Redmi TV 70 Review: A 70-inch 4K TV With Very Affordable For $478.34


By the end of July this year, the redmi was less than 8 months old, and we saw that the category of TV has been covered by it. The release of the 70-inch version of Redmi TV has also marked the launch of Redmi. A full-class war against friends.

I have to mention the background, that is, this year, mobile phone brands are concentrated on TV cross-border. Except for redmi, there are currently known manufacturers such as Huawei, Glory, and OnePlus, which have already launched or are about to launch related products. Thanks to Xiaomi TV in this field has been cross-border and explored for six years, redmi can directly rely on the technology of Xiaomi TV, no need to go the road again.

We also saw that Redmi TV continues the ultimate price-performance positioning of mobile phone brands, and the price of 70-inch giant-screen TV is lowered to 3,399 yuan (price is 3,799 yuan, the first sale is 3,399 yuan), which is more than the current mainstream. The 55-inch TV is much cheaper.

Such a TV, how to achieve a low price of 3399 yuan under the premise of 70 inches? Is the actual screen quality and experience guaranteed?

Design & Appearance

Look at the appearance first, Redmi TV up to 70 inches of the display area is not currently mainstream. However, if you are not standing in front of it, you may not feel it intuitively.

The author found a colleague with a height of 172cm. After opening his arms, it is difficult to hold a Redmi TV with a width of 1583.8mm. You can feel the size of the 70-inch giant screen. Before you buy this TV, you need to consider whether the TV cabinet in your home needs to be lengthened. In addition, when handling or moving, more than two people are required to handle it. It is not easy to carry or adjust the position, and at least two people are required.

Constrained by cost, in addition to the base, the Redmi TV body parts are basically made of plastic. However, in terms of the front of the fuselage, the cheap feeling of plastic is not seen, and the piano lacquering process is applied to the plastic frame without losing the sense of quality. As seen earlier, the border width of the Redmi TV is not too narrow, but it is better placed under the 70-inch display, and the standard frame is not conspicuous.

The back cover is still black, but there is no blessing of the piano paint process, which is much rougher than the front. However, when using the TV in daily life, it is rare to go around the TV to watch it, and it is enough to look at the positive value. The base is the same as the Xiaomi brand TV that we have used before. It is fixed with four screws (two screws on each side).

The body interface of Redmi TV is still very rich. Specifically, it has 3 HDMI (including one ARC), 1 AV interface, 1 analog signal DTMB, 2 USB interfaces, 1 Ethernet interface, and audio. Output S/PDIF1. The Redmi TV comes standard with a 12-key Bluetooth voice remote control with a short keystroke.

Quality of the picture

Even though smart TV has created a variety of fresh functions as a wave of new selling points today, the mainstream view still believes that buying a TV is to buy a display screen. The size and quality of the TV is an important aspect that everyone cares most.

Redmi TV has a 70-inch large screen with 4K (3840×2160) screen resolution, a 6th generation image quality engine, and the processor supports HDR decoding. The 70-inch giant screen we can see at a glance, no need to rumor. So what is the picture quality of this screen? No detailed parameters were displayed in the conference or on its official website, so we did the following tests.

Here we used the Red Spider Color Corrector to partially test the screen quality of the Redmi TV. You can see the specific information such as screen gamut, brightness, and contrast that have not been published by the Redmi official.

4K graphics effect test

This test will be carried out through the professional test tool “4K resolution test chart”, which is based on the TV picture quality display principle, for 4K TV to carry out all-round multi-angle customization, by experts in the field – China Photographers Association, Produced by Mr. Qian Yuankai, member of the National Photographic Machinery Standardization Technical Committee.

The above is the test tool as a whole, and the three pictures are tested on the TV screen from three aspects: definition, color accuracy, and wide viewing angle. The test picture has two arrows, red and blue, with the blue color of 1080P and red color of 4K. Next, our test process can ignore the blue arrow to see if Redmi TV has reached the test requirements for image text annotation.

