Foreword
I am an idolist and academic type reeling leftsky left two
Thanks Aunt, this is the first big thing I got from this year (Tucao: The editor of the test interface doesn't feel comfortable)
I really burst into tears.
At the time of writing this review, I hadn’t arrived at the date of submission. I don’t know if I can do it all at once and deliver the manuscript on time. So if you see any delay in this report, please do not blame the netizens and officials. ....
brand introduction
LG Electronics
Korea LG Group was established in Seoul, South Korea, in 1947. It is located at No. 20 Kojima-dong, Yeongdeungpo-gu, Seoul. It is an international enterprise group that leads the world's industrial development. LG Group currently has more than 300 overseas offices in 171 countries and regions. The business area covers chemical energy, electronics, communications and services. LG is the first letter of Lucky Goldstars, the translation of Lucky Star, and it also covers various brand images in the corporate sector. In China, the meaning of LG is defined as life "s good, life is beautiful! Do you feel like a beautiful slogan?
LG is a leading manufacturer of LCD panels for global shipments, and is a technology leader in IPS panels. Many mobile phone manufacturers including Apple have adopted LG-produced screens. IPS hard screen technology LCD panels are not only durable and easy to clean. It has certain advantages in terms of performance, and it also leads the VA soft screen in terms of function parameters and performance indicators. The response time has always been a shortcoming of LCD TVs, but with the continuous advancement of LCD technology, the problem of smearing of LCD TVs has been well solved on IPS panels. The advantage of short response time enables the IPS panel to display clearer images in dynamic pictures. In addition, the IPS panel also has performance advantages such as accurate color reproduction and outstanding black expression performance compared to the VA soft screen.
Arrival unpacking installation
Aunt Zhang used Debon logistics to deliver goods, and Debon logistics only went to the downstairs. Fortunately, I lived in an elevator.
The wooden box outside the TV box is very firm and the package is like a
But... The craftsmanship of this wooden bar is a bit rough, and I broke my pants.
Shantou battle, unpacking is so cool
LG has an energy efficiency rating of 2 and an implementation standard of 2013, with an energy efficiency index of 2.0. According to the 2013 edition of the “Tablet TV Efficiency Limits and Energy Efficiency Ratings†requirement, the energy efficiency index for Levels 2-3 should not be lower than 2.7, 2.0, and 1.3. LG 2.0 seems to be a bit of a sideline. As a new product, individuals feel that it is best to raise the energy efficiency index to one level.
Before the preparation of their own installation, they bought a NB rack in Jingdong, unpacking saw the installation of the box on the installation services, TV racks are also clearly the price, so they would like to steal a lazy, to LG after-sales installation A phone call, said to install, LG's customer service asked me where to buy the invoice, I will directly sentence: send, no invoice, to security does not? After waiting for a minute for instructions, customer service expressed that as long as it is LG's brand-new genuine product, it can provide free on-site installation service with or without an invoice, and makes an appointment at about 2:30 in the afternoon, and then waits and waits for the right, etc. To a phone call, it was an installation master who said that there were too many homes today, and that it was too busy to move to tomorrow. At that time, I said there was no time tomorrow. I must install it today. I am at home all day. I am not in a hurry. You can be slow. Slowly loaded the other family came to me again, but today must be installed, the master reluctantly agreed, wait until 9 o'clock at night, the master finally came, in fact, I thought that the master will not come .....
The installation process was very sad, because the living room used a projector, did not stay in the TV, the main bedroom I put three computers, do not watch TV, so it was installed to the guest bedroom, just to solve my mother always complained Can not lie on the bed to watch TV problems, but this guest bedroom TV wall is a hollow brick ah ..... The location of the racks I bought was quite picky. Therefore, the master was busy with this TV for almost an hour, played nine holes, and finally found only three holes that were not hollow, and they were barely loaded.
I only renovated the house, there are so many big holes on the wall.
The score for the installation master: 4 points (out of 5) Points deducted Reason: There is no official time for me to agree to... This should not blame the master, people are really busy, but the official after-sales did not follow the installation The actual situation of the work progress of the master makes a reasonable adjustment, which will affect the user experience.
