Review LG 55EC930V: unique curved OLED-TV – Mail.Ru


     

     


     

The technology of OLED (organic light emitting diodes) in theory ideal for creating screens. That’s just a long time we have seen it only in small mobile devices or experimental TVs. With a light feeding of LG OLED technology gradually ceased to be exotic, when it comes to 55 inches diagonally.

These TVs are commercially available since last year and uncommon cause “wow effect” perfect contrast and a minimum thickness of – we talked about this in the review of LG 55EA980V. A year later, the price dropped by 2.5 times, and, apparently, LG is preparing for a serious assault on the mass segment. In this new version is designed to help the 55-inch OLED-TV – LG 55EC930V, which is dedicated to our review.

On the test model was LG 55EC9300 specifications for the US market. The official model for Russia and the CIS – LG 55EC930V, the average price – 160 700 rubles.



Design and construction

The base housing OLED-TV series EC930V, in fact, remained unchanged. Curved 55-inch display has a thickness of only 4.3 mm, excluding a portion where the filling contains TV. This is still the most subtle and elegant TV with a screen size.

The main difference from previous versions – a stand. “Crystal” clear stand gave way to the metal “legs” smooth shape, it is better protected the TV from tipping over. And most importantly – new curved OLED-TV can now be hung on the wall, this includes securing the special design, which are sold separately. With their help, the TV can priladit on standard bracket VESA.

Modification EC930V impressive as previous versions. Let the carbon trim and a spectacular transparent stand is in the past, television has become more practical. Suitable for wall mounting, in our opinion, would have come in handy.

interface, control and functionality

The set of interfaces LG 55EA980V quite standard. Rear of the TV are located 4xHDMI, 3xUSB 2.0, a slot for Common Interface (CI), as well as the network connector LAN, connectors for general and the satellite dish and other relevant interfaces. Analog interfaces Y / Pb / Pr and SCART made in the form of extension adapters.

As for the tuner, the LG 55ES930V able to accept most modern formats: DVB-T2 (Digital Terrestrial Broadcasting), DVB-C (digital cable TV) and satellite DVB- S2. The main attention is paid to the presence of the standard DVB-T2 – it says that EC930V already ready to receive Russian digital TV.

Complete LG 55EA980V comes two remote controls. One of them – a lowly button remote that fits comfortably in the hand and provides the usual navigation on the TV menu. But for maximum ease of Smart-functional in LG offers another remote – “Magic» Magic Motion with motion sensors.

As before, Magic Remote provides intuitive and responsive cursor control. WebOS interface is well suited for moushen-control, so use the remote control is very convenient. The remote has a built-in microphone for voice search and typing. Overall, Magic Remote – an indispensable thing for “smart” TV.



LG Smart TV (webOS)

We are already familiar with the interactive system LG Smart TV based on webOS in the previous review LG 65UB980V. A similar platform is used in the OLED-TV LG 55EC930V. All benefits at a glance: multitasking, accessible interface, a variety of applications, functional browser, and so on.

The system webOS offers a lot of opportunities, and the only gripe concerns the speed of work: If running multiple parallel processes, the system performance decreases. However, it is inevitable cost of freedom to “turn off” processes and return to them – such multitasking is still not on the other TVs.



Sound

The sound system of the new model EC930V simplified. Speakers moved into the housing of the TV, the sound is output in the form of reflection, so it is flatter and “squeezed” than the previous version with the speakers in the stand. However, in any case, built-in sound is not amazing. Such TV is definitely worth to buy an external audio system – the good, the choice here is huge.

Image

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



Factory settings

Picture Modes 55EC930V similar to other TVs from LG – there is, to choose from. It offers several preset modes: “Vivid”, “Standard”, “Eco”, “movie”, “Games” and the two modes «ISF Expert”, which are intended for professional calibration. Curiously, THX certification at OLED-TV was gone, but, in practice, this is not an indicator. For example, the mode is “Movie” and without special certificates may please the appropriate color reproduction.

