actually, I have both. the KVM dates from 2010 and came with
four cables and eight plugs.

here's the Whole story. last summer I dedided to switch to
all linux`in order to make upgrades simple[r]. since my brother
engineer [a retired ME] was too ill to help i hired a technician.
my "old-tao" (a homebrew AMD quad-CPU) had a broken USB.
this was how I realized that the USB was broken. with a new KVM
the home-brew still failed. I could ssh to<-> from, but not
watch it boot.
So
I finally
decided it was time to buys another Dell, new. somebody gave me
a used Dell dual. my server is a new dual from '09. used and
refurb'd and home-brew is not the optimal way. so my tech said
he would look for the best Dell quad he could find, and after 6
weeeks he brought over the 3010. [fact: this chap is self-taught.
but he got me a new kvm and blindly pluged things together.]]
whether the 3010 has ye-olden VGA jack =plus= the DVI, I dont
know. my guess is that the technician knows the diff. nutshell,
looks like whatever ghaphic chipset the computer had maxes out
a 5:4 screen-size ratio. I =will= try adding the mode line info.
thanks,
gary
