In fact, from the name we can roughly determine that 4K TV (also called UHD Ultra HDTV) is 4 times as much as the traditional 1080p TV in resolution, and the number of pixels has been increased from 2 million to 8 million. This means that 4K will bring more detailed display details, more realistic textures, and smoother smoothness. And this is just a beginning, including broadcast TV service providers, can improve the frame rate and bring better contrast and a wider color gamut.
What is IPS (plane conversion) hard screen 4K in the end?
First of all, the panel is the key to the TV display and determines the quality of the TV. The IPS panels used by LG are known for their professional quality and durability in the industry. Even in the room to freely choose the viewing angle, you can enjoy a professional-level color experience.
1, a wide perspective. It also maintains virtually undistorted color performance and contrast at different viewing angles. Allows you to enjoy high-quality picture performance even when viewing from a larger angle.
2, vivid colors. The world's leading professional panel, IPS panel display vivid 4K picture quality, breaking the previous television performance. The broadcasting, pharmaceutical and other industries have chosen it because of their extremely high demands on the accuracy of the picture. The IPS hard screen 4K panel has improved the quality and accuracy standards of digital displays.
3, stable screen. Lightly hit and feel quality. Due to its unique structure, the IPS hard screen 4K panel recovers faster than normal panels after striking. Just one tap, you can feel its stability and sturdiness.
4, clear and smooth motion picture. In the motion picture performance, IPS hard screen has obvious advantages, almost no smear picture allows you to enjoy a more clear visual pleasure.
When it comes to hard screens, we need to talk about soft screens. The identification between the two is mainly to see that there are no water lines on the touch screen, and there is no IPS hard screen, otherwise it is a soft screen.
Today we look at the protagonist of this test: Millet TV 360-inch, just now has a simple science knowledge of the screen basics, then we start with the most basic screen test.
Millet TV 3 60-inch official claims to use the original LG 4K screen, so in the end is not the case?
One, 4k picture quality actual combat
Millet TV 3 60-inch is using LG original 60-inch genuine 4K screen resolution of 38402160, is 4 times the full HD (1920 x 1080 resolution), about 9 times the high-definition (1280 x 720 resolution) .
In this 4K image quality test, we used a professional 4K TV test chart, and through several pictures, we can easily see the performance of Millet TV's 60-inch resolution, resolution, color, and tone levels. This time we mainly include three aspects of resolution testing, color testing, and tone level testing to see if the Millet TV 360-inch system can stand the test.

4k TV resolution test chart
In the resolution test chart, Millet TV 3 60 inches performance is quite good, whether it is text, or lines are very clear, 4K can distinguish the first of the finest, Full HD can only identify the third article, Through Figure 1, we can see that Millet TV 3 60-inch large screen, 4K resolution will be demonstrated most vividly.
4k TV color performance and visual angle test chart
4k TV color performance and viewing angle test chart, 24 color blocks are selected according to the SHB color system hue angle every 15 degrees a color, saturation and brightness are taken 100%, the more saturated the color gamut means that the display color gamut is wider If the colors of adjacent patches are too close to each other, that is, there is a parallel-order phenomenon, it means that there is an error in the color reproduction.
In the lower left corner of the color map, the closer the boundary between G, B, R, Y, C, and M is to the triangle, the more accurate the color reproduction is. The nine spheres on the right show the performance of color scales. The light and dark should be uniform and soft. Millet TV 3 60 inches in the overall color performance is very natural, saturated.
4k TV tone level restore test chart
The 4K TV tone level is an important indicator for displaying image grades. The light and dark parts of the Xiaomi TV 3's 60-inch display should be able to be displayed on the test chart 252 and 7 levels. Level distribution maps and sphere diagrams should be able to display levels at all levels. And the transition from black to white is very natural.
4k test chart
Next, we tested the quality of the next screen to see if there was any light leakage. In the dark environment, the test results showed that there was no light spot on the 60-inch screen of Xiaomi TV, and there was no light leakage.
Second, 4K combat
Before 4K combat, we need to understand the 60-inch local decoding capability of Xiaomi TV 3. It supports H.265/H.264 hard decoding, built-in Mi-Player full format player, support RM, FLV, MOV, AVI, MKV, TS, MP4 and all mainstream formats, Xiao Bian tested these mainstream formats are perfectly supported, playing smoothly.
Play "Warcraft" with your own player
Here specifically pointed out that the millet TV has obtained the right to broadcast the European Cup, directly embedded in the UI, directly through the remote control to the lower menu and pop up the previous events
After tapping, the device needs to perform a simple authentication and jump to the lower menu
Xiao Bian is a typical England football fan and naturally chose England’s game video
Loading speed is very fast, clear and smooth pictures without any drag and delay, while Xiao Bian choose to watch the program, and did not make any settings, in full accordance with the millet TV 360-inch default mode of viewing.
In order to better demonstrate its 4K decoding and playback capabilities, Xiaobian specifically downloaded 17G source (Fortunately, I am 100Mbps broadband)
During the entire download process, Xiaobian watched the 60-inch European TV with the European Cup resources downloaded. Before the test, Xiaobian made a simple setting for the Xiaomi TV 360-inch.
Motion compensation is the default "off" status, click "Open"
Simultaneous 4K film source download and Millet TV 3 60 inches comes with European Cup resources to watch
Here it can be clearly seen that the author has six terminals in the shared network, and download, watch, games and other conventional video operations, millet TV 3 60 inches at the same time in the video playback, the following figure is clearly seen, there is no The phenomenon of any smearing and staving, in the conventional viewing distance, the clarity is very high, the motion compensation function is turned on, and the motion picture is decoded.
