Exterior:
As a person who has seen a lot of domestic and foreign brand television in the store, the moment of seeing this 65-inch Xiaomi TV 4A was simply shocked.
Both the frame and the base are made of black plastic material, without any metal texture, as if it were back to the era of CRT TVs, properly "silly big black".
Millet TV 4A adopts a direct-type backlight, which is naturally a lot thicker than the side-entry type. In addition, the fixing screws of the plastic frame are directly exposed. The overall texture can be said to be insulated from “elegantâ€.
The back of the fuselage is a galvanized steel plate and plastic main board cover, one by one concave above the steel plate is used to fix the backlight. The thinnest top of the fuselage is also 13.2mm. The position of the mainboard and speakers placed under the fuselage is 77.2mm thick.
hardware:

This inch of millet TV 4A 65 in hardware uses Amlogic T962 quad-core 1.5GHz A53 chip, GPU is Mali-450 MP5 750MHz. The memory is 2GB DDR4, and the flash memory is available in 8GB and 32GB versions, corresponding to a "Standard Edition" of 5,699 yuan and an "Artificial Intelligence Voice Edition" of 6,199 yuan.
The bulk of the cost of Internet TV is basically the panel and driver module, plus the TV is responsible for the display function most of the time. Unlike smart phones that have high processor requirements, smart TVs are sufficient to ensure smooth operation, so SoCs are basically at the level of thousands of machines, and do not expect them to play any big games.
Backlight driver board:
Backlight drive + power uses a black PCB board, although the black PCB board quality is better from the superstition made out of Apple Computer, but it does look more advanced sense. The aluminum heat sink and capacitor arrangement on the board are relatively regular, so here is a good comment.
LCD driver board:
Judging from the Samsung chip on the LCD-driven version, we certainly did not run the Samsung panel on this TV. According to the official parameters, the 8-millisecond dynamic response speed is slightly inferior to that of the LG panel for 6 milliseconds, but the 5000:1 static contrast ratio is much better than the 1200:1 of the LG panel. This parameter can also be inferred that this TV is used by Samsung. VA soft screen.
Processor Board:
From the previous figures, we can know that the 65-inch version does not use the "triple board" solution that integrates the backlight driver + power supply, LCD driver board, and processor board into a single circuit board. Instead, it will use higher-cost ones. Non-integrated solution. It's just a pity that the two USB ports are ordinary USB 2.0, and it may happen that an external mobile hard disk plays a high bit rate video.
The advantage of not using "three in one board" is that it is more flexible in the arrangement of common interface positions. It can be placed on the left or right side of the camera as required, and the user experience is better. When hardware problems occur, they can also be replaced individually to avoid costly maintenance.
display effect:
Using some of the 4K test pieces on the hand, there are no obvious defects in the detail and color of Xiaomi TV 4A. However, motion compensation is not supported, so in some high-speed motion scenes with 24 frame formats, Xiaomi TV 4A is vulnerable.
In the face of the green-based scene, Xiaomi's training is also biased to please people's attention. TV is not as professional as the monitor, so pay attention to accurate color reproduction, more often to see the user's eyes, and some like cold and some like warmer, they see the most important thing is to be happy.
The official parameters are nominally 178 degrees visible. As shown in the figure, the actual results are certainly not as good as the data. After the line of sight and the angle between the screens are less than 60 degrees, there is a noticeable reduction in brightness, but the color and saturation are OK. The narrow visual viewing experience of VA soft screen is not as good as IPS hard screen, but how many people will watch TV like this?
The borderline of the 300 nits in the HDR test video is still relatively clear, and the boundary of the 1000 nits is a bit overexposed. At present, many manufacturers are emphasizing HDR support, HDR content decoding is the simplest, followed by the panel brightness to reach a certain peak, and finally the content support. The popularity of HDR content still has a long way to go. At least, HDR technology is still very rare. Even if your TV HDR has water, you don’t have to worry about it.
sound:

According to the official list of parameters, the 65-inch millet TV 4A has only one pair of built-in stereo speakers. The power of 6W can only be heard, and the sound is very thin when Dolby sound isn't turned on. After opening it slightly improved, but it is only a passing level. For sound effects, please pay attention to the external professional speakers and amplifier.
System experience:
There is a small window in the upper left corner of the home page where you can quickly switch signal sources. It is of great help to users who have access to several signal inputs at the same time on the television (eg, cable set-top boxes, home consoles, Blu-ray players, or TV boxes).
Millet TV's UI is absolutely the leader in domestic Internet TV. Whether it is from interface design, operation logic, and reaction speed, it is very difficult to spurt. The column classification and content arrangement are relatively reasonable.
Non-members can only look at standard definition, high-definition, and use a 4K TV to look at the high-definition resources of a dog into a dog. Hehe...
voice assistant:
Due to the hardware limitations of the TV itself, using a remote control to enter text can be very difficult. It is very troublesome to press a remote controller only a dozen times to hit a word. This "artificial voice version" of the voice assistant can quickly find content, but also guide users to further subdivide the results, it is indeed more convenient than pressing and down on the remote control.
summary:
Due to the lack of transparency in the industry and the strong flicker power of manufacturers, various concepts have emerged one after another. Consumers are routinely misguided. Before you buy a TV, it's best to make a comparison of actual experience and competitive products (there is no harm without comparison). This principle also applies to this millet TV 4A, rough appearance but the system is doing well, quality, algorithm law, content is rich but to open members to ensure a better experience, as the voice assistant is icing on the cake, the budget is limited You can also choose the normal version.
