I have a new T400 (less than 1 month old) with the shared memory Intel Graphics setup and I cannot get it to work with an external display of any kind.
I've tried 2 LCD panels (one widescreen, and one 4:3), 2 analog monitors, and a video projector without any luck. All of the displays I have tried work fine with my older Lenovo R61.
I've updated to the newest display drivers and tried working with the various settings under Graphics properties in Vista - Single Display (notebook, monitor), Intel Dual Display, Extended Desktop, etc. The best I got was a cloned image on the larger widescreen LCD panel that appeared for about 1 minute and then stopped. I recreated this 4 or 5 times, but the image would not stay on the external display.
