for "Plug-and-Play monitor". Also, I observe that the ATI Displays panel correctly identifies the internal and external displays; the confusion lies only in the generic Windows display settings.

With that long-winded background, here is my question:

What do I need to do to establish a sensible Windows display configuration, so that the internal and external displays are identified correctly to Windows and so that each of them associates properly with its corresponding ICC profile?

I recently received my L200p from IBM and it is awesome. I had the same or similar problem as you. What I did was I went to "Device Manager" and picked both monitor drivers present and uninstalled it. After a reboot, Windows XP detected and installed the correct drivers. Worked for me. You might wanna give that a try.
