Hi,

I have set up a KVM switch between my desktop PC and Laptop in a docking station, and an LCD monitor.  I use the LCD monitor as an extended desktop display when using it with my laptop.

The issue is that unless I boot my laptop with external LCD monitor connected and KVM switch pointing to the LCD external monitor, the external monitor shows a fuzzy picture and the LCD monitor says that the signal is not the optimal 1650 x 1050 resolution.  Looking at the display settings on the laptop, it says it is outputting a 1650 x 1050 signal to the external LCD monitor.  Also, sometimes the external keyboard does not work in this situation too.

If I connect everything up and THEN boot my laptop, the external display is fine.  In both instances the laptop monitor always shows the correct resolution.

The way I have it set up is laptop on docking station, with DVI cable from docking station to KVM.  Then DVI cable from KVM to external LCD monitor.  Also have a DVI cable from my desktop to KVM.  All cables are a mix of DVI-I and DVI-D.

My equipment is:

KVM Switch - Rextron DAG-12
Laptop - Lenovo ThinkPad T520 with docking station running Windows 7
External LCD Monitor - Samsung Syncmaster 226BW
Desktop - Running Windows 7

Are there any obvious answers to my monitor and keyboard issues?


Cheers.
