HDMI out not working

[Jukebox461]

As you can see, I have almost got my phone set up. I drilled/screwed an in-car cradle to the side of my bookshelf and bought a USB Type-C to HDMI adapter, and a HDMI cable, and a HDMI splitter to my top monitor, so I can play games from my phone and easily switch between the two when needed. But I'm having problems getting the HDMI-out to work. I've checked the compatibility with apps like "MHL Checker" and whatnot, and it all says it's working fine but I can't get the TV to register a signal.

Setup ❤️

Error checking:
Selecting USB connection type - Defaulted to "Provide charge to device" when I plugged it in. Now not giving any option.
Everything plugged-in properly - Checked.
Hardware - Everything is brand-new, nothing's damaged.

Ports - Type-C works great transfering files. Transfer speeds match that of normal Type-C speeds for my USB 2.0 and 3.0 ports on my PC. Charges the phone well when I plug it in. (A lot quicker than what I expected comming from using Oppo's for a while.)

I've had problems all over with this phone since I bought it. Apps not installing, can't configure the app drawer/library. I mean... it looked good? The specs and the benchmarks sugested real potential. If you put 6GB of Pumpin Soup and an OctoPUS in a phone it oughta do better than this so far. I thought maybe I'd gotten a dud, but I ran the device diagnostics/tests out of the box and it said it was fine. But I guess it just tested for the external bits like the screen and buttons and whatnot.

Hi @Jukebox461;

Unfortunately the XZ Premium is not MHL compatible, you can use Google Cast or screen mirroring in Settings>Device Connection.

Well, it's got USB Type-C so, it is. MHL has been around since (at least) 2013. That's 6 years ago when I had a Galaxy note 3.

You can send any signal you want over any connection you want, it's just protocols, (physical restrictions permitting). Eg: IPv4 & IPv6 over USB type-A 1.0 if you really want.

I just don't get how they were too lazy to have it in the swipe-down menu or something. I'm really against rooting devices, but I'm getting really sick of realising that this phone disguised itself with a price bracket that it didn't belong in. Apart from being made of glass, I kind of want to go back to my Oppo R9s.

Don't get me wrong, it didn't have a few things. But the fingerprint sensor was in a good spot and it was $435AUD store price when I got it over a year ago, and this cost me $800AUD store price. Said it was market down from $1,000 so I thought "It's a Sony product, 6GB RAM, benches were good from the CPUs, it's in the right price bracket", but I'm already over it.

One decision just because of this - never buy a sony product again - ever! That's the only language they understand. Sony has fallen incredibly and their success in gaming has made them incredibly arrogant and some say stupid.
