Eco-technologies in lg TVs. General settings How to turn off power saving on lg tv

With global warming threatening to have a devastating impact on the planet, environmental issues now concern everyone. Public authorities in many countries are taking serious steps to reduce carbon emissions by setting new standards for energy consumption.

Thus, in the first budget of the new US President Barack Obama, ambitious plans are proposed to overcome the effects of climate change through the development of "green" technologies and cleaning technologies, as well as the development of renewable energy sources. Through voluntary programs such as the EPA Energy Star, electronics manufacturers in the US are being encouraged to develop more energy efficient products.

In the past, only large household appliances such as refrigerators and heating systems were considered the largest energy consumers in our homes, but today there are many electronic devices which significantly increase energy bills. The most energy-consuming device is the TV. As reported in the Chicago Tribune (http://www.chicagotribune.com/features/lifestyle/green/chi-0301-smartgreen-homemar01,0,961525.story? page=1), there have been more than 50 -percentage increase in the share of TVs in the total amount of electricity used at home. This is mainly due to the growing popularity of large-screen TVs along with the increased use of TVs themselves compared to the past decade.

Since the television is now recognized as one of the main household electrical appliances, manufacturers of these devices feel a greater responsibility to design energy-efficient and environmentally friendly products. According to research firm DisplaySearch, approximately 70 percent of global flat-panel products will have green features by 2012, up from 20 percent in 2008.

LG Green Technology Developments

As a leading manufacturer in the global flat panel display market, the company is actively working to reduce the power consumption of its TVs by developing innovative energy-saving features. Such eco-friendly energy-saving improvements in LG TVs have led to successful results. At this year's CES, LG introduced new line TVs with advanced Smart Energy Saving features (innovative energy conservation), as well as the thinnest LED TV in the world with local dimming technology.

Main Feature Smart Energy Saving Plus is an Intelligent Sensor feature that analyzes surroundings and light to precisely adjust the backlight of your TV. The Intelligent Sensor controls brightness to improve image quality and cause less eye strain. By reducing unnecessary brightness, energy is saved. In addition, the menu also includes the ability for the consumer to independently select the power consumption mode (minimum, medium, maximum, without video (video mute) depending on the content being viewed. LG TVs save energy up to 70 percent.

LED backlight control together with local dimming reduces power consumption by dividing the TV screen into 200 different sections, which can automatically control the backlight and adjust individually to create clearer and more natural images even when bright light and deep hues are present on the screen at the same time. . Another innovative Standby Mode Zero feature uses a switch to put LG TVs into a power saving mode that uses zero power. This ultimately allows users to cut down on unnecessary electricity bills.

The development of TVs is in line with LG's strategy of focusing on product sustainability, value for money, quality, design, manufacturing, use and disposal. This is a consistent way to eliminate the dangerous effects of the product on environment. The company not only reduces the use of harmful substances in its products, but also implements an assessment life cycle product, which is carried out at each stage of production, in order to assess the impact of the product on the environment. This guarantees the sustainability of each product and contributes to the improvement of product quality and functionality.

With these enhancements, LG consumers will not only enjoy beautiful images while saving significantly on their energy bills, but will also help save our planet.

The European Commission recently announced the release of new guidelines to classify the energy consumption of televisions so that unscrupulous manufacturers can no longer supply these devices to Europe. All TVs will now be accompanied by an energy consumption icon in the same way as dishwashers and refrigerators. These standards will not only help draw attention to emissions issues, but also help consumers make informed decisions when buying new TVs. In the past, only large household appliances such as refrigerators and heating systems were considered the largest energy consumers in our homes, but today there are many electronic devices that significantly increase energy bills.

Design and construction

Externally, the LG 55LA970V is very similar to the rest of the LG TV series, thanks to the overall design of the Cinema Screen. “Ultra-thin” motifs reign here: for example, the thickness of the screen frame is less than 1 cm, there is a metal border around the perimeter. It would seem a completely familiar picture, but it changes a little if you turn on the TV.

