Samsung MU7000 - HDR ?
« on: June 18, 2018, 05:30:57 PM »
Hi,

Are these real HDR yet? ie 1,000 nits? Or still the Samsung HDR?
What about the 2018 NU range?

It feels that HDR TVs are still fairly expensive, even 2 years down the line. I remember buying my KU7000 and thinking that within 2 years, HDR will be far cheaper - but seems they haven't really budged

I bought a LG 4k OLED HDR last week and the quality is really something you need to see to believe.

Personally i have never seen a better TV. The blacks are pure black the colours are extremely rich and when you watch a nature scene where the sun comes up it feels 100% real.

I also use to be a samsung fanboy but think LG did a sterling job on this range.

Ok so the MU8000 is a proper 10 bit panel / HDR10 - And it's not badly priced @ R25,000.00 for 65"

I do agree with the OLED being better, but when you in what you pay, it's a little steep for me at this stage. I think I can get the 55" OLED at R20,000 - but a touch small. As soon as we're looking at 60" or 65", it's more than twice that. The QLED7F is R30,000 which - although the OLED is better - I'm unsure if it's R12,000 better.

Also lacks the One Connect I'd like

I bought the 50" MU7000 and my ps4 pro identified that there is an HDR tv connected.

My KU7000 does the same - but my understanding is it isn't full HDR. I think that is reserved for 8000 series and up - but I may be mistaken

Yes, like many TVs today it accepts the input, but it falls short in its ability to render the content. At the moment TVs that are capable of rendering HDR to a satisfactory degree are expensive, I don't see this changing any time soon, not until we start to see new display technologies come into the market. Edge-lit LCDs, even when they do meet the minimum peak brightness requirement, just aren't well suited to the task.

Ken - MU8000 is 10 bit and should do a fair job, right ?

Agreed...I decided that I'm happier paying R8k for a tv that doesn't meet the full requirements, than R20k for a tv that still doesn't meet the requirements

The only difference, as we discussed, between 10 bit and 8 bit is the number of levels that constitute the greyscale. Each video level in HDR corresponds to a real world level of brightness. Since the TV's peak output is below the lowest peak brightness of an HDR signal, the full 10 bits will not be made use of but rather tone mapped down.

Now depending on how the tone mapping has been implemented you may or may not still have banding. On the one hand, the reason why 10 and eventually 12 bit is needed for HDR is because of the higher the peak brightness, the more levels are needed to prevent banding (you can only tell the difference between adjacent levels beyond a certain brightness threshold). On the other, levels will have to be skipped in order to tone map down, depending on how much highlight detail they try to retain. The balance will determine whether banding will be an issue or not.

The impact of HDR doesn't come from the bit depth or the colour gamut, though they are a part of it - what sets HDR apart is the perceptually quantised "gamma" (PQ EOTF), in other words the way light is rendered on screen, in a fashion the mimics the way we see light at play in the real world. In order to render HDR effectively a TV needs a low, stable black floor alongside areas of high peak brightness.

Are you saying that 8 bit might not be a deal breaker, depending on how the TV manages it? That colour banding might not be an issue? Is there a test for this (some downloadable media)?

What Ultra HD compatible TV these days isn't 10-bit? It's standard. I'm just saying that being 10-bit says next to nothing about the HDR performance. You can use a 10 bit gradient pattern to test for banding.
