I won't be buying a LG device again and this is actually the second set of LG phones that I have bought for the whole family. We had G4's and G5's previously and now I bought 2 G7's and 2 Stylo 4's. The old G5 actually had the ability to send video over the USB type C port with an adapter cable and it also had an IR blaster built in so you could change channels on TV/whatever else. How features have been taken away with their newer high end phones. This is just crap.

I can't seem to get mine to work, I have the February 1, 2019 security patch. Just keep getting that diaplayport error. I guess I have to wait until Pie reaches my area, unless anyone knows of a.trick.

I know for sure there are usbc to hdmi cables that supports power delivery. Idk if the phone has this function enabled or what kind of cable is capable of this. Also the ideea with an adapter that has an extra port for charging.... Sorry to many wires for me.

Does the G7 output a 16:9 aspect ratio over hdmi?

I'm considering jumping from S8 to G7, but the hdmi out is absolutely needed. One thing that annoys me with the s8 is it outputs it's native aspect ratio, so my 16:9 monitor always has black borders around a 16:9 image. I know most tv's allow zoom, but my monitor does not.

Unlike most users, I can't get good wifi, so I rely on lte for streaming. If I don't stream via the phone, I hit my tethering cap in one night. Unless I move, I really need the right phone. I'm also looking at Dex solutions...

Does the G7 output a 16:9 aspect ratio over hdmi?
I've only used Miracast streaming compared to a hardware solution such as MHL (HDMI out) or SlimPort (DP/HDMI/DVI/VGA out), which are the two wired mobile phone display protocols (so if something says USB-C to HDMI, it is really referring to these standards). However, when streaming wirelessly, a new bubble overlay appears (only on the phone) that lets you change a few options (such as changing the aspect ratio from 19.5:9 to 16:9, screenshot included as attachment).

If using the default video player, the audio and video will only be displayed on the device that you are streaming to and you don't have to worry about orientation (other applications such as YouTube will play the video both locally and on the remote device, although the audio is passed through). Hopefully using a SlimPort cable (see below for why I'm suggesting this) would offer the same bubble since mirroring/streaming would be activated much in the same way.

I don't have a specific need for streaming via cable (everything just gets ingested to my local Plex server), but for those looking for one, I would avoid using anything made for computer products (such as Apple MacBooks), as those ports may physically look at the same, but have a very different pinout (while it's unlikely that anything would explode, such adaptors are not meant for this - I've specifically seen a person try using a G5 and a similar, albeit older, Apple hub to get output and charge and the charging did nothing). In fact, I came across a nice bit of text on the Wikipedia article (List of devices with video output over USB-C) while trying to figure out why this is working for some people and not others.

LG formerly supported DisplayPort on their LG G series and LG V series phones, but dropped support in the G6, G7, V35, V40 phones. With december 2018 software update LG enabled DispayPort output in G7, V35, V40 phones.
So it looks like we might still have horrible OS/security patches, but at least they threw us a bone here. If you already have an MHL cable from a phone such a Samsung or others, it will likely not hurt to plug it into your phone => display to see if it works. As far as charging, HDMI provides nominal power (not nearly enough to charge a phone while in use), and this direct input to output lines are called passive cables. There are MHL lines with active cables (another cable is spliced in to direct I/O line to provide charging power) that have the possibility to cause problems, but again they either should work or shouldn't. I hope this helps, and feel free to post any follow up questions.
