Best TV picture of 2023: LG G3, Samsung S95C, Panasonic MZ2000, Sony A95L..or something else?

Which TV will have the best picture quality in 2023? There is a lot of talk about the headline flagship sets from the consumer electronics arms of the OLED panel manufacturers, LG and Samsung, with Sony’s A95K QD-OLED successor yet to be announced, but the truth of the matter may just have been staring us in the face all along.

Let’s summarise what some of the biggest TV YouTubers and Audio-visual websites have to say before reaching a conclusion.

Best TVs of CES 2023 (Caleb Denison)
  • Samsung S90C / S95C has potential for greater colour brightness and luminance if pushed
  • LG G3 META Micro Lens Array improves brightness but not necessarily colour brightness because of the white subpixel however he found colours to be brighter perceptually
  • Panasonic MZ2000 processing and picture quality made it one of the best at CES 2023
  • MLA just focuses existing light better rather than increases light energy so doesn’t increase burn in risk
  • MLA peaks at 2100 nits so a ‘150% increase’ (2.5x original or 1.5x original?)
  • QD-OLED2 colour brightness is measurably purer since no white subpixel but perceptually MLA may appear little different
LG G3 is 70% brighter (Vincent Teoh)
  • LG Brightness Booster Max light control architecture (MLA) and light boosting algorithms increase brightness by up to 70% but just on 55, 65, 77 inch models (not 83)
S95C
  • Samsung puts Micro LED top of its range with, OLED bottom and Neo QLED in the middle.
  • S90/95C in 55, 65, 77 inch sizes
Measured first MLA
  • MLA is brighter across all window sizes from 1% to full screen white giving more depth and punch and brighter colours
  • Panasonic MZ2000 1500 nits (cd/m2) peak light output on a 10% window
  • Graph shows 50% brightness boost over previous year’s LZ2000 at 10% window size but reducing to just 20% brightness boost at 100% window size.
  • Though brighter MZ2000 clears image retention quicker than LZ2000
  • Some scenes look identical in brightness on old LZ2000 and new MZ2000
  • With ambient light blacks look less black and more pink on the new MZ2000
Panasonic MZ2000 MLA
  • MLA design uses 27 billion lenses to redirect out of the screen light previously reflected inwards
  • Brightness is 50% greater than last year’s model
  • MLA increases colour volume
  • “True to the film maker’s vision” slogan – even though film makers take into account typical end user equipment
QD-OLED 2nd generation
  • 30% brighter over 2022 QD-OLED due to higher intensity light and less internal absorption
  • Blacks will be truer than the greys of QD-OLED v1 due to optimisation of the top layers of the panel
CES 23 Best Tvs
  • LG MLA and Samsung QD-OLED2 are the main technologies impacting top end picture quality for 2023.
  • TCL Micro LED promises the best picture quality but is 5 years plus away
  • Panasonic MZ2000 with MLA is vote for best of show with a visible difference against last year’s model
  • Wireless HDMI is on the LG Signature OLED M model
LG G3 vs Samsung S95C matchup (FOMO)
  • G3 Micro Lens Array (MLA) will achieve the best full screen brightness
  • S95C QD-OLED has a brighter blue OLED material and a new anti reflective layer will reflect less light and so achieve truer blacks in a brighter room than its predecessor (OLED v1 also used by Sony A95K)
  • LG G2 issues were full screen brightness, uniformity (magenta tint) and colour accuracy
  • Samsung S95B issues were lifted blacks under ambient light, low bit rate content processing and bent panels
  • The competition will be about high APL brightness and lower luminance colour accuracy
LG MLA G3 vs Samsung 2023 QD-OLED | Really 2000 Nits? (Classy)
  • Marketing materials don’t specify the brightness window sizes
  • Panel may be capable of 2000 nits but the implementation in the models may be less
  • Forbes states QD-OLED v2 is 1500 nits at 10% and a 30% improvement over the previous year.
  • QD-OLED issues remain: colour fringing with coloured lines in bright scenes and near black smearing.
  • LG G3 1500 nits on 10% window and 2000 on 3%
  • Both Sony A95K (QD OLED with heat sync) and Samsung S95B (without heat sync) holds sustained brightness better though does not get so bright as LG G2.
  • Panel consistency and lack of pink tinting are the main advantages of QD-OLED over OLED.
G3 v S95C (Brian)
  • Samsung updates in 2022, presumably to keep the panel safe, meant the S95B no longer offered its original brightness by the end of the year
  • QD-OLED2 is trying to be brighter than MLA (2100 v 2000 nits)
  • LG Evo G2 panel had a pink tint uniformity issue and Samsung QD-OLED S95B panel had a software update trust issue
Second generation OLED (KG)
  • At CES 2023 the Samsung booth demonstrated QD-OLED v2 as being perceptibly brighter with even more saturated colours than 2022 QD-OLED.

RTINGS.com provides measurements for several popular TVs and top of the line LEDs measure and are perceived as much brighter and more impressive with bright full screen scenes than top of the line OLED TVs, whether WRGB OLED or QD-OLED.

