First of all, I am very grateful to TCL and ZAKER technology channel for providing the opportunity for this evaluation. I experienced TCL's latest flagship TV XESS X3 55-inch curved TV for the first time. Since it was a TV gamer for more than 10 years, I had a lot of purchases. TVs of different brands and different prices, because the development of the domestic TV industry is late, there is a certainty in the thinking, that is, many domestic TVs are inferior to foreign brands, but this time they use TCL XESS X3 screens to use international brands. The new technology, but also a great breakthrough in the sound quality, so I was thinking about what level of domestic TV is now million yuan?
Purchase experience:
Led TV as a display device, the most important thing is to see the display effect, than the sound, network function is much more important. The display effect depends mainly on three points: the quality of the liquid crystal panel, backlight tube, and the order of arrangement, and the circuit board is the color processing circuit.
LCD panel: Now the LCD panel is mainly Samsung, LG, Fujitsu and other manufacturers (of course there are Sharp), when buying we can consult shopping guide or view the product description to see which panel is used. Then to start monitoring, one is to see the brightness of the LCD, you can set through the menu, because the LCD TV time to see the screen as a whole will darken, this will certainly affect the future of viewing. The second is the LCD screen has no dead pixels, or dark spots, the test method is very simple, with a few solid-color photos displayed on the LCD screen, you can observe there are no dead pixels. If anything, though, it does not affect the viewing effect, but buying is a good idea.
Backlight tube quality and arrangement order: To inquire about which backlight tube is used, Philips is generally used in the market. The other is that everyone should look at the order of the backlight tubes. Commonly used in the market is a cylindrical arrangement, but this arrangement is not uniform brightness, light energy utilization is not high, the backlight is prone to problems after a long time, the performance is flash ah, the screen yin and Yang screen, one side light Dark side 1; high-end TVs are arranged in U-tubes, so that the brightness is even and life is longer.
Circuit board that is the color processing circuit: This is a university asked, now on the market the most advanced technology is SONY's Motionflow XR engine, LG's XD engine, TCL's QUHD engine, it is recommended that you can buy before you can go to the physical store to compare.
Second, appearance:
TCL this TV because of the use of curved surface, so everyone needs to pay attention to the installation, can not put the screen down, because the uneven force will cause the TV screen crack, when moving can only be vertical up; It is also important to note that the screen cannot be wiped with a damp cloth or alcohol, as the screen of the television is generally coated with a layer of paint. If the coating is damaged, the screen of a television is also wasted.
The XESS X3 supports suspension or desktop placement. It is also easy to install. Use a Phillips screwdriver to secure the base.
The base of the X3 is L-shaped in its entirety, straight down from the back, and then spreads out from the middle to the ends, making it very stable.
Materials, the use of aluminum alloy material, gold, high hardness, weight 500g, corners have also been polished.
The X3 curved screen uses 4000R curvature, because the smaller the value of the curvature is, the greater the bending degree is. The 4000R is most suitable for viewing distance of the family, because this curvature can make the TV completely reach the eyes at every point. Distance, stronger sense of presence.
Due to the high proportion of screens in the X3, although it is a 55-inch television, the space occupied by the desktop is not as much as imagined.
The screen should be inlaid on the panel of the TV. The workmanship is still excellent. There is no glitch.
The frame has also been polished similarly to the iPad, and the color has also been treated with Tyrant Gold.
TV's speakers use the industry's more popular solutions, that is, the front speakers in the screen below, like Sony, LG and other manufacturers have a similar design, X3 is about three speakers.
It is the international big-name Harman Kardon who provides technology to TCL. If you go to the local Apple Store, you can generally see the classics on the map. Harman Kardon's products can be said to be the perfect combination of color value and sound quality.
Audio configuration, the six units are independent, two sets of high school and low, so the sound is very three-dimensional display, unlike the traditional TV combo speakers have obvious common problems, is the sound field confusion, to see what movie must have an external Echo wall + subwoofer.
At the bottom of the bottom there is a TCL LOGO and a breathing standby light to alert the TV's standby status.
In addition, the embedded position of the screen is also polished, and the overall process is very particular about the price.
The X3 did not fully use the domestic popular "upper and lower convex" design, but rather the international design of the trapezoidal design, although the first half only 6.9mm, but there is a slow contraction transition from the bottom to the top.
The left side of the back is the TV's power button, with four directions, can also be used as a remote control.
For multimedia interfaces, there is a USB 2.0 and a USB 3.0 interface, three HDMI 2.0 interfaces and a network cable interface.
In addition, there are fewer and fewer antennas and AV interfaces, and you can connect home TV boxes and DVD players. Note that the audio interface is a 3.5mm/optical fiber combo style.
Is the effect after plugging in the power cord and HDMI video cable a bit messy?
Don't worry, TCL specifically provides two cover plates to receive the wire and cover the screw holes.
It means that obsessive-compulsive disorder has been cured. If the socket panel is higher than the TV interface, the line that is dragged down from the front cannot be seen.
Third, the screen:
X3 this TV screen can be said to use the best display technology of the current LED panel, that is, quantum dot technology, and the biggest difference between ordinary LED TV is that his backlight source is very different.
