What is the LG EC930?
What is OLED?
So if they're that good, why haven't the shops been flooded with them? Well the simple answer is that they have proved very difficult to manufacture and, until recently at least, expensive to make. Last year there were two competing types of OLED technology, one that used red, green and blue OLEDs and one that used a white OLED and red, green and blue filters. The former was championed by Samsung and was used in their KE55S9 OLED TV and the latter was championed by LG. Samsung have since withdrawn from OLED production, leaving LG and their WRGB technology with the OLED market largely to themselves. You can read more about the technology behind OLED in his handy article and you can read about the advances LG have made in OLED production here.
Design & Connections
The screen itself has a 10mm wide black border and there's a silver trim around the outer edge, whilst the rear panel has a gloss black appearance. The clear plastic stand that was used on the previous generation has gone, replaced with a new design that uses a rather attractive metallic finish. There are speakers positioned along the bottom of the panel and the stand has been designed to enhance the audio performance. The stand doesn't swivel but it can be detached and the EC930 wall mounted if you so desire. At the bottom centre of the panel there is an illuminated LG logo (which you can turn off) and the remote control sensor and the intelligent sensor; whilst at the rear right is a small joystick control.
Features & Specs
The EC930 also includes LG's Cinema 3D, which is their name for passive 3D. As such there's an invisible polarised filter on the front of the screen and the TV comes with four pairs of polarised glasses (two regular and two clip-on). Although as always, if you have any RealD glasses from the cinema knocking about, you can use those as well. Other useful features include the previously mentioned Magic Remote, the free remote app, the Freeview HD and satellite tuners, built-in WiFi, four HDMI inputs with support for ARC and MHL, Miracast and WiDi. There's also a 2.1-channel speaker configuration with 40W of amplification.
As a happy by-product, it also reduces the amount of energy your new OLED TV uses because we measured the Standard mode at 198W whilst our calibrated setting was only using 85W. This is because the Standard mode was also far too bright and would definitely be uncomfortable to watch at night. As an indication of of how bright the Standard mode was, our calibrated 3D mode which we wanted to be bright, was only measuring 162W.

As mentioned in the previous section, we chose the ISF preset for our initial measurements and as the graphs below show, the out-of-the-box performance was excellent. In terms of the greyscale all three primary colours were measuring at about the same amounts at each 10 IRE point from 0 to 100, resulting in overall errors that were below the visible threshold of three. The gamma curve was also quite good, tracking between 2.2 and 2.4 and averaging around 2.3, which is perfectly acceptable.
The colour gamut only has two options - Standard and Wide - but we found that Standard measured close to the industry standard of Rec.709. As the CIE Chart below right shows, the colour temperature of white is hitting its target for D65 and the saturation and hue measurements for the colours are also very good. The luminance measurements were slightly high for all the colours but the overall errors are mostly below the visible threshold of three, with the exception of red and magenta.
It's just as well that the out-of-the-box performance of the EC930 was so good because the calibration controls proved to be something of a disappointment. LG have included both a two-point and a twenty-point white balance control but given the overall accuracy of the greyscale, there was little the two-point could add. However when we tried to use the twenty-point to fine tune the performance we found that it didn't work correctly. The controls for one IRE point would instead affect the one next to it, so for example 20IRE was affecting 30IRE and so on. We also found that using the white balance control introduced errors and in the case of 80IRE we were unable to correct them because none of the controls seemed to affect that point. In the end we gave up and decided to just use the out-of-the-box settings.

