Tianlei billing or the conscience of the industry? Do not blow black, Thunderbird I55 HDR TV full evaluation week (with PS4 test results)

In the past two years, there have been more and more Internet TV brands, such as millet, cool open, storms, and still-life, and last year, with the ultra-high cost-effectiveness of Zhang Xiaoma's micro-whale, it can be said that there are more and more choices for consumers. The unified features of these online TVs are higher face value, more network resources, and more feature-rich than traditional brands. However, the common problem of domestic TV is that the pursuit of LCD technology is slower, because playing PS4 , so I have always been more concerned about HDR technology, but in addition to SONY and LG, Samsung, domestically, are basically fighting the ball "support HDR10 video." When I first saw thunderbird Internet TV information on the website, my first reaction was: Can Thunder members not sell it? Switch to selling TV?

After purchase No screw backboard design: TCL launch Thunderbird Internet brand released four new TV brands Following the launch of TV brands such as Skyworth, Konka, Haier and other traditional TV brands, TCL held a conference in Beijing on the 29th of this month to launch its Internet brand — - Thunderbirds. At the same time, there are four new television products, covering three sizes of 32/49/55, of which 55 inches are also divided into flat and curved version. The I55 flat-panel LCD TV has now opened a new product reservation in Jingdong. The pre-sale price is RMB 3,999. It will be at 10:00 on April 5 26 Comments 55 Favorites 18 View Details

Open the page and found that the original is the TCL's network brand, read the introduction, one of the features that make me shine is that the brand television equipped with hardware native HDR technology, while supporting Dolby Vision, HDR10 and HLG three HDR standards (Dolby The relationship between Vision and HDR10 will be described below. It should be the first domestic company to support Dolby Vision. Rice no need to check, and Xiaomi 4A only supports HDR10 and HLG. But also MEMC motion compensation technology, the price of pre-sale 3999, the appointment successfully reduced by 300, the first 500 back to 500 yuan e-card single, so get the price of 3299 yuan. Since the price of TV components has risen this year and the price has generally risen, the current price of 3,299 yuan can be said to be very favorable. Therefore, Jingdong orders quickly, and the next day it is handy. In order to be responsible for the valued friends, we played. For almost a week, it was only today that he wrote boldly and impartially.

installation

The TV and the stand were two separate parcels and they looked at the factory date on March 29th.

Because he often hands-on, do not need to install the master, and directly demolition. The bracket is very thick compared to the previously purchased micro whale and cool open, and it adopts a satin-aluminum process to hollow out the design.

There is also a non-slip mat below the base to prevent it from touching the TV cabinet.

In addition to the pedestal, the box is also equipped with three back panel covers and trim strips. Some people may be weird. Why don't you have the back cover? In fact, it has other uses than decoration.

Fearing to smash the screen, she moved the TV to the bed at a stretch and gave it a base support.

Exterior

The successful completion of Thunderbird TV does not use the domestic popular "upper and lower convex" design, but more international design trapezoidal design, there is a slow contraction transition from the bottom to the top.

The left side of the back is the TV's power button, and the side has a USB2.0 interface, which is convenient for users to insert the U disk, which is praised.

On the back of the interface in addition to the three HDMI 2.0 interface, there are cable interface, USB 3.0 interface, 3.5mm / fiber combo interface, as well as the gradual elimination of the analog interface for the user to connect to the set-top box, basically used The interface has.

The right side of the back is the elbow power connector.

Is the effect after plugging in the power cord and HDMI video cable a bit messy?

At this time, the use of the back plate cover is reflected. In addition to covering the screw hole, another role is to store the wire.

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 will not be visible, just like on the picture.

Let me talk about the front, the perimeter of the LCD panel made a layer of aluminum panel borders, the top is black aluminum, the front is silver, have done a polishing effect.

However, with the brighter color of silver, if it is not spliced, it will look a bit like a paint drop.

At the bottom of the front of the TV is the brand's LOGO and breathing light, which can show the power of the TV.

This TV can also be wall-mounted, but there is still no time to get these two days, so for the time being put above the chest of drawers.

Picture

First tested the boot speed, boot without ads, boot without ads, boot without ads, important things say three times, from the press of the boot button to operate, about 24 seconds, basically satisfied.

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 LCD panel, in fact, the supply chain can basically be solved. For example, domestic TV has more challenges now than the backlight and circuit driver board. On the other hand, foreign manufacturers can theoretically use a little LCD to make a good picture. .

