Bug Description
Two days ago I upgraded to 22.04 LTS.
My laptop display works fine but my external monitor(HDMI port) has strong pink coloration in grey scale / white areas of display. I put up a picture of a NTSC colorbars. On the laptop display it is correct. When I slide it to the external monitor it has distinct pink color in the 70% grey scale bar.The white bar is correct as are the cyan, blue , yellow, red, etc. The pluge (program lineup guide) black bars display correctly, thus no contrast problem. The only visible problem is the pink in the 70% bars.
I suspected the monitor might be at fault, but I rebooted into my Windblows 11 (dual boot) both displays were again correct, as they had been in Ubuntu until the Upgrade to 22.04.
That is the extent of by ability to analyze the problem. I suspect something in the HDMI but have no way to check further.
