I have a liveTV issue. Switching to a 4k channel and back to a 1080i channel changes the colors. Everything seems overcolored. The 4k channel always looks ok.
I guess dmesg is not the right log? What do you need?
dispinfo 1080i: http://ix.io/1Lo3
dispinfo 4k: http://ix.io/1Lo4
dispinfo 1080i: http://ix.io/1Lo6 (weird colors)
It seems that the colorspace and the resolution stay after 4k->1080i?
UPDATE: Now suddenly (without doing anything) the screen turned black and when it returned after 2s the color is okay. I ran dispinfo but I didn’t get a new link…
So maybe nothing changed in the logs but the colormap did? Weird?
