I was wondering if anyone knew of a way to mirror my raspberry display to a TV using wireless HDMI. I searched and searched and I've found multitudes of blogs and questions about mirroring a phone display or a pc display, but none mirroring the Raspberry display itself.

I was wondering if anyone knew of any wireless HDMI kits out there that worked with rpi, or of any projects that leverage some. Any version Pi is acceptable. I currently have a Pi Model B but I'm looking to upgrade.

I'm only asking because I am in the planning stages of making something similar to the Super Game Pi, and I would love it if I could flip a switch, and play on a big TV via the HDMI port, but still remain in my chair, or across the room.

Thanks.

EDIT

I've found this question Does the Raspberry Pi 3 have wireless display capabilities? and it seems that screen mirroring is harder than it sounds. I've also looked into Picast, but its not what I needed. Along with Piracast, and its also not what I was looking for.

Would having one Pi run a VNC server and the second Pi connect to it work? I don't have any experience with VNC servers.

This is a little pricey but I would think you could just use an HDMI splitter like this one. One side goes to your normal display and the other goes to a wireless HDMI transmitter like this to your TV.

  • I saw those, do you know if they are compatible with the pi? I don't think I'd get one regardless, 150+ is a little pricey for something I probably wouldn't use alot. – Hypnic Jerk Sep 19 '16 at 14:30

About the software part, i strongly recommand the tiny program fbcp. Basically, it copies everything going through the HDMI output, /dev/fb0 (even disconnected) to one internal display, i.e. a touchscreen on /dev/fb1, via GPU.

Just launch it and stop it via a tiny GPIO interface and you have your switch :)

Provided you found some wireless HDMI system, this should fit your needs.
