Using a Dell U2413 monitor, Trixie fails to blank it (Lite console) properly on a Pi4 and a Pi5. If I add vc4.force_hotplug=1 to cmdline.txt the screen correctly blanks.
cmdline.txt also has "video=HDMI-A-1:1920x1080M@60D" in addition to "consoleblank=300".
The monitor is detected by the firmware as: "display HDMI HPD=1 EDID=ok #2 DISP1: HPD=0 EDID=none #0"
Is anyone else seeing consoleblank not correctly blank the Pi4/Pi5 console?
