Esta guía describe como usar un monitor en el Radxa Zero.

Monitor HDMI

La mayoría de los monitores HDMI funcionan de primeras.

Especificar la Resolución HDMI (Por ejemplo: 1280x720)

La resolución por defecto es de 1920x1080. Ahora lo cambiamos a 1280x720.

Paso 1: Comprobar que el monitor soporta esa resolución.

rock@radxa-zero:~$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 3840 x 2160
HDMI-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 597mm x 336mm
   1920x1080     60.00*   50.00    59.94  
   1920x1080i    60.00    50.00    59.94  
   1680x1050     59.88  
   1280x1024     75.02    60.02  
   1440x900      59.90  
   1280x960      60.00  
   1280x720      60.00    50.00    59.94  
   1024x768      75.03    70.07    60.00  
   832x624       74.55  
   800x600       72.19    75.00    60.32    56.25  
   720x576       50.00  
   720x480       59.94  
   640x480       75.00    72.81    66.67

Paso 2: Obtener 1280x720 modeline

rock@radxa-zero:~$ cvt 1280 720
# 1280x720 59.86 Hz (CVT 0.92M9) hsync: 44.77 kHz; pclk: 74.50 MHz
Modeline "1280x720_60.00"   74.50  1280 1344 1472 1664  720 723 728 748 -hsync +vsync

Paso 3: Crea el fichero /etc/X11/xorg.conf.d/20-modesetting.conf incluyendo lo siguiente. Obtuvimos el modeline en el paso 2.

rock@radxa-zero:~$ cat /etc/X11/xorg.conf.d/20-modesetting.conf 
Section "Monitor" 
        Identifier "HDMI-1" 
        Modeline "1280x720_60.00"   74.50  1280 1344 1472 1664  720 723 728 748 -hsync +vsync
        Option "PreferredMode" "1280x720_60.00"
EndSection

Paso 4: Reiniciar el Radxa Zero y comprobar la resolución.

rock@radxa-zero:~$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 720, maximum 3840 x 2160
HDMI-1 connected primary 1280x720+0+0 (normal left inverted right x axis y axis) 597mm x 336mm
   1280x720_60.00  59.86*+
   1920x1080     60.00    50.00    59.94  
   1920x1080i    60.00    50.00    59.94  
   1680x1050     59.88  
   1280x1024     75.02    60.02  
   1440x900      59.90  
   1280x960      60.00  
   1280x720      60.00    50.00    59.94  
   1024x768      75.03    70.07    60.00  
   832x624       74.55  
   800x600       72.19    75.00    60.32    56.25  
   720x576       50.00  
   720x480       59.94  
   640x480       75.00    72.81    66.67

Bien. Ahora la resolución es 1280x720.