Installed, did not photograph the master when installing I'm afraid that people think that I'm weird. In fact, the out-of-box process is the same kind of feeling that you are tearing down express parcels.
Then, next, we start a discussion about “thinâ€, “bigâ€, “fine†and “acousticâ€.
test
Thin
From the earliest CRT TVs, to LCD TVs, and now to LED-backlit TVs, the development of TVs is becoming thinner and thinner, which can save more limited space, thinness, lighter weight, and ease of handling. , thin, there is a more pleasant feeling (I'm not talking about Okamoto 001 )
LG49UF6600 uses ultra-thin and ultra-narrow frame design, in the backlight mode using led side backlight to reduce the thickness of the whole machine. Through actual measurement, in the thickest position at the bottom of the motherboard and the interface concentration, the thickness is less than 5cm, the thinnest point, only 1cm, the overall average thickness of 3cm, such a thickness is so well controlled in such a large TV.
Since the TV has a built-in motherboard and a power transformer module, it is difficult to achieve a uniform thickness as a whole. In order to reflect the overall aesthetics, the overall thickness of the LG49UF6600 is evenly distributed over a curved line, and the back panel is fully white. The design echoes the golden front panel border to create a high-end atmosphere.
The design of the ultra-narrow frame brings only a border thickness of 9mm, and the overall visual sense is greatly highlighted.
Installation method
The installation method, LG49UF6600 provides a mount and mount two ways
I am using a hanging method, equipped with a standard VESA wall mount hole, four hanging hole design, I do not recommend buying this type of hanger I use when purchasing the rack, the specific reasons behind Say.
The LG also comes with a cradle for the box, which uses a two-legged pedestal to better balance the weight of the TV (these two images are from the Internet).
2. Large
The appearance of the development of home TV in addition to the thin theme, is constantly large, from the earliest 29-inch CRT TV, and then into the LCD after the 32-inch, 42-inch, up to the 49-inch LG49UF6600, more and more The panel size is the development trend.
49 inches, 1 inch = 2.54cm, 49 inches is the diagonal of 124.46cm, the screen ratio is 16:9, conversion width is 108.48cm and 61.02cm wide, the area of ​​the entire LCD panel has reached 0.662 square meters, for the general In terms of the housing area of ​​the reeds family, it is definitely enough (Regardless of local tyrants)
LG49UF6600's "big" when not only reflected in the area of ​​its LCD panel, but also reflected in its resolution, 3840x2160 Ultra HD resolution, which is commonly known as 4K, 4K film source is equivalent to what? The equivalent of more than 8 million pixels per frame of the picture, an 8 million pixel photo is generally around 2-3M, then a 4k video? I was scared to think about it. I hurried to do a 100M broadband.
Speaking of 4K, we need to talk about the very popular 4K disputes
4K refers to the physical resolution of the display is, the traditional pixel consists of R (red), G (green) and B (blue), referred to as RGB, but the panel manufacturer has developed a 4K specification in 2014 The panel, called RGBW or GreenUHD, adds a W (white) seed pixel. With the increase of sub-pixels, the RGBW4K panel can also achieve higher resolution. Samsung Electronics refers to its RGBW panel as GreenUHD and LGDisplay as G+UHD. If the traditional RGB technology, UHD panel light transmittance is only 60% of FHD, which requires the use of backlight modules. However, RGBW has no such problem because it can provide better light transmittance. In fact, 4K everyone really look like, in theory, the actual pixel RGBW is 6.2 million, RGB is 8.2 million pixels, but the increase in the transmittance of RGBW, can reduce the backlight module, more power, as to draw The difference in quality is not as great as the naked eye.
interface
LG49UF6600 provides multiple sets of external interfaces, as shown in the figure, provides two sets of USB interface, you can directly plug U disk and mobile hard disk, one USB interface is usb3.0 specification, high-speed can support smooth playback of 4K video, two Each HDMI interface is 1.4 specification interface, supports 4K resolution input, although the built-in wireless network card, single is still provided in the back of the wired network port, at the same time, the audio output is not only 3.5mm headphone output hole, as well as fiber optic audio Output holes, output more pure digital audio signals, AV / component input interface each set, while also retaining the rarely used traditional cable TV interface, the interface is more comprehensive.
