I play with my PS4 on the TV or on the projector. Since I do not always want to change the HDMI cable, I'm looking for a device that allows me to control the TV or projector.
What kind of device do you need or are there other options?
An AVR can control the TV and screen
Something like that: https://www.amazon.de/...079FLNWJY/
or rather the: https://www.amazon.de/...07KSYS2L4/
It is with remote control
Av receiver with 2 outputs.
nice side effect. You could still connect loudspeakers and always enjoy 5.1 sound ;-)
