More than 70,000 yuan level, Hisense 4K laser TV L6 depth evaluation

UHD 4K DLP Solution

3840×2160 physical resolution

Peak brightness reaches 350nit

Support HDR10 high dynamic range display

Bringing a surprise leap of quality and sound

Hisense 4K Laser TV L6

Reference price: 79999 yuan (including 100 inches Fresnel passive bionic screen and external subwoofer)

The L6 from Hisense is one of the two high-end 4K ultra-high-definition models in the comprehensive evaluation of laser TV. At the same time, unlike other participating models, this 4K laser TV is not only a host, but also includes 100-inch Fresnel-free. Source bionic screen and external subwoofer, so in this evaluation it is the only laser TV without a unified projection screen. In the core display part, L6 adopted the UHD 4K DLP solution with a physical resolution of 3840×2160. At the same time, with the mature laser light source in the fuselage, the color gamut coverage reached 116% of the BT.709 standard. With the unique Fresnel passive biomimetic screen, the screen's peak brightness reaches 350nit. Compared with Hisense's previous-generation 4K laser television, L6 not only added support for HDR10 high dynamic range technology, but also can fully exploit the picture quality potential of UHD 4K ultra-high-definition Blu-ray and streaming audio and video programs, as well as built-in Harman Kardon’s Advanced audio system, and fully commissioned Harman Karton custom development in the acoustic structure design, professional sound quality adjustment, and configuration of 5.8G wireless subwoofer, the volume compared to the previous generation reduced by 60%, low frequency dive to 40Hz, more Can create a low-frequency dive with impact. Therefore, the overall performance of L6 is a qualitative leap compared to the previous generation 4K laser television.

Functional advantages and expectations

Power consumption: 0.3W (standby)/417W (running)

Operating temperature: 23 degrees (body, room temperature 18 degrees)

Operating noise: 35dBA (measured 1m from the fuselage)

From a functional point of view, Hisense L6 is a very comprehensive laser television, not only has a rich picture adjustment function, but also equipped with a powerful speaker system and detailed sound adjustment, and through the built-in powerful intelligent systems and network functions, you can easily Get a variety of movie shows and other information. Of course, you can also input UHD 4K ultra high-definition Blu-ray source through the HDMI interface on the back of the camera to watch exciting Hollywood movies and enjoy various concerts and concerts.

Image quality features

Non-HDR State Full White Center Brightness/Full Black Center Brightness (after tuning, Cinema Mode), with Hisense 100-inch Fresnel Passive Bionic Screen: 247nit/72fL, 0.053nit/0.015fL. In the HDR state, the brightness of the entire white screen center/black screen center brightness (after adjustment, theater mode), and Hisense 100-inch Fresnel passive biomimetic screen: 254nit/74fL, 0.012nit/0.0034fL. (Based on the needs of the theater viewing environment, the appropriate brightness specifications have been set, and the brightness of the national standard cinema is 50nit.)

According to the test results of color, gray-scale transition and brightness, it can be known that L6 is indeed as shown in the official data, reaching 116% of the BT.709 standard, and in the HDR mode it has reached the DCI-P3 standard. 85.6%. In terms of gamma curve, whether in non-HDR mode or HDR mode, there is a fairly close standard performance, so the details of the highlights and shadows of the picture are very rich. In terms of the overall brightness of the screen, the brightness obtained with the Hisense 100-inch Fresnel passive biomimetic screen is much higher than that of other participating laser TVs, which is closely related to this anti-light curtain.

Testing the Gray Balance of SDR Gamma2.2/D65 and HDR10 Gamma(EOTF)/D65

Figure 1: The L6 test sample in the non-HDR state, cinema mode, custom color temperature mode Gamma's test value floating up and down in 2.2, in which the 20% - 80% range of gray levels slightly higher than the 2.2 standard, close to the level of 2.3 , while the entire grayscale white balance remained at a good level, quite close to D65

Figure 2: In the HDR state, taking into account the Tone Mapping tonal matching factor, the highlight of the Gamma curve from 70% - 50%, 50% below the curve close to the HDR10 standard, the overall picture details are in place, and the white balance The blue part is more prominent

Test the performance of various screen preset modes under SDR BT.709 and HDR DCI-P3 color gamut standards

Figure 1: In the standard screen mode, the overall color gamut achieves 116% of the BT.709 standard, and in the HDR state it is 85.6% of the DCI-P3 standard, while the white point position is slightly bluish and the brightness is maintained at a high level.

Figure 2: The color gamut of the movie screen mode is close to the standard mode, but the white point position is closer to the standard D65, but the brightness is lower than the standard mode 15%

Figure 3: The overall performance of the dynamic mode is close to the standard picture mode, but the yellow is more eye-catching and the white point is slightly bluer

Figure 4: The color gamut in the text mode is small, but the overall brightness is also lower, and the various colors are not very prominent and remain in a soft viewing state.

Figure 5: Bright mode has the highest picture brightness, with green, yellow, and cyan being prominent, and white spots still appearing blue.

Figure 6: Theater mode is the closest to BT.709 among all modes. Regardless of the color gamut or white point, the brightness at the same time is maintained at a good level and there is no obvious decrease.

Figure 7: The game mode has a higher screen brightness, but the overall activity of the color is not as bright

Figure 8: The overall brightness of the natural model is lower, and the color gamut is also the smallest. The white point also has the problem of blueishness.

Professional editors review comments

Li Shengsheng

His new generation of laser TV L6 brought about by Hisense this time really surprised me. Compared to the previous generation, it is without a doubt a qualitative leap. The performance of HDR, especially HDR, was even more outstanding. Among the performances in highlights and shadows, the best performance among all the models in this evaluation was achieved. In terms of its own sound system, it came from Harman Kardon. The configuration is indeed not disappointing, both with rich details of the depiction, but also to create a good stereo field performance.

Deng Guanqi

As a new product of Hisense, the progress of L6 is not big. With regard to its own picture, its performance is second only to the Sony VPLVZ10000 in this evaluation model. The performance of the color, fineness, contrast and brightness of the screen is quite good, and only the aspect of the screen's permeability is slightly different. In addition, L6's pricing already includes a projection screen, a host, and a wireless speaker system. At the same time, L6 also offers many types of online TV and movie program resources, so its overall cost performance is very high in high-end models.

Yao Xiaolin

Whether it is the fineness of the screen, color reproduction, the performance of its own audio system, or other built-in features, the L6 has reached a fairly mature level. The brightness of Hisense L6 is sufficient. In the case of anti-light curtains, it can be used in the audio-visual environment of the lights. The factory's color settings and dynamic settings are accurate enough, and there is not much difficulty in adjusting them later. In addition, the quality of the video resources carried by this laser TV's "Chenhao" video resource platform is relatively high, which is more advantageous than other laser TV products.

Du Xiaowen

Hisense L6 is the most mature laser TV in this evaluation. Online resources are rich in content and high quality. Support 4K HDR, and the picture is smooth, the color is vivid and delicate, and the highlight part is particularly dazzling. The sound system is the best choice for the audience. The volume and dive and details of the bass far surpass some of the laser televisions that were included. With the aid of wireless subwoofers and curtains, the overall audiovisual experience will undoubtedly be even higher.
