Can't change display resolution

With a Latitude D630 and a docking station I have an extra monitor. The Latitude has it's own resolution which I can change but the extra monitor stays at 640X800 or whatever Safe Mode gives you. I can pull the slider to higher resolutions but when I apply it then it snaps back to 640x480.

I had another monitor on it last week and this monitor did whatever I wanted it to do.

The video card is the nVidia quadro NVS 135M on the laptop.
Why won't the resolution stay even up to 1024x768?

Has the monitor been properly identified by the Control Panel Display applet?

I have a similar setup with a D620. I'm running the extra display at 1680 x 1050 on the external monitor and 1440 x 900 on the notebook.

Try connecting the monitor directly to the D630 without using the docking station.
That will eliminate it as a source of a problem.

Ok, but I need the dock because that is how I work. Anyhow-----------

I plugged in another D630 with the nvidia Quadro display adapter to see if it was the computer. I did this: I made my external monitor the primary and I have extended my windows on this monitor. I also have the extended thing checked on monitor 1(laptop) as well. Now I can change my 2 external monitor's resolution. So I can use it that way and will ignore the laptop that I can extend onto. I may lose my cursor once in awhile over there but I will get used to that.

Now I will try my orginal D630 and try to do the same.

As it is there are too many variables in the mix. Narrow the problem by eliminating the variables one at a time. The only way to eliminate the dock as a problem is to test without it. After that hook it back the other way.