Bad spots, dark spots, bright spots

First test the bad spots, we can go to the application store to download some screen detection software, because it is a new brand, even before the receipt of the goods are afraid of bad things, after their own four-eye scanning inspection, I was very happy and did not win. In recent years, the quality of LCD products has been getting better and better, and the odds of winning are getting smaller and smaller.

Leakage

In terms of light leakage, TV manufacturers are now learning to be smart and invented a trick called “Physical Light Control Dafa”. A layer of approximately 1.5 cm of black border is placed between the border and the edge of the screen. This solves the problem of large-scale light leakage of liquid crystals. Now.

However, I also found a problem that the brightness of the panel will be uneven, and I found that the right side is slightly brighter than the left side.

color

The overall color is gorgeous, but the transition of the blue area is not natural, but slightly worse.

Smear

The afterimage is perfect, and the TV's circuit board is still good.

HDR

This is the main feature of this TV, so alone.

What is HDR?

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.

HDR advantages

Brightness - We can experience what is called "brightness" on HDR TVs. For example, the HDR version of "The Hacksaw Ridge" scene will brighten your eyes. Because HDR's backlighting system exceeds 1000 nits, superb brightness makes the dark contrast in the scene more visible.

Color-HDR TV's color theory is more color than ordinary TV display. Because the content of ordinary TV supports the Rec.709 color standard, the current 4K TV and content are 10-12 bits of Rec.2020 color space. Rec.2020 color space is 60 times the color of Rec.709, and the total number is over 1 billion. Of course, if you use HDR TV to play non-HDR content, the displayed color is still the color space of Rec.709, so you need to have HDR format movies or games to experience the HDR function.

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.

For the average consumer, if you see Dolby Vision and HDR10 certification, I recommend purchasing Dolby Vision, because Dolby Vision is also compatible with HDR10 format playback, but HDR10 does not play content specifically created for Dolby Vision. .

HDR standard

China Electronics Standardization Institute and China Electronic Chamber of Commerce jointly issued the "HDR Display Technology Certification Specification."

Input signal (supports 10bit, ITU-R BT.2020 color range signal input), high dynamic range (support SMPTE ST2084, Hybrid Log Gamma or other high dynamic range OETF curve), color gamut coverage (≥37.4%), peak brightness (Hardness ≥ 800 nits, OLED ≥ 540 nits), black brightness (LCD brightness ≤ 0.05 nits, OLED ≤ 0.0005 nits, dynamic range (LCD brightness ≥ 43%, OLED ≥ 60%) performed HDR technical requirements.

--------Dividing line------

The biggest feature of this TV is that it supports Dolby Vision HDR authentication and comes with an HDR authentication and detection chip. However, since Thunderbird TV's maximum brightness is 450 nits, it also belongs to the low-end version of HDR, but the brightness is still far beyond the same price point. Some Internet TV brands, then how is the actual performance?

I used the most popular PS4 game console for testing because it supports HDR mode and of course, PS4, I bought this Thunderbird TV. The game tested used "Uncharted 4".

First of all, it is necessary to open HDR in the settings of the PS4 and in the game. This is also a good helper to detect the TV HDR function.

The daytime scene was selected first. In contrast to Figure 1, the HDR image was more natural than the SDR, such as distant mountains and clouds in the sky. Figure 2 shows the performance of HDR in light effects. In fact, the part of the grass is the shadow of the game. The flower is the place where the sun shines. The HDR's image can clearly see that the brightness of the flower's location is higher, and the SDR's feel that there is no sense of light in the grass.

Two night scenes were chosen to test the light effects. The main difference between SDR and HDR is that the HDR lights look more natural, and the street lights are layered and warmer. Figure 2 The HDR version of the enemy searchlight shows the light scattering more realistically.

Of course, Thunderbird's HDR is not a standard version, because the brightness does not reach 1000nits, so HDR can be said to be able to distinguish the difference with the SDR, play video and audio effects further.

The deepest thing I personally feel about it is when the enemy swipes the Thunderbird's screen with a flashlight. The brightness will flash. My eyes are a little unbearable and there is an immersive feeling. If you are experiencing the high-end HDR TV with 1000nits brightness, the effect of the game It will be better and more realistic.

