For some reason, IBM can't seem to get its model information straight. For marketing purposes, this unit is called a T54A, but the model number is 9411-AW1. Neither the model name or number is marked anywhere on the unit. If you're looking for tech support on the device you'll need the model number. You'll also need the model number if you're looking for a driver, because using the T54A designation will get you no where.
Manuals disappear the day after the device is installed.
Better pricing can be had with non-IBM flat panels that have a wider range in the viewable angle.
