It has been said the new Samsung monitor display freezes up in an RF field above 500 watts. Recently I bought a Samsung Series 3 model S22A300B 22" (21.5" diagonal) monitor from Costco. I have tested it with both the KPA-500 linear and the Alpha 99 linear into my G5RV antenna (using my Palstar AT5K antenna tuner) SWR 1:1. Running the Alpha at 1500 watts has not caused any problems with the monitor. Neither amp causes a problem at all. My test was on 75 meters. I have not made this test on any other band yet. I am pleased with this Samsung because it automatically adjusts the image to properly fit the screen. I am using 1920X1080 resolution. Aspect ratio is 16:9. P3 firmware 1.12. Roy Morris W4WFB
