There are two variables fb0_width and fb0_height in the '''/boot/orangepiEnv.txt''' of the linux system, which can be used to set the width and height of the Framebuffer. The default setting of the linux system is fb0_width=1920 and fb0_height=1080.

'''<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:
