Hello, I have a fullHD hdmi 1920x1080 installed on a rpi4.
this screen resolution works perfectly, but at every reboot it is replaced with a lower 1280 x 720.
No changes also if, from the settings panel, I push on or off the button "headless monitor". Every time I reboot or repower the rpi, the resolution is always the lower.
Running raspi-config I correctly see "Mode 82 1920x1080" settings.
The /boot/config.txt shows:
but also commenting the 3 lines the result is the same.
A fresh genuine rpi installation recognizes itself the screen resolution and don't loose it.
Any idea?
Thank you.

Code:
# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1
# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=82
