Re: ghosting on LCD flatpanel through KVM switch

If you ever find an optimal KVM please let me know because I have looked high and low and can't find one.   I use a 24" Sun LCD and the biggest beef is the KVM won't support the right frequency at higher resolutions. The second is that the KVM won't properly transmit the video identifier signals to the OS so Linux says something like "I have no idea what display you have". Same goes for Solaris or WinCrap.
IF everything is perfect when the display is directly connected to the computer then make sure the video cable is lying in the same physical spot as when it is connected to the KVM (i.e. don't lay it next to a bunch of power cables when you connect it to the KVM).  If all that is OK then I know Black Box has an in-line video sequencer (I think sequencer is the correct name, not sure).  Anyways, it goes in-line on your video cable and you can tweak all sorts of video signals to get desired effects.  Don't know it will help your sit.
As fas a KVMs go I've always used Cybex (now called Avocent).  They seem to have the better products.  But when the whole industry product (KVMs) in general are less then optimal that is not quite a grand distinction.  Plus, they cost more than most. Sigh...

HTH, HAND

Has anyone experienced sub-optimal display on a Sony Viewsonic 18" LCD flatpanel through a KVM switch?  The KVM switch I have is pretty cheap.  The fonts are ghosted, although the redhat-config-xfree86 finds the monitor correctly.

BTW, I have the resolution configured to match the LCD display's native resolution, this is definitely a KVM-related problem, not something else (i.e., display is perfect if the video feed from the nVidia GeForce2 card on a VGA cable goes directly to the display and not through the KVM switch).  Oh, I'm running VGA not DVI.

Thanks.
