I. About LG
A variety of home appliances industry will have the existence of LG, but my biggest impression on LG is his home IPS screen panel, whether it is mobile phones, monitors, television can see LGDisplay IPS panel figure, as long as the IPS panel The reaction was produced by LG, although Hitachi and Matsushita actually produced IPS panels. The IPS screen was first invented by Hitachi, and it was LGD that made the IPS screen go beyond the VA screen, and the most impressive one was the IPS screen produced by LG on IPHONE4. It has been through the trend of Apple since then. LG is basically synonymous with IPS, and IPS is basically synonymous with wide-view hard screens. I used a computer a few years ago to compress the graphics card for IPS. Sacrifice the hardware performance. Choose LG's IPS236V monitor. Although other brands also have IPS screens, I always feel that buying other brands of LG screens is not as direct as buying my own IPS. The panel's LG, in general, will not be too bad for its own brand of panel.
Although LG's IPS panel has a very high market share, the share of LG's own monitors and LCD TVs is not so high. One of the main reasons is that brands such as Samsung and LG have their own panel production capabilities. The cost of using their own panels is relatively high, and the price is expensive. Many other domestic brands use Taiwan's Chi Mei, AUO, and domestic panels with low cost and low prices. I always wanted to give my parents the old-fashioned CRT TVs that were replaced with liquid crystals, because the LG monitors that I used all the time feel very good, so I have been watching LG TVs.
II. Preface
When the company was struggling to do the work of cattle and horses, she received the stimulant from Aunt Zhang and secretly laughed all day long. Because I have been watching TV, I have carefully watched all the TV public test reports here, so when I received a successful SMS message, I thought that my mom would definitely use Debon logistics and would play a wooden frame. After the shipment, I saw that the logistics information contained “Vehicles (not including delivery upstairs)â€. Then the question arises. How do I get a tens of kilograms of TVs upstairs? . . . . Hurry to apply online to change the delivery method to delivery upstairs, thinking of the increase in the cost of delivery delivery on the line, the results did not take long to receive Debon phone was told to go upstairs free of charge but to 5 change fee, and has I contacted the shipper and let the other party pay out. I suddenly felt very embarrassed. Aunt spent more than 200 logistics fees, the last 5 dollars also let the mother stunned, and I knew it would not change the money directly to let the deliveryman moved to me. . . . .
The gross weight of the TV itself is 17 kilograms, and the wooden frame is almost 10 kilograms. In fact, if the weight is still within my tolerance range, it is still too big to start.
With the wooden frame basically do not have to worry about the logistics damage, that is, some bumps on the road to break into the packaging carton, a bit worried about hurting the screen.
The problem has come again. The wooden frame has never been dismantled. The first time it was unpacked, I realized that I would like to disassemble a parcel and a knife would be able to handle the idea. I was wrong, and I had to buy a whole set of unpacking tools online. : Hammer, pliers, screwdriver. . . . Nails are bought by the way.
The nails were all shot with a nail gun. All of them went into the wood, and they bought a screwdriver and gave them a hammer.
After a long time, he finally removed the side and finally pulled out the box.
Third, out of the box
The label on the side of the box is affixed with a production label. The model number of the TV is exactly 49UF6600-CD. LK Electronic (Shenyang) Co., Ltd. is a joint venture between LG Electronics Co., Ltd. and China Changbai Computer Group Corporation. The Chinese name of LG is Lexi. Venus, Le Jin is the abbreviation of Lexi Venus, and basically did not even hear of LG's Chinese name. HDMI is very conspicuous, but it does not identify 4K features.
The other side of the box identifies the size of the TV and the package. Produced by the new spectrum company, this is a company specialized in TV production for LG.
The TV is fixed with a foam board and the power cord is placed in the groove on the top side
On the other side are two brackets. The big two letters should be used to distinguish the installation position, but what's wrong is that I didn't see the manual saying that the two brackets should be installed on which side of the bracket. No corresponding letter was found in the position. . . . .
Brackets, like TV, are tightly packed in plastic paper.
The bracket is not a symmetrical structure, one side long and one short
There are two very small non-slip rubber mats at the bottom of the stand, which are not very demanding for televisions with such a high center of gravity, because if they are not flat, they will fall down without sliding. The bottom lattice can increase the strength of the stent
There are also AB letters on the back of the stand, and there are many strings that do not know what it means.
Fourth, accessories
All the things in the box are combined and you can see the parts are poor.
