It should actually work fine over an analog connection (including via a
KVM, assuming the KVM is not too old.)  It works fine for me anyway.

One thing to watch out for when using a KVM is if a computer can get
information from the monitor even it is is not the active unit on the KVM.
Many newer KVM switches caches the response from the monitor, so all
attached computers can get information about the monitor.
Older KVM switches typically do not do this, so then you need to have each
attached computer be active when it starts to get information from the
monitor.
