LG OLED55C8PTA

I have a 1000Mbps fibre connection and achieve good speedtest results on my PC and phones using ethernet (approx 800Mbps down) and Wifi (approx 600Mbps down)

But on this TV I am only getting about 90Mpbs on ethernet, and 75Mbps on Wifi.

I think the ethernet port is actually capped at 100Mbps, but surely I should be able to get faster download speeds on WIFI?

How are you testing the speeds?

TV Wifi is notoriously crappy, and yeah the LG TV only supports 100 Meg on the LAN.

My recommendation is that if you have any audio equipment beyond a basic set of speakers or the TV's built in speakers, use an external device like an Apple TV, nVidia Shield, Playstation or Xbox. Any of them will output better audio and have a much better streaming experience.

Anything I say is the ramblings of an ill informed, opinionated so-and-so, and not representative of any of my past, present or future employers, and is also probably best disregarded.

I don't know if there is a single TV out there yet with Gigabit Ethernet. 100Mbps FE is just standard. Likewise it's not uncommon to still find TV's with 1x1 WiFi

The simple reality is there is zero requirement for anything faster than 100Mbps and won't be for quite some time, so no point in over engineering stuff.

That and most TV apps are crap anyway. Always best to have external box imo which normally has full speed lan.

Edit : I have an LG oled TV 2019 version and use an ATV4K.

What do you need a Ethernet port that's faster than 100mbps for streaming for?

Are you actually experiencing issues with playing streamed media?

A lot of streaming doesn't use much bandwidth at all, so 100Mbps link is fine for most cases.

There isn’t any need for anything faster - streaming media is quite lightweight to the point I have not bothered to run Ethernet to my Apple TV (I will eventually however).

Typical current streaming rates for most services is 6Mb/s for HD, 13Mb/s for 4k, so exactly what do you need a TV GigE port for. Further most ARM based TVs will struggle to deal with rates much above those mentioned, so again your use case?

@GeoffisPure In respect of TV Ethernet speeds, several people here are saying “no need for more than 100Mbps when streaming - so what’s the use-case and problem?”

That used to be true and mainly still is - but not always these days. Anyway the OCD-me finds it disappointing to have 1Gbps Max Fibre and get less than 100Mbps on my TV, because the TV's performance is limited by the manufacturer.

Recently I found this video by UK-based TV guru, Vincent Teoh, where he discusses all this and demonstrates a work-around for getting higher Ethernet speeds on late-model LG and Sony TVs - using an Ethernet-USB adapter.

Maybe this approach is well-known and is often used but I wasn’t aware of it until recently.

I couldn’t find his recommended Cable Matters brand adapter here in NZ. It’s available via Amazon Oz - have ordered and it will be here in a week or two.

(Vincent Teoh is a former professional TV calibrator. He has many TV-related videos on YouTube under ‘HDTVTest’ - reviews, comparisons, settings, calibration etc. He’s excellent IMO.)

Sometimes I just sit and think. Other times I just sit.

As already mentioned, no troubles at all streaming 4k HDR10 Dolby Atmos content from my local NAS to Kodi on the TV.

Yes that can work (as many TV's like Sony and LG are just running Linux based OS with driver support built in) but it doesn't change the fact that there isn't a single scenario where it will offer any benefit. Not one.

I'm just not sure why anybody would waste money actually doing this when it's going to make zero difference.

So would you prefer that this wasn't bought to the attention of people interested in this thread, who like me didn't know about it? For $20 I'm more than happy to get the adapter for the fun of it. Not exactly breaking the bank.

Apart from that, in the linked video, Vincent Teoh says:

"Netflix for example doesn't go above 40Mbps but streaming movies from NAS or Plex, 4K HDR movies may contain peaks exceeding 100Mbps, which can lead to buffering. Furthermore, Sony's new Bravia Core streaming service recommends a minimum speed of 115Mbps for the highest quality - which is above the in-built ethernet port cap on Sony's own TVs".

If he's right, that is one scenario where there will be a benefit and is not zero difference.

If he's right, that is one scenario where there will be a benefit and is not zero difference.

Sony recommend a 115Mbps internet connection to use Bravia Core because their highest quality streaming profile (4K HDR at 60FPS) will deliver peak rates that hit 80Mbps. By recommending 115Mbps there is overhead on the internet connection to avoid buffering. The viewing experience on the TV isn't going to change regardless of whether the TV has a 100Mbps or Gigabit connection.

The fact a peak may exceed 100Mbps doesn't automatically mean that you'll see any streaming issues. If you've got say a 5 second snippit encoded over 100Mbps peak but the average bitrate over say the 1m period is well below 100Mbps (which is going to be the case - you may find a 1min average might be ~60Mbps then the actual buffer in the TV is well within it's capabilities and the 100Mbps Ethernet won't be a limitation.

@GeoffisPure

I received the adapter referred to above and have tested it. With Ethernet straight into the TV (LG C1), we were getting download speeds of 93Mbps using Netflix speed check.

With the adapter, now get 285.

Nice to see.

Given that the TV Ethernet is capped at 100, this may be a solution to your original query.

@eracode Can you advise whether other network functions work using this adapter? E.g. does the TV still show up on a smartphone as a device you can push YouTube to etc?

I have some UHD BluRay remuxes that constantly pause if trying to run over 100Mbps Ethernet. Despite many emphatically claiming there's no use case where a TV requires more than 100Mbps, that's simply not true.

I currently get good 5GHz wifi speed which gets around my issue, but I'd much rather have the TV cabled.
