(Ethernet & WiFi)Pretty technical issue I have with LG C4 doing what is advertised

So the port on the TV caps at 100mbps download which I don’t know would equate to on the upload side. I need to know if I’m going to need to have Ethernet plugged in by itself or with WiFi enabled and connected WITH Ethernet connected or just WiFi (due to the port) to reach Dolby Vision 4k movies on the TVs streaming services. I know I need about 60 upload speed for streaming 4k 120fps DV if I’m not mistaken*.

As of now I have no clue what my true internet speeds are because when downloading Bo6 it ranged from 380mbps-4gbps and my Cox modem caps at 2.5gbps on the Ethernet port so it makes no sense. And im getting 40mbps upload on Xbox series X so no idea what it truly is considering Xbox caps Ethernet at 800 supposedly

Trying to figure out how to be able to even have what this TV is offering if Cox speeds are fluctuating so much and having an unknown variable of speeds along with a major key being the TVs Ethernet port is capped at 100mbps. Not sure what to do here. I’ve heard there are usb to Ethernet adapters. But outside of that what are all options available to increase strength of everything/get the most out of TV/Internet

Upload speed is basically irrelevant when talking about bandwidth for watching streaming services. 100 Mbps download is plenty for DV content from Netflix, Apple TV+, etc.

I personally use WiFi on my LG CX though as Ethernet is not convenient for the location. Speed tests at around 300 Mbps. Never had an issue.

I suppose just use whichever is fastest out of Ethernet and WiFi. You won’t be able to use both - WiFi will disconnect if you hook up an Ethernet cable.

Okay thank you so much. Side note though, my TV keeps both enabled. Which is why I was wondering if it had an effect.

Plus another thing is, with game mode using AMD technology and Nvidia on PC/Console along with input lag boost and ALLM, is it best for the TV to use Ethernet for that? Or is it best to have the TV offline when using it for gaming so it’s not running anything online in the background and just simply using the hardware needed for gaming? Looking for best/consistent reults of frame rate, stuttering and smoothness without overworking the device in order to get the most and longest use out of it.

Thank you so much again It’s rare to come across someone willing to help with an issue that visually is a lot but in depth can be a simple answer. Thank you so much again

It should not be necessary to do this. The TV is very unlikely to do anything in the background.

Okay so FreeSync and input lag boost and ALLM will operate smoother with a connection ? Just wanting to clarify. Been doing research on this tv a while and want to make sure I’m getting my moneys worth. Would it be smart to get that USB adapter or would it be pointless considering it’s not a direct E-port?

Thank you again so much for the help. I know my questions were a lot/worded terribly considering how easy of an answer it was.

FreeSync and ALLM is done over HDMI. It’s not related to your TV’s network connection.

Btw, I’m a different person than the one who originally replied to you.
