Certainly everyone's color channel adjustment setup is going to be a bit different. I'm somewhat curious on typical experience. I've a got a light gray wall (Repose Gray from Sherman Williams paint, SW 7015) behind my TV. I'm using a 5 inches short of 5 meters of WS2801 LEDs from AliExpress. My Hyperion.NG calibration settings are shown in the attachment; far from perfect, but as close as possible for my TV/wall. Surprises: White is calibrated somewhat pink rgb(255,160,150) Yellow is calibrated a burnt orange rgb(200,100,0) Uncalibrated-raw-yellow appears very green. Irritations: Red is certainly weak/dim when shown next to other colors. Yellow is really weak/dim, probably due to how much calibration was done on it Thoughts I'm betting my green and blue burn hot/bright. Betting red burns dim If I were to invest in some different LEDs for better colors, where should money be spent?
