Picture flickering

[wellyz]

We've recently had the Ultimate Oomph bundle and while the broadband is good the TV service leaves a lot to be desired. We came from Sky Q and thought the Ultimate package works make up for the change...

However every channel has a constant flickering on it, it's so subtle but when the image isn't moving i.e news channels or scenery images there's a strobing/flickering effect.

I'm using the hdmi cable that came with the the 360 box and tried others with no joy, I've turned it off and unplugged hdmi for 15 mins also, no effect. I've switched between "automatic" and 4K resolution settings, no change. I've used all the picture modes on the TV even the low latency 'game' mode, still flickering.

The TV is an LG CX, the 360 is connected directly to it via hdmi. The Sky Q box was connected the same and picture was perfect. 

Any ideas on what else I can try before submitting a complaint?

Does the same problem happen on...

1: Live TV, 2: Recorded programmes, 3: OnDemand/streaming?

These 3 ways of watching TV are fed differently, but share the common video output - so might help narrow things down.

Hi Japitts,

Apologies, should have mentioned that this flickering/strobing is not present on any other input just the 360 box. I've moved the inputs around to other hdmi ports to rule out a faulty port on the TV to no avail.

It is present on recordings too.

So to clarify - are you saying this issue isn't present on streaming/OnDemand programmes? I only ask in order to establish whether all output from your 360 is affected (suggesting a possible HDMI issue) or whether only certain content is doing it?

A quick google search shows that picture flickering is common on the LG CX series, although mainly seen by gamers.

The following page shows how to troubleshoot your LG picture, hope it helps Troubleshooting-flickering-video-tv

Automatic and 4K are basically the same, it's still 2160p. Try to move it to 1080p and see if it's better.

It's not there on catchup.

I've got a PS4 and PS5 connected to the TV, I also use LGs webOS to stream Netflix, Prime video and YouTube, none of these flicker. This only happens when watching live content on the 360 box and did not happen when I was watching live TV on the Sky Q box a month ago before we switched to virgin.. so not an issue with the LG tv.

I've set the picture on the 360 box to 1080 and its still flickering, I've put it back to automatic for now.

Are there any other settings I can change to troubleshoot this?

So to clarify - OnDemand isn't affected but live TV & recordings are?

If so... any particular channels? HD/SD?
