There are two variables, fb0_width and fb0_height, in '''/boot/orangepiEnv.txt''' of the Linux system. You can use them to set the width and height of the Framebuffer. The Linux system defaults to fb0_width=1920 and fb0_height=1080.

orangepi@orangepi:~$ '''sudo vim /boot/orangepiEnv.txt'''
disp_mode=1080p60
'''<span style="color:#FF0000">fb0_width=1920</span>'''
'''<span style="color:#FF0000">fb0_height=1080</span>'''|}
The reference values corresponding to different resolutions of fb0_width and fb0_height are as follows::
