Hi, I’ve installed android 9 on radxa zero. I have 2 monitors (old and new). But the new monitor does not work, the monitor resolution is 1024x600. And my radxa current resolution is 1366 x 768.
arzak@hp:~$ xrandr
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
VGA-0 disconnected (normal left inverted right x axis y axis)
eDP connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 174mm
1366x768 60.00*+ 40.00
1280x720 59.97
1152x768 59.95
1024x768 59.95
800x600 59.96
848x480 59.94
720x480 59.94
640x480 59.94
HDMI-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
I changed to 1024x600 or 1024x768
arzak@hp:~$ cvt 1024 600
# 1024x600 59.85 Hz (CVT) hsync: 37.35 kHz; pclk: 49.00 MHz
Modeline "1024x600_60.00" 49.00 1024 1072 1168 1312 600 603 613 624 -hsync +vsync
then reboot the device, but the current resolution is same. It’s not changed.

The new monitor only show almlogic logo, but the android 9 was successfuly booted. I can run adb shell and run some command.