As a piece of more than 5,000 pieces, the accessories presented by this TV set are not really much. All the accessories are in this plastic bag.
A cable tie used to organize all kinds of TV wires
Antenna isolator
According to the instructions written on the instructions for the set-top box to prevent fire, Duan Niang's explanation is this: to eliminate the potential for self-ignition, fire and other dangers caused by the potential difference between the power grid ground and the cable network cable, TV Image, sound and AC interference, and equipment with a certain lightning protection function (with discharge tube)
The length of the power cord is about 1.4m. I think the 1.4m is a bit short for a TV with a length of more than 1m . The plug on one end of the TV is a built-in contact that prevents electric shock when the plug is charged off.
Presented two 7-cell batteries for the remote control. I installed it on my own. It was originally separated and I forgot to take it.
The buttons on the remote control are still quite numerous. There are blind spots on the number keys and the volume program keys. You can find the desired keys without looking at the keyboard, but there are no blind spots on the direction keys. When there is no light, I can't find where the arrow keys are . When you look closely, you can also see that there are blind spots next to the power button and the volume program button. It seems like it is Braille, or it is more careful.
The bottom row of buttons on the remote control is like a dice's icon for some special selection functions, but I have not used it. The bottom of the string should be the remote control model
The side of the remote control is streamlined and feels good. The light weight of the head makes the center of gravity all in the palm of your hand.
The infrared light at the top of the remote control indicates that the remote control uses infrared instead of Bluetooth , or it is inevitable to use the receiver on the TV.
The surface of the remote control is not smooth but has longitudinal grooves for slip resistance
However, I still prefer the LG's dynamic remote control, which has a scroll wheel that can be used as a mouse. Unfortunately, although the 49UF6600 is known as the flagship TV, the remote control does not come standard with this high-end remote control.
6 various manuals. This TV's accessories are indeed a little less likely, in addition to the power cord, there is no other wire, HDMI, cable signal line these wires must be prepared, and there is no wall bracket, need to buy another
V. Details
As soon as the TV was found out, it was a problem. A screw was loosened directly. Fortunately, I heard the sound. If I don't know where to go, LG's quality control should be careful.
The thickness of 18mm is relatively thin in the current TV. From this, it can be clearly seen that the TV frame is divided into two parts. The front part is a golden metal frame and the latter part is a white plastic frame.
Just below the screen is LG's LOGO. The white part underneath the LOGO is the receiver of the infrared signal. There is also a red indicator light. When it is in standby, it will light up. When it is turned on, it will go out and prevent the viewing. influences
The only physical button on the TV is behind the receiver. This is a paddle-type button that can be pressed down or moved in any direction to enable all selections of the TV system.
I still like the kind of mechanical switch, the switch is simple and clear, the biggest problem of this electronic type is not cut off the TV power supply, the TV is always in the standby power state, and the shutdown is also troublesome, it is necessary to press several times before
The trumpet of the TV is also hidden at the bottom, one on each side
The ULTRA HD Full HD logo in the lower right corner indicates that this is a 4K TV. The rear frame at the bottom is one turn larger than the front frame. It should be to hide the middle receiver and make the front metal frame less monotonous. The metal frame is also very narrow, except for the width of the other three sides just below the thickness of the IPHONE5S.
The back of the TV is pure white, the overall arc, the bottom widens, it looks like the electronic components are at the bottom
But when you look closer, you will find shallow copper coins on the top
LG is very clever to hide the heat sink hole in the backplane, which will not affect the appearance of the cooling hole, but also can avoid the dust directly fall into the cooling hole. However, I do not know if it is because the heat vent is too high for the sake of reason. After the television has been used for a period of time, the bottom left corner of the front metal frame cannot be touched! !
With 2 HDMI and 2 USB ports, HDMI is 1.4 from the data point of view , both support 4K, 60HZ video playback, including the second HDMI support ARC function , Audio Return Channel, sound return function, you can Audio amplifiers that also support the ARC function are connected via this HDMI interface so that the sound of the TV speakers can be played on the amplifier. One of the two USB ports is 3.0 to 2.0 . High and low collocation can basically meet the use requirements, and the cost will not be too high.
Interface is very complete, the upper left corner of the RS-232C do not know what to use, it seems to be the fiber interface, then there are network ports, headphone jack, digital audio output, AV input and antenna interface
Look here to see more carefully
Three-phase power interface
Bracket mounting slot, two screws fixed, fixed position slot at the top, two positioning crosses below
The mounting screws of the bracket are provided with gaskets, which can apply a greater fastening force without damaging the bracket.
