I have a Pi 3 and regular desktop computer with a single (DVI input) monitor. The desktop and Pi both have HDMI out for video. I use an HDMI > DVI cable to connect whichever device I want to use to the monitor.
Thought a simple HDMI switch would be nice to save the hassle of switching the cable back-and-forth but it doesn't seem to work with the Pi. The message on the monitor says "Input not supported".
Is there some special consideration that needs to be given to the Pi3 when using an HDMI switch? From the reviews, it seems like a lot of people have this switch working between a TV and gaming console just fine.

config.txtin some way - see documentation - I would suggesthdmi_force_hotplug=1,hdmi_group=1andhdmi_mode=16to start with ... pick a different mode if your monitor isn't 1080p of course/boot/config.txt. I have the Acer (ACR-G236HL) monitor hooked up to the HDMI switch which, I assume, means the pi is using the hdmi settings under that section. Does it use the same section when the switch is inline?
