It sounds like you have no idea what you are talking about , at all

NOTE : MY apologies for going off-topic , as this involves discussion of more than Hisense TVs.



You are touching several subjects here at once .

The screen coating has no direct impact on the native contrast ratio of TVs .
Most of the current TV displays on market use a form of glossy screen , it is a matter of semi gloss , normal gloss or full gloss .

Full gloss screens are more pricey than the semi glossy because it is able to reflect more lights off the screen . Therefore under the influence of strong glare, it can retain the black levels better on the surface of the display . This alone has nothing to do with the TV's native ability to display black levels , which we will discuss below.

With interference of ambient lights , it is rather hard for untrained eyes to distinguish true black levels . But the TV with better screen coating will generally look better in a brighter room. Most , if not all of Hisense TVs share the same semi gloss screen finish , while all of the current OLEDs use the higher end full gloss coating , they are not in the same league .



Next , we will talk about the VA TV's contrast ratio.

VA TVs are known to have great native contrast rating, it can show incredibly deep "blackness" which has dramatic impact on picture quality .
However VA TV is still LED-LCD based screen , no matter how hard they try , they cannot compete with OLED pixel levels of light controls . Maybe one day when they are able to squeeze 10000 localized dimming zones in a consumer TV , that is when we can expect an " almost OLED " performance .

To better understand the difference, here is a comparison between a VA TV of 6000:1 contrast ratio (which is pretty good ) and an OLED .
The following picture is taken from a scene in Guardians of the Galaxy 2 , both TVs are using their most accurate picture settings , I trust you can instantly tell which is which.




You are mixing 2 different things together, the screen coating quality and the native contrast ratio , and comparing them with something that is completely different.
If you want to make a compliment on a TV , it is fine to just say the TV has great PQ . Almost OLED is a very bold claim , regardless of whichever TV quality you are talking about back there .

From the pictures yes , because it is a SDR camera . It is unable to fit the wider dynamic range of HDR TVs into SDR pictures. Therefore in order to show you the difference , I had to adjust the exposure of the cam . In reality the OLEDs don't crush the blacks when calibrated properly.

I was simply trying to demonstrate how big is the gap between the black levels from a VA TV with pretty good contrast levels to an OLED.

They have a lot of competition in US , between Hisense , TCL and Vizio .


All these great budget TV seemingly share the same flaw , the very poor screen uniformity which is also a sign of poor QC.

The reviews have been bashed by many , the guy is currently apologizing and trying to redo another video.




As I have previously mentioned multiple times , youtube TV reviews videos absolutely cannot be taken seriously into direct comparison.


For eg : you are comparing 2 TV , one with WCG and one without .

How do you showcase the difference of wider range of colors, on a Camera with limited dynamic range ?
Anything that is too bright for camera will appear to be blown out and muddy on video , but in real presentation it will look entirely different.
Even if we consider the possibility that , this guy has somehow by miracles , managed to squeeze all of these quality into a highly compression youtube video , most of you are not watching the video with a $147000 BT.2020 monitor , how can you tell the difference ?


Any credible TV reviewers ( not like there's many on youtube ) should always start the vid by warning its audience , what they've seen in the vid should not be used as a direct comparison. Instead they should be listening to the interpretation of the reviewer.

Fact that his silly review are confusing people into thinking H9F is on par / better than A9G , one of the best OLED TV , is nothing short of hilarious .

Rtings still has all the numbers , each are measured meticulously with professional tools.
This guy has done nothing of sort and literally has no idea what an accurate picture should look like to begin with.

You are comparing with the worst example Samsung can do .
Numerous cheaper TV out there can reach 400 nits including Sony's X700F , UK7500 , Samsung's Q60R just to mention a few.



Whether if it is 300 or 400 nits will not make a difference , they still don't nearly have enough brightness to project higher dynamic range than a traditional LCD monitor.

The calibration sheets linked above looks really terrible out of the box btw .
Even under the most accurate Cinema modes they have strayed so far away from the standard 6500K .

The DCI-P3 color coverage is pretty poor and has not reach the 90% demanded by HD Alliance to be considered as HDR TV despite being advertised as WCG.
Colors reproductions errors are also exceptionally high , but that is to be expected from most Chinese brands . Although they do have a CMS and 20 points settings for White balance if you plan to calibrate the TV.

Reminded me of a time during world cup event from last year , I walked into the shop and being surrounded by the World Cup sponsor's TV where all the soccer field looks yellow instead of light green.