It is at the moment of switching on that the LA970V shows one of its main features - a hidden sound panel (similar to a soundbar) comes out in the lower part of the case, which, by the way, sounds very good by the standards of built-in acoustic systems. Accordingly, when turned off, the slide panel retracts back into the bowels of the case. If desired, it can be fixed in a permanently “retracted” position, but after all, few people want to deprive themselves of the pleasure of watching this process every time, right?

Despite such frills, the TV case retained a very low depth - about 4 cm. Naturally, in the lower part, where the sound slide panel is located, the case becomes a little thicker. I would say that the presence of a sound bar did not greatly affect the thickness of the TV - the impression of "lightness" does not disappear. What can not be said about the real mass of the TV, which reaches 30 kg, including the stand. Assembly requires attention, it is not so easy to carefully fit the stand.

The TV stand has an unexpectedly calm design. Korean manufacturers often boldly experiment with this element, but the LA970V stand is quite familiar U-shaped. The design in this case is purely practical functions: The sound slide panel is most conveniently combined with just such a stand.

Interfaces, control and functionality

The set of LG 55LA970V interfaces is absolutely standard. On the back of the TV are 4xHDMI, 3xUSB, a Common Interface (CI) card slot, as well as a LAN network connector, connectors for general and satellite dish and other relevant interfaces. Analog interfaces are made in the form of remote adapters (Y/Pb/Pr and SCART). Most likely, in the foreseeable future, we will stop seeing them altogether.

HDMI 1.4
It's curious that HDMI interface here it has version 1.4, which allows you to transmit Ultra HD 2160p video at a frequency not higher than 30 Hz. Support for 60Hz or 4:4:4 subsampling for Ultra HD/4K signals is out of the question - these are the prerogatives of the new HDMI 2.0 standard. While other manufacturers offer various upgrades to HDMI 2.0 or , LG has no such upgrade planned yet.

USB connectors allow you to connect external drives and play multimedia files - photos, music, videos. Moreover, the number of playable formats is traditionally large - the built-in player, one might say, is omnivorous. It even supports multiple variants of MKV, one of the most popular HD video containers. The interface of the built-in player is quite convenient, the TV effortlessly copes with a large list of files on a connected flash drive or external HDD.

The TV also has a built-in wifi adapter and the DLNA protocol is supported - this allows you to organize a convenient home media library. There is also a special client application cloud service LG Cloud - storage like Dropbox.

As for tuners, the LG 55LA970V is capable of receiving most modern formats: DVB-T2 (digital terrestrial broadcasting), DVB-C (digital cable TV), as well as satellite DVB-S2. The main attention should be paid to the presence of the DVB-T2 standard - this indicates that the 55LA970V is already ready to receive Russian digital television.

LG 55LA970V comes with two remote controls remote control. One of them is an unpretentious push-button remote that fits comfortably in your hand and provides familiar navigation through the TV menu. But for maximum convenience of using Smart functions, LG offers another remote control - the “magic” Magic Remote with motion sensors. I must say that Magic Remote is a very convenient and intuitive way to control, which we fell in love with in previous models.

LG Smart TV

We have already introduced readers to the LG Smart TV interactive system and the Magic Remote in. Actually, the interactive functions on the LA970V model look and work in a similar way, so we will not repeat ourselves - you can read the details at the above link.

Sound

The LG LA970V's sound system is obviously one of the highlights. In addition to the fact that the slide panel effectively "hides" in the body, it sounds quite decent.

Due to the fact that the sound is radiated directly to the listener, it is clearer and more open than we usually hear on thin TVs. Moreover, there is a sane range low frequencies- just enough so that the sound doesn't sound "flat". A good stereo effect completes the picture, giving an improved sense of space.

Let's not draw parallels with full-fledged 5.1 home theaters - this category is still out of reach, but the LG LA970V is a rare case when the built-in TV sound can be used without any regret. Soundbar will provide decent voice acting and broadcast television, and films - dialogues or explosions will not go unnoticed, quite an achievement for one's own speaker system TV. Frankly, we rarely come across TVs with good sound - and here the LG LA970V was a pleasant exception.