We follow the process to test the clarity first. Looking at the screenshot, you can see that all the four lines of Chinese characters and letters in the figure can be clearly identified and displayed, and the effect is also clear and visible. In general, the display device with poor performance will lose the text details in the small Chinese characters/letters. Redmi TV can pass the test.

This is a color image test to observe the color distribution map and the chromatic sphere diagram of our screenshots. It can be found that the color saturation of the test results is better, and there is no jump or easy step of the previous equipment. Ability to display rich colors in layers.

Next separately:

In the color distribution map, the display effect of Redmi rice TV can obviously meet the requirements of text labeling, and the color distribution areas such as R, G, B, Y, C, M and so on accurately display the ideal shape, and the color map is also better. Evenly soft transition.

Look at the test of the viewing angle. In this test project, Redmi TV shows a relatively good viewing angle. The official did not disclose the specific parameters and information of the TV panel. It can be inferred that it is an IPS panel or a VA panel. No matter which of the above panels is developed, there is basically no concern about the viewing angle.

We also performed a grayscale test on Redmi TV, which represents the hierarchical level of brightness from the darkest to the brightest. The level and detail of the month are rich, and the effect that can be presented is more delicate. Let’s take a look, almost every level of gray is distinguishable, and there is no jump.

4K HDR video

Here we have found a 4K HDR source. However, it should be noted that in this price range, do not expect any 4K HDR display playback, especially for the Redmi TV, which is the most cost-effective TV product.

Redmi TV is only a processor that supports HDR video playback, and its panel does not restore all the display effects of HDR video. As a 70-inch giant screen TV that can be used in more than 3,000 pieces, we should not have an unrealistic luxury. In order to pursue the ideal 4K HDR playback effect, it is best to start with a TV device with dynamic partition backlight technology, which is completely non-existent in the current price-priced, even more, expensive 70-inch TV.

In other words, Redmi TV can only decode and play the processor on 4K HDR video, and can’t show its effect on the panel side, that is, “can not broadcast”. This approach is very positive – support HDR decoding can play more sources, if you accidentally download the HDR source, you can still play normally, without having to see the full screen snowflake or receiving the undecoded tips in vain.

In terms of video compatibility and decoding, Redmi TV also supports H.264, Real, MPEG1/2/4, etc., reaching the current mainstream level. With the Cortex A53 quad-core processor and the performance output of the Mali-450, the entire playback process is fast and smooth, and it can meet the daily viewing needs of the family. Of course, if you have to sit within 2 meters, I will try it for you. When the viewing distance is less than 2 meters, the viewing experience is not as comfortable as 2 meters, and the effect will be compromised when playing non-HD movies.

User Experience

Xiaomi first entered the Internet TV industry in 2013. In just a few years, it achieved 8.4 million units shipped in 2018. It is far ahead of the traditional leaders of Hisense, Changhong, and Skyworth.

The exploration and accumulation in the six years are clearing the obstacles for the new Redmi TV. After doing the homework, relying on the already mature and leading millet TV, Redmi TV has gained a lot of energy from the former. Obviously, the basic disk of “Daddy” Xiaomi TV started up – the easy-to-use interaction brought by the convenient operating system. Redmi TV uses the PatchWall artificial intelligence voice TV system and has built-in Xiaomi mobile phone users, especially the small love students who are familiar with rice noodles.


PatchWall is a UI like a waterfall. We can press the “down” button on the remote control and the content on the TV screen will scroll down and update. Even if you haven’t used Xiaomi TV, you still feel that this puzzle wall is very familiar because it was widely imitated by other TV manufacturers after it was first launched.

If it is a Xiaomi mobile phone user, I am very familiar with Xiao Ai’s classmates. On Redmi TV, we can wake up the TV’s built-in little love classmates through the remote control and issue various commands including voice commands.

Just like on the mobile phone and the physical speaker, we can also call out various functions on the TV through the voice button on the remote control, such as the search for movies, check the weather, open the application, character recognition, volume control, encyclopedia, etc.

