In the name of the big screen, the history of the next-generation display technology has long been debated. OLEDs, Quantum dots, lasers, etc. are not yet definable in the future. However, another trend in TV development has been achieved in the industry. The consensus is that "big screen". Data show that from 2016 to 2020, the annual compound growth rate of large-screen TVs with 85-inch and above is 110%, and the large-screen TV market will soon increase rapidly.
The pursuit of large screens meets the needs of humanity, but as the size increases, the price increases in a non-proportional way. If you want to experience an ultra-large 100-inch TV, you must pay 10 times or even dozens of times for a 50-inch TV. . Therefore, the task of saving large-screen televisions falls to the cost-effective and ultra-large screen of laser televisions, which is the protagonist of our evaluation today, Hisense 88å‹4K laser TV LT88K7900UA.
The 88å‹4K laser TV LT88K7900UA is the second 4K laser television launched by Hisense. The first is the 100å‹4K laser TV LT100K7900UA released last year. It can be seen from the naming that the two machines belong to the same series and differ only in size. In fact, the 88-inch 4K laser TV is not only a small version of the previous version but also an upgraded version. Why do you say that, the following detailed evaluation section tells you the answer.
The dominate of the super-large screen market - laser television Although laser television has occupied the vast majority of the market share of the large screen, there are many brands in China, including Hisense, rice, nuts, etc., but many people are still on the laser television. What is not clear. What is the difference between it and traditional TV? We need to re-conceptualize literacy.
The essence of laser television is a cinema TV that uses ultra-short-focus projection technology. In principle, it is the same as the projector. It uses reflection to project images or video onto the screen within a certain physical distance.
Three major parts of laser television: host, screen, and stereo Traditional projectors are generally only mainframes. They do not come standard with screens (curtains) and sound systems. This brings two problems. First, you need to buy your own curtains, installation, and debugging. It takes time and effort. Second, due to the limited size of the main body, the built-in speakers are usually small, the power is generally around 10W (single), and there is no bass unit. What's even more bizarre is that with different installation methods, such as desktop front projection, lifting, etc., the direction of the sound is also different. In the absence of external audio, the sound experience, uh ... really have to hear a ring.
Hisense 88å‹4K laser television is mainly composed of three parts, using DLP ultra-short focal host, 88 Fresnel passive bionic screen and 5.1 sound audio, a set of basic home audio and video system is fully equipped.
Look at the host section first. The appearance of the host part is consistent with the previously released 100-inch 4K laser television. The upper shell is imitation metal silver sandblasting, which feels very texture; the lower shell black light effect is quite stylish; the measuring end is a waffle grid design. , a bit of classical charm, the overall presentation of Founder domineering style. From appearance and design alone, it can be seen that there is a huge difference from traditional projectors. Regardless of material, craftsmanship or design sense, Hisense 4K laser television more closely follows the design language of television rather than projection.
The size of 660*384*210.5mm and the weight of 17KG have to be slimmer compared to the 100-inch version. The sister of the editorial department can hold both hands together. Compared with the LCD TV with the same size, it weighs 100 kilos, it is considered as It is light. Because the design and the color value are very good, and the home environment is also very wild, more importantly, the small size, light weight, easy to move, bring more possibilities for the layout of the home audio and video environment.
At the top of the depression is the lens, placed in the middle of the mainframe is very low-key.
On both sides are cooling air ducts, which take the machine's internal heat through the right and left, and the waffle grille has a very design sense. It draws a clear line with the broken grille and marks its own high-end positioning.
The keys are all concentrated on the top turntable. This design is still quite new and unique. The volume can be adjusted by turning, the stepless adjustment is adopted, the damping sense is good, the navigation machine and the confirmation key need to be pressed, and the light is turned on after the power on and during the operation, and the sense of technology is full.
Most of the interfaces on the back are centralized, with three HDMI 2.0 interfaces (one supported), one network cable jack, and component audio and video interfaces, coaxial interfaces, AV input interfaces, VGA interfaces, etc. With.