Image

As usual, we focus on main function TV - to create an impressive image that would meet all quality standards. To evaluate an image objectively, we use best tests and video benchmarks, as well as pay attention to the calibration of TVs, which allows you to compare them in fair conditions with optimal settings.

Factory settings

The set of picture modes on the 55LA970V is familiar to LG TVs, there are 7 preset modes: Vivid, Standard, Eco, Cinema, Game, and two ISF Expert modes, which are designed for professional calibration. About everything in order.

"Bright" and "Standard" modes by their nature are more suitable for a store. The image here is very bright, but the overall hue is too cold, which negatively affects the color reproduction. In addition, excessive contouring leads to many artifacts in the image. Much better for home viewing use the "Cinema" mode, which, as the name suggests, is for watching movies or TV shows. But here, too, there are flaws.

The default brightness is 236 cd/m 2 , which is more suitable if the TV is placed in direct sunlight. Otherwise, the brightness of the backlight can be safely reduced by almost half - and the eyes will be less tired, and the image will be better.

Gamma in Cinema mode is quite linear, but the average is 2.05 instead of the optimal 2.2. Obviously, this setting is more suitable for daytime viewing, in the evening the image will seem too "whitish". The midtones appear brighter than they should, so the shadows lack depth.

The average color temperature is about 7000K, the image goes into a cold tint.

The color balance is uneven, and this is especially true for dark gradations. The magnitude of the imbalance can be estimated through the Delta E color deviation: the average error is about 6.77 units. The distortion is quite large, the setting could be better. For example, it showed more accurate out-of-the-box settings and a more even color balance.

The color gamut of the LA970V complies with the Rec. 709 (HDTV). But the accuracy is acceptable only at the borders of the range at 100% color saturation. The average color rendering error expressed in Delta E is 3.38 units. Alas, the boundary range does not yet reflect the whole picture.

The evaluation of colors at 0-75% saturation shows that at these intervals the color rendition is distorted significantly more than at maximum saturation. It is obvious that many colors are shifted in hue. Delta E errors often exceed the 5-unit threshold, not a particularly enviable result.

Evaluation with the standard 24 ColorChecker targets gives better results with an average Delta E error of 3.62 units. This suggests that the color reproduction of the "Cinema" mode is at an acceptable level - an inexperienced viewer is unlikely to notice large distortions, but they are still present. In any case, among the proposed set, the "Cinema" mode is the most adequate.

Eco mode is similar to Standard but uses energy-saving features. The "Games" mode, as the name implies, is designed for dynamic games - it has a lower input signal delay (input lag). True, the lag is still felt and can interfere with a gamer with advanced reflexes. Playing here is not as comfortable as on “fast” TVs with minimal latency.

Of particular interest are the "ISF Expert" modes. In addition to adequate brightness and good basic setting, they have advanced image calibration options that we tried to use to overcome the flaws we found.

Calibration

For detailed customization, the TV has a 2 or 20-point white balance adjustment, as well as a color management system (CMS), in which you can fully adjust parameters such as saturation, hue and brightness of each of the primary (RGB) and secondary colors (CMY) . And if these settings worked as they should on previous LG models, then in the case of the LA970V, we stumbled upon outright bugs.

The color balance is initially set roughly, and it is problematic to correct it using a 2-point adjustment. The intermediate result could not be called successful. In attempts to smooth the balance using the 20-point setting, it turned out that it does not work in places, and if it does, it regulates adjacent intervals relative to the declared ones!

Further experiments showed that heavy 20-point adjustments to achieve an even gamma and color balance lead to strong posterization of the image - that is, layering of the gradients. Despite the excellent results of painstaking calibration, real images were full of rough gradation transitions. Let me remind you that on the previous tested model - LG 55LA860V - similar problems. Obviously, LG needs to work on fixing the bugs so that the abundant calibration tool works as it should.

