Limit the OrangePi resolution after boot without graphical interface

BlackPotato

Hello fellows, I would like to limit the resolution of screen after booting in OrangePi Zero Plus 2 H5.

I have search for some time and did not found any method to set this.

What i have tried:

• I tried to set the variable disp_mode in orangepiEnv.txt
  

• I tried to change the dtb file as i found in this reference, but i could not find the screen0_output_type variable in the the dtb of the file sun50i-h5-orangepi-zero-plus2.dtb
  

Notes: I have to set the resolution to 1024x768 even in a monitor with higher resolution available, but the orangePi is setting the resolution to the maximum available.

Any tips in how could i do this?
