I just bought a new Pi4 with 8GB of RAM. I run raspbian on it… It should serve as a teamviewer remote pc, but with any hardware periphery like monitor, keyboard, etc… just connected to LAN cable.
I just discovered that vnc and teamviewer work as long as the pi is connected to a monitor; when having plugged off the monitor, vnc and teamviewer do not work anymore, only ssh…
Somebody on the irc channel of raspbian said I should by a hdmi-emulator on amazon… I never heard of that hardware, but I surely can imagine what this does in theory… emulating as if a monitor would be connected.
My issues and questions to your are the following:
I can only find HDMI (normal HDMI) emulators on amazon… but not Mini-HDMI (as both ports on the new Pi4 are now “mini”)… or am I just too blind to find these?
Could I be really sure that this is the issue and it will just work when I put such an emulator on the pi?
Isnt there a software workaround for this? I remember that my pi2 and pi3 COULD serve as vnc and teamviewer servers, without having to emulate an output signal… I this case the pi4 is “worse” than 2 or 3… right?
Do you have any advice for me? I really would appreciate it and be very thankful for any help.
