I have a Lenovo Thinkpad T420. I use it in three situations:
- Connected to docking station with two LCD monitors at 1280 x 1024.
- Connected to docking station with two 21" LCD monitors at 1680 x 1050
- In regular laptop mode (using the native monitor).
In all three situations, my screen resolution gets adjusted automatically, and the monitors (or monitor) appear as they should.
The problem is that, in the first situation, the desktop gets extended to a third monitor (VGA) even though no monitor is plugged into that video card. I have to manually turn off "Extend desktop to this display" or my cursor gets lost in this region of my desktop.
Is there any way to prevent this from happening? It never happened until I moved my workstation from one part of the room to another, which involved unplugging everything and re-plugging it back in.
Settings on startup
Settings after turning off "Extend destop to this monitor"
Why won't it remember this?
EDIT
Screen capture of my display settings for situation #2:
Monitor #1 and #2 are reversed. Could this be the reason for the problem?