Bracket and TV mounting fit
Originally intended to open the back cover to see the inside of the hardware configuration, but I put all the screws are removed after a long while did not open the back cover
Can only remove the switch to find the original back cover and the front panel there is such a plastic buckle buckled, can only give up
Sixth, hardware evaluation
First of all, look at the hardware configuration of the 49UF6600, 4K is its biggest feature, and the interface configuration is very complete
49UF6600 parameters do not look very good, then come back to the actual evaluation
1, color
49UF6600 screen color reproduction is still good, the color is also beautiful . The above are all shot with an Apple phone. The camera's performance seems to be uneven, and the actual effect is very good.
The screen brightness official data is 200cd/cm2, the actual test brightness is relatively high, grayscale performance is also very good, but the phone shooting a little error, the actual display effect is very good
2, visual angle
The viewing angle of the screen is also very large, almost up to 180 degrees, and the change in color is also small at large viewing angles.
3, point to point display
When the HDMI is connected to a computer, the screen's default raw display effect makes the screen edge outside the screen and cannot be displayed
Only in point-to-point mode can the computer screen be perfectly displayed on the TV screen
4, delay
The delay is mainly a parameter that is considered when the TV is used as a display. In this delay test, the 49UF6600 and the LG IPS236V monitor are compared. The same computer is used as the signal source, and the delay time can be compared with a program that can be accurate to milliseconds. , shooting with high-speed photography, click on the pause at any time to see the difference in the delay of the two devices
From here it can be seen that the delay gap is basically maintained at about 76 milliseconds, with a small value, but there will be a gap in the game, especially for games that require precise operation.
Let's take a look at the actual comparison of the game and use GTA5 to test the action of throwing the gun. In this kind of game, the delay of the screen has a greater impact on the precision of shooting. The video is shot at a speed of 120 frames per second and can be obviously felt. When the gun is stopped, the TV is slower than the monitor.
From the screenshots, you can also see that the delay gap has basically led to the television's front sight being half a screen slower than the monitor. The stand-alone game is okay. If it is an online shooting game, it is basically the ending of the headshot game. However, this delay is not caused by the screen. Most of them are caused by TV chips or cables. This HDMI cable is not very good. The reason for this delay is also the HDMI cable.
5, smear
With PixPerAn smear test, the display effect is still not optimistic, high-speed smear is still more serious. The official sports image trailing time is not greater than 32ms, this is a big number, in fact, such brands like LG and Samsung have the technology to control the trailing time to 5ms or less, indicating that 49UF6600 is not the best LG Technology.
Because the length of the exposure time will affect the displayed effect, the effect of shooting with a mobile phone will be amplified, and the actual use of the smear is still relatively obvious, high-speed things are basically difficult to identify the details of the above
6, light leakage
The light leakage problem of the 49UF6600 is rather serious. Although the LCD screens are inevitably leaking light, the leak of this TV is still beyond my expectations . The white dot in the middle of the photo is a mouse. The TV does not know whether it is for power saving or cheating on the light leakage problem. Whether it is a software or a black picture to test light leakage, if the mouse does not move or slides out of the screen for 2 seconds, The entire screen will be completely extinguished. At this time, no light source will leak out. Therefore, in order to shoot accurately, you must shoot with the mouse in the middle of the screen.
If it is a relatively bright scene that is not a problem, but if you see a dark scene in the movie or the upper and lower borders as shown in the figure above, the light leakage is still very obvious, the most serious light leakage in the lower right corner, the viewing effect There is a relatively large impact. I don't know if this leak phenomenon is a special case of this TV, or that the entire series has this problem, because in my impression LG's leak control has always been better.
7, sound
The lower limit of the audio test with the AUDIO 100 is about 125Hz. In general, the HIFI audio must be at least 80Hz. Regardless of the audio of this TV, there is only 5W of power, and there is no requirement for low frequencies.
The high frequency is relatively normal at 12.5KHz, which is also the upper limit of the general independent speaker
The frequency of playing sine sweep signals is relatively continuous and smooth, with no abrupt changes, and the left and right sounds are also balanced. On the whole, don’t hold any hope for the stereo on the TV, hope to have good sound effects or choose independent speakers.
