The reason for this is that "EDID" is turned on in these systems, and it overrides what we have provided
when it comes to identifying the monitor from the monitor resolution, no matter how we try.
We must obstruct this, let us not let them decide for us.A VGA-VGA Adpater should be between the
hdmi-vga adapter and the monitor where:
pin 4 - Id bit 2 omitted
pin 12 - ID bit 1 omitted
pin 15 - Id bit 3 omitted
Only the RGB signal (1,2,3), the RGB body (6,7,8) and the synchronous (13,14) wires are connected.
I also attached a drawing to it.
If it indicates a defective resolution then our monitor really does not know it.
In this case, the h3disp command can set the resolution of your monitor from the SSH terminal.
For example:
h3disp -m 31 (800x480)
h3disp -m 32 (1024x768)
h3disp -m 33 (1280x1024)
