Changing Display Output
The Open-Q 2100 Dev Kit is shipped pre-configured to HDMI display. If you need to change the display output
between LCD and HDMI, use the following commands to switch the display. Note that you also must switch the
HDMI/DSI select DIP switch.
For OSD LCD display
adb reboot bootloader
fastboot oem select-display-panel osd_disp_fwvga_video
fastboot reboot
Switch the HDMI/DSI select switch (S3400-1) to ON to route display signals to the LCD panel. See
section 3.9.1.
For HDMI 720p mode
adb reboot bootloader
fastboot oem select-display-panel adv7533_720p
fastboot reboot
Switch the HDMI/DSI select switch (S3400-1) to OFF to route display signals to the DSI-HDMI bridge
chip. See section 3.9.1.
Please, note that once <fastboot oem> feature is used it will be the only way to switch between HDMI and LCD
modes unless the device is re-flashed.
