Ok it sounds like you changed the master crystal in the CoCo.  This
would speed up the entire machine including the video output.

Instead of hacking your monitors to match the speed of the faster CoCo
why not make the video output section of the CoCo match the original
speed of the monitor.  i.e. cut the trace that supplies the clock to the
video circuitry and "glue" in the old crytsal (plus or minus any
dividers) from the CoCo on to the cut trace/pin.

This way you have fast processing and original video signals.