Panel delay

Panel delay I use NBA 2K test, because playing for many years, is very sensitive to the player's shot time in the game, 2K17 also strengthens the player's control of the player's shot time. I used to use game monitors to play 2K before, because the delay of the monitor is very low, only about 13 milliseconds, when the shot will feel very smooth; Sony is very aggressive in this regard, 950B is only 17 milliseconds, but the price Touched, break ten thousand. The Thunderbird also has a sense of delay. Unlike the previously used Cool Open, it clearly felt an input delay of at least 0.3 seconds. After playing a few games, it took about 40 milliseconds after equipment testing. This is basically acceptable.

other aspects

The TV's image has a lot of adjustable content, such as "paint effect", "backlight brightness", and "ambient light sensing".

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 also supports the "anti-blue eye protection" function, more suitable for children.

system

As shown in the picture, the Thunderbird TV's main UI is displayed. The Banner position on the front page shows some of the most popular television dramas recently. Then, like LeTV, there will be a Thunderbird 24-hour loop of various internet TV stations, such as TV dramas, movies, documentaries, etc.

Swiping to the right means subdivided categories, such as movies, variety shows, NBA, animation, 4K movies, etc. Since Thunderbird is deeply involved with Tencent, most of the TV's own resources come from Tencent's video.

Of course, the user can also subscribe to and sort the classification of the TV and remove the columns that they do not need. This is still good, but the four commonly used ones are fixed.

In terms of resources, Thunderbird sent Tencent VIP members for one year. The update speed of the movie is basically the same with iQIYI and Youku. After the general theater is offline, it can be viewed through TV.

In addition, there are "Ding Theatre" and "NBA Tournament" super affiliate programs on TV. The price is above and everyone sees it.

Personally feel that NBA games are still worthwhile, because Tencent's sports membership is also divided into the normal version and the advanced version, only the premium version can see all the NBA games, one month cost 88 yuan ...

Every day's game HD playback and ten balls can be found in the NBA column.

Each NBA team also has a corresponding page that provides more detailed information, such as the team's data, schedule, and short video news for various players.

I also support skip header and resolution selection during playback. At the moment, I'm also considering whether or not to try it for a month because I'm playing the playoffs right away.

Voice function

The TV remote controller has a dedicated voice button, which is very useful. By pressing the voice button, the voice function is turned on. After the release is complete, the voice search is completed. The movie name, the actor name, and the type to be viewed can be identified. Waiting, the elderly and children can use it without difficulty.

Other fragments

Install App

Users can use the U disk and other means to install some of their favorite APP, for example, I installed music video and television cats, to supplement resources. However, because of the permission design, TV does not support the "sofa manager" APP market and requires users to download the related software APK through the computer. This design is safer for Xiao Bai. It is more troublesome for enthusiasts.

However, it is troubling that the pre-installed APP can't be deleted, taking up space. If I find a way to delete later, I will tell you the first time.

Video playback

The basic configuration of the TV is Mstar838A, 2G memory plus 16G 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, the TV also supports wireless protocols such as Airplay and DLNA, which are not summarized here.

to sum up Thunderbird (FFALCON) I55-UI 55 inch 4K HDR10 artificial intelligence metal frame 64-bit 34-core high-performance processor LCD TV (standard rack) (silver) 3999 yuan Thunderbird (FFALCON) is the TCL launched in 2017 Internet Sub-brand. The I55 TV uses a 4K resolution panel equipped with hardware native HDR technology to enhance contrast and brightness for sharper details. Supports HDR standards of Dolby Vision, HDR10 and HLG. The maximum peak brightness in HDR mode can reach 450nits. QUHD Tur Jingdong direct link View encyclopedia

Wrote so many, when the mouse I used to sum up the advantages and disadvantages of this TV:

advantage:

Excellent design, solid materials

No ads on startup, system is simple and practical

HDR 10 and DOLBY HDR native support

Motion compensation & voice function is the highlight

Disadvantages:

TV color transition is incoherent

Uneven backlight brightness

Cannot delete own APP

So is it worth buying a 4000 yuan TV? My answer is value. First of all, it should be the first low-cost TV to support Dolby Vision HDR. The effect of HDR is also relatively satisfactory at this price point. After all, a penny and a receipt, if your budget is limited If you want to buy a TV for the PS4's HDR function, Thunderbird is a good choice. In addition, there is no advertisement, voice function, and motion compensation, which are very practical for the average consumer. Then the disadvantage is that the panel tuning is not as good as the big manufacturers and international brands. The color is generally the same, the other is the initial quality control is still a bit problem, mainly reflected in the uneven backlight, I believe that later manufacturers will also be improved. Faced with the general price increase of online TV, Thunderbird's initial price is still good, but if you want to experience a better audio and video enjoyment, Sony, LG is also a good choice.