LG 55EC930 Video Review
LG 55EC930V Picture Quality
As some people have pointed out the black frame insertion has been dropped but LG has added an hour counter and according to the one on the review sample it had done 106 hours; we were also using software version 04.32.20 at the time of the review. It is also true that the best no sharpness setting is 10 on the Sharpness controls. The EC930 uses exactly the same 'sample-and-hold' approach that we saw with the EA980, which means the panel displays and holds a static frame until the next one is refreshed. As a result the EC930 was delivering about 400 lines of resolution with TruMotion turned off. This could be improved by turning TruMotion on but the result is a picture that looks unnaturally smooth, especially with film content, and we could see artefacts in some of test material. This was true regardless of whether you choose Smooth or Clear and although you could experiment with the TruMotion settings on something like football, we were perfectly happy watching all of our content with TruMotion turned off.
As we mentioned in the calibration section, the calibration controls were very buggy with the 20-point white balance created more problems than it solved, whilst using the CMS resulted in terrible colour artefacts. Thankfully the out-of-the-box performance was excellent and so the EC930 still delivered natural and realistic looking colours, whilst the greyscale and gamma performance was also very good. There were also no signs of clipping in red, green or blue; whilst we could see all the detail up to video level 255 and down to video level 17. There have been reports of backdoor video processing, especially noise reduction, removing grain and high frequency detail on the EC930. Well we turned everything of and watched test footage and various films, like the beginning of Casino Royale, with excessive grain. We could clearly see the grain and there were no signs of any noise reduction being applied; whilst high frequency detail in our test patterns certainly appeared to be present and correct.
It's possible that LG has addressed these issues with a firmware update or the affects are too subtle for most people to see but we doubt your average consumer is going to find issue with the images produced by the EC930. Certainly when watching Blu-rays the images appeared highly detailed and clean, except in the instances where film grain was supposed to be apparent, and there was no sense of high frequency information being lost. Overall the video processing was very good and the EC930 had no problems deinterlacing and scaling standard definition content, with excellent detail and no unwanted ringing. It also had no problems detecting both 3:2 and 2:2 cadence correctly or handling scrolling video text over film. The LG performed equally as well in the other tests, delivering an excellent performance. The quality of the video deinterlacing at 1080i50 was just as good as it was for standard definition and there were no apparent issues with 24p content.
We watched a lot of content on the EC930, thanks to a totally coincidental holiday, and we were never anything but impressed by the pictures it produced. The BBC's new documentary series Life Story looked absolutely spectacular in high definition and so did a number of Blu-rays that we watched. Gravity gave the EC930 a chance to show off its massive dynamic range with white spacesuits against black backgrounds, whilst the final Harry Potter film revealed the remarkable contrast ratio and shadow detail. When watching films like X-Men: Days of Future Past and Pacific Rim the detail was excellent, whilst colours remained natural and vibrant even in darker scenes. The 3D performance was also superb and although the use of a polarised filter does reduce the resolution it really isn't apparent at any sensible viewing distance. However what was apparent was the brightness of the 3D and the complete lack of flicker and crosstalk.

LG 55EC930V (EC930) OLED TV Review
Should I buy one?
If you're in the market for a Full HD OLED TV then the simple answer is yes because at £1,999 you'd be crazy not to buy one. The 55EC930 isn't quite as impressive as the 55EA980 that we reviewed at the start of the year and there are a number of issues that prevent us from awarding a Reference Status badge. Unfortunately the calibration controls are largely ineffective, although thankfully the out-of-the-box performance is excellent. Aside from that though, we feel that complaints about motion handling and backdoor noise reduction have been somewhat exaggerated and we had no issues with screen burn or dead pixels on your review sample.
The simple fact is that the LG 55EC930V is a gorgeous TV with a fantastic OLED panel that delivers unbeatable blacks and contrast ratios. The colours are natural, the 3D performance is excellent and the overall picture quality was superb. As always the curved screen will come down to personal preference but we hardly noticed it during testing and the viewing angles are very wide. The panel has plenty of brightness and a huge dynamic range, whilst the input lag will be acceptable to most people and the sound quality was surprisingly good. Once you throw in the Smart+ system with webOS and a host of other features, you've got yourself an easy Best Buy.
What are my alternatives?
As far as OLED TVs go LG is the only game in town at the moment, which does rather limit your options. However even if there were other makes to choose from, you'd be hard pushed to find a 55-inch OLED TV for less than £1,999. In fact you'd struggle to get a flagship LCD TV for that price, so the only real question is do you go for Ultra HD 4K instead? Once again the only manufacturer even talking about 4K OLED is LG and it doesn't look like we'll be seeing that TV this year. However even if you're thinking of an Ultra HD LCD TV, you wouldn't really benefit on a screen of this size and it's going to be a long time before there's a serious amount of native 4K content. Frankly if you're looking for the best picture quality currently available, then you should be looking at the LG 55EC930V. Oh and did we mention it only costs £1,999?
