I'm trying to get some help with a X200. When I undock the machine the screen resolution drops to 4bit 640x480 and will not hold any further changes to return the resolution to it's prior setting. I click "undock" from the start menu and wait until I'm prompted that it's safe to undock. I've performed a BIOS update and video driver update with drivers from Lenovo's website this past week. I have also tried using a different docking station but continue to see the same result. And further options would be greatly appreciated.
