Home Hi-Tech Audio / Video / TV / Streaming ,,,,, We have told you several times about Hisense TVs and the technologies that the Chinese company has used to rival the most popular brands in the field of large format TVs. HiSense sent us their gigantic H75U9A for a test which, even though it was not, in fact, the official TV for the world championship wanted to be the most powerful (and biggest) available on the market in the summer-autumn 2018. And big it. it is really seen that we had to place it astride the TV cabinet practically “bridge” on the ends and with such a viewing surface combined with a sofa positioned at about 3 m: we practically lived “inside” the Netfllix films for 4 weeks, Amazon Prime and sporting events and even those in 4K of SKY Q since the TV is compatible with the HLG format.

Design and assembly
When we saw this boundless panel delivered we were slightly astonished: to get it into the condominium lift we had to put it vertically and for the unpacking and assembly we had to resort to the help of a collaborator above all to avoid damaging the screen: to tell the truth, the full-bodied and well-structured chassis helped us: it is a TV that does not aim to be the thinnest on the market and favors solidity and performance. A complex ultra-defined backlight system is mounted on the back and the sound box is used to increase audio performance.
It is useless to deny that the rigid structure is also a good help for assembly and movement: in any case, two people are needed to insert the transparent plexiglass element that rests on the back and the “U” bar that ends in front of the front soundbar: in the end we will have a very interesting “tripod” configuration that seems to make the heavy TV rise on the table top. Surely it is not a beautiful TV to see on the back and side but the large screen and the well-designed front manage to compensate for this lack.
The direct and immediate controls for the TV (power, volume, channel, source ) are located in the front bar on the right.
Connectivity
Arranged in two areas on the back with one appropriately recessed and the others that will require cables with an “L” plug if mounted on the wall, the connections of the TVs are generous: 4 HDMI (attention only 2 are 4K HDR at 60Hz, the other two are 4K HDR at 30Hz), three USB, ethernet and obviously antenna. 
The technology
The strengths of the screen are essentially two: the presence declared by Hisense with “Prime Array Backlight” of 1056 zones for local dimming with 20550 Nits of brightness and a high dynamic range and technology Quantum Dot that together make the TV deserve the UHD Premium label. Labels apart from such precise local dimming management it certainly helps to achieve high black levels and the Hisense Peaking Brightness Process algorithm helps to maximize the brightness range and improve the contrast at least twice (according to the company's claims) compared to a traditional LED TV. Hisense also adopts new motion estimation and compensation technology by doubling the fluidity in fast-moving images. Backlight Scanning technology helps reduce the wake effect and results are appreciated directly in football matches and other dynamic sports.

The sound
Thanks to the generous chassis that doesn't sacrifice depth in favor of audio performance, the sound of this TV is truly top-notch. Although obviously we do not have Dolby Atmos, the system recreates a surround system starting from the front bar that can make purists turn up their noses but which still maintains high quality levels, excellent presence and good dynamics. Tweeter, Midrange and Woofer are separated and take advantage of the huge sound box available behind the panel. The arrangement of the speakers helps more those who install the TV in a medium-low height cabinet, let's say at 45-60 cm from the floor and is positioned at about 2.5-4 meters from the TV for a totally immersive experience. 
Smart TV and remote control
HiSense is not based on Android or a operating system as LG does with webOS but manages everything through its simplified smart interface VIDAA U which objectively, although easy and fast to navigate (on board the TV there is a quad core processor) is not up to par in terms of content compared to the competition: there are all the streaming and video services you need and we spent entire weekends watching the 4K HDR demo videos of YouTube, series on Netflix and Prime but the interface when it starts takes up the whole screen and maybe you would like to keep under control current broadcast before choosing another broadcast or streaming service.

