Hisense LED55XT900X3DU first impression on the appearance of a very strong sense of metal, panel boxes and edge are made of hard aluminum alloy, compared to the plastic edging appears more upscale, solid. The TV bracket adopts dual stainless steel brackets, and the fixing method is more scientific and firmer.
Backplane uses traditional black engineering plastics. For 4K TVs, heat dissipation must be done well. Hisense LED55XT900X3DU has enough cooling holes and is arranged scientifically and reasonably. However, Xiaobian still sees the strong heat production capability of 4K TVs during the operation. .
The overall tone is warm and warm, with rose gold-colored metal edging, which makes it look upscale and the edge is polished with a beveled mirror finish to highlight the craftsmanship.
Hisense LED55XT900X3DU uses a 5.1-channel system and has six independent channels, giving a different audio feast. The Hisense logo uses a metal relief effect that complements the rose gold frame.

Peripheral interface has three USB ports, one of which is USB3.0, I believe this is also set up for the external 4K resources, in addition, there are humane TF card interface, which will facilitate a lot of not used to use U disk users.
The design of the remote controller is relatively simple, but its function is very powerful. It has convenient and user-friendly shortcut keys and smart home keys. At the same time, it also has voice control keys for the voice system, and 12 keys for convenient text input and channel control. It is worth mentioning that this remote control uses a micro USB charging interface, built-in lithium battery, more environmentally friendly than traditional dry-battery-powered remote control, even if it is only a small detail.
In general, Hisense LED55XT900X3DU has a good performance in appearance, especially the rose gold and gray metal panel boxes reflect the reality and exquisite craftsmanship of domestic TV, and indeed left a good impression on Xiao Bian. But the appearance of light looks good for a TV. It does not make any sense. The good picture quality is the king. This kind of TV that claims to compete with the quality of OLED will have a performance. Not much nonsense, it will enter our image quality. Evaluation it!
â— Picture quality test
First of all, we use the evaluation room professional instrument to conduct detailed tests. In the test, we adjust the TV to the standard image mode, backlight adjustment to the brightest other default, and all the test items and the score results of the product we made a five-dimensional performance chart Put it on the map.
â— Power test scores
Hisense LED55XT900X3DU power test model / picture red green blue black and white color transition Hisense LED55XT900X3DU 235.67w 229.15w 234.46w 72.56w 239.17w 231.35wAfter the test of power consumption meter, the power consumption of Hisense LED55XT900X3DU is still relatively large, and it is no wonder that the TV generates slightly more heat, so the score is 7.5 points.
â—Color performance test
After a professional color analyzer test, the color saturation is equivalent to 89.60% of the NTSC color gamut, while the value of the color gamut of ordinary LCD TVs on the market is only 70%, showing Hisense LED55XT900X3DU performance is still quite good.
In the pixel arrangement of macro shots, Hisense LED55XT900X3DU presents horizontal RGB three-color arrangement, up and down "field word" arrangement, but its boundaries are not very clear, from the pixel specifications can be judged to be Samsung using PSA technology New specification PVA panel.
In the standard test screen of the yarn ball, we can see that Hisense LED55XT900X3DU has a good color performance, the screen color saturation is very high, the demarcation of hairballs of different colors is obvious, the color discrimination is high, and the bonding area of ​​red and pink is It is also very small.
Silk standard test screen can be seen, the color performance is good, saturation is also very high, silk texture can be the ultimate performance, light and shade performance is also good, but from this picture you can see the picture quality is slightly blue.
Character skin color, Hisense LED55XT900X3DU skin color whether it is Asian or white skin performance are more true and natural, the same color saturation is still high, it seems that ULED high saturation really is not blowing.
Summary: Integrated data testing and standard test disc screen shots, using Hisense LED55XT900X3DU ULED technology quality standards in the domestic TV ranks can be regarded as among the best, the color display is accurate and high discrimination, high saturation, plus 4K screen , High resolution also ensures the delicate and clear picture quality. Therefore, we gave 8.5 points to the comprehensive evaluation points in the color.
