Question : Problem: Monitor and KVM switch compatibilty

I have the following:
Monitor: Acer AL2216WD
Input Signal: VGA (Analog), DVI-D (Digital), HDCP
Maximum Resolution 1380 x 1050
I currently use the VGA cable but will be getting a Digital Video card and changing to DVI-D

I would like to get a KVM switch and am currently looking at the D-Link DKVM-2K a mini 2 port which only supports the following:
The DKVM-2KU supports VGA, SVGA, and MultiSync monitors at up to 2048 x 1536 resolution

Are they compatible??

Answer : Problem: Monitor and KVM switch compatibilty

Not if you want to use DVI-D. This is a digital signal and no doubt dual link as well.
VGA is analog which the KVM you posted supports. The two are not compatible.
If the video card is DVI-I then it would support an Analog signal and an adapter from DVI-I to VGA could be used.