For 10% peak and 100% sustained brightness respectively, RTINGS.com gives

  • OLEDs: LG G2 (evo) 450, 190; Sony A95K (QD-OLED) 410, 148; LG G1 (2021) 406, 161
  • Mini LEDs: Samsung QN95B 1,934, 569; Sony X95K 1223, 633;
  • Full Array Local Dimming: Sony X95H (2020) 1085, 625

So to summarise, the latest 2023 OLEDs are 30% to 50% brighter than last year for sub 10% white windows but for full screen white are perhaps just 20% brighter so for viewing in a daytime room or bright high APL scenes with, for example, sunshine, snow or sports both of the new OLED technologies, QD-OLED v2 and MLA (META), remain much less impactful than LED designs.

Micro LED achieves the holy grail of professional reference mastering monitor black and bright performance like the 31 inch Sony BVM-HX310 but is too expensive a technology for mass market consumer sets for now and several years to come, with lower energy consumption being one of the technical challenges needing to be overcome.

How Excel bins handle decimals when using FREQUENCY

How Excel bins handle decimals

Each bin defines the absolute maximum number the bin can contain. A bin of 10 will contain numbers up to 10 so 9 and 10 but not 10.1. In other words, the bin contents are less than or equal to (<=) the current bin and greater than (>) the previous bin.

In short a bin contains numbers up to and including the bin’s number but not a fraction over the bin’s number as shown in the examples above.

People usually give their age as rounded down and age limits operate in that way too so a 17.9 year old can’t vote in the UK. If we want to find the number of people aged say 15-18 we need to use the Excel ROUNDDOWN function to make sure someone who is 18.3 or 18.9 appears in a 15-18 bin defined as 18. The previous bin in this example would have to be 14 to capture 14 year olds but not 15 year olds.

How many people have spoken to the Queen, Elizabeth II

How many people did the Queen speak to?
How many people did the Queen speak to?

A quarter of a million people, or 0.3% of the population of the UK that is alive today, or one in three hundred people in the UK have actually spoken to the Queen.

That figure assumes she spoke to on average 23 new people at each of the 21,000 engagements she attended during her 70 year reign, an average age of her interlocutor of 35, an average lifespan of interlocutor of 75 years (it is 81 in the UK in 2022) and the vast majority of her interlocutors being UK inhabitants.

If we include the 307,000 people she sent a 100th birthday telegram to and the 927,000 couples she sent a 60th anniversary message to that brings the figure up to 2.6 million people in total (alive or dead) she has directly communicated with, though this is an overestimate since there will be overlap between these these cohorts.

Since the written communications were over a period of 70 years, and assuming an average age of the recipient of the written communications of 80, 200,000 could be assumed to still be living, making for up to half a million people in the UK in total who are alive now (2022) having received direct communication from the Queen.

If you have any other thoughts or figures on these estimates please leave a comment below.

Of course, the Queen’s influence was felt by many more people, including myself. Her devotion to duty with good humour and intelligence is just one of the legacies she will leave us with.

May you ever rest in peace Ma’am.

Plantuml Archimate diagram made with Planttext

If you don’t have the funds or inclination to pay for Vizio or Lucidchart here are a few tools for easily creating a variety of common diagrams, from flow charts to entity relationship (data structure), dependency, UML and presentation graphics. Some don’t require any drawing or layout skills whatsoever and allow you to produce clear professional looking diagrams quickly just by typing concise human readable text – no manual and time-consuming drawing, positioning, resizing, formatting and alignment of objects and connectors!

Archimate Diagram

Archimate is an internationally agreed standard, in the style of UML, that lets one describe pictorially all elements of Enterprise Architecture from motivation like drivers, goals and outcomes to business processes, data, applications, technology, strategy, capabilities, courses of action (like projects and programmes) and deliverables.

https://plantuml.com/archimate-diagram

All Plantuml diagrams can be constructed, shared and saved via

http://www.plantuml.com/plantuml

and

https://www.planttext.com

however since the URLs are so long (the URL encodes the script that describes the diagram) a URL shortener can be employed for easier sharing and embedding.

https://tinyurl.com/5d258ucc

Tip: change the real URL you land on using the shortened link above from the format

https://www.planttext.com/api/plantuml/png/{long string}

to this format

https://www.planttext.com?text={long string}

to be able to edit the diagram!

Note: if you change the diagram the URL of your edited diagram will also change, which means that you will need to change the diagram URL embedded in any documents that refer to it if you want them to reflect your edits. Of course, if you simply download and include the generated png file in your document you need to change the document whenever you revise the diagram too. The upside is that anyone can revise the diagram in future without having to recreate it from scratch and without needing any software – just internet access. One isn’t even dependent on a particular website since the ‘long string’ from http://www.plantuml.com/plantuml/uml will also work at https://www.planttext.com and one can even install one’s own diagram server:

Top Gun 2 (Maverick): Top Gun for Grown Ups

TG2: Top Gun for grown ups

Top Gun: Maverick wasn’t what I was expecting but was none the less enjoyable for that.

We know from the now 2 year old ‘making of’ trailers how much effort went into capturing the real life flying scenes but for me the visual spectacle didn’t translate to the big screen significantly more than the equivalent scenes from the original.

