Banana pi m2 ultra 1080p resolution

Continuing the discussion from How to set 1080p:

how to change bananapi m2 ultra screen resolution 1080p use bpi-tools. I download it and installed and what now? /uEnv.txt - doest work in every iso image.

Yes i got it .: 1.wget 2. sudo dpkg -i banana-bpi-tools*.deb 3. mkdir BPI-Tools 4. cd BPI-Tools 5. sudo bpi-tools --upgrade 6. sudo bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m2u/BPI_M2U_1080P.img.gz 7.reboot

now we have 1920x180 resolution screen

Hi, I tried this way but my monitor can’t display the 1080p — how can I undo it? thanks

I need a Resolution 1680 x 1050 x 60Hz. How can I do this? regards Jurgen
