I’m working with a RockPi4 using DietPi. Now I’m facing an issue with a projector which doesn’t get recognized at the startup and the only way I found it to be tricked is starting up with another screen and then switching plugs. I’ve just purchased one of those HDMI plugs that might solve it but, in the meantime and cause I may need it for other purposes what I’ve seen is the “soft” solution which I’ve seen that in other SBCs is as simple as adding “hdmi_force_hotplug=1” in the config.txt. The problem is that at least the distribution of DietPi I am using doesn’t have such file. So, does anybody know where settings like these and also, “splash_disabled=1”, so the boot up prompts don’t appear, can be set up in my environment?
Thanks a lot!