Quantum Dot Technology
In simple terms, whenever a crystal such as a quantum dot is stimulated by light, it emits very pure colored light. Backlights using quantum dot materials are currently the most pure color backlights. Quantum-dot TV uses the purest quantum dot light source as the backlight source, and it is a revolutionary implementation of the full color gamut display. It achieves the 1 billion colors required by HDR and restores the most realistic image colors. If you want to say the shortcomings, that is, the quantum dot display screen needs a filter layer, can not produce light directly on the surface, so the viewing angle is slightly worse than the OLED, in short, the biggest advantage of the quantum dot TV is real.
Then test the screen, because the TV is bought to see it, the picture depends on the screen LCD panel itself, backlight, and circuit driver board. Like the TCL, which uses a 4K screen and quantum dot backlight, it has to test his actual performance.
2. Bad spots, dark spots, bright spots
First test the bad spots, we can go to the application store to download some screen detection software, after their own four-eye scanning inspection line, very happy, no winning, the LCD product control in recent years is getting better and better, Even tough curved TVs can handle it.
3. Light leakage
Leakage, the manufacturers are now learning smart, will do a layer of black screen between the screen and the border, about 1.5cm, and then adjust the size of the screen through the driver version, which solves a wide range of liquid crystal light leakage problems.
However, a small problem has also been found, that is, the brightness of the left and right corners of the television is slightly higher than in other areas.
4. Color
This aspect of the test let me shine on the X3, because I really have not seen such a natural transition of the panel,
The method of this test is very simple. A total of two places must be observed. One is that the transition between colors is unnatural, there is no obvious "white bar", and the other is that there are not many kinds of colors. Above the map, the first one is another brand TV I bought. The price is not cheap, but the number of single colors and the X3 are simply not comparable. Everyone can see the difference between the big red to the left and the other. The blue display of the TV is not natural either.
The reason why this is so powerful is that we must first understand the truth. That is the problem of color space.
If you often contact electronic products, you will often see RGB, sRGB, and NTSC. They are the standard for color. Adobe RGB is a color gamut standard introduced by Adobe; sRGB was jointly developed by Hewlett-Packard and Microsoft in 1977; NTSC is a color gamut space defined by the American Television Standards Committee. The relationship between several standards is shown in the figure below. Simply put, NTSC can describe more colors, RGB is almost completely contained in the NTSC color gamut, and sRGB is roughly only 72% of NTSC. The relationship between these color spaces can be seen on the map.
TCL X3 uses the BT.709 standard, which belongs to the gamut of sGRB. What is the concept of 157%? Converted to NTSC, it is about 113%. NTSC is more than 92% of the wide color gamut. Noble OLED TVs are also 110. About %, so the X3 this TV's color performance is really outstanding, very realistic, reaching 1.07 billion color, in line with the human eye senses.
5. Smear
Afterimages are perfect, and TCL's circuit board is still excellent.
6.HDR
Let me talk about the HDR performance of this TV.
First explain the HDR, HDR full name is High Dynamic Range, high dynamic range. Among them, the dynamic range refers to the range of brightness and contrast, and the high dynamic range has a wider range of brightness and darkness and a higher brightness contrast. It is intended to expand the contrast between the light and dark areas of the image and the details of the image. "HDR" on the mobile phone restores as much of the light and dark parts of the picture as possible to the SDR. The senses closer to the human eye.
"HDR" on television is simply used to enhance the contrast of the picture, allowing the darkest place to have a greater span from the brightest place. To take a simple example, the faint stars of the night are about 10-5th power. The brightness of the center of the sun is 10 to the 9th power, the human eye in the case of the pupil remains the same, the perceived brightness in the power of 1-5, the standard HDR is also set the same standard for the human eye, and before the TV The standard "SDR," which has been used all the time, has a brightness range of 1-10, so many details of the shadows of the TV have not been seen before.
Difference between HDR10 and Dolby Vision
The industry first has Dolby Vision, followed by HDR10. Simply speaking, HDR 10 is a relatively low-end HDR mode. It is Samsung, Sony, and LG that these home appliance manufacturers hope to save Dolby's royalties and develop standards together. However, the brightness, color, and other parameters are basically the same as those of Dolby. The biggest difference between the two is that there is a dedicated chip inside the device that supports Dolby Vision to detect the device's output capabilities (such as the brightness range, color space, etc.), and broadcast the picture that is most suitable for this device.
This TCL X3 supports HDR Dolby Vison format and is compatible with HDR10.
The HDR version of "Battle Hacksaw Ridge" has a particularly striking scene. The screen will brighten your eyes, just like you yourself on the battlefield, because HDR's backlight system exceeds 1000nits. Make the dark contrast in the scene more obvious.
In addition to the movie, I used the most popular PS4 game machine to test, and the test game selected "Uncharted 4".
7. Other aspects
The adjustable content of the image is quite numerous, such as “painting effectâ€, “backlight brightnessâ€, and “ambient light sensingâ€. For example, if the surrounding area is bright, the brightness of the TV will also increase and the contents will be more visible. Clear, at night, the brightness will become lower, protecting the human eye.
