The KS series were fairly popular during its launch , primarily because people were looking at wrong numbers .



It was tested to reach 1400 nits + on test patterns but the picture fall flat quickly after , due to the TV's inability to hold the same level of luminance unlike the rivals , Sony's Z9D and X930E which can sustain the brightness level for a long time .


Its actual brightness level fall in the range of 400-500 nits ( which is roughly the same as GX800 ).

If you compare with the GX800 , the Panasonic TV has an advantage of dynamic tone mapping , more precise color reproduction despite not packing the quantum dots filters .
Samsung is still having problems to accurately control the large amount of colors from quantum dots layers .

Dolby Vision is also a bonus .

Considering the list of features , the GX800 is more versatile than the KS7000 .


Overall I would say GX800 is an improvement from the KS7000 , however small the improvement is .
IMHO probably not worth spending money just for the tiny upgrades but it is an improvement regardless , on the perspective of Picture Quality .

Watch out for those FZ950K , but I think you've just missed the 11.11 sales where they have gotten insane discount from it.

55" can still be found under $6k ( dropped below $5k during the 11.11 ) . Maybe they will have another wave of crazy sales in the upcoming 12.12.

The sales are gone . They were some of the cheapest 55" OLED ever found in Malaysia .


A few guys picked up the 55" for just under $5k last month and have been showing me their lovely tv since then .

Grats to all those who've scored another great OLED TV.

I assume you are talking about the newer HDMI 2.1 ports .
HDMI 2.1 ports are currently only available for premium ( translation = very expensive ) Samsung & LG TV models .


This specific TV model has a refresh rate of 60hz , it doesn't matter what they put on their spec sheets .
TV brands make up a lot of crap just to tempt buyers into their marketing gimmicks .

Except Plasma has already gone obsolete and completely replaced by OLEDs .
( my trusty kuro is still alive and kicking and has a special place in my heart )

It is one of the most basic TV models from the brand . Comparing it with Plasma is not exactly reasonable .
For most people who are looking for TV in this price range , beside the promise of being a 4k TV you really should not be expecting anything .
Anything more is considered a bonus .

In some cases , those RGBW budget models can't even deliver true 4K resolution .


With that being said , OP's problems most likely have something to do with the settings .

For certain TVs , the brightness setting actually does not adjust the luminance . Instead it changes the gamma settings which you really shouldn't be doing without proper test patterns and calibrating experiences .
Try changing the viewing mode to " Cinema " and adjust the " Backlight " settings instead of brightness .

Without actually attending to his TV , I can't really do anything because the description is too vague .


This is why we need to look for brands which have better out of the box settings and calibrate our displays .
Although in this case , the calibrating tools and services are most likely going to cost more than the TV itself ...

I really doubt it .

These Panasonic Android TVs originate from the same GX655 series which Panasonic had launched specifically for India , their budget market several months ago .


It doesn't really matter if they put HDR10 or Dolby Vision in the spec list , it simply cannot deliver the effects .

GX880 is basically the larger screen size of the GX800 models in our market .

This post has been edited by Convael: Jan 5 2020, 08:47 PM

It doesn't , none of the GX800 variant has local dimming .
What you are noticing has nothing to do with local dimming but the backlight system of the TV .

This is an edge-lit TV , which tend to demonstrate many of the flaws you mentioned above in a dim/dark viewing room . Also the fact that it has an IPS screen (which means it has a poor contrast ) doesn't help either .


IPS TV are typically recommended in a decently lit room because human eyes can hardly notice the changes on black level when there are ambient light sources around .


There are several new Full Array Local Dimming TV models landing in Malaysia this year , ranging from the very anticipated Sony X90H to Samsung's Q80T and Q95T , all models will be available from size 55 " and above for the first time in MY.
I predict there will be a significant price drop compare to last year .


They are both mid-range TV , except Samsung likes to overhype on their Quantum Dots displays when they can barely utilize its benefits .


The GX800 is compatible with Dolby Vision though so that is a plus .

The 49" Q60R is also kind of crappy since it was downgraded to 60 hz .

No , there is no fact here . The TV just doesn't has local dimming .

