Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems HD621 Does it support 4K?

No idea. They certainly won't hit target brightness of 1000 nits and are unlikely to have rec2020 colour. And HDR is a mess of formats at the moment.

I'm going to wait a generation before replacing both my projector and TV to give time for things to shake out.

It is probably worth noting that unlike HDR10; Dolby Vision is a 12 bit format and not 10 bit. Dolby claims that those 12 bits are the equivalent of 14 bits.

Dolby Vision

@ Ronnie; I’m not sure about the LG OLED; but Panasonic claim that the DX900 is capable of 1000 nits brightness.

This currently is the maximum brightness that HDR content is being finished to; though potentially it could be brighter still in the future. The DX900 is not – AFAIK - Dolby Vision capable; so it would seem that the answer to your question would be to wait.

The conundrum as far as UHD/4K Television is concerned; is that OLED still produces the better blacks than any LED/LCD TV. But LED/LCD is capable of greater brightness than OLED; so which technology is the better one to exploit HDR is subject to debate.

@Mark and @Drongo

Many thanks for the information.......much appreciated

As regards OLED Brightness, I suspect that with the annual leaps being made with OLED Tech that it won't be long before the brightness issues are sorted out

I use a Phone, a Tablet and a TV, each with an OLED display.......and hopefully soon a computer.......and I think it is the future of display tech over the next 5-10 years......including replacing Projectors and Screens with "Foldable" OLED Screens!!

I have an LG 960v 65 ins 4K OLED having previously owned a Pioneer KURO and can say that the picture it produces is measurably better than that of the KURO. As far as the ability to produce 1000 nits is concerned whilst my present set is not able to do this the panels supplied to Panasonic are produced by LG so if they can reach this level shouldn't mine also be able to do this with a firmware adjustment? One can hold back on purchases awaiting the next imminent development but in the end you never buy anything as there will always be something better soon!
I'm not sure how much extra HDR and increased brightness will enhance what I currently have so for now I live in the present with my fabulous OLED

Very true.

For me, at this time, it's about ensuring that the standards settle so that I know what I'm buying won't be obsolete. My 1 year old 4K Samsung TV is already junk and my Sony 1000es, similarly, although both will display 4K sources with workarounds. So, for now, what I intend to do is use them for as long as I can while waiting for the HDR dust to settle...

And then I will jump in and start to climb the years ahead as we get closer and closer to displays that will deliver full UHD format. How many years will that take, I wonder?

I feel rather left behind. I'm still happily using my Pioneer PDP-5000EX.

Some of you youngsters might need to look that one up...

Don't worry Dominic, having been cutting edge on 1080p, I'm now also in the dark ages...

This report on LG's 2016 OLED line-up is worth reading.

However, I really want this future product

Surely you mean movies upscaled to 4K on your 4K native projector?

Native 4K Bluray movies have only just been released, and not worldwide yet.
Or do you mean 4K compressed low bit rate content streamed over the net?

Er no, there is nothing wrong in my video chain thanks .

The Cine 9 WAS the best CRT projector available.
Did you ever see a Cine 9 playing a reference quality DVD upscaled by a crystalio scaler to 1080P?
Or are you just assuming what you think the picture would look like?

I recall the Barco 812 had 12" tubes, so at 500 lumens had lots more light output than Cine9, but 2 issues were:
1, huge glass curvature making edge focus poor.
2, line quadrupled wasn't enough. you could still see scan lines.
So DVD upscaled would look far better on a Cine 9. Much sharper image with no visible scan lines.

My real point was that upscaled DVD looked impressive and cinematic on a decent CRT projector, but upscaled DVD looks poor on a modern digital projector.
Also, in a blacked out room, the blacks/contrast ratio/dynamic range and the resulting image depth on the Cine 9 CRT I used to own, still has not been bettered by modern digital projectors such as the JVC, and Sony. They cant stitch the light off completely when black is required in an image. They rely on double iris etc.

I have owned several of the JVC's released over the last 5 years. I only swapped to Sony as it has greater light output more suitable for a large screen.

Anyway back to the topic, a HD621 would need HDMI 1.4 to support 4K at 30Hz, and HDMI 2.0 to support 4K at 60Hz.

The new flagship LG Ultra HD 4K OLED TV is the G6.
The G6 supports High Dynamic Range (HDR), more specifically Dolby Vision, and it has a colour space claimed to be 99% of DCI-P3.
The 10-bit panel uses 10-bit processing, includes support for Rec.2020 and is brighter than previous generations of OLED, allowing the new model to be certified as a "Premium UHD display".
What that essentially means is that the G6 can produce over 500 nits of peak brightness.

To be awarded the Ultra HD Premium Logo a TV must be capable of:
a 3840 x 2160 resolution,
10-bit colour depth
a wider colour gamut of at least 90% of DCI-P3.

The certified TVs must also be able to accept the Rec.2020 signal-input interface.
Because LED TVs are brighter, and OLED TVs can deliver vastly superior black levels; a certified TV can either offer a combination of at least 1,000 nits peak brightness and less than 0.05 nits black level or, alternatively, more than 540 nits peak brightness and 0.0005 nits black level.

The content must support:
an image resolution of 3840 x 2160,
a minimum 10-bit colour depth,
Rec.2020 colour representation
high dynamic range.

The Ultra HD Alliance also recommends that mastering displays must be capable of a minimum of 100% of DCI-P3 and a peak brightness of 1,000 nits and a black level of less than 0.03 nits.

I have the same TV as you. The LG 960V 65".
Good news is the recent firmware update enables support for HDR.
Increased brightness cannot be implemented by a simple firmware update. It requires hardware changes.

But the 960v sure is bright! I had to turn it down from 60 to 40. So I would not say current OLED panels have any brightness issues, and competes well with LCDm yet have superior blacks.