The average gamma – 2.1, which is slightly below the optimal range of 2.2-2.4. Image slightly lightens, this configuration is more suitable for daytime viewing.

The average color temperature – about 7000K.

The color balance is not perfect, there is an excess of blue components. Average Delta E color error on the gray scale – 6.55. Setting is not ideal, but deviations are not that big. One can only note a small bias in the cold tone image.

The color gamut conforms to Rec. 709 (HDTV), and, with good accuracy. The standard palette gives the optimum color saturation, and an additional “richness” is achieved through outstanding contrast OLED.

The situation inside the gamut shows that the deviations are also kept within reasonable limits.

Overall rating of 24 color patterns ColorChecker gives good results: the average error Delta E – 3,27 units.

It turns out that preset mode “Invictus” and the truth is ideal for watching movies. However, television is able to do even more – try to squeeze the maximum out of it with the help of the calibration.



Calibration

Setting the OLED-TV – is not easy, in that we have seen on the example of the previous generation. Color balance and brightness of the image depends on the brightness of the frame, so many indicators of “float” in real time. But, as it turned out, the volatility image – it’s flowers over its treatment.

Despite the huge number of settings for the calibration menu EC930V, including a 20-point white balance, the nicest way to set up – not to touch anything. More precisely, do only the necessary changes. If not actively affect the 20-point white balance, gamma and brightness panel – that blue is significantly distorted, the result only hurt the image. In general, at the moment most of the settings does not work in the best way, and it is subject to software patches. We met something similar on LG 55EA980V, but then it does not express so much.

As a result, the calibration mode «ISF Expert” has been reduced to setting the white balance on 2-point and a small correction of brightness of colors in the CMS. That was enough to get a very decent color.

The average gamma after setting – 2.24 (2.4 at the selected preset in the menu). The adjustment range is small.

The color balance after calibration, is not satisfactory. The average error of Delta E fell from 6.55 to 1,2.

The color gamut further align. Intermediate gradations into place.

The average error on a ColorChecker Delta E decreased from 3.27 to 1.29. With natural colors no problem.

The findings are similar to the last time: OLED-TV LG 55EC930V very specific behavior when a calibration is needed here is very neat approach. Even better would be if the LG engineers debug the expert settings in the ISF modes and eliminate some roughness that of the TV really could get the most. He deserves it!

Contrast

Contrast – by far the most successful category for OLED-TV. In this respect, it is somewhere in your league, as no other technology capable of providing zero black. In fact, the black pixels OLED is completely turned off, and the reflectivity of the panel is not too high. Therefore, OLED-TV provides a fascinating contrast in the dark and in bright light, making the image very deep and lively. The measured contrast ratio formally tends to infinity.

If the black color with all clear and without further ado, it is worth noting that the brightness of the OLED-TV – not so constant. If the image has a lot of white color, the overall brightness is reduced. Brightness fluctuations, anyway, you can see and test video and real video. Such nuances and we celebrated on LG EA980V. However, the brightness of the stock is so large that the problems with daytime viewing will not. I would like only to adjustment “on the fly” was smoother and more veiled.

The transfer of motion

Technology LG OLED, despite the fast pixel response time, using the method of updating the panel, similar to the liquid crystal. Therefore, in the motion picture “eroded”, the visual effect is not much different from the LCD. The standard stress test Motion Resolution default distinguishable only 300 lines of 1080.

A little system helps improve the interpolation of intermediate frames TruMotion. Engage the “clear” or “smooth”, you can increase the resolution in the dynamics of about 600 distinct rows. At that appear and unwanted artifacts processing, and the effect of “soap opera” in the movies … In general, the transmission of the movement remains one of the problematic sides for OLED.

Viewing angles

The Matrix Organic Light Emitting Diode (OLED) give angles fundamentally better than any kind of liquid crystal panels. Each pixel matrix OLED emits light uniformly in all directions, so at different angles luminance and chrominance image looks about the same. In this regard, OLED TVs are similar to plasma. Curved screen helps reduce unnecessary reflection in the screen, OLED-TV LG EC930V looks great at different angles.

The uniformity of the image