In the advanced setting, there is also the MEMC motion compensation required by the player. After the player is turned on, the algorithm for complementing the frame of the TV is excellent, and it is good to watch the ball with very little smear and no eyes. In addition, the TV's "sharpness" and "contrast" can also be adjusted according to your preferences.
Fourth, sound quality
In terms of appearance, when it comes to the X3 speakers, how about the performance?
First of all, there are two kinds of X3 sound scenes. According to the way they are placed, select the corresponding mode. If the desktop mode is used, the sound will be straight forward, and the wall will feel that the sound field is slightly downward.
And the TV has a built-in audio tri-tone adjustment button and surround sound settings. The user can adjust the corresponding mode according to his own needs. For example, he can watch the programs of the interview class, and can clear up the voice and listen to the songs. This can increase the surround sound and bass.
In addition, this TV can also be connected to the TV and the mobile phone directly through Bluetooth, turning the TV into a home Bluetooth speaker and closing the screen to listen to songs.
Triple frequency (only personal opinion)
Low frequency: The sound is clean, stable, transparent, thick and not redundant.
IF: The voice is clear and comfortable, there is a warm feeling, suitable for listening to vocals or some jazz, resolving power is not bad, there is no sense of procrastination.
High frequency: The sense of hearing is very bright. Some string performances are timely and textured, and the sound field is very wide. This completely breaks the problem of the unclear positioning of the sound field of traditional television.
Fifth, the system
First test the boot speed, from the press of the power button to operate, about 26 seconds, basically satisfied. The most important thing is that there is no advertisement on the boot, there is no advertisement on the boot, there is no advertisement on the boot, and important things are said three times!
As shown in the figure, it is the main interface UI of the X3. The Banner position on the homepage shows some of the most popular television dramas recently. For example, it is very popular in the name of “The People†and “Surgical Situationâ€. Then slide left to have a recent look and you can quickly find what you were looking at recently.
Swiping to the right means subdivided categories, such as movies, variety shows, NBA, animation, 4K movies, etc. Since TCL is deeply involved with Tencent, most TV comes with resources from Tencent.
The user can also subscribe to and sort the classification of the TV, and remove the unnecessary columns. This is still good, but the four “homepageâ€, “videoâ€, “VIPâ€, and “application†are fixed.
Resources, and the mainstream video sites, such as iQIYI, Youku basically the same, after the general theater off the assembly line, you can read through the TV, such as the recent "Kung Fu Yoga", "Wind and Waves."
The large scale of the cinema can be adjusted to 4K picture quality, and the picture quality matches the surround sound. The effect is very touching and comparable to a movie theater.
In addition, there are "Ding Theatre" and "NBA Theater" super membership programs on TV.
These two days in the NBA playoffs, you can see the daily high-definition playback and ten goals.
The quality of the video can also be selected by itself, up to 1080P Blu-ray, and a bit more than CCTV5.
The Ding Theatre is the most popular American drama and English drama at present, because these are genuine introductions and do not worry about subtitles.
Sixth, other functions
remote control
The XESS-configured remote control function is very powerful. It not only supports voice but also acts as a somatosensory mouse and plays some somatosensory games.
Only need to speak to the remote control to see the name of the movie or the name of the actor, the type of video, TV will automatically search immediately, direct content, a very quick response, I also have very good recognition of my standard Mandarin.
The function of the mouse is to turn the remote control into a mouse floating in the air. It is OK to see what the content refers directly to, and it is no longer necessary to use the navigation keys to search one by one.
App installation
However, it is regrettable that the pre-installed APP has no way to delete, and hopes to improve it later.
HDMI management
In addition, the television also provides a personalized function, such as my HDMI device is more, often do not remember what each jack is connected, this time you can set the name of the TV, do not need to use the next time The back of the TV looked.
Video playback
The basic configuration of the TV is Mstar838A, 2G memory plus 8G space. In terms of video playback, the support for the 1080P and 4K resolution movies downloaded by the users is good, and there is no problem of stalling or video synchronization.
The settings can also be used to set video subtitles, audio tracks, etc. The function is not much, but some of them have. In addition, TV also supports Airplay, DLNA and other wireless protocols, and can push content on the phone directly to the TV.
Seven, summary
Write so much, let me summarize, this XESS can see TCL's efforts, the use of the international leading quantum dot technology + 4000R curved screen, the display effect can be abroad and 2W yuan TV call, in addition to the sound quality Harman Kardon's blessing, the performance of the scene also broke the limitations of conventional television, watching movies at home can be a very enjoyable process. Someone may ask, is this a million yuan worth of TV? You need to know that every little bit of experience improvement requires a lot of R&D manpower and material resources to achieve the best results, just like the difference between a 100W car and a 20W car, although the price of the TV is in the domestic TV. It is more expensive, but for foreign TVs of the same specification, it can be said to be conscience. If you want to enjoy the best audio and video effects in one step at home, then XESSX3 must be the best choice for around 10,000 yuan.
