Ha! So much for one or two rather arrogant people here on gz who rubbished me last year when I asked about a wifi problem with our smart TV - “never use wifi, too many issues, cable is the only way to go” etc (even though I had had made it clear that running a cable was physically impossible).

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

There is no need for Gigabit because you're never going to get streaming bitrates that get anywhere close to saturating 100Mbps.

I was curious about this, what sort of streaming would be getting up to that, I know NF is not a great example, but doesn't it go to 16?

Netflex 4K will use around 15Mbps - 25Mbps but remember this is bursty so could peak at double that.

Even incredibly high quality 4K video files played locally would not exceed 70Mbps and since they're streamed in the same way locally won't burst like online streaming content.

The fact a TV has 802.11ac also means very little without understanding what chipset they're using and whether it's 1x1, 2x2 or 3x3. I've seen references online to a number of smart TV's with 802.11ac that is only 1x1 which means at MCS8 it can only deliver real worth maximum throughput of around 90Mbps using a 40MHz channel.

Even if your TV has 2x2 MIMO if you're running at 20Mhz channels to improve your WiFi coverage (remember 20MHz rather than 40MHz delivers a -3dBm advantage which can be the difference between patch 5GHz and great 5GHz in many houses) you'll only get a connect rate of 144.4Mbps which means around 70Mbps real world throughput.

That's not a bad price, and it is interesting to see significant discounting so early in the release cycle.

It will be interesting to see if and when the B8 launches in NZ this year. It's due out in the US Summer, but last year the B8 only launched here specifically for the boxing day sales with only Harvey Norman and Noel Leeming carrying it.

"Dual-layer UHDBR discs (66GB capacity) will support a max bitrate of 108Mbps, while triple-layer discs (100GB) will allow for up to 128Mbps"

The vast majority of the time they are well under 100Mbps, but they an certainly burst higher than this. My 4K streaming files are direct remuxes, so have the same bitrate as the original disc.

Tried Dunkirk last night, and it would constantly pause at the same points in the movie every time on the LG with 100Mbps ethernet.

On Xbox One (with Gigabit) played smoothly.

Switched LG to 802.11ac wifi and played smoothly (UniFi AP reporting TV connected at 867Mbps).

I guess they are expecting that UHD Bluray will be via a Blu-ray player and not streamed. 100mps is plenty for any online streaming service.

Agreed. 99% of people will be unaffected, but on Geekzone that percentage is probably higher. I know several people on here rip their physical media to NAS, and they are also the ones most likely to use structured cabling as the default option.

A lot of those (myself included) will be streaming via a box with gigabit Ethernet though. e.g. AppleTV with Plex etc. So for a lot of people, network capabilities of the TV less important than it's panel quality.

I ran the speedtest app on a sony 9000F and it was clocking mid-400Mbps, same as my other 3 stream 5ghz devices - I'd guess the A8F running the same wifi chipset (since both are 2018 android platform sony's)

A1 here as previously posted.

I cant get my sony to see by synology NAS directly. Not even if I use the DS file app it refuses to connect even though the same app on my phone is rock solid.

So cant play 4k go pro files.

Even if I force direct play on plex server and client cant get more than 8-10Mbps supplied from NAS. (Cat6 gigabit everything). Any get an error suggesting the network is too slow.

Defeats the purpose of those 4k holiday snaps.

Work in progress though.

- ie need to place video files of various codec on usb and go from there.

TV not seeing the NAS directly is the frustrating thing.

Didnt have this problem with any of my other devices (W8, W10, Rasp pi, android phone. sonos etc)

Agreed there as well.

I use Emby (got fed up with Plex) and normally use the Xbox One app, but a UWP platform defect is preventing 3rd party apps from correctly outputting HDR at the moment. That leaves me with the LG WebOS Emby app instead until the Xbox issue is resolved.

EDIT: Speaking of using TV smart functions vs external box - I'm actually finding the LG WebOS to be pretty slick overall. The biggest problem is that the new Freeview On Demand interface and guide don't seem to support the pointer from the LG Magic Remote, but this might be fixed down the track (not a big deal for me as I use a Logitech Harmony anyway).

I have an A1 as well (love it) and both QNAP and Synology NAS. I only play via Plex so have not had this issue but are willing to test via pm if want.
