KVM monitor resolution blues

So the LispMac has been resurrected with a new disk and a restored motherboard (and of course the $5000 MacIvory). I'm moving the Quadra 800 over to an ADB KVM so that it can share its VGA connection with the LispMac. Trouble is, now the Q800 (ordinarily running 8.1) only sees 640x480 now that I've moved the VGA converter to the KVM instead of connecting it directly to the Q800's video port. The Monitors control panel gives me only one resolution and only "Recommended."

ISTR there was an extension or control panel to force a particular resolution, but the name escapes me. Anyone remember? Or am I nuts?

Re: KVM monitor resolution blues

I didn't find such an extension (but I am quite sure something like that exists). What I ended up doing was connecting it back to the VGA converter, and then inserting a VGA->DB15 converter after that. I get the correct resolutions now, though the image is a bit ghosty (though I suspect that's the switchbox).

Re: KVM monitor resolution blues

Yeah, sorry I don't remember an extension that does that.  I know someone made one specifically for the 8500's onboard video to get higher res, but that's about it.  Did switchresx go back that far (presumably without the x)?
I mostly do what you describe, putting the vga/db15 converter on every machine, which is a bit unfortunate since you need N instead of 1, but oh well.

Re: KVM monitor resolution blues

Switchres? Are you booting each Mac when it's the one hooked up to the KVM?

I've got a medium size pile of converters from various mixed lot eBay snags if you need any.
