Hi there! Please kindly refer to User Manual (https://wiki.geekworm.com/images/7/7a/HDMI-to-RGB-LVDS-V1.1-EN.pdf) Page 6 - section "f) LVDS 6bit/8bit Output Mode Setting Command" for details.

LVDS 6bit/8bit Output Mode Setting Command

Input: test 103 id

Click "Send Data". The command is successful if the receive window displays the following. Reboot the board afterward:

cmd=103, p0=0, p1=0, p2=0

bit mode id=0x00, please re-start the board.

Note: Parameter "id" only accepts values 0 or 255.

0 = LVDS 6bit mode

255 = LVDS 8bit mode

The default LVDS output mode is 8bit