In addition, the right side has a USB 3.0 interface, TF card slot, the left side needs to open the gusset, which has two USB 2.0 ports, connecting U disk, mobile hard disk and other peripherals is very convenient, no longer need to blindly inserted in the back .
The 88-inch laser TV's remote controller was completely redesigned. The previous generation of white silver edges became a brushed gray texture. The 19-key still remained simple. The key layout is consistent with the TV system menu and is very easy to use. Infrared + Bluetooth dual connection mode, do not pick the location, do not pick posture, and the remote control also comes with a microphone to support voice control.
The back is staggered stripes, enhance the feel, while the arc is not as big as the previous generation, personal feel more stable.
On the screen, the 88-inch Fresnel passive bionic screen is really big compared to the TV. We took a 43-inch TV as a reference object and instantly became a lot of minis.
However, it is a passive design, no power supply, there are no other components, the overall weight is not heavy, almost no installation, hanging on the wall or shelf on it.
Fresnel's passive biomimetic screen is very similar to an ordinary LCD TV, not to the soft curtain of a projector. Surrounded by a golden border, the thickness of the border is about 15mm.
The Fresnel passive biomimetic screen has a lens layer with a ridge and a reflective layer on the surface of the screen, which can refract the light projected by the host in parallel to the screen and play a role in gaining. At the same time, the light in the environment can also be reflected to achieve the effect of resisting ambient light interference. Improve the overall brightness and contrast of the screen, eliminate the phenomenon of “seeing light dead†that appears on ordinary projectors, and can be watched normally during the daytime.
What are the benefits of using DLP technology? First of all, the brightness is better. Compared with traditional projection, DLP projection can shoot more light on the screen, which also depends on the technical characteristics of DLP itself. The DMD's strong reflective surface maximizes the projected light source by eliminating obstacles on the light path and reflecting more light onto the screen.
Second, the color is more pure. DLP's unique color filtering process controls the color purity of the projected image. The digital control of this technology supports unlimited number of color reproductions and ensures that the original image is vividly reproduced and the colors are more realistic.
Finally, the volume is smaller. A single chip DMD can achieve unity in size, weight, and brightness. Most home DLP projections use a monolithic structure, so users can get a smaller, brighter, more portable and sufficient to provide excellent image quality. system.
Of course, although the DLP 4K chip of the projector is from Texas Instruments in the United States, in the optical processing, Hisense does have a lot of accumulation, and 320 patented technologies are proof. The optical components of the laser television are not purchased. The key parts of the optical engine and the light source and lens are all independently completed by Hisense.
In addition, due to the use of ultra-short-focus projection technology, the projection 88-inch screen requires only a short distance, so it can be directly on the TV cabinet, similar to ordinary TV.
Hisense laser TV has 3840*2160 4K resolution, ANSI brightness of 2100 lumens, brightness of 2100 lumens in the home machine has been in the high-end position, plus the screen's gain effect, the screen brightness 300nit and LCD TV is closer. The official stated that it can be watched normally without turning off the lights. What is the actual performance? Let's look at it together.
In the first half of the "The Hobbit-Five Wars," there are both the highlights of the fire and the dark scenes of the night. Hisense 88 laser television shows a very wide dynamic range, bright highlights without over exposure, dark details can be well preserved. It is very precise in restoring the skin color of the character, and the warm yellow color printed on the face of the flame is extremely true. Because the screen is big enough, you will feel the entire face in front of you, which is quite powerful. The overall warm color temperature is similar to that of cinemas, and it will be more appealing to the eyeballs.
This photo taken after opening two indoor dome lights was not significantly affected. The brightness of the screen was reduced, but there was no whitening and color deviation. The visual experience was basically the same as that of the lights. Household projectors can only be used when the light is turned off.
Let's talk about color.
The imaging principle of the DLP projector has already been mentioned in the foregoing, and it is believed that the laser light source brings more pure and accurate color, and the Hisense 88å‹ laser television using the blue laser light source can achieve 82% NTSC color gamut.
Specific performance to see proofs.
