Got an LG OLED tv (65” E6), have a question about Ultra HD 4K feed from Netflix. Basically if I watch a Dolby Vision programme from Netflix the TV detects this and puts a Dolby Vision symbol in the top right hand corner of the screen. It then gives me choices of Dolby Vision picture modes. However if I chose a Ultra HD 4K feed from Netflix the TV doesn’t seem to detect this and remains in standard mode.

To support this if I swap to my new Apple TV source (latest gen) the TV detects this and puts a little HDR symbol in the top right hand of the screen and gives me options on HDR picture modes (HDR standard, HDR vivid etc).

So my question is should the TV be detecting the Ultra HD feed from Netflix and switching to HDR? Anyone else got an LG and Netflix who could confirm?

Thanks.

Ultra HD means it's just 4k, not HDR content.

It'll only play in HDR if it has the Dolby Vision symbol.

This.

Your Apple TV shouldn't be sending an HDR/DV flag on non-HDR material.
Are you comparing the same program with both feeds?

The apple will only play HDR content that shows with the Dolby Vision symbol on the LG, but because it can't do DV like the LG, it displays as HDR 10, hence the HDR options popping up on the apple.

4k Ultra HD has no HDR content though. Both devices will just play it at a 4k resolution.

Thanks everyone. Think I’m confusing myself, a lot! I guess the TV is setting itself to HDR mode when I choose the Apple TV input because the HDMI input has Ultra HD Deep Colour set. This was set automatically on this HDMI port when the Apple TV set itself up. Is there anyway I can see what it is actually playing at when I play a programme/film from the Apple TV?

What is odd is if I go to Amazon Prime on the TV, that will also switch to HDR mode when I play an Ultra HD programme, but not if I play standard. Yet Netflix doesn’t seem to do this for Ultra HD, it just remains in standard mode and just switches when I play Dolby Vision from Netflix.

Sorry if I am being thick confused

The info button should tell you?

HDR 10 is effectively a subset of Dolby vision.

Try turning off HDMI deep colour on that particular input and see if it still flags HDR on non-HDR material from the Apple TV.

HDMI Deep colour has little to do with UHD 4K or HDR/DV.

Deep colour would need to be enabled on the LG for the input the Apple 4k is connected to. This way, anything that is HDR enabled will be displayed. If it's not enabled, the LG won't do HDR via that input. Make sure you set the colour gamut to wide on the LG for the full effect.

Although I don't own an Apple TV, I do have an LG OLED. I presume you're using the Netflix app on the LG to see the DV symbol? If so, when you see a Dolby Vision symbol, it will play it back in Dolby Vision HDR. A DV pop up appears in the top right hand corner. If you use the Amazon app on the LG with HDR content, a HDR pop up appears in the top right hand corner as Amazon doesn't do Dolby Vision, but HDR 10. The LG can decode both.

When you use the Apple TV, any program that had the DV symbol on Netflix on your LG, should just have a normal HDR symbol next to it. That's because as far as I'm aware, the Apple does not support DV. The LG therefore uses HDR 10 and the HDR pop up will appear.

If the program is just 4k Ultra HD, it does not have any HDR encoded into it. No matter if you play it via the LG or the Apple, there is no HDR to decode so you should not get a pop up. It's just 4k resolution, for which you'll get no pop ups.

If you are getting a HDR pop up on the LG by playing content on the Apple that has no HDR encoded, I'm at a bit of a loss to explain it.

If you have an example of any material that seems to be causing a problem, let me know and I'll check it out when I'm able.

Good luck

Just to add, Amazons HDR content on the LG tv app is much harder to find then on Netflix.

On Netflix if it's HDR enabled, you'll see the DV symbol on the very first page. Easy peasy.

All Amazon will say is 4k Ultra HD. They don't make it obvious. Some 4k UHD content will be HDR, some won't be. You need to go down a level or 2 to see if it's HDR.

I'm assuming this is the source of the confusion as it looks like you are choosing 4k Ultra HD on Amazon and it's coincidentally HDR, but not all of it is. For example, Bosch is HDR but you can't tell at first glance as it says 4k Ultra HD.

From digitaltrends review:

The primary issue is that the Apple TV, when connected to an HDR-capable television, is going to force that HDR TV into HDR mode all the time. As we learned from speaking with Chris Heinonen, a colleague who currently writes for The Wirecutter and Reference Home Theater, this can present some problems when playing SDR (standard dynamic range – AKA most of the stuff you watch right now) content.

It's the Apple hardware causing the issue not the TV.

Thanks, I think this explanation of how it should work and Bighop's response pretty much explains what I'm seeing in that case. So when I run from Apple TV it forces the LG into HDR mode all the time which is what is confusing me.

Appreciate all the replies.
