===== How to set boot.ini to activate forcergb ===== | ===== How to set boot.ini to activate forcergb ===== | ||
+ | To activate it, add **hdmitx=forcergb** in bootargs. | ||
+ | <code> | ||
+ | setenv bootargs ${bootargs} hdmitx=forcergb | ||
+ | </code> | ||
+ | |||
+ | Here is the catch.\\ | ||
+ | The env **hdmitx** has other parameters related to HDMI CEC control.\\ | ||
+ | If you use CEC options, the env format can be **hdmitx=cecf,forcergb** or **hdmitx=cec0,forcergb**.\\ | ||
+ | |||
+ | The ODROID Forum user, wrxtasy from LibreELEC already implemented a good guide for this case.\\ | ||
