I have discovered that if I set the Dell external monitor to be the PRIMARY monitor, then the X61 will drive it at full 1920x1200 resolution. The screen display is sharp, EXCEPT the fonts in MS-Outlook 2007! Another puzzle.
I just purchased an X61 Lenovo Thinkpad and have been very please with it. But in attempting to drive a 2nd, external display I'm running into some real headaches. Any advice on what I'm doing wrong would be much appreciated!
