Re: Experience with odd KVM behavior?

Ive been dealing with some really odd KVM stuff recently.  I know that  
for one thing there are some servers that have a video card that puts  
out a much higher refresh rate and/or resolution even during POST.  In  
these cases I have monitors that just simply don't turn on because  
they can't handle the resolution.  The same can also be true for KVMs  
and the only reason why I know this is the case with these servers is  
because our IPKVM unit displays the screen much larger than the screen  
on my laptop for these servers while 95% of the servers display  
normally.  It could also be related to what type of cable connection  
the KVM is using.  A lot of KVMs are now putting keyboard/mouse/vga  
all within a single HD15 connection.  I've personally never seen any  
issues with that but its possible if the video card in the server uses  
an antiquated sync code of some sort.
