bro do you own this tv? how is the performance of this tv and it is still need android box such as himedia to give high performance for 4k movies?

1) GX800 is Smart TV therefore, apps is limited to their own. If you're happy with just Netflix, Youtube and Amazon Prime videos, then you dont need Android box. If you're looking into having tons of apps and games, u need to buy a separate android box. Do you use AV receiver?

2) The tv has 5 energy star rating.

3) I u ask about performance, all TV brands in their same range should perform the same. It comes to whether you like smart tv or android tv, the HDMI spec and sound system. Picture quality are all very subjective. we can spend a lifetime arguing about picture quality and in the end, nobody wins. Its best to go to electronic store and see it for yourself. thats what i would do. If you want to get down to the technical part, then you need to ask a specific question like if this tv good for gaming/movies, IPS or VA is better, OLED and QLED, dolby vision/atmos etc then maybe somebody here can help. whats your budget though?

Soon the GX800 will be replaced by HX800. Its worth the wait I hope.

1) Actually not yet buy the tv first plan to buy Sharp BK1X but somehow i found this panasonic tv got this dolby vision/atmos and also got usb 3.0?????

3) When you bought this tv, how many years in the warranty and support? till now did you got any problem using tv in term any broken parts? How many inch is this tv you bought?

1) Dolby Vision definitely improves picture quality but only if you watch Blu-Ray disc, Netflix and Amazon prime. If you download your movies, then you won't get Dolby Vision. As for Atmos, to fully experience it, you need to connect your TV to a soundbar or AV receiver that supports it. The TV speaker wont be enough.

3) Its 2 year warranty i think. ive been using it for just over 2 weeks. No problem with the TV so far but im bothered by the uneven backlight or light leaks. But this can varies between devices. if its gets worse, ill call up panasonic if they can do anything about it. My philips last time has the same problem, they came by my house with 1-1 replacement

1) may i know why u said when i downlaod movies cannot get dolby vision?

3) oooh u recently bought this tv may I know what is the mean of "uneven backlight or light leaks" can you give the screenshot

1) if im not mistaken, Dolby Vision movies are copy protected and no one has been able to crack from either netflix or blu-ray. thats why you dont see dolby vision movies in torrents. there are lots of HDR movies though.

2) Below is just a sample. not mine. Some manufacturers consider certain level of light bleed/leaks acceptable because LED TV is not meant to be watched in the dark. You can actually truly enjoy this TV in normal lighting condition. So after you buy this TV, keeps the lights on, keep the windows open, and enjoy

hahah noted

what is your tv inch?

I have the 55 inch. U might want to consider gx740. It has the same specs but has a different LCD panel and it's wayy cheaper. I don't think it matters too much to normal consumers. Under normal viewing condition, they should be about the same.

bro what different between gx740 and gx800 and what u mean for normal consumer???????????/

Haha didnt mean to offend you. By normal consumer I meant some consumer they are not bothered much by the technical aspect of a TV as long as the TV is good enough to watch under normal circumstances.

But if you have to ask what's the difference, the panel on the GX800 is brighter than the GX740. In the official spec from the website, the GX800 has Super Bright Panel Plus whereas GX740 has Super Bright Panel (not plus).

This simply mean the GX800 has brighter panel and produce great picture quality even under bright lit room. But not to say the GX740 is terrible, just the GX800 performs better. I hope this helps

Dolby Vision is separately on HEVC 2 layer and currently no DoVi support for matroska container yet. That the reason why only have HDR but no Dolby Vision copy of downloadable movies as no one able to remux it yet.

The only have is full ISO image in MP4 format, this is freaking big and only working on certain Dolby Vision support TV.

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 .

Then you can put a lawsuit to Panasonic. Haha! lol... ...

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 .

Hahaha! ok ok. Noted.

K

both gx740 & gx800 using 60Hz panel, aren't they?

Received my TV last weekend, happily unbox but found that the screen cracked.
Took some photos and arrange for return.
Dropped the TV at POS office this afternoon.
Now not sure want to get the same model again or not.
Please share your experience on this model to convince me get the same model again.
hahahaha......
