Is it possible to output to both HDMI and another display?
-
I know the Pi 4 can do 2 HDMI displays and clone the output to the 2nd one, but can a 3 B send the same output to both HDMI and a Pimoroni Hyperpixel 4.0 at the same time?
I found a relatively easy way to switch between them on a reboot, which might do, but having both could be nice. https://forums.pimoroni.com/t/hyperpixel-selective-output-eg-on-boot/5193

Maybe there's such thing as an HDMI splitter?

@IceChes1 There is. It will allow you to view an HDMI output on 2 monitors. I want to view HDMI output and a display on the GPIO pins simultaneously. I'm thinking it can't be done, but we'll see.

Is that possible?

Not looking like it from what I can find, I'll have to go with the autodetect on boot script, that will have to be good enough.
