Hello!
This is a very good question! After looking into it a little further there are quite a few conflicting reports. However, none of the reports actually can confirm MHL/HDMI support. I would say based on the phones production date, and the movement towards wireless screen mirroring, I would probably say it does not. I can confirm it does supprot miracast and of course Chromecast usage. However, if you do want to go the cable route, you can find a USB C to HDMI adapter on Amazon from $13-20. Worst case scenario you purchase and it doesn't work, you can always return for a full refund. Given the small amount for the cable might be worth a try!
