[RFI] Computer monitor RFI

[Alan Beagley]

The Sony 15" monitor connected to the computer I am using with my rig 
generates an enormous amount of RFI: S9 signals at intervals on 20m and 
up, the intervals depending on the screen resolution I set. The 
interference stops if I turn off the monitor or when it blanks after the 
set timeout interval.

The video cable has its own integral RFI filter, and I have tried adding 
a choke to the power cord and an additional one to the video cable, but 
to no avail.

Any ideas?
