That's a different TV.

For this money think about the Samsung UE55MU7000
With the tiny size of 4K pixels it's very, very difficult to notice dithering at typical TV viewing distances so from a practical perspective it doesn't matter one way or another.

I agree there are other more important factors when buying a TV, but a 10 bit panel seems to be the holy grail for many on here.
I have this in a 49" and it's a 10bit got it in currys 5 year warranty £649 picture is brilliant

Don't so why it matters if it's a 8 or 10 bit. Pretty sure this TV doesn't have local dimming

Yeah, there is some confusion over what is significant. That's not surprising when we're talking about a new technology that works in a different way.

That's all the more reason to point out what difference it makes.

We'll I guess it's mostly about getting a bit more tech for your money. But in practical terms the absence of dithering won't make much difference. For comparison, a TV in the XE93 range that does have local dimming would cost twice as much.

I understand but at this price point it doesn't matter what bit the panel is without local dimming imo. I do like this tv. Does a good job of upscaling.
Good tv but this was £670 (after £250 cash back offer) + a free tv wall mount in the black Friday sales @ TPS. Gutted i missed the deal, i was hoping the January sales would bring similar/better offers but such luck as yet.

Was that on here? Can't see it. Would have jumped on it at that price.

And Sony don't reveal what bit depth the panel is. Or have they?

Yeah. Unlike them to be fair. Re: Sony and panel specs. I mistook a community poster for a Sony employee saying it's definitely 10 bit. Spec sheet is typically vague about what the panel is capable of.

I've quoted two other sources which aren't the manufacturer.
Without local dimming does the brightness tend to change accross the whole screen depending on the general lightness/darkness of a scene as opposed to dimming the specific area where there is darkness? If so I think I observed this on a Sony 55" 8005 model I had. It's very distracting when viewing anything.
I have the KDL55W905 from 3-4 years back. Was one of the best full hd sets back them and still brilliant now. Dont know whether to take the plunge on 4k yet.....no sky q at mo so will just be 4k bluray and xbox

It's much like when they call a 720p TV as HD. It's all about marketing

Displayspecifications.com pretty much exists to get this stuff right. No marketing from them. And AVForums are spec obsessed pedants who know the difference between 10 bit and 8 + FRC 😁

Pretty much spot on, yeah.
We were told ours is 10 bit. It's the 8396. It was£749 in Currys five year warranty with Sony. We paid£680 as there was a voucher code. Not sure what the difference is in ours and this .
After having a 4K non-HDR LG with local dimming, (which developed a screen defect) and going to the Samsung 55MU7000, I'd live without the HDR to get the local dimming back to be quite honest.

I used to watch movies with completely back bars top and bottom, and now the MU7000 is very dark but shows a bit of light bleed on those bars.

Forget HDR for now and focus on local dimming if it's an option. HDR is nice but unless side by side, SDR is more than good enough for 90% of the population.

Thanks for confirming. I'm definitely staying away from sets without local dimming then. To make that Sony worse, the dimming was a split second behind the scene changes. Really bad.

For £870 it is still possible to get the 49xe9005 from Richersounds by price matching with Hughes + code jan75. (which does have the local dimming I believe)

Actually no. What your describing is advanced contrast enhancer or something like that. Where the backlight changes based on the scene. You can turn that off