Correct .


To sum it up , the UHD alliance standard requires TV with wide color gamut , to cover at the very least 90% of the colors from the DCI P3 color chart , which is what most HDR movies are mastered at .

Sony and Samsung , at the very least do make they adhere to the standards .
RU7400 , NU7400 , X7000G are all verified to reach 90% .


Can't say the same for others and many Chinese brands though ( not going to name them before their legion of fans bomb my inbox) .

There is a local brand here which openly advertise their TV of having wider color gamut and their actual coverage is worse than LG'S entry model RGBW TVs .

You mean 90% .

80% you are still missing 20% of the DCI color palette . And then moving on to some movies which are mastered at Rec.2020 , it is going to miss even more .
And WCG is only the first step , there is also color volume which is typically the strong point of Quantum Dots and very bright FALD TVs .


Every modern TV can call themselves a WCG TV thesedays because the modern basic 4K TV can cover 70-80% of DCI chart which is still more than the traditional SDR TV which is only meant to fill up the old rec.709 .


I believed all the big TV brands (namely the big 4) have a certain standards to adhere to . So if they are saying their TV supported WCG , it means that tv can practically reach over 90% of DCI , or at the very least close to the 90% set by UHD alliance .


For eg , LG has specifically mentioned their UM7600 covers a wider color gamut , except the 50 " model which will probably fall short of the 90% .

Dolby Vision is a type of HDR format , like HDR10+ , HDR10 , Technicolor and so on.

WCG being one of the hardware requirement to display vibrant , impactful and realistic HDR effects.

So to sum it up , TV of any spec with DV chip installed can theoretically play DV content , but whether if the Dolby Vision will look as vibrant and as good it should , that will have to depend on the TV spec with WCG being one of the requirement .

here



I don't know much about UM7290 or UM7300 , they are not officially listed on LG 's catalog .

If I have to guess they are identical to the basic RGBW TV UM7100 with minor changes .

If you are obsessed with the numbers , Hisense should never be in your consideration anyway .

They are a Chinese brand ( and I don't mean that as an insult ) .

They only have to appeal to the audience in China & people with rather tight budgets and are just looking for a screen to watch .
They never have to adhere to any rules set by the industry .


You cannot even calibrate their TV properly because the SDR settings overlapped with HDR .
And the colors are so inaccurate out of the box it isn't funny .



Although these Hisense TV tend to have pretty good build quality compare the budget models from the other brands , they are pretty heavy ( indication of good quality builds ) and use less plastics .

If you are talking about the overlapping settings , nope . It has already been this way for years , doesn't look like Hisense is planning to fix it anytime soon .

132 .

And I really don't think so .

We usually follow the European Standard and the European equivalent of UQ800F , which is the U8QF has a 8bit + RFC screen , the H9 series of Hisense from US has native 10 bit .



Regardless , be it TCL or Hisense , we rarely get the same product quality outside of US .

1000 theoretical brightness , similar to x900h but not anywhere close to 1000 post calibration.



Actual brightness should be closer to 600 .

Since the settings of SDR and HDR are overlapped , I doubt it will reach even 600 . Good thing is it still has the FALD system , should compensate some of the contrast ratio in HDR scenes .


180 on 65" is still nothing to write home about and their local dimming algorithm is kind of crappy too .

The difference between 10 bit and 8 bit + RFC is particularly obvious in high brightness scenes with color banding , the dithering method doesn't work very well in gradient transition .

The Q95T has an ultra powerful screen which can reach 2000 nits peak with wide viewing angles filter , they are not really in the same league .
The Samsung model also has a color gradation smoothing feature baked into the noise reduction setting , Hisense doesn't .

No .

None . We simply don't get any of those excellent TCL and Hisense TV in Asia .

Which is in line with what we have been talking about in this forum .

Hisense , great specs & great hardware but subpar picture processing .
It is the same few things that have been plaguing the brand for a while .



What a lot of people in the forum didn't realize is , when they are buying the " big 4 " they are essentially paying for the decades of experience these brands have invested into finetuning pictures , not just the hardware .
You will not get to the top of the industry by dumping a massive amount of money and expecting your engineers to become elite overnight.

These ABC from China may have a deep pocket but they definitely lack experience .

Like a certain "X" brand , they could be selling you the same tv at half price but you will never see red [the color] on their display , its all orange and magenta regardless of calibration .
