If we say that last year OPPO was still testing the waters, setting the tone and promoting in the field of smart TVs, then this year it has clearly accelerated its pace of active offense. The direct evidence is the launch of the K9 series of products. While ensuring that product prices are becoming more and more affordable, it has also greatly improved the underlying competitiveness of TVs, such as audio and video performance. In addition, it has decisively integrated more elements of the Internet of Things, making TVs and mobile phones a whole.

It is no exaggeration to say that because all of them are aggressively attacking the interconnection function of their smart TV products, the decisive factor affecting user purchases in the future may be due to the brand of the mobile phone in hand. The reason is simple, the driving force of large-screen TVs has shifted from themselves to mobile phones. Whether it is content or control, it is an unstoppable reality that TVs have become an extension of small-screen mobile phones.

This year, OPPO has become the mobile phone brand with the highest market share in China. Taking this opportunity to launch the affordable and high-end K9 series new products, it naturally became the best opportunity to promote OPPO's concept of the Internet of Everything. As the most important hub of home entertainment, it is completely in line with market logic to take the promotional position of OPPO as the TV. For users, this may also mean that the best window for purchase has opened - OPPO did not intend to make money from TV this time. What it needs is more users who are connected to everything, so it has the K9, a high-quality and low-priced product. If you don't buy it now, when will you?

From the perspective of the market environment, launching the K9 series of TVs is an inevitable choice for OPPO. So, from the perspective of product strength, can it really withstand the market's picky test? Everything ultimately depends on the product. Now, let's take a look at the strength of this OPPO smart TV K9 65-inch.

Appearance: high screen-to-body ratio, complete interfaces

The appearance design of TV has always been a nightmare for designers, especially in today's era of high screen-to-body ratio, because the room left for them to play is too small, so small that it is almost impossible to make any changes.

Perhaps it is precisely because of this that, adhering to the concept that no design is the best design, the screen-to-body ratio of the OPPO Smart TV K9 65-inch has reached 95.82% in one fell swoop. The extremely narrow frame even has to protrude a piece at the bottom to accommodate the "OPPO" logo. Apart from this, the entire frame is nothing else. The benefits of this design are obvious. While bringing users a positive and minimalist visual experience, it also allows users to achieve a cinema-level leap in viewing experience.

On the back of the body, the OPPO Smart TV K9 65-inch is generously equipped with three HDMI 2.1 ports and two USB 2.0 ports. Digital TV, Ethernet and other interfaces are also readily available. It is enough to meet daily entertainment needs such as playing games and watching movies.

Although gaming is not the biggest selling point of the OPPO Smart TV K9 65-inch, the HDMI 2.1 interface ensures that it will not be outdated in the next five years. Combined with the 4K 60Hz refresh rate screen, it is enough to play next-generation console games such as PS5.

A wide color gamut 4K screen that restores the most realistic colors

Picture quality performance is the physical cornerstone that OPPO smart TV has been pursuing since its inception. The previously launched S1 and R1 series have picture quality and color that are among the best in the same price range.

OPPO Smart TV K9 65-inch is no exception, it uses a 4K 60Hz LCD screen. Opening the 4K TV resolution test chart, we can see that the outline of the small characters in the upper left corner is still clear, the details of the color blocks below can also be displayed correctly, and there is no obvious gradation in the color block area in the upper left corner. The excellent color performance overflows the screen.

In the video test, the OPPO Smart TV K9 65-inch also truly restored the colors of different ingredients, the textures and wrinkles were clearly reflected, and the entire video playback process was smooth and without ghosting.

Note: The screenshots in this article were taken with an iPhone 12, 0.7x zoom, and the rest of the settings were default

What is worth mentioning about the OPPO Smart TV K9 65-inch is that it supports 93% DCI-P3 wide color gamut. This screen can perfectly present the 1.07 billion colors that the human eye can perceive.

From the screen shots, we can see that even in scenes with more complex colors, the color levels and details of the picture are clearly visible, and the transitions between colors appear soft and natural.

DCI-P3 is a wide color gamut standard launched by the American film industry. Devices that meet this standard can truly restore the colors to be presented in the film, especially red and green, thereby bringing a more realistic display effect.

From the actual photos, we can see that on the OPPO Smart TV K9 65-inch, the subtle differences in the "green" of the two trees are finely reflected, and even the red of the car and motorcycle on the far left of the picture can be displayed brightly and strongly.

OPPO Smart TV K9 65-inch also has a high color accuracy of DeltaE<2. Delta E is a standard calculation metric that is closely related to the difference in visual judgment that humans can make between two perceived colors.

Generally speaking, the lower the Delta E number, the closer the color displayed by the monitor is to the original color of the input. In the picture below, the skin color of the characters, the reflection of the musical instruments, and the unique texture of the metal are all very close to what the naked eye sees.

HDR 10+ certification, the ticket to high-quality TVs

In order to obtain a better viewing experience, HDR has become an indispensable function of display devices. HDR stands for High Dynamic Range, which is simply a technology that improves the brightness and contrast of images. It can make the details of dark areas brighter, dark areas darker, and enrich more details and colors, making the image present a better effect.

As a smart TV with HDR10+ professional certification at a mid-range price, the market competitiveness of OPPO Smart TV K9 65-inch is self-evident. Moreover, when general TV products say they support HDR10+, they only refer to decoding, which is not the same as the OPPO Smart TV K9 65-inch that supports HDR10+ video effect display.

Here is a brief introduction. HDR10 is not the same evaluation system as the common HDR400/600. The former is mainly for TVs, while the latter is used to evaluate computer monitors. HDR10+ is a standard developed on the basis of HDR10. It supports frame-by-frame brightness adjustment, enhances the depth and realism of the screen image, and presents a brighter or deeper picture effect.

