With the versions > listed below, was the loader in ESP updated too? Good question. I'm not entirely sure if my 13.x installation is not update from 12.x. It probably is. IIRC I followed the update procedure recommended, but certainly 13.0 -> 13.0-p4 is just `fetch` and `install` matter. If you like me to update ESP bootloader, I'm happy to follow your instructions how to do that. Anyway, my 14.0-CURRENT is fresh install to separate drive in an attempt to duplicate issue also on current to report it here. So gop get reports this (manually rewritten by hand): - FreeBSD 14.0 - current: EDID 1920x1920 1920x1920 1920x1200 1920x1080 1600x1200 1600x900 1280x1024 1280x960 1280x720 mode 4: 1024x768x32, stride=1024 frame buffer: address=d0000000, size=300000 color mark: R=00ff0000, G=0000ff00, B=000000ff - FreeBSD 13.0-p4: EDID 1920x1920 1920x1920 1920x1200 1920x1080 1600x1200 1600x900 1280x1024 1280x960 1280x720 mode 4: 1024x768x32, stride 1024 frame buffer: address=d0000000, size 300000 color mark: R00ff0000, G=0000ff00, B000000ff > >> >> (1) 13.0 release >> (2) 13.0-p4 (stable) >> (3) 14.0 snapshot from 2.9. >> >> The behavior is still the same.
