Just got our new OLED TV up and running properly with 4K HDR programmes on our Sky Q box, and I notice that there can be some ‘juddering’ in the picture - most noticeable when the camera has panned across a landscape or suchlike. My thinking is that this is not how it’s supposed to be and rather that it might be something to do with my broadband speed not being sufficient to support a smooth picture (especially given the multiplicity of devices we have connected to broadband).

We currently have Sky Superfast broadband. We could move to ‘fibre to house’ from Swish or Hey! - maybe BT, or simply upgrade our Sky to Sky Ultra Fast.

Any thoughts.
 
What speed you on ?
Usually see judder on fast moving things like sport.
Have you tried playing with the TV settings.
There will be YouTube videos out for optimal settings for most TV's
 
As above - something in the TV settings. I can't remember what though! Lots of advice on the net to change from the manufacturers settings to ones that are much better.
 
Is it a LG C2??
Juddering is a bit of a design feature. Following the ball in football or rugby is the worst.
Putting it in cinema mode is the best you can hope for.
 
As a bit of advice for anyone going to store to buy a TV.
When you look at the demo content;
1) Never be impressed with lots of black in the picture. It's an OLED they all do this. Look at how faithfully reds and greens are reproduced to judge.
2) If the demo is in slo-mo move along, this is not the set you are looking for.
3) Look at shadows and clouds. If you can see the detail eg. brickwork or windows in shadows or if clouds look like clouds rather than white fluff then this might be the set you are after.
4) Any manufacturer that is showing sport in their demo content is confident they have a set better than the competition.
5) Thin TV's are bendy TV's. People who care about how thin a TV is are fools soon parted from their money.
 
When it comes to download speeds and considering fibre to house you need to consider what network adaptors are in the receiving device.
If you have the original Sky ITB Q box it has a slower adaptor than the 2TB box and I think LG TVs are limited to 100mb.
Assuming you have a smart TV you can run speed test programmes on the TV. I have a 3 year old LED LG and it only receives at 60MB from my 200mb fibre to house.
Also if you are network cabled to the TV you need to have Cat 6 cable min to make use of the fibre to house.

If it is an a LG

It’s most noticeable where the picture is rapid panning or their is more rapid motion … like a herd of charging wildebeest…🙄

It is…well IIRC I’m pretty sure it is.

ETA…it’s a C1 and cinema mode seems to help. Though also looking at getting fibre to premises anyway.

Was watching a 1955 film on YouTube yesterday on an older Sony HD TV and then switched to watching it on our LG C1 OLED…and the judder with the LG was painful.

Did a bit more reading on-line and switched from using YouTube on SkyQ to YouTube on the TV…and the judder vanished - or at least was imperceptible. I never realised there are different versions of YouTube with (some?) TVs having versions designed specifically for them and that’s why the judder was smoothed out. That said not all YouTube content I watch has the judder I was experiencing so I can continue to use the more convenient Sky YouTube, switching to the TV if judder is bad. If only I’d known before.

BTW - the film was Guys and Dolls…with Brando, Sinatra, Jean Simmons 😍 and the Goldwyn Girls 😘. A cracking good classic MGM musical. Love em.
 
Nice troubleshooting win! Glad you fixed the judder issue by switching to the TV's YouTube app.

And Guys and Dolls is a classic! Great cast and the Goldwyn Girls are always a treat.
 
Like others, I doubt it's a broadband issue. While we were waiting for FTTH, we ran our broadband on a 4G SIM with speeds no better than about 11Mbps, and 4K iPlayer content (stuff like Blue Planet) was fine.

Surprising that you were getting 4K streaming with 11mbps. The accepted minimum for 4K is about 25mbps minimum as far as I know. Are you sure it wasn't auto downscaling the content?

We don't normally watch 4K stuff - we watch HD Freeview. This was a specific experiment to see how good UHD is, and indeed it did look amazing. Much better than standard 1080 HD. So I don't think it was downscaling.