Despite some problems, the TV has the potential for a good calibration - and it will not be difficult to unleash it when the settings are fixed. Our foreign colleagues also complained about the color management system (CMS), but when setting up our LG 55LA970V, the problems started even earlier. Needless to say - in our opinion, such flaws are unacceptable for an expensive Ultra HD TV.

Contrast

Black depth is one of the most important characteristics of an image. LG's previously tested OLED TV has generated a lot of hype for its incredibly deep contrast and vivid picture quality. Naturally, one should not expect such a level from an LED LCD TV. Nevertheless, LG LA970V series TVs are equipped with NANO FULL LED local backlight, which works in dynamic mode. Let's see how she copes with her tasks.

If for starting point take a brightness of about 120 cd / m 2, then the black depth on the fill in the entire screen will be 0.012 cd / m 2, which gives the final On / Off contrast ratio at the level of 10000: 1. Impressive numbers and no catch? Naturally, for IPS this is not entirely true.

It turns out that the NANO FULL LED backlight is constantly working in dynamic mode, even if the corresponding option in the menu is turned off. The screen can “pull up” or “extinguish” the brightness of the backlight in a local area, and situations are especially advantageous here when bright and dark gradations do not coexist within one frame. Therefore, the On / Off contrast, to put it mildly, does not quite reflect reality. It is not difficult to extinguish a black fill, hence the overestimated values of the contrast ratio.

A more detailed contrast measurement on a 4 x 4 ANSI checkerboard gives the following results: average brightness of white fields - 118.63 cd/m 2 , black - 0.087 cd/m 2 . Therefore, the contrast ratio within one scene is about 1371:1. By the standards IPS technology this is good result- for example, Ultra HD TV LG 84LM960V had a contrast ratio almost three times lower! However, for modern IPS, the ceiling is a ratio of about 1200: 1. What contributed to the small increase? The answer appeared before our eyes as soon as we turned on the usual contrasting scenes for visual evaluation.

As already mentioned, dynamic backlighting is always on, and the brightness of the scene “floats” with it. As soon as the contrast combination was displayed on the screen, the brightness of the backlight began to decrease in order to improve the depth of black, but details in the shadows also floated into oblivion! That is, the closest gradations near black turned out to be “merged” into a single spot - it is difficult to see any details on shaded objects. Moreover, adjusting the “Brightness” parameter, which is just responsible for the black level in the signal, turned out to be almost powerless here - by raising the brightness, you can worsen the black color, but the visibility of details in the shadows will not get much better. Just in case, we double-checked the gamma and range of the HDMI signal to make sure that clipping (loss of gradations) occurs precisely at the final stage of the display.

It turns out that the poor detailing of the shadows is a constant companion of the TV due to the non-switchable dynamic backlight. Moreover, picky viewers may find it too annoying permanent change screen brightness following the signal. Forced activation of dynamic backlighting can increase ANSI contrast to almost 3000:1, but in this case, shadow detail is reduced even more, and floating brightness becomes more obvious. In addition, light objects on a dark background leave behind a pronounced “halo”, a familiar effect for carpet lighting.

In defense of dynamic backlighting, we can only say that it hides irregularities well - it's really hard to complain about any "highlighted" areas on the screen, especially in the presence of a signal. And, of course, dynamic backlighting greatly helps the IPS panel in displaying more or less deep blacks - after all, this is one of the key weaknesses of this technology, in the fight against which all methods are good. Another thing is that on the alternative VA technology, blacks are initially noticeably deeper, and this is without the help of dynamic backlighting - for example, on previously tested TVs, we saw a static contrast ratio of about 3000: 1 and higher. It turns out that the NANO FULL LED backlight well masks the mediocre contrast of IPS, but still cannot compete in real contrast with VA LCD panels, and even more so with plasma TVs (PDP) or OLED.