Through the observation and screen capture of a large number of proofs, if you compare the Hisense 88-inch laser television in a projector, this should be the absolute top level in home projection. Accurate color reproduction, strong sense of transparency, green leaves in the first picture, the vivid green color performance, and structured. Since the laser television is a reflection type, the screen looks very soft. No matter whether it is a bright or rich color, it will not be as hot as the LCD TV. Due to the large size of 88 inches, even with the 4K resolution, the fineness of the picture is still lacking when you look closely. This can only quietly look forward to the arrival of the 8K era.
In the aspect of dynamic picture, due to the function of MEMC dynamic image processing system, a frame of motion compensation frame is inserted between the traditional two frames of images to increase the refresh rate of the frame, so that the dynamic picture can be made clearer and smoother.
We tested by playing a 4K high-definition sports video. The performance of Hisense's laser TV was really smooth, there was no jitter, and occasionally there was slight tailing, but it had reached the top level, because I have not yet seen a completely no Smearing TV.
While testing 4K movies, we also experienced the sound performance of Hisense Laser TV's 5.1 sound effects. This is a live video of a concert and you can feel the sound field is very wide. You should know that the size of the sound field in the home theater system directly determines the performance of the telepresence. Adding surround sound makes people feel like they are on the scene, and the symphony's majestic features are reflected most vividly. Because of the bass unit's blessing, bass is much deeper than normal TV.
In addition to the broader sound field, the overall sound is thick and full, especially the clear treble is impressive.
Great performance leap forward The gaming experience is more fun. With the use of Morningstar's MStar 6A938 processor, this is currently the top processor for TVs, used by different brands of flagship TVs, and also with 4GB of running memory and 32GB of body storage. Such a luxury configuration can hardly find an opponent in the market. Hisense can see the luxury of this laser television material.
The core part of MStar 6A938 is that its addition can effectively improve the overall expressiveness of the picture, especially in the three aspects of picture quality, sound effects and functional performance, and has reached a flagship level in all aspects. The biggest advantage of the MStar 6A938 is that it is optimized for Internet video content. As we all know, in different video content platforms, the video definition available for consumer on-demand is various, such as our common 720p, 1080p and 4K. The higher the picture clarity, the better the user's experience. MStar 6A938 can carry out technical processing for different sources of video content to maximize the overall performance of the picture, which is unmatched by other chips. The importance and practicability of this point need not be overstated when the network video is widely used.
With the addition of the MStar 6A938, only 24 frames of Internet video content originally appeared to be smoother and more natural. This fully demonstrates that the MStar 6A938 has a strong frame interpolation technology. Another example is the currently high-profile HDR technology. The MStar 6A938 is more in place for HDR technology. It also enhances the screen brightness while still leaving details. This is a great example of the outstanding performance of the MStar 6A938.
At the same time, the decoding capability is also very good. It supports the global mainstream 4K encoding format HEVC 4K2K@60Hz 10bit, VP9 4K2K@60Hz 10bit, H264 4K2K@30Hz, HEVC dual decoding, AVS+, MPEG4, DIVX, etc., and is called the all-round player.
The use of this powerful processor to play the game is exceptionally fluid.
Familiar VIDAA system contracted your entertainment life Hisense laser TV is equipped with TV-like VIDAA system. We are familiar with this interface design.
Enter the main interface. The main interface uses waterfall flow design. At the top is the status bar, showing sources, notifications, weather, dates, and more. The middle section shows the recommended content, which becomes the corresponding content as the following pieces of “Fine-looking†and “College for learning†are switched.
The main contents of the entire system are centered on the five "poly" prefix applications built into Hisense. Let's look at them separately.

Hisense laser television access is the ICNTV broadcast control platform, and cooperates with Tencent, and has many video resources such as penguin theater, top theater, Tencent sports and so on.
The collection is about 18,000+ movies. Most of the movies support 1080P HD format, some are 4K, and the playback process is smooth. Thanks to the advantages of high picture quality, some of the details are excellent, and there are no trailing phenomena in action or fighting. You can enjoy a large screen. Pleasure.
Among them, free movies occupy the most part, and even if they do not pay, they can meet most of the video needs. Payment is also very simple, you can use micro-scan code to pay, fast and safe.
