My monitor cables all have rather hefty looking ferrite beads molded
into the cables and I have no RF problems. That's the way they were
delivered from Dell.
My son in law recently went to Best Buy to get a monitor for a new PC he
was building and found that he could buy an HDTV (TV tuner and all) and
interface it with an HDMI cable cheaper then he could get a similar
sized computer monitor. So, that's what he did. I don't have any RFI
experience with that set up except to say that I have no problem with my
own HDTV's.

Rf might be entering through the power and video cables. It could be that due
to your RF issues that many monitors might suffer this interference problem. I
would look into winding the cables around some torroids to see if this can
prevent the RF from entering the monitor circuitry. Also, you might investigate
putting a choke BALUN on the output of your transmitter, and a choke BALUN at
the antenna feed point if your are using coax. This addition might keep RF off
the feed line that could be radiating into your video cables. Jim, K6QE
