One of the most important factors in picking any monitor is whether it, 
or its PSU, generates noise, and how much it generates. An ideal 
condition is to be able to power from a 12-14V bus, so that you can 
drive it from the (hopefully) clean PSU that's running your radios.

Probably 6-8 years ago, our contesting team discovered some 24-in 
Samsung monitors that met this condition, and all of us have bought 
them. One is running as an extension on the laptop on which I'm typing 
now, from from sealed lead-acid that is being float charged by a linear 
PSU. The one in my wife's office is also powered that way.

There's detailed advice about this arrangement in applications note 
about finding and killing receive noise.  k9yc.com/publish.htm
