I've been using Windows 7 64-bit on my Thinkpad X61 for several months without problem. (I am up to date with the released version of the OS). Recently, it started booting into very low resolution mode -- only about a quarter of the welcome screen is visible. Within this small view, the mouse pointer can only move in the top half of the screen. I'm able to log on "blind" and then my desktop is also on low resolution. If I hit WIN-P and choose "duplicate" display (even without an external display plugged in) I am restored to the normal resolution for the laptop, 1024x768. If I then close and open the laptop, however, it is returned to the very low resolution mode. I am also getting very low resolution (300x400) on my external 1680x1050 LCD monitor unless my laptop is also open and I am in dual display. Likewise, coming back from sleep, suspend, or hibernate, puts me back into the very low resolution mode. I don't believe I've changed anything in the system in the last several weeks. Any ideas how to troubleshoot? I've searched around for this problem and not found it precisely. Video card is Intel 965 Express. Driver Version 220.127.116.117 8/6/09. My installation is fully up to date with all Windows Updates and is constantly updated for virus software (eSet).
