[Elecraft] P3 SVGA external monitor freezes - RFI?

[mike]

When using KPA500 my external monitor (and the P3 display) often freezes,
sometimes up to 5 seconds, after I transmit. With the external display
disabled, the P3 does not freeze (and incidentally it refreshes much faster
without the ext monitor enabled.) I also notice a slight flickering of the
monitor screen while transmitting. I take this to be a RFI problem. I have
added four snap on ferrite beads on each end of the VGA cable. The monitor
is as far away from the amp and feedlines as I can get it and all equipment
K3, P3, KPA500, KAT500 are bonded to a ground bus. This is not unique to
this monitor as it happened with a different smaller monitor I used before.

This has always been a problem, and I would like to eliminate it as it is
very disruptive to is usefulness in finding a clear spot to break through a
pileup. Not sure what else to do. Has anyone else had this issue?
