Haisin NU7700 TV picture quality test
As a high-end TV, the picture quality is also the most important part of the picture test session, we are mainly on the screen itself the basic quality of the test, including the objective data test and the actual photographic test of the two major items. The test data through a professional instrument (TOPCON's BM-7 Glow Meter) on the TV screen brightness, NTSC color gamut range, light and dark contrast, dark field performance and other aspects of the test. The photo taking part is mainly to play selected different types of movies such as people, landscape, night scene, sports, etc. under dark room conditions with an external USB flash drive of the TV, to test the dynamic clarity and detail reproduction of the picture.
▲BM-7 (Glow Meter) test process
For the color, the measure of good and bad standards is one is the color gamut, and another is the color accuracy, which is the color gamut is the range of the color range of the interval, for example, the human eye a **** can distinguish about 10 million kinds of colors, then the TV itself should be as much as possible to render these colors, so we introduced the NTSC color gamut concept (American TV standard). The concept of NTSC color gamut (developed by the National Television Standards Committee of the United States), as for the color accuracy, the best test method is still through the human eye to observe the difference between the contrasting display and the color in the TV display.
After the professional instrument BM-7 test, Hisense NU7700 TV's specific picture quality performance parameters are: default setting conditions, the measured brightness reached 416.4 nits, higher than the general LCD TV 300 nits of brightness, the black field brightness has been lower than the instrument's limit of 0.01 nits, there is no obvious phenomenon of light leakage, it can be said that close to the infinite contrast ratio, the performance is very good; the measured NTSC color gamut reached 90.7%, significantly higher than the current mainstream TV 72% color gamut range, killing the vast majority of TVs on the market.
▲Color gamut test results
The next test is in HDR movie playback, where the Hisense NU7700 automatically recognizes HDR-10 format movies. Due to the limitations of the camera's sensitivity, the photos don't fully reflect the true picture effect, but we can still clearly see through the naked eye that Hisense NU7700 is not only bright, but also very well preserved in detail, which has reached the current top level. You can observe the intensity of the sun and water light in the following pictures, the texture of the tiger's back, the details of the dark parts of the water, can also be more objective response.

Haisin NU7700 TV sound quality test
Nowadays, for a TV, the degree of importance of the sound quality has been no less than the picture quality aspect, consumers are eager to get out of the home to get the theater version of the shock effect. Hisense walked before other manufacturers, the first in the new NU7700 series on the use of dual-mode *** vibration ultrasonic sealed sound box, through the air vibration directly into the ear, can be presented 3 times the volume of the traditional inverted-phase speakers of the bass performance, so that the bass performance is more mellow, level, Hisense will be the patent-authorized sound technology named air sound field.
▲Airborne sound field technology
Why is airborne sound field technology better than traditional speakers? We still have to start from the principle, first of all, in the history of the TV sound, inverted phase speaker (subwoofer conduit) appeared to make a small volume of bass become possible, this technology in the field of TV is still the mainstream audio structure way. But as TVs get thinner and thinner, the ultra-thin cabinet space can't meet the inverted-phase speaker for the cabinet volume and speaker size requirements, in the reduction of complex low-frequency sound will feel the more obvious shortcomings.
Compared with the traditional TV inverted box, Hisense NU7700 influence series products using dual-mode *** vibration ultrasonic sealed sound box, through the air vibration directly into the ear, avoiding the sound pipe link sound wave loss and clutter distortion effect, closer to the physical nature of the sound conduction, can be rendered three times the volume of the traditional inverted speakers of the bass performance, so that bass Performance is more mellow and layered. With the addition of two passive radiators, the bass effect is dramatically improved, resulting in a more powerful bass sound compared to audio systems of the same size.
▲Super Bass Effect
In order to prove its actual effect, we quoted the testing data from the National Center for Supervision and Inspection of Digital Audio, Video and Multimedia Product Quality: Hisense NU7700 has outstanding bass performance, with the lower limit of the effective frequency range of the low-frequency reaching 56Hz, and the bass section has a very strong expressive power.
At the same time, in order to create a theater-class feeling, realize high fidelity, no distortion of the ultimate experience, Hisense NU7700 influence series application of the Grammy Technology Gold Award Waves sound processing chip, its sound processing technology by the world's more than 400,000 professional studios to promote the use of NU7700 series of products at the same time both the DTS and Dolby dual-decoding sound processing system, at home can experience the theater-class shock of the processing system, can also be used in the home. The NU7700 series is equipped with both DTS and Dolby Dual-Code audio processing systems, allowing users to experience cinema-quality audio and video at home.
In the test section, we selected a special demo disk and the HD blockbuster movie "Iron Man 3" for playback experience.
▲HD DTS Surround Sound Source
Haisin NU7700 is one of the few TVs on the market that supports Dolby and DTS*** decoding and post-processing technologies, and Dolby, as we all know, is basically used in Hollywood movies, and movie theaters in addition to powerful audio are generally equipped with Dolby technology. Dolby's technical support to achieve a shocking sound experience, unlike wearing headphones with a computer, Dolby sound generally have to be in a separate sound system in order to get a good show, Hisense this set of sound system fits this point, can be a good play out of Dolby's technology, in this way, when watching a movie can be over to get a better experience, the virtual surround sound can make a person as if you were there.
And from the sound performance, due to the existence of special air sound field technology, which makes the sound source more pure, the bass is more shocking, further enhance the sense of presence when watching TV. From our HD test film "Iron Man 3" playback experience, the most impressive is undoubtedly the low-frequency, the body of the increase of two passive radiators, to the NU7700 brings a thick bass texture, which we can be from the explosions, Iron Man armor impact and Tony's low voice clearly perceived, the ordinary ultra-thin TV in the processing of these sounds will be dry and hard.
▲"Iron Man 3" playback experience
Mid-high-frequency part of the Iron Man segment of the glass breaks at the sound of the most illustrative sound, with air sound field technology audio using a fully enclosed design, the high-frequency signal can be processed independently of each other, through the air directly into the ear, to avoid the loss of sound and noise, to ensure that the glass breaks down when the sound of the details of the expression, and there is no broken sound or sharp, the noise of the sound of the sound of the sound of the sound of the sound of the sound of the sound.
▲Audio playback experience
This time to watch a nature documentary or "Tongue in China", simply feel the wind and leaves on the side of the swaying, the chef is in front of you live cooking, the real "ultimate audio and video enjoyment" is not the same as it is!
In order to meet the needs of different people, in the sound menu, including standard, music, news, movies and other sound different modes can be adjusted to bring better audio and visual enjoyment, to ensure that users get the best sound effects.
▲Sound Mode Adjustment
Another highlight worth mentioning is that it also supports Bluetooth connectivity, which allows you to listen to music on the TV's speakers when the screen is turned off. In this way, in addition to the TV itself, the user's own cell phone, tablet, or any other Bluetooth-enabled device can use the sound, which allows you to get the most out of the sound system, even when you're not watching TV. The best of both worlds. The advantages of Bluetooth connectivity also include eliminating a lot of wire hassles, making the desktop fresher and easier to maintain.