I think you are confused , because you see a few " columns " that lights up you are thinking it is local dimming because you have been reading some of those FALD TV has "zones " .
These are completely different things .


It is similar to what Hisense called their TV having 2 zones , 6 zones .
Those are not local dimming system , they are software based algorithm used to restrict the APL and they are not effective at all .
They can give them whatever name they have , commonly known as global dimming , frame dimming , etc etc . They don't improve picture quality.


Localized dimming system , need to do 2 things .

First , is to dim the black levels to improve contrast and thus also improving picture quality .

Second , to boost the Highlight of brighter portion of objects objects to improve the Dynamic Range of the picture .

A Full Array Local Dimming can do both , an Edge-lit based Local dimming TV can only brighten the picture .
We have had great Edge-lit local dimming TV before , like the Samsung NU8000 which can boost brightness up to almost 1000 cd/m . GX800 does neither of this .

Also GX800 models have an edge-lit based backlight system ( not to be confused with local dimming ) , even if it has local dimming it wouldn't show up in "zones " .
Remember , the models shipped in our country is the IPS variant , it is different than most of the GX800 reviews you read from the internet.

TV brands are free to list whatever they want on the specs , but a TV with local dimming system will not peak at 290 nits .

Just like whatever names Hisense and many others brands want to call their frame dimming is .

Not really , not every LED TV has light bleeds , mostly only the edge-lit TV models and IPS TVs due to the imperfect shapes of subpixels .

At the very least , learn to differentiate the Pros and Cons of IPS &VA TV first before you start giving advice .
What's wrong with being technical in a techie forum ? If you just want to trash talk your way to the end , there is the /k section.


Another assumption from you .

The GX800 is already at baseline 300 nits . If we go with your logics , the GX740 has to be even dimmer than every other modern TV , including those beginners 4K models from other brands .
You need to stop reading into whatever terms the TV brands are throwing at you . At this point you are only spreading wrong information .




True , but there is a huge difference between local dimming or simply calling it a dimming system .


First of all , there is no story . I have spent roughly 2 hours with the TV beside NU8000 , which an edge-lit local dimming TV .
It doesn't dim nor boost , it does nothing , absolutely no changes on the black levels and brightness .

Localized Dimming system is specific hardware that is implemented on the LED array , something alike a curtain .
If there are any existence of local dimming , there would be at least improvement on the numbers of black levels or brightness .

The last model I have inspected indicate this TV peaks at 300 ~ 400 nits , which is a common standard for modern UHD TV.




This is one of the most pretentious and wrong thing I have heard in this forum for a while .

Local Dimming is the system that is responsible for brightness output of the screen . They are closed related . How is that a different story ?
And of course we are going to talk about HDR , why do you even need a local dimming system for non HDR stuff ? Did you even hear yourself ?

You clearly have not even seen a FALD TV , nor you have any idea what is a local dimming system if you think its only function is to dim down the backlights .
You are only reading it by the name , which is limited by your understanding of TV's backlight system.



Again , for the 10th millions time , there is a HUGE difference between the hardware based (which is also called Local Dimming ) and software based dimming system .
The only one twisting the facts here is you because you are too ignorant and stubborn to learn .

Also , I am not responsible to give you a lecture since you are too lazy to even google .


People have already reviewed this TV and all the numbers are out there , the result is clear . It isn't even up for debate .

Even if we are to assume this TV has local dimming , it does nothing to improve on the picture quality . If that is the case , what's the point ? Why are you being obsessed with benefits that don't even exist ?

Also the model Vincent reviewed is different than yours . If you watch his videos then you should remember the keyword " pseudo local dimming " . That is like a more polite way to say the dimming system is completely sh*t.
Last but not least , I assume you are capable of understand what does the word " BARELY " means , right ?


To summarize , I do think there is some sort of dimming system within the GX800 models but they are definitely not the hardware based LED Array zones we are used to be seeing on the market.
It is more identical to the same thing many brands are calling Global Dimming / Micro dimming / Frame Dimming , a software based dimming algorithm on their entry level TV .

