Hello,

In general, all flat screen monitors are quiet.

Cathode ray tubes have much different characteristics and are more
likely to emit RF energy that is high enough to really disturb nearby
short wave reception.

A similar change of technology case is VCR vs. DVD.
VCRs use very sensitive tape reading circuitry at 0-5MHz region and are
getting QRM very easily from a nearby transmitter. DVDs are nearly
immune.

Just about no matter how we look at these developments:
Technology develops into a better direction!