Not having received the remote control by mistake in the first days of testing, we “made do” with the “RemoteNOW” application on iOS and Android which allows the control of the TV and the projection on the big screen of images and videos taken on the smartphone: convenient when you do not find the remote control but obviously the traditional system is more convenient especially for normal TV channels. Convenient the possibility on the remote control to select Netflix and good ergonomics even if the design does not appear particularly refined. 
Tested with 4K, HDR, Sky Q, upscaling
We have tried the different HDR viewing modes and certainly the one called HD Dinamic even if it enhances the brightness of the screen even more and tends to lighten the scene a little but working on the global brightness you can balance everything. There are no shadow phenomena on the sharp edges bordering white. The management of blacks with a few adjustments allows you to get excellent results that cannot compete with OLEDs but that thanks to the resolution of the backlight offer a good compromise with an alternative technology. The adjustment of the backlighting is fundamental and the right balance must be found between the maximum values that offer deep blacks and a little “blooming” on the intermediate areas, a mild adjustment that brings a bit of “clouding”. Obviously these are details for enthusiasts: all the spectators we invited to watch on the big screen said they were amazed at the quality of vision both on scenes with strong contrast and on more balanced scenes. The upscaling does a good job but obviously forget about having the best on low-resolution local TV broadcasts: obviously better to switch from the HD channels of the digital terrestrial with a signal that performs well even on the large HiSense surface. 
With the VIDAA interface, although simple, you can quickly access (or even earlier with the button on the remote control) Netflix which offers a range now abundant with 4K broadcasts including the beautiful Chef Tables where the saturated colors of the food stand out to the maximum. Marvel series like iRon Fist have some background gray but it's hard to understand how much this is due to the TV and how much to the digital material. Dolby Vision and HDR10 modes are not provided but the compatibility with HLG allowed us to appreciate the few sports broadcasts of Sky Q before the start of the football championship and the films in 4K. An interesting source of demo films is undoubtedly YouTube cha an immensity of films and documentaries in 4K HDR and even 8K which on this TV stand out for their brightness and “immersion” given the enormous size of the panel. We also tested it with Fifa 18 with PS4 Pro and Fortnite and we must say that the lag time and in any case the good quality in the action scenes do not bother the more “compulsive” players at all. The lag time is approximately 45 ms. 
Do I choose a large screen or a 4K projector?
“important” price of this TV leads it to compare with those of native 4K projectors that are populating the market. A 75 ″ diagonal really makes the difference if we want to reach the maximum of the ratio between brightness and size. A projector 4K in this price range will hardly reach the 2500 Nits of this HiSense and above all the yield cannot be comparable in a partially illuminated environment such as the living room on a Sunday afternoon or a room open to the public impossible to obscure. From the point of view of practicality, certainly the backlit panel has no competitors and with these dimensions it is able to approach a projector diagonal without having to position the source on the ceiling or connect cables to the amplification system. The good “embedded” amplification system adds an extra versatility feature.
Conclusions
One of the brightest TVs we have ever been able to observe: even if black cannot be compared to OLED models and even the smallest and most recent Samsung, the performance on a panel of this size is absolutely appreciable. With some sources the HDR seems slightly desaturated but it is possible with a little bit of adjustment to manage a personalized profile suitable for the most engaging films. The clouding traces of the backlight in some cases make the images slightly “hazy” at least on some Netflix content. The strengths are definitely the absolute fluidity in action scenes and sports broadcasts and an audio that we have rarely heard in a flat screen TV. This is thanks to the intelligent “soundbar” shape of the lower part and a thickness that leaves more room for performance and solidity than for aesthetics. Basically a huge all-rounder TV with high quality images with a vocation to furnish the (large) living room of a sportsman or action movie lover or a public venue that wants to offer quality shows even in broad daylight.
Pro
Support HLG, Fantastic brightness and good work of high resolution local dimming. Excellent sound behavior that does not make you regret the use of a “flat” screen. With the right sources. Great Browser.
Against
HDR + and Dolby Vision support missing. Clouding and blooming effects if a correct backlight adjustment is not found. A little basic smart tv interface.
Price to the public
HiSense H75U9A costs about 3,400 Euros to the public.
The fixed wall support, if you do not want to use it on a piece of furniture, costs about 25 Euros. [amazon_link asins=’B07GVQZCT6′ template=’Grid-Macitynet-Prodotti’ store=’casaverdesmart-21′ marketplace=’IT’ link_id=‘d8db7a0b-dd60-11e6-8bc3-c9d8dd93c2f1′],
