[TowerTalk] Quiet 27" monitors ?????/

[Pete Smith N4ZR]

I have two Asus 27" monitors, one two years older than the other.  I had 
to wrap the HDMI video cord from the newer VS278 around a #31 toroid 
(about 6 turns).  The older one (VP278 VGA driven)  didn't need one. 
There may be a lesson there.  I'm also not fanatical about RFI.

73, Pete N4ZR
