I purchased the 'INCIPIO® USB-C™ DIGITAL AV MULTIPORT ADAPTER' @ my local Wal-Mart & it's worked fine. Obviously, you'll need an HDMI cable (not included) to go along w/ it. This unit supports USB-C™ power delivery. To use simply: 1)plug 1 end of your HDMI cable into your TV & the other end of your HDMI cable into the INCIPIO adapter. 2)plug the USB-C™ cable on the adapter into your G5 & that's it. I receive a mirror image of my phone screen on my Vizio without having to install any apps or change any settings on my phone. Also, you can charge your phone while using this adapter by simply hooking your charger to the INCIPIO adapter.
*Make sure the input on your TV is set correctly. Select the same HDMI input(in your TV settings)as the one your HDMI cable is connected to on your TV.
*Sometimes the connection is lost or is poor. I simply move the phone &/or adapter around, play w/ the connection until clear.
Good luck,