We can share a Xiaomi account with the Mijia APP on the mobile phone so that the TV can be used as a mobile phone to control the smart device. Through Redmi TV, we can also control a variety of Mijia smart devices in the home, which can be said to be another control center outside the mobile phone. Xiaomi was good at “adding” when he first made a mobile phone and integrated various resources. Nowadays, one of the great advantages of Internet TV is that it is good at integrating resources.

Today, this is especially true in Redmi TV. At present, the main content partners of Xiaomi TV are iQiyi, Tencent, Youku, Sohu Video, PPTV, Mango, Future TV, China Digital, BesTV, bilibili and many other content platforms. Since Xiaomi itself does not make content, it does not compete with the content side, which is one of the reasons why it can aggregate and maintain such a large content ecology.

Screening experience

In the past, the author’s experience evaluation of traditional TV has a deep feeling of the trouble of using the traditional TV screencasting function: either an external TV box, or a third-party screencasting software, or the original screencasting function of the video software.

Among the many functions of Redmi TV, the fast projection is quite practical. Regardless of the current limited use of Xiaomi/Redmi and Xiaomi/Redmi notebook users, we hope that Xiaomi will further expand the scope of projection equipment.

The QR code has been mosaiced by the author. The steps to connect are simple. Even for the first connection, you only need to scan the code to achieve fast projection.

It is worth mentioning here that if you want to display common files such as Docx, xlsx, ppt, pdf, etc., you don’t need to cast a screen, Redmi TV can read and display, for enterprises, if you put a Redmi TV in the conference room In the future, internal presentations and meetings will basically not require a computer.

More than Redmi TV is currently all mobile phone interface projection smart TV is inspired by Miracast mirror projection mode, the same proportion of the mobile phone, the direction of the image is completely projected onto the TV, thus leaving black sides on both sides.

Power Consumption Test

Next, the author makes a simple test on the power consumption of some users who are more concerned about the interests of Redmi TV.


From these days, the Redmi TV’s 70-inch experience, in addition to the 3,399 yuan can get the very low price and 70-inch giant screen and other features, other aspects of the law-abiding, in fact, there is no too prominent highlights, Belongs to the mainstream performance of this price.

However, for most of our families who advocate pragmatism, the most prominent highlight of the 3,000-yuan giant screen overshadows everything. In particular, it can maintain the same level of the mainstream in other aspects, while making the screen 70 inches, it is even more painful.

At this point, after the actual experience, Redmi TV 70-inch dispelled the concerns of the author and many friends, for example, the quality of the giant screen TV will not be too good? Will the operation be stuck? After the actual experience, I found that these are all worrying.

After our experience test, Redmi TV has an obvious advantage of the giant screen (more than 60% larger than the mainstream 55-inch). It is quite satisfactory in terms of image quality, close to 100% SRGB color gamut test results and just over 300 nits. The highest brightness is currently seen in the new 4K resolution smart TV products above 4,000 yuan.

The appearance of the fuselage is limited to the cost (after all, 70-inch giant screen is expensive), and a large proportion of plastic is used, but it is good to have a piano paint process on the front of the TV, so if you don’t often show it back, there will be no Feel free, this can be assured .

That’s it, under the premise of 70-inch entry into the 3000-yuan file, many of Redmi’s red-meter TVs don’t seem too glamorous and can be ignored. This is the ultimate cost-effective giant screen.

In addition to the large enough screen and the mainstream enough quality, thanks to the dual-brand strategy, redmi TV can rely on the technology of Xiaomi TV, we see a rapid investment in this redmi TV first Screen connection and other gameplay, as well as the compact content base of the Xiaomi brand, the classic Xiaomi TV system is a plus .

The emergence of Redmi TV 70-inch TV marks the first time that the 70-inch giant screen has been pulled into the 3,000-yuan era. It has also become a giant screen popularizer. Let us choose the larger screen with the same budget as the 55-inch TV. The system is better to use the TV, which was unimaginable in the past. If the budget is just right, and do not care about some of the details mentioned by the author, then buy and buy is right.
