@mitu I did a small test. well I’m all confused. I swear you couldn’t change resolution in the raspi config anymore. Guess from the time I used the Kms driver from my last build. Well I went there and it allowed me to set a resolution and set the config.txt. Rebooted, but here’s the kicker. The hdmi port I was on, that booted to 1080p, now booted to a black screen acting as a second screen. And when I switched hdmi ports, to the one that ran at 4K 30hz, it was now displaying at 1080p. Still wondering why I was getting 1080p on the other port before. Guess at this point it doesn’t matter.
