Pete,
Sorry to hear about the noise from the Asus monitors.
For anyone in the market, the 2 monitors I bought in 2020 and 2021 are RF quiet.
They are Acer S271HL model 27", and a feature I like they autodetect and turn
on anytime the laptop is turned on.
I paid about $170 for each one on sale at the time brand new.

Subject: Re: [TowerTalk] Quiet 27" monitors ?????/
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.
