Problem with the Belkin Flip KVM

I bought a KVM to open up some more room on my primary desk.  Now I have my 1 Dell E207WFP (awesome wide screen - I'll never go back.  I can't!  I won't!)  and 1 keyboard and mouse.  Pushing the little Belkin Flip button swaps from my laptop to my server.  Nice, however, when I boot up my Vista laptop, it detects the monitor as Unknown Monitor with a max resolution of 1,440 x 900 instead of the 1,680 x 1,050 that the E207WFP provides. 

Solution:  I swap out the monitor cable back to the laptop, boot, then swap it back to the KVM.  Why don't I just swap in/out the monitor/keyboard/mouse and toss the Belkin?
