I don’t know anything about Roy’s converter but video format conversion can be tricky.  
The monitor is probably just more flexible in the signal it can accept.

Epiphany:  I found an LCD TV sitting here, it has composite in, and VGA in.  So I hooked both up to my coco at the same time, now I can just hit the "input" button on remote control to switch between VGA and composite signals at will.  Perfect, except:  The TV will not display the VGA signal, says "mismatch resolution."  But the manual for TV says it supports 640x480, 60hz.  I plugged converter into a normal vga monitor, worked perfectly, brought up the menu and it says 640x480 60hz. So.  Maybe TV doesn't support that res, and manual is wrong.  Or... could there be some other reason the converter output would not be recognized universally?