Transfer of motion

As usual, the standard Motion Resolution stress test at 6.5 ppf shows about 300 distinguishable lines out of 1080 without additional processing. That is, a dynamic image pretty much loses its clarity. It's not hard to guess that for Ultra HD/4K signals, the loss is even more pronounced - crystal clearness disappears in motion.

Activating TruMotion frame interpolation can increase resolution in motion, but to avoid the "soap opera" effect, TruMotion's "Custom" mode must be selected. If you set De-Judder to 0 and De-Blur to 10 points, you will be able to avoid the effect of unnatural movement on movies. The remaining modes imply forced frame interpolation, so they are better suited for video - for example, for sports broadcasts. However, do not overestimate the capabilities of TruMotion - surprisingly, in many situations, the increase was not as big as one might expect. In addition, ghosting or trails are noticeable on fast moving contours, and sometimes TruMotion processing artifacts - all this in total has a bad effect on dynamic objects.

Viewing angles

The IPS LCD matrix installed in the TV provides wide viewing angles. At different angles, the image noticeably loses contrast, but the colors are slightly distorted. The glossy finish of the screen, however, creates additional difficulties. Various reflections and glare can interfere with the image - the anti-glare properties could be better.

However, if the TV is optimally positioned, the comfortable viewing area will be wide - provided that the viewers will put up with the gradual black out. After all, at an angle, the effect of local illumination disappears.

Image Uniformity

Since the LG LA970V uses a NANO FULL LED "carpet" backlight, the uniformity is acceptable. In any case, there are no obvious “highlighted” areas of the screen here. Our measurements show that there are relatively small variations in brightness over the entire screen area. The largest drop is recorded closer to the edge of the screen, which is typical for all LCD TVs.

The color temperature is quite uniform over the entire area of the screen, no visible color differences were found in any areas. There are no colored "spots" on a uniform background - in this respect, the LA970V performed better than the .

Standard definition (SD) sources

Upscaling signals of standard (read, low) resolution to "native" Ultra HD is a very non-trivial task. Nevertheless, LG LA970V copes well with it. The TV cannot boast of scrupulous contouring - here and there there are artifacts. The scaled image is soft, blurry, as if slightly out of focus. However, this was to be expected with strong scaling from SD to UHD. But in general, the results are comparable to most Full HD TVs, where the area scaling factor is 4 times lower. Contrary to expectations, watching a DVD on a TV with such a high resolution is not such a hopeless undertaking, the image is quite consistent with the original quality of the format.

Deinterlacing has become more challenging task for TV. If the detection of 3:2 or 2:2 cinema is successful, the TV retains the full vertical resolution of the interlaced signals. But sometimes the video mode is mistakenly applied, which leads to certain artifacts and a decrease in clarity. In principle, such situations arose more often during synthetic testing than on real DVDs. It is unlikely that this will become a frequent problem in everyday browsing.

High definition (HD) sources

Starting with the familiar base setting of the LG LA970V, we experienced deja vu. This is something we've already seen on UHD TVs from Sony and Samsung: the 1080p signal in the LA970V loses some color fidelity. That is, even taking into account subsampling, all information does not reach the viewer - and there is a certain irony in this, given that UHD TVs should just attract viewers with increased clarity.

However, the features do not end there. The default color reproduction is satisfactory, but with detailed settings it is very easy to get a negative effect - a pronounced stratification of color on gradient transitions (the so-called "posterization"). It is not possible to fully use the certified ISF Expert modes, which is surprising, because this certificate is included in the cost of the TV.

In the bottom line, we have the following picture: the image is more or less balanced in colors, but the detail of the brightness transitions could be better. In part, the underestimated gamma has a negative effect here - the TV “brightens” the midtones a little. At the same time, dynamic local illumination partially "eats" the details in the shadows. The image simply doesn't have that subtle gradation that is inherent in top-end TVs. For example, it will be problematic to see a bright lantern in a night scene and details in the shadows here. The TV constantly balances between brightness and black depth.

Just about the complex. Programs. Iron. Internet. Windows
