It's a cheap 4-port KVM switch that cost ~$25 a couple of years ago.
Supposed to go up a decent resolution and I really only need
1920x1200. The unit looks like this one
www.geeks.com/details.asp?invtid=MT-401UK&cat=NET though I didn't buy
it there (same model number). The one to which I linked claims
1920x1440 max resolution so I realized I'm pushing the limit.

When I hook up the X300 to my Dell 24" monitor, it's seen as a
"Generic Non-PnP Monitor". I'm not sure if that's different than when
it's connected directly. I have it set to display only on the external
monitor. Win 7 though I had similar trouble with Vista and XP.

The monitor's native resolution is 1920x1200 but when I choose
1920x1200 on the X300 I get a blank screen except "D-Sub: Can not
display this mode". The same for 1920x1080 and 1680x1050. I get a
display (sometimes distorted, with ghosting characters, sometimes with
a little cut off on the side) at 1600x1200, 1440x1900, 1400x1050, etc.

My assumption was that the switch is poor quality, or the supplied
cables, or both.

Right now I've got a Dell desktop (Win XP) hooked up to it too. Though
it has fewer resolution settings, the Dell displays at 1920x1200
though a bit blurry (and ghosting) and sometimes shifted left (if I
switch between resolutions a few times, eventually I can get 1920x1200
without the shifting).

To check for a bad port/bad cable, I switched the cables to the two
machines at the machines' end, with the same result.

While I may be expecting too much of a $25 KVM switch, is there
something about the X300 that would cause the monitor to report it
can't display its native 1920x1200, while a Dell using the same cable
and same switch, will get a display (irrespective of the quality)?
(e.g. is the X300 somehow recognizing that the display quality is
substandard and refusing to show it).

Right now I'd be happier with a 1920x display from the X300 through
this switch, even if the sharpness and general quality were as low as
from the Dell.

Thanks!
