RFI-quiet computer monitors? K6FOD on 27/6/18
Recently I was given a nice Windows 7 desktop computer that came with a couple of ASUS ~25" LED monitors.

Unfortunately, when I use the computer and monitors with an SDR (SDRplay RSPduo, software SDRUno), I get a barrage of vertical lines in the waterfall on many bands when the monitors are turned on. I've verified that the RFI is coming from the monitors, as it disappears when I briefly turn the monitors off.

I've taken a few steps such as wrapping cables around ferrite toroids, moving the SDR away from the monitors, etc. This has helped slightly, but in the long run I'd like to invest in monitors known to be RFI-quiet. Are there any out there known to be benign? I see another post here with a suggestion to create a registry of RFI-quiet appliances. This would be a great idea, and getting some suggestions on computer monitors would be terrific.