Seven, WebOS
LG 49UF6600 is loaded with LG's own WEBOS operating system, but WEBOS is an untimely operating system. Palm was released on June 6, 2009, and was equipped with a Palm Pre mobile phone. , And 3 days later IPHONE3GS also released, the result is obvious, 3GS has attracted the attention of the whole world
Later WEBOS was transferred to Hewlett-Packard. Hewlett-Packard put it on his mobile phone and tablet, and even planned to pre-install WEBOS on his PC. He could give up in half a year and finally he took it to LG.
WEBOS was born to compete with IOS and Android, and even there was a downhill Saipan competition. There was a later WINDOWS system. After LG acquired WEBOS, it was not installed on LG phones as expected, but it was installed on LG. On TV, WEBOS is a bit like Nokia's Meego system, but it's hard to turn around. WEBOS still has a lot of fans. WEBOS has used a flat and fresh system interface earlier than IOS7 and Android. This is also a group of fans. Now it's really a feeling to use a WEBOS phone.
1, set
The first time the opportunity to automatically set the guide, the remote control displayed on the screen is not the same as me, in fact, read the manual to know that this is a dynamic remote control LG, 49UF6600 configuration is just an ordinary remote control
First of all, common language and regional settings
The TV is equipped with wireless WIFI function, which is very important and convenient. It can make the TV less of a cable, so that the back of the TV has been a mess of a clean line of points
The last is to select the TV signal source
After the settings are completed, you enter the main operating system page. The first thing you see is the most important feature of WEBOS: The card type is the first to see the number of TV.
There is a menu button on the remote control. After pressing, a vertical setting button will appear on the right side of the TV screen. From top to bottom, the screen, sound, picture ratio, sleep settings, parental lock, advanced settings
In the advanced settings, you can make in-depth settings for each indicator of the TV.
While on the physical buttons on the TV when the top of the operation is the shutdown option, the left signal source selection, right is set, so also see the physical key to shut down if you want to press a few times.
From the settings to see the software is 3.0 version does not know what to refer to. However, WEBOS can be upgraded automatically. It doesn't need us to flash anything, it's still quite good.
And WEBOS is 2.0 version, also can not see in the end what CPU is used in the end, and the memory is less poor, a total of only 0.79G, the remaining less than 60M
WEBOS has a very fast start-up time. It takes less than 6 seconds to enter the system every time. This is a big advantage compared to Android.
2, film source
WEBOS pre-installed the number of Chinese clients to provide Internet TV programs, which also shows that LG has not built its own resource library, can only rely on third-party resources , in the past few days, millet and LeTV tear a battle in a focus The problem is resource problems. This is also a short board for LG.
The number of APPs needs to be updated. The update is simple. Click to automatically update the installation.
After updating, the preview screen can be displayed on the current page
All pre-installed are the number of Chinese clients, CTS movies, China TV drama, China Sports, China Vision HD, and Chinese entertainment are equipped
But the biggest problem with China’s number is that movies are all about money.
In addition to movies, TV dramas, sports, and documentaries are free.
The clarity of the drama is OK, it should look at least 720P
There are only a few sources, and most of them are old ones. Although some of them are still being updated, they are basically domestic ones. There are also 30 overseas seasons, and there are probably only a few.
There are still some 4K sources in the 4K area, there are several 4K movies, but still need money, the rest are not short films are some of the money, the playback is still good, the loading speed is relatively fast
Although there are some movies and TV dramas listed in LG's mall LG STORE, the last way to open it is still the number of Chinese clients, these films should still be the number of Chinese
Strange things happened. In the middle, after I restored the system to the factory, I had a browser function that was somewhat baffling, but I couldn't use it because of your understanding of the reasons. This is a very helpless thing, so it is also broken. The possibility of watching videos directly from web pages. In general, the source of WEBOS is still relatively lacking, mainly because LG lacks its own source and needs to rely on third-party clients. Third parties must pay to be able to watch movies that they want to watch. This is a bit troublesome.
3, software extension
As an operating system, software support is indispensable. If there is not enough software to support it, it is also a device. LGWEBOS has its own application market LG CONTENT STORE
The TV dramas and movies have already said that they are the sources of Hua Digital. LG does not have its own source, and opening applications and games is very disappointing. There are a total of 24 software, of which only 7 applications, except for one Taobao client other applications are useless, and the remaining 17 software are all games, are small games, should all be transplanted from Android, also Nothing to play with.
What is even more tragic is that the APP for TV WEBOS is basically not found on the Internet. Even though there are apps for WEBOS that were created by WEBOS enthusiasts 13 years ago, none of the application websites is specifically developed for WEBOS. The client, more depressing is that although there is a WEBOS website on LG official website, but the program inside is still the same as that provided by the TV system, there is nothing worth downloading.