In actual use, the OPPO Smart TV K9 65-inch, which supports HDR10+, can present a natural, real and vivid effect when playing movies. As can be seen from the picture below, the picture has excellent depth, bright colors, and obvious contrast between light and dark.

In this screenshot with a relatively dark overall tone, we can still see the outline of the meteor in the picture, especially in the lower left half of the picture, which is clearer.

The third episode of the eighth season of the TV series "Game of Thrones" is dim, making it a famous "HDR detector". Using the OPPO Smart TV K9 65-inch to play it, we can find that even in dark scenes, the outline of each character is still clearly discernible.

Because HDR10+ significantly improves picture quality, it has become the entry ticket to high-definition TVs. If you want to pursue a high-definition experience, you must look for the HDR10+ logo.

Professional Blu-ray team ensures exquisite viewing experience

Mentioning OPPO, most people's first reaction is mobile phones. In fact, OPPO is even more outstanding in the field of Blu-ray players, and "Little Leo" Leonardo Dicaprio is a loyal fan of it.

OPPO has been at the forefront of the industry since it launched its first Blu-ray player in 2008. After entering the smart TV field, OPPO also brought in its experience in Blu-ray tuning.

OPPO Smart TV K9 65-inch uses amazing ultra-clear processing technology, making the picture details richer and the display effect even better.

In the screenshots, details such as the person's hair and pet's fur are well displayed, and the person's skin color and pet's fur color also appear very natural.

In the picture below, the left and right arms of the character show different colors due to the different angles of light exposure, and this detail is also accurately displayed. The face that is not directly exposed to light (especially the right face) retains a relatively realistic skin color, which shows the profound skills of OPPO Blue Light Team in image analysis and color management.

30W Dolby audio speakers create a shocking auditory experience

Without sound, no matter how good the show is, it won’t come out. In terms of sound, the OPPO Smart TV K9 65-inch is equipped with dual 15W speakers with a frequency response range of 150Hz~15KHz. Compared with other products of the same price, its sound field is wider, the sound is louder, and the treble is crisper and clearer.

In addition, OPPO Smart TV K9 65-inch also supports Dolby sound effects, which can achieve 3D surround sound effects, bringing more sound details and a more shocking auditory experience.

Overall, in terms of hardware, with its 4K HDR10+ display effect with wide color gamut and high color accuracy, coupled with a 30W high-power speaker, the OPPO Smart TV K9 65-inch has successfully built an audio-visual experience that is priced at the high end of 10,000 yuan. This is in line with its market strategy of increasing performance and lowering prices, and also brings users a leapfrog value experience.

ColorOS TV brings smooth control

Smartphone manufacturers generally pay great attention to system construction when producing smart TVs. The OPPO Smart TV K9 65-inch is equipped with the new ColorOS TV 2.0 system, and the 1080P full HD UI interface makes people want to continue using it at first sight.

In fact, because this system continues the user habits of OPPO mobile phones' borderless UI style and global drop-down menu, it can also realize functions such as quick switching of applications and adjusting image brightness, maintaining the logical unity of smartphone and smart TV control.

Of course, behind this smooth control, performance redundancy is the fundamental guarantee. 65-inch smart TVs of the same price often use 1.5GB RAM + 8GB ROM configuration, while OPPO Smart TV K9 65-inch uses 2GB RAM + 16GB ROM large memory, with the same configuration leading the same price quad-core A73 architecture MT9652 chip, so that users' operation fluency has reached a new level. During the test, there was basically no screen freeze.

In terms of film and television resources, the OPPO Smart TV K9 65-inch brings together film and television resources from the four major mainstream video websites, Tencent, iQiyi, Mango TV, and Youku, and also adds short video and sports channels, enough to meet the family's diverse entertainment needs.

The Internet of Everything Creates an Intelligent Hub

As a smart TV, interaction is an important part of the system. OPPO Smart TV K9 65-inch has a built-in smart voice assistant "Xiaobu". During the test, Xiaobu's control in voice wake-up, smart home control and other aspects was very good.

Of course, the most noteworthy aspect of the OPPO Smart TV K9 65-inch is its interaction with mobile phones.

OPPO mobile phone can become an excellent remote control for it, realizing functions such as quick screen casting with one click to play content, quick sharing of wonderful moments by taking screenshots, using the mobile phone keyboard to assist in text input, lowering the TV volume by sensing incoming calls, syncing photos shared from mobile phone to TV cloud album, setting TV screen saver, etc., making interactive connection and control of TV simpler and more convenient.

Specifically, OPPO phones using ColorOS 11.0 or above and supporting NFC can realize the One-Touch Flash Cast 2.0 function with the OPPO Smart TV K9 65-inch. Whether listening to music or watching videos on the phone, just touch the phone and the remote control to automatically mirror the screen.

Other Android phones can also cast screens on the OPPO Smart TV K9 65-inch through the standard screen casting protocol Miracast, and Apple system phones can cast screens on the OPPO Smart TV K9 65-inch through the airplay screen casting protocol.

For users who have not purchased TV membership of the video website, they can play videos on the mobile client and cast the screen to the TV. This saves a membership fee and still ensures the same excellent viewing experience.

In addition, the OPPO Smart TV K9 65-inch also supports OPPO's industry- first four-way screen projection function, which is very suitable for entertainment when friends get together.

Other brands of mobile phones can also interact with it via NFC

OPPO Smart TV K9 65-inch can also serve as a smart home hub, supporting smart home information, control and status display. In addition, it can also control the TV, manage children's mode, and view smart home status in real time through smart home mobile phone applications.

It is worth mentioning that the OPPO Smart TV K9 65-inch also retains the Xiaotiancai customization function, which supports video calls and voice calls with Xiaotiancai watches, so that the whole family can keep track of their children's movements at any time.