I have already been threaten by Samsung PR several times for exposing their " frame dimming " tricks .

The other day some Philips TV retailers weren't too happy with me calling their global dimming shit too .

You would be surprised how many TV sellers are watching this forum .

If we go by context , the " Super Bright Panel Plus " is suggesting the TV screen is brighter .
It is highly misleading because it indicates this TV has a screen with higher brightness value but that clearly isn't the case .

Panasonic is known for making up numbers , for example look at what sort of numbers they are putting in the motion column , a whooping 1300 , 1600 and 3000 "backlight" motion rate .
You would be silly to think the TV can actually go that high . Apparently to Panasonic , whatever they are calling motion rate isn't the same as other brands .



All of the current gen of 4k TV can achieve a value of 300 - 400 nits , which is the modern standard of the last 5 years .
It cannot , will not and shouldn't be any lower unless you've decided to calibrate your TV that way .


According to the booksheet specs of Panasonic , the Panel used for GX 740 can achieve a peak brightness of 400 +- nits , while the Super bright Panel plus used for GX 800 is capable of 500 cd/m2 peak brightness .
I believe MY's GX800 is using the same AMVA3 LCD screen found on the likes of Sony's X85 series . But for whatever reason , Panasonic has decided to restrict both TV to the more standard baseline of 300 Nits , bright panel plus or not .

Again , I am unable to locate a GX740 for any test view purpose so I cannot verify this .

I can't speak for GX740 but GX800 was one of the most accurate LCD TV I have ever inspected in recent years , which translate into very natural and comfortable viewing experience especially with the support of both Dolby Vision and HDR10 +.
And the additional features like dynamic tone mapping which is absence in many of the mid-range TV is a sweet bonus.

I am 100% sure youtube does not support any version of Dolby Vision , only HDR10 and HLG .

This post has been edited by Convael: Oct 4 2020, 03:26 PM

These so called " zones " can also happen in pre-programming algorithm within the software dimming , 1-6 or 6-12 zones .

That is not a local dimming system because even SDR TV can do that .

All it has to do is turn off the half or quarter of the LED ARRAY in the backlight , it doesn't actually control its backlight to the same manner as NU8000 or even the new X90H .
To add to the argument , GX800 has a typical brightness of 300 cd/m2 . And if the local dimming system is effective , it will be way higher than 300 cd/m2 .

This suggest GX800 either has an inactive Local Dimming system or has none . I haven't actually crack open a GX800 to check .

At the end of the day we care about the result .

Since either of the answer lead to the same result - it doesn't nearly improve the Picture Quality like a FALD TV like X90H do , it is pointless to argue about its existence .

There is no argument here really , I did not come to that verdict out of speculation.

We know that the most important factor to consider for TV's picture quality is the contrast rating , which is the measurement from the brightest part to the darkest part of the screen .
The whole purpose of local dimming was to enhance these aspects . Therefore making the brightest part brighter , darkest part darker , directly contribute to the increase of contrast numbers .


There are 2 types of local dimming system in the TV market right now :

The FALD . In a typical fashion , FALD is able to divide the whole backlight system into multiple zones of lights , darkening selected zones while boost white of the brighter portion.
Which is also why , TV with more zones is usually has much higher contrast ratio when Local Dimming is on .

Obviously the GX800 does not fall into this category so we will stop talking about this .



Moving on , we have the second type of local dimming which is edge-lit , like what you saw on NU8000 .



Due to its nature of being edge-lit , these TV can only improve on boosting the brightness because it lacks the more advance zones to shelter the backlight completely [ due to it lighting up the pixels from the edge of the screen].
The cons being , when it lights up the screen it usually brighten up the entire column , hence doesn't improve the dynamic range as well as the FALD .

You are correct in a sense that we already have a great example of it which is the NU8000 .
Being an edge-lit local dimming TV , it is able to shoot past 800 nits . That is a whole lot of headroom for HDR compare to GX800 .


If we go by your logic , the GX800 should belong to this category assuming it does really has a local dimming .

Now back to the question , where is the benefit of having this type of local dimming system ?
The sole advantage of being an edge-lit L.D is you still get a pretty good boost on the luminance like the NU8000.