4, smart sharing and video playback
One of the biggest features of WEBOS is plug-and-play external devices, without installing drivers or setting anything.
U disk directly to the USB interface, the TV can immediately display the contents of the U disk, and the most important thing is that he does not like the Android system to go to the folder one by one to find the files you need, but Automatically categorizes files , including photos, videos, and music
U disk pictures can be viewed directly
You can zoom in and see, this picture is 1920×1080, so after doubling the size, it's just 4K in the size of 3840×2160.
WEBOS has a simple picture editing function that allows for simple editing of pictures
But I don't know why I can't use it after it is turned on. The remote control cannot select that OK button.
But you can edit the photos in the device connection. The others cannot be changed.
The system can directly play the files in the U disk. I put the 4K file, the play is very smooth and there is no stall, you can use the forward and back, and pause play buttons on the remote control to operate, instead of selecting on the screen . In addition WEBOS support for video formats is also very wide, basically the mainstream video formats can play
WEBOS can also read files from a USB drive like Android and Windows, but it cannot be edited.
5, device connection
WEBOS supports plug-and-play for multiple devices without installing drivers. Most of them are connected through the HDMI interface. This is the most convenient function I use.
However, mobile phone sharing requires a client to be installed on the mobile phone. However, this client only supports Android, but it is not available on IOS.
For the mouse and keyboard can also be plug and play, two USB interfaces also just let the mouse and keyboard can be used at the same time, but this TV does not have Bluetooth, it can not use a wireless mouse.
Eight, summary
advantage:
1, the value is very high, the gold narrow border looks very atmospheric, but also very thin; even the back is also very beautiful design
2, the interface is complete, especially the USB3.0 and ARC HDMI1.4 interface can basically meet the needs of home
3, the screen color is very beautiful, the color is also very positive
4, the viewing angle has been the characteristics of LG's IPS screen, almost reached a viewing angle of 180 degrees, and viewing at a large angle will not have much difference in color
5, WEBOS operation is very concise and very convenient, there is no such a layer of Android cumbersome
6, very like the intelligent sharing function of WEBOS, almost all devices can plug and play do not have to set what, also supports the mouse and keyboard plug and play, very convenient
7. WEBOS can automatically identify and classify files on external storage devices. It is not necessary to go to folders one by one like Android.
8, WEBOS supports very good video formats, playing 4K files is also very smooth
Disadvantages and suggestions:
1, LG quality control of the product or to be strict, like this loose screw really should not appear;
2, accessories are a bit less, although other brands also rarely send a lot of accessories, but I still want to be able to standard with some wire, especially the HDMI cable on the market this kind of uneven wire
3, LG's dynamic remote control is more like, since the so-called 4K flagship TV is not worthy of the best remote control is a bit disappointed
4, heat a little problem, no use how long ago the bottom left corner of the metal frame on the hot can not touch
5, electronic switch can not be completely off, after shutdown is always standby power consumption
6, delay and smear problem is a common problem of TV, so do not want to use this TV as a monitor
7, the most let me disappointment is the light leakage problem, although the LCD screen has a light leakage problem, but this Taiwan's light leakage has seriously affected the viewing effect, I do not know if this TV is a special case or LG's quality control really Decreased
8, WEBOS's shortcomings are also very obvious, the film source completely relies on third parties, 4K TV does not have 4K source, can install more than 20 software, application software is no more than 10, no matter how good the operating system No application support is also ah
9, connecting to the phone requires the client, but there is no Android only IOS
Conclusion
Overall, the 49UF6600 is still a TV with fairly balanced performance. The full interface plus plug-and-play features of the WEBOS system are very handy when connected to external devices. However, on the screen, it still does not reach my consistency with LG. The high expectations, delays and smearing problems are the shortcomings of TV. There is no way, but LG's proud screen is not satisfactory. The light leakage problem on the screen is very disappointing to me and has affected the viewing effect. . As for WEBOS is a very good system, but unfortunately its three owners did not have enough investment in it, resulting in very few WEBOS software, for smart systems without software support that can only be a decoration, and hope LG Can increase the support for WEBOS software development, otherwise people who like to use WEBOS only feelings. The film source construction is now domestic brands do better than foreign, LG completely rely on third-party film source that is equal to no source, and if not WEBOS can not find their own software installation, or optional third party There are still many sources. If you buy WEBOS TV or prepare a box for yourself.
