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.

please point somewhere more appropriate.
I recently redid my station operating position layout and upgraded to
two 27" inch LED monitors
Much to my dismay so far 3 different manufacturers of 27" monitors
all had significant spurs or birdies . ( Dell, Acer and HP) .
Particularly on 14-28 MHz . I Keep taking em back to WorstBuy and
trying something else. My older ASUS 23" from 7 years ago were deadly
quiet. These are definitely video related not power supply hash. I can
change their frequency by changing the refresh rates in windows setup
. While torroids in the leads "helps" it is far from eliminating it.I
have tried many different torroid mixes and i am still far from
eliminating it
So my question can any one recommend a recent 27" led monitor
purchase that is is spur free? Make & model number please
