[Elecraft] P3 to video

[Michael Blake]

Jim, I have two Samsung monitors.  One is a 23” 1920x1080 with one VGA and one HDMI input and the other is the 28” 4K display with one Displayport and two HDMI inputs.  Both have switch mode power supplies and I have never been able to identify either as a source of noise on my Flex 5000, Flex 3000, FLEX 6300, SunSDR2 Pro, Sun SDR2 NANO, QX1R, KX3 or K3s.

I have been quite fortunate in this regard as they have both served me well.

Several years ago, we were lucky to identify several Samsung models that run on a nominal 14VDC, and that work fine on the 12-14VDC that most of us have in our shacks (or on older linear 12V wall warts). Most newer models run at higher DC voltage, so to kill the noise they generate, we much find a suitable linear power supply for that voltage.