Get together to learn - at home, you can listen to the teacher's teachings. Hisense is a family education product that is suitable for all ages. Compared with other brands, TV content is mostly limited to children's and elementary schools. It has very obvious advantages.
Poly's enjoyment - the massive merchandise network is the main online shopping platform for Hisense. The products sold are from direct mailings in bonded areas all over the world. They support genuine and inspection services and ensure the carefree shopping.
Gathering fun - the big screen game is a fun game that is equivalent to Hisense TV's game center, which was launched by Hisense and Tencent. Built-in game resources are very rich, role strategies, chess and cards, leisure and entertainment, everything, even somatosensory games, handle games are also included in all kinds of very rich. Even serious host games are impressively listed, and indicate "recommended 10M + network", very intimate.
All-in-one: The universal app store uses the smart app store that is equivalent to Hisense TV. It can download all kinds of applications and can also easily manage installed applications. It even includes free running memory and cleaning system garbage. Can manage U disk, play the content on the storage device.
One of the great advantages of smart systems is that they support various APP extensions. Sometimes applications in the application store do not meet the requirements. This time, they need to be installed from media such as USB flash drives.
First of all, will download a good APP, the format of the apk file on the U disk, inserted in the laser TV, find the U disk assistant on the home page, click to select the relevant file to install.
Defining the ultra-large screen Hisense laser TV To subvert your audiovisual experience The development trend of the super-large screen has become irreversible, and Hisense has already taken the initiative in the laser television market. Relying on laser light source and ultra-short-focus technology, it can get rid of the many flaws in traditional projection, and get a large-screen visual perception through TV experience. At the same time, taking into account the cost-effectiveness, Hisense introduced 88å‹4K laser television to let consumers have new dimensions. The choices have undoubtedly increased the purchasing power of those users who are ready to start large-screen televisions, paving the way for laser televisions to enter more homes.
As the main product of Hisense's laser TV, the 88-inch version reached the top level in terms of brightness, color, and contrast. Under the trend of big screen, compared with LCD TVs, laser TVs are still leading multiple positions in terms of price and size. Think about the price of Sony's 100-inch TV, 500,000, and really think that laser-TV is an unbeatable value for money. Together with Shanghai Xinxin, the content industry was laid out early to ensure the richness of laser television content and provide a guarantee for the top audio and video experience. The next step is to wait for the big screen market to explode in 2017.

What is not clear. What is the difference between it and traditional TV? We need to re-conceptualize literacy.
Projector in the video room
Many people wonder why it doesn't have a huge lens to reveal its identity as a projector. Why can it be placed on a TV cabinet like a TV without hanging far from the ceiling? Why can't you look at the curtains as clearly as the TV? Do not worry, combined with Hisense 4K laser TV LT88K7900UA, we answer one by one. Three major parts of laser television: host, screen, and stereo Traditional projectors are generally only mainframes. They do not come standard with screens (curtains) and sound systems.

In the absence of external audio, the sound experience, uh ... really have to hear a ring.
At the top of the depression is the lens, placed in the middle of the mainframe is very low-key.
Front audio and surround sound
The final is a 5.1 sound system. Hisense 4K laser TV is equipped with a Live Sound 5.1 independent sound system, equipped with left and right audio channels, surround sound and 8-inch subwoofer, and supports DTS+Dolby dual decoding technology to truly achieve surround sound effects. It also supports Bluetooth connection. If you do not have a laser TV host, you can connect to your phone via Bluetooth, play music on your phone, or connect to the host directly via Bluetooth, which is very convenient. How does the specific sound quality behave? We will talk about it in detail later. Bass unit
The DLP 4K+ laser light source has a completely new look. With the DLP 4K chip from Texas Instruments, the DLP (Digital Light Processing) technology principle is: first digitally processing the image signal, and then Project it out. It is based on the Digital Micromirror device DMD (Digital Micromirror Device) developed by Texas Instruments to complete visual digital information display technology. What are the benefits of using DLP technology? First of all, the brightness is better. Compared with traditional projection, DLP projection can shoot more light on the screen, which also depends on the technical characteristics of DLP itself.