Merely having a peak brightness of 300 cd/m2 , the sole benefit of edge-lit Local Dimming is almost non-existent . It is definitely not an FALD therefore the enhancement of having deeper black levels have vanished as well .
It doesn't boost its white or black levels , therefore bringing nothing on the table on the perspective of picture quality .

To be fair the TV is still fairly decent for having WCG and good accuracy OOTB but those benefits has nothing to do with its local dimming system .

Panasonic has released its 2021 Catalogs for TV .



From Jx700 , Jx800 to the flagship OLED JZ1000 and JZ2000 , the latter which is dubbed " Master HDR OLED " , aim to provide the most complete and premium visual experience on TV .

The flagship series will ship with all HDMI 2.1 features , with 2 x HDMI 2.1 ports .
The LCD models , namely the JX700 and JX800 series , will be running on Android TV while the OLEDs will retain Panasonic's MyHomeScreen OS.

At the same time these TVs will also be supporting all forms of Major HDR format from Dolby Vision , HDR10 + [& its open sources variant] , HLG and the less prominent HDR10 .


On the other hand , this is the first time Panasonic MY has ever decided to release their " Master " OLED series in Malaysia , featuring a dedicated heatsink and brighter OLED panel .
Panasonic's 2000 series are rated as the brightest among the OLED TVs . You may finally obtain the best Picture Quality on commercial display money can buy .


It is currently unknown if Panasonic is still planning to bring in the more affordable , watered down 60 hz OLED models into MY before the end of 2021 .
While LG's affordable OLED - the A1 series is still on track to arrive in the country within the next few months .

You have to understand the fundamental of TV OS .
They are NOT LIKE PC Windows , not meant to be used as a browser or flawless playback because of the very limited power of the CPU on board.



The TV system on chip [SOC] often has to perform so many tasks simultaneously from picture processing, handling signal inputs and outputs , power budgets and so on.
Anymore tasks you are assigning the TV to do is going to stress it to its knees .

This is particularly true if you are buying entry level models since those are using even weaker chipset .
And no biase here , this apply for all of the TV brands .


We have got some budget TV which seems to run pretty smoothly , unfortunately just looking at the screen makes me puke .
These TV disable any sort of picture processing hence they are more prone to a bunch of pixel artifacts , motion blur issues .


You may invest in high end flagship TV where they often come with a separate SOC and VPU.

Or better yet , get a good TV box , smart TV OS is way overrated .

OEM is by TCL . But Panasonic is the one who finetune and tweak it .
It just goes to show 1 thing , when it comes to accuracy (hence , PQ ) no one has surpass Panasonic and their can do it on any platform given the resources .


The only reason they tripped last year , was due to the limitation of the crappy TV CPU .


Otherwise , Panasonic TV is always a pleasure to watch .

I probably have mentioned this before , watching anything on the these Panasonic OLED is like looking at a piece of smooth and silky fabric .
It is eye-wateringly beautiful .

I just wish they get rid of the crappy " myhomescreen " UI . It has been pulling their legs for so very long .

Currently I still have a C7 , a C8 and a CX . All of them have over a thousand of hours watched .
I also have an old A9F I bought from Sony at really cheap price which I am using for color workflow .


Obviously I am a TV dork , so I don't just watch TVs .
I run patterns on them , I tweak them over and over to find my settings and even subbed to most of the major streaming platforms just to stream things on them .
It is just a hobby of mine .

I also carry a USB (and a Murideo 6G , can't afford the 7th and 8th yet ) consist of excerpts of movies that I have collected over the years .
I normally bring them everywhere with me to run things on TV screens I see and fortunately most TV merchant and my friends seem to be tolerant with me so far .


Unsurprisingly the TVs I owned are mostly from LG and Sony . I am still looking to get a 2000 series but the 2000 last year was a botched job .

Panasonic OLED has impeccable PQ but at the end of the day , that OS is just terrible .

Eg , one of the previous OS updates is removing the support of PLEX , not a big deal if you have a BOX which you should by now .
But if you are don't , you are basically screwed .