Due to the mistake of choosing the rack, my AV and component input ports are basically blocked. Fortunately, these few ports are also basically useless. The slightest deficiency is that the USB ports are too close to each other. U disk to take the unusual road, double disk will be some difficulties.
3. Fine
Finally talked about the topic of "fine". When it comes to precision, we must mention one feature of this TV.
Yes, is LG's own smart TV platform webos
As we all know, with the advancement of intelligentization, TVs have begun to follow the path of intelligence. Whether Skyworth, Hisense or Xiaomi have their own smart systems (all Android-based), LG is the exception, using web0s.
About webos
Webos does not belong to the Android system. The earliest full name is Palm webOS. Palm webOS is an embedded operating system, with the Linux kernel as the main body and some proprietary software developed by Palm. It is primarily developed for Palm smartphones. The platform was announced to the public on January 8, 2009 and was released on June 6, 2009. The platform is the de facto PalmOS successor, and webOS focuses on the integration of online social networking and Web 2.0. The first smart phone equipped with a webOS system was plam pre, which was released on June 6, 2009. As Palm was acquired by HP, webOS was taken over by HP. On the early morning of August 19, 2011, at the third quarter earnings conference of Hewlett-Packard, Hewlett-Packard announced that it officially abandoned all operations related to the TouchPad tablet and webOS phones.
Subsequently, LG acquired the entire assets of WebOS from HP HP, including source code, employees and related patents. Since then LG has been relatively low-key. However, at the International Consumer Electronics Show in Las Vegas, webOS relaunched. In LG's webOS smart TV, a webOS classic card-like interface was adopted, and some commonly used mobile clients such as Facebook and Twitter were simultaneously launched. , YouTube, and mobile browsers. In addition, users can quickly switch between multiple applications. According to media commentary, in the eras of Palm and HP, webOS completely failed in the consumer electronics market. From the perspective of LG's exhibiting pictures, LG is ready to make webOS the protagonist of the exhibition and let it embark on the journey again.
Webos settings
The first thing to do after booting is to select regional language and network connection, enter the password, and the wireless signal shows a full grid behind a wall. At the same time, the wifi module uses dual-band support, and the 5G-band wireless signal can also be connected. .
After setting, it needs a certain buffer time. This buffer interface is also designed to be adorable.
Set up to watch TV! Let's take a look at the webos2.0 system interface that this TV is proud of.
Press the home button of the remote control, the webOS system's iconic card menu pops up, and the application you want to enter is swiped right and left. The quick launch bar that pops directly in the playing screen not only loads faster than the traditional homepage, but also allows you to switch to the columns you want to watch with one click. It is very convenient. And the system will automatically memorize your previously played content, and automatically continue broadcasting after the user switches. The main online content is provided by Wahite TV, which is selected by the left and right arrow keys. Huaxuan also offers multiple types of film sources for selection.
But ..... This movie is not quite right for a lot of charges..... Although it provides a 10-day VIP experience for newly registered users, we want a permanent VIP experience.
What is the application of smart TV? ? ? Of course, a built-in application store provides a variety of applications and games, but the number <100 ah, lg acquisition of webos has also been for some time, but now it seems that the development of the application has not fully tried, We hope that more applications will be developed. However, one of the features of WebOS is Web-based. Developers can use Html 5 and other languages ​​to easily develop.
The body provides two USB ports, usb2.0 interface we can use to connect wireless mouse and keyboard, usb3.0 interface we can use to connect external storage, in smart sharing, can intelligently identify external storage photos, videos and music, usb video format support DivX HD, RMVB, audio formats supported AC3 (Dolby Digital), EAC3, HE-AAC, AAC, MP2, MP3, PCM, DTS, RA, WMA, JPEG photo format support
At the same time, it also supports multi-screen interactive gameplay
Music does not support wav lossless format, in fact, this is not important, according to the hardware configuration, we only need to install a music player can solve this problem
Compared to the current 4K source, Huada also provides some 4K sources, including some free films. Let’s take a look at the proofs.