What did unexpectedly move me was the maturity of the story elements around the characters. Top Gun was almost a coming of age movie about internal conflicts but TG2, rather like Trainspotting 2 finds new material in the things that matter to its now older and somewhat wiser protagonists. Managing relationships in a new mindset with less bravado but more recognition and acceptance of oneself and others and knowing that sometimes we just don’t know.

Yes, the plot may be ridiculous and we can see the manipulations coming but nevertheless I found myself welling up at those moments of mass audience acknowledgement of some of life’s truths and values. Hard work, honesty, tact, camaraderie, courage, compromise, humbleness, mutual respect and understanding.

We may not know the answers but perhaps the message is that sometimes just trusting our instincts is more valuable than thinking, conveyed in the somewhat hackneyed but pithy line:

Don’t think.

Just do.

Like a son, TG2 may inherit some of its forebear’s characteristics but is an entity of its own. Enjoy the ride.

Everything wrong with the Samsung S95B QD-OLED TV

Samsung S95B frustrations?

This article is now available as a video!

There are a lot of glowing reviews of the latest flagship TV from Samsung, the S95B. Samsung Display’s new and much awaited QD-OLED technology brings extra brightness and colour volume to the inky blacks of regular W-OLED technology, but if you scour the TV reviewer videos, AV websites and shopper reviews you’ll find a surprising number of less than positive aspects reported too.

I’ve summarised those I’ve found so far below but leave a comment if there’s anything I’ve missed.

Starting with a thread of 15 issues based on this TV YouTuber’s findings:

I’ve lumped these problems, plus those from other sources, into a set of categories:

Physical e.g. size

Only comes in 55 and 65 inch sizes: https://www.samsung.com/uk/tvs/oled-tv/s95b-55-inch-oled-4k-smart-tv-qe55s95batxxu/

11/ Panel can be bent in shipping: https://www.amazon.com/SAMSUNG-55-Inch-Quantum-Built-QN55S95BAFXZA/product-reviews/B09VHBXY63

15/ Bright lights near the screen make blacks grayish

8/ Cleaning with water can leave spots, though this might help: https://lifehacks.stackexchange.com/questions/17639/how-to-remove-water-stains-from-tv

User Interface e.g. OS and remote

13/ Tizen OS is laggy: https://en.m.wikipedia.org/wiki/Tizen

“an uninspiring smart platform”: https://www.reviewed.com/televisions/content/samsung-s95b-oled-tv-review

Small remote with no back-light: https://www.bestbuy.com/site/reviews/samsung-55-class-s95b-oled-4k-smart-tizen-tv/6502216

Picture Processing e.g. black crush, blown highlights, colour accuracy, upscaling, motion handling, HDR modes.

9/ Out of the box, filmmaker mode is brighter than movie mode and shadow details are too dark: https://www.samsung.com/us/support/answer/ANS00079295/

10/ In some modes eotf is pushed too bright affecting mid tones

Inaccurate or oversaturated colour and luminance:

https://www.avsforum.com/threads/samsung-4k-s95b-qd-oled-owners-thread-no-price-talk.3240720/post-61604628

1/ Colour fringing with dark objects against a light background: https://en.m.wikipedia.org/wiki/Chromatic_aberration

3/ Shadow details can be crushed or overly bright: https://www.howtogeek.com/728797/what-is-black-crush-on-a-display/

4/ Dark scenes can trigger dimming (tho not the only OLED to do this)

2/ Low bit rate content shows aliasing and smoothing artefacts: https://en.m.wikipedia.org/wiki/Spatial_anti-aliasing

14/ Smooth gradation can show posterization: https://en.m.wikipedia.org/wiki/Posterization

5/ Motion can show ghost trails

12/ Motion interpolation introduces artefacts: https://en.m.wikipedia.org/wiki/Motion_interpolation

No Dolby Vision HDR mode: https://www.reviewed.com/televisions/content/samsung-s95b-oled-tv-review

Quality Control e.g. bugs

Screen cuts off the edge of images: https://www.amazon.com/SAMSUNG-55-Inch-Quantum-Built-QN55S95BAFXZA/product-reviews/B09VHBXY63

6/ Auto colour gamut and auto input switching are unreliable: https://en.m.wikipedia.org/wiki/Gamut

7/ Picture settings reset unexpectedly 

Longevity – OLED tech is based on organic materials which wear out

Brightness – QD OLEDs can get bright but are nevertheless still much less bright than some LEDs

It’s the brightest OLED we’ve tested to date but S95B doesn’t get as bright as some of the brightest LCD/LED TVs:

https://www.reviewed.com/televisions/content/samsung-s95b-oled-tv-review

Value – price to performance is not the best

Cheaper LEDs like the Sony X95K and its kin have as many strengths and come in larger screen sizes

Finally, trust your eyes – look at some footage of a real life scene and see which TV looks more realistic and involving. And if the measurements of the TV you prefer are worse than some other TV then the measurements are measuring the wrong things – things that don’t necessarily reflect our perception.

And beware the shills and bots lurking in the comments – you need look no further than those in my last video to see the kind of unsubstantiated hype they come out with!
