Yes..its very strange to see this question here this AM since just last nite I found out how bad my two CRT monitors are aon HF. My dell laptop seems fine. Since I am about to begin building up some SDR hardware, I'm looking for any solutions other than having to buy an LCD panel.

I doubt that you will be able to eliminate RFI without replacing the two CRT monitors. Fortunately, LCD monitors have become remarkably inexpensive. And with LCD monitors you will have a much sharper display, more desk space, and less heat in your face (lower energy consumption).

I sure don't miss my CRT computer monitor. Now I no longer have to change the monitor's resolution/refresh rate to shift the monitor's harmonics off the frequency I'm listening to. It's very difficult to prevent harmonics radiating from a CRT monitor's horizontal sweep circuit. It's a 28,000 Volt triangle wave!