It can be seen that the 4K film source has a strong visual shock when playing on this TV, the picture is clear and bright, there is no graininess, we can only lament that there are too few 4K sources, and there are fewer free ones (only the scenery is Free
I took a magnified screenshot from close range to feel the 4K dot matrix!
At the same time, because of the use of an IPS hard screen, the viewing angle is also greatly improved, and no apparent color difference is observed from the left and right sides. However, you can see a significant light leak at the edge of the screen.
Two more play samples
The picture is really good.
Screen test
Screen Test I used Starscream to test. After connecting to the computer, I found that the computer screen did not automatically adapt to the screen completely. After the point-to-point display was selected in the menu, the screen was perfect.
The first test is the color gamut
The gamut is a complete subset of the colors. The most common application of color subsets is to accurately represent a given situation. For example, a given color space or the color rendering range of an output device.
We tested this screen with professional testing software. 99% of the sRGB color gamut, 71% of the NTSC color gamut, and 76% of the AdobeRGB color gamut. From the color gamut point of view, the screen performed more or less often. The screen color gamut of the phone.
In brightness uniformity, the left and right sides have a maximum difference of 14% from the center, mainly due to the use of the side backlight, resulting in the center brightness being slightly lower than the periphery.
At the same time, the color accuracy is 1.31, the maximum is 5.99, and the average is 3.27. This value is more general from a digital point of view.
Let's take a look at the test chart
Grayscale test
256 gray scale test, you can see the top left corner of a few maps are basically indistinguishable
Grayscale test, the transition is fairly smooth
Geometry test, slightly deformed circle
Color transition test
Solid color test: red
Solid color test: green
In the settings interface, the aircraft also provides a number of settings, not only multi-screen mode and sound mode, but also security and access restrictions set, at the same time, the machine supports wifi direct connection, you can easily share the files on the phone.
product details
LG's remote controller is not as simple as a TV box remote controller. Instead, it integrates multiple buttons. We can easily enter the interface we want in one click. We can see that there are recording functions on the remote control. The recorded video can be recorded. It can be used after it is plugged into the USB, but it cannot be recorded by the HDMI input. The bottom of the remote control is designed with shortcut keys for playing video and 4 custom keys. All functions can be basically called up by the remote controller, which is quite convenient.
The radiating hole on the back of the fuselage makes a groove, simplifying the opening on the back of the body.
The speaker is set at the bottom of the TV and has good concealment, one on each side, and a total output power of 10W.
In the standby state, the indicator light at the bottom of the logo will remain in a steady state. At the same time, there is a physical button at the bottom of the indicator light. The overall LG TV is very simple, which is the only physical button on the body. The function of this physical button is not just the function of the switch. In fact, this is a five-dimensional navigation bar. Long click can be used as a key, and the up, down, left and right are corresponding to the channel selection and volume control, and the operation is also very convenient.
Although the spacing of the side of the interface is somewhat small, but the vertical space is generous, do not have to worry about the U disk is too long.
The fit of front and rear panels is also quite neat.
4. Sound
TV as an entertainment product, we feel the effect of audio and video synchronization, the traditional television manufacturers pay attention to this piece of sound is often not enough, let's take a look at how the LG49UF6600 investment in the sound of this piece?
As an ultra-thin TV, it is impossible to add high-power and large-size loudspeakers, but LG has no ambiguity about sounds. It not only has a variety of sound effect modes built-in, but also provides sound optimizer and sound-image synchronization adjustment.
If the built-in speaker does not meet your sound quality requirements, the LG49UF6600 also provides a high-quality sound output mode - optical fiber output, we can use the optical output to external high-quality speakers to bring the acoustic shock.
In fact, I used U disk to play music, feel the sound quality effect, no less than 500 yuan price speaker products, bass slightly sinking not in place, although the treble extension is not enough, but from beginning to end, did not break the sound. Audio support MP3, FLAC, WAV and other formats, playback can be operated through the remote control's playback shortcuts. Setting an automatic shutdown before going to bed and listening to music is also a good feeling.
to sum up
Let us first review the parameters of the LG49UF6600
