How do you automatically switch between HDMI and composite resolution
Is there a way to automatically switch to an hdmi resolution when i plug an hdmi tv/monitor and also switch back automatically to a composite resolution (320x240) when hdmi is off or unplugged?

Re: How do you automatically switch between HDMI and composite resolution
by default, if you start the pi with a TV on the HDMI, it will connect to that.
no HDMI connected it will revert to composite connection.
i am not aware of a way to switch it while you are up and running, but a quick reboot to switch it either way isnt too bad

Get a small cheep LCD in your project https://www.sudomod.com/forum/viewtopic.php?f=22&t=2312
Wrap it all round a battery https://www.sudomod.com/forum/viewtopic.php?f=13&t=2292
Or use a custom PCB to make it really small https://www.sudomod.com/forum/viewtopic.php?f=13&t=2512
or make it really really really really tiny!! https://www.sudomod.com/forum/viewtopic.php?f=13&t=2919

Re: How do you automatically switch between HDMI and composite resolution
Yes i already know this. This wil work if you do not set a specific composite resolution. But if you set a 320x240 resolution in config.txt it will also be your HDMI resolution.moosepr wrote: ↑Thu Jul 06, 2017 7:31 amby default, if you start the pi with a TV on the HDMI, it will connect to that.

Re: How do you automatically switch between HDMI and composite resolution
yeah thats the only downside
you could leave the config.txt as it was, that way the HDMI will be able to do whatever it likes. If your theme has large enough font, you should be ok on the tft

Re: How do you automatically switch between HDMI and composite resolution
The only reason i need a fixed resolution on the composite side is for the command line texts to be readable.
I think i found the solution at https://www.raspberrypi.org/documentati ... itional.md