â—Light control performance test
Brightness test We only adjust the backlight to the brightest, but the brightness value uses the default. This brightness looks more natural, so the parameter value is not very high. However, the brightness parameter of the screen is not the decisive parameter of the picture quality of the TV. Even if the brightness of the screen is low, due to the problem of the factory setting of the panel, products with low average luminance but excellent final picture quality are not uncommon. It can also be seen that the picture quality is still excellent, the picture is clear and detailed, and the various colors are highly discriminating, so this brightness value can be used as a reference.
From the gray-scale diagram, the level of gray level of Hisense LED55XT900X3DU is very obvious, and even the distinction between level 0 and level 1 and between level 14 and level 15 is very obvious. This is inseparable from the regional light control technology. Therefore, in the light control section, we gave a score of 8.5 points.
The ANSI contrast test method uses 16-point black-and-white color blocks. The ratio between the average value of the eight white areas and the average value of the eight black areas is the ANSI contrast ratio. Although in the previous brightness test Hisense LED55XT900X3DU brightness is too small, but in the black and white performance on the slightest half, the two models dressed in black and white models in their own anti-phase background, all kinds of details can be very There is no pressure on the show.
In the test of the black screen, the leakage of Hisense LED55XT900X3DU is slight, biased towards the screen, and there is almost no light leakage in the center of the screen. The light leakage phenomenon is controlled well.
The black and white background map of the standard test disc, the two women's satin evening dresses can be distinguished from the background, including the silk draped over the shoulders; the Tokyo Tower part, the dark block of the middle billboard is very clear, the distinction between the lattices Obviously, the situation of sky light leakage is not obvious, and the dark part is considered as sinking down; the carbon block part is characterized by obvious details, but it is slightly whitened.
Summary: Integrated data testing and standard test disc screen shot, we can see Hisense LED55XT900X3DU performance in the light control part of the remarkable, the ANSI contrast parameter value as high as 4391:1, is also very good.
â— Dynamic performance test
In the dynamic performance test, we mainly observe the details of the TV's dynamic performance through the details of the house on the other side of the window of the train in motion. In the above picture, we can clearly see the edge of the house and The leaves on the tree twigs next to the house, but the noise is a little more, but it does not have any effect within the normal best viewing distance.
Next, look at the comparison with the same frame in the use of MEMC (the principle is to use a dynamic video system, insert a frame of motion compensation frame between the traditional two-frame images, the flat-panel TV 50/60Hz refresh rate to 100/ Can the TV's dynamic processing performance change in 120Hz mode? As can be seen from the figure, the noise of the picture using the MEMC mode is significantly reduced, and the entire picture is also clear and natural. In terms of dynamic processing, Hisense LED55XT900X3DU is undoubtedly very good. Therefore we give it a high score of 8.0 in the dynamic performance evaluation.
Let's take a look at the 2K screen real shot of TV.

Transformers 4 Trailer: 2K to 4K
From the screenshots, we can see that the 2K video is slightly white, the number of noise is high, and the color saturation is general. After 2K to 4K operation, the color saturation of the screen is much higher, and the whitening phenomenon is also improved. More than the original 2K picture optimization, but the picture details appear some vagueness, may be an algorithm problem, it may be the problem of the image engine speed, it is not known. Therefore, 2K resources can also be seen as 4K quality, but you don't need to look at individuals.
â— User Experience: Voice Manipulation
Nowadays, the development of remote control has been developed in the direction of simplicity.

However, some gestures are still difficult to identify through actual testing. For example, exit and page turning are similar to waving the palm of your hand. However, the amplitude and frequency are different. During the operation of Xiao Bian, the number of successful gestures to achieve the exit effect is only poor. , I hope to make the recognition of gestures as high as possible.