In the long wait, the download of the 4K source of 17G is completed. The author copies it to the mobile hard disk, and the operation interface pops up directly to “Discover the U disk†and directly click to play the 4K source.
Third, the hardware configuration
Millet TV 3 60-inch using Mstar6A928 Cortex-A17 quad-core processor 1.4GHz CPU, 2GBDDR3 three-channel memory, 8GBeMMC5.0 large flash memory, this hardware configuration, personal feel is already high, I do not have to worry about the problem of Caton Now.
Using original LG 4K hard screen: I press hard to press
Clearly seeing my fingerprints on the screen (嘎嘎) seems hard enough
In order to verify the actual performance of Xiaomi TV 3 60 inches, Xiao Bian downloaded and installed Ann Bunny TV test software to see its overall data performance.
Xiao Bian directly downloaded the good security Bunny TV evaluation into the U disk prepared in advance, the smooth installation. Millet TV 3 60 inches direct prompt discovery U disk, fool-style operation is simple and quick
Installed directly click open, smoothly loading security Bunny evaluation TV, loading screen is still quite taste
Directly into the testing process, during the entire testing process, An Tutu tests the TV from four dimensions: 3D RAM CPU UX respectively.
After more than ten minutes of waiting, the final evaluation data is much higher than the author's expectations.
In the actual performance of the test 3D, millet TV 3 60 inches no obvious Caton phenomenon, the resolution of the test screen has been maintained at 1080P resolution
Millet TV 3 60-inch final score performance: 31691
Completely tested according to Millet TV's 60-inch initial default, without any third-party software optimization
Fourth, the system UI
Millet TV 3 60 inches still use its high quality MIUI system in the system, but still work hard in details to give users a better experience.
The entire interface looks very simple and easy to operate. Compared with the Xiaomi TV 2S, the TV and online movies have been reduced, and the millet store, watch history, and video news have been added below. The far right side is the system's own application, and there are some downloaded third-party software applications.
There are more and more things in Xiaomi Mall, and the ecological chain products cover almost all current hot products.
Fifth, the host disassembles
Millet TV 3 60 inches with split design, TV and stereo separate. It is a highlight of the next generation of Xiaomi TV's 60-inch TV. The hi-fi HiFi audio system and the immersive concert and theater experience are all a plus for the 60-inch 360-inch TV. Do you want to know how such a sound system is designed?
Three sets of HIDMI interfaces, two sets of USB interfaces (please note that millet sound is differentiated on the USB interface, and the distinction between USB2.0 and USB3.0 is marked)
MI PORT interface is connected with the millet TV
Networ directly involved in the RJ45 network cable
AV input input interface
Audio Output to Woofer
Audio output interface Antenna Needless to say, if you want to connect cable TV, you can insert it directly.
The fixed locking interface on both sides of the audio is a convenient place for hanging the audio to the wall. The audio can be hung on the wall. There are two sets of pads in the lower half of the audio, and can also be placed directly on the floor.
The audio front is the TV's operation panel, using the traditional button operation mode, where the millet sound does not use LCD or touchpad, Xiao Bian still prefers this mode of operation. (Note: Please note that the red umbrella on the edge, do not let the sound water)
Xiao Bian took out the sound of the 1st generation of millet TVs and compared them. There are many major differences in the size specifications. The operation surface of the 1st generation product is changed to the side of the sound, and the operation mode of the touch panel is used.
In the external interface, you can see the obvious difference, there is basically no expansion capability, a generation of products can only be honest to be a speaker.
Because the author is a typical Virgo, in order to ensure the sound is not perfect physical dismantling, but in order to show the internal structure of the sound, Xiao Bian collected a very detailed dismantling map.
Dismantling icon:
Next is the dismantling of the host and audio parts, first to a front view
The host and audio are all made of metal and the screw holes are underneath
The process of dismantling the screws is the same as that of the screen, but the details are explained
After the screws are removed, they cannot be opened immediately because there is a snap structure inside and we need to use our prepared fins
Slowly open the upper cover
This is the complete structure after removing the cover, you can see the sound separated on both sides, the middle part is the motherboard chip
Let's look at the control chip on the cover button
To see the part of the motherboard, still use a small screwdriver to disassemble several screws
This is the complete motherboard part
We look at the details with a magnifying glass. The first big chip is the built-in MStar 6A928 TV processor, and the built-in Samsung memory chip next to it.
Let's look at the details on the motherboard
The dismantling continues, now is the part of the audio removed
Then we can remove the motherboard chip, a variety of interfaces and chips highly integrated, the layout is quite reasonable
You can see the built-in 4 2.5-inch bass speakers and 2 20-ball dome tweeters. Built-in Dolby Dolby Audio technology, support for virtual surround, bass boost, dialogue enhancement, automatic volume balance
This is all the accessories after the host dismantling
While testing its sound, listening to high-pitched mid-weight bass
Treble playback exceeds the limits of human ears, and bass reproduction is flexible.
Six, evaluation summary
For millet TV 3, only the use of its 60-inch LG 4k screen to see the millet's intentions on this product, high color gamut coverage, visual experience without smear is to let Xiaobian feel smooth The dripping, viewing angles with no difference in color and contrast are also taken into consideration of the psychological demands of Xiao Bian's hyperactivity disorder consumers. It is evident that starting from Xiaomi TV 2S, this Internet company has been telling its own way. attitude.
