LG LA860 (47LA860W) 3D LED LCD TV Review
LG raises their game with the LA860
Styling and Design
We continued to use the ISF picture mode but now we calibrated the greyscale using the 2-point [tip=WhiteBal]white balance[/tip] control, before fine tuning with the 20-point version. We then used the [tip=CMS]colour management system[/tip] (CMS) to fine tune the colour accuracy, ensuring the image perfectly matched the industry standards.
Once we had calibrated the greyscale, the colour temperature was hitting its target of [tip=D65]D65[/tip], which is represented by the square in the middle of the triangle on the [tip=cie]CIE chart[/tip] above. The triangle itself is Rec.709 and as you can see, al the colours are fitting their targets. There was a tiny amount of under-saturation in red and magenta but the overall errors were all less than one, so the LA860 was delivery a reference level of colour accuracy.
Whilst these numbers pale (pun intended) next to the kind of measurements seen on a plasma or even a VA panel, they're not bad for an IPS panel. The LA860 had plenty of brightness of course, easily hitting our target of 120cd/m2. The overall consistency of the measurements in the ANSI pattern above, reflect the generally uniform nature of the backlight. We found that the Local Dimming worked well on a Low setting, providing satisfying black levels. This setting eliminated any minor clouding that was present with Local Dimming turned off and it improved the black level without crushing detail. Although the screen uniformity was reasonably good, there was some minor panel array banding that was evident in camera pans. It was primarily noticeable in sport, where the camera would pan backwards and forwards over a uniform colour such as a green pitch. It certainly isn't a big problem but if you watch a lot of sport, you might want to bear it in mind.
The SMPTE 133 pattern revealed that the LA860 cleanly scaled 576i and 480i images without any loss of detail or unwanted ringing. It also scored well when it came to video deinterlacing and correctly locked on to not only the 2:3 (NTSC - USA/Japan) format and the 2:2 (PAL - European) format but also lots more obscure ones besides. With our Blu-ray player set to 1080i the display correctly deinterlaced and displayed both the video and film resolution tests. The LA860 also had no problems in showing video text overlaid on film based material and also handled 24p content without any problems. Using the high and low tests on the Spears and Munsil disc we checked the dynamic range an the LA860 performed well. It managed to maintain shadow detail and was also able to go all the way up to peak white; it also showed all the detail in the three primary colour and white in the clipping test. We still aren’t keen on LG’s frame interpolation software and we could never find a compromise between creating cleaner looking resolution and not introducing video-like motion, so we left TruMotion off. However, overall the motion handling on the LA860 was a major improvement on last year.
The LA860 performed reasonably well when it came to gaming and was certainly a big improvement on last year's LG TVs. In previous generations, the LGs have struggled with very high input latency, even in the Game picture mode. This year we measured the LA860 at about 120ms when not in the Game picture mode but a much better 53ms when it was selected. Whilst this will undoubtedly still be too high for competitive gamers, it is certainly low enough for the majority of people and at least LG is heading in the right direction.
- Standby: 0W
The following measurements were taken with a full screen 50% white pattern:
- Out-of-the-Box – Normal Mode: 70W
- Calibrated – Professional Mode: 63W
- Calibrated - 3D Mode: 95W
Picture Quality - 2D
There LA860 could deliver plenty of brightness, without losing detail, so it performed extremely well during day time viewing and it was only at night that the limited dynamic range became apparent. The mediocre blacks on the LA860 we more obvious at night but thankfully the local dimming and some biased lighting helped. Previous generations of LG's local dimming algorithm has resulted in black crush and a loss of detail but these problems appear to have been addressed. In fact even in its highest setting, the local dimming didn't crush too much detail but there was a noticeable halo effect to bright objects on very dark backgrounds. Ultimately we found the Low setting provided the best compromise between image preservation and a reasonably satisfying contrast performance. The only other issue to mention was the presence of some panel array banding manifesting during panning scenes involving solid blocks of colour. It was never a big issue with the majority of viewing but is worth considering if you watch a lot of football. On the plus side, the backlight uniformity of our review sample was very good and whilst this can often be a lottery, it does seem that manufacturers are getting better at addressing this issue.

LG LA860 (47LA860W) 3D LED LCD TV Review
- It would seem that the Korean TV manufacturers are leading the way in terms of TV design and LG's 47LA860 is a good example. The size zero bezel, attractive stand, excellent build quality and superior finish certainly help justify the price tag. The resulting look is both stylish and contemporary and the LA860 would grace any modern living room. There's a good selection of connections at the rear, including four HDMI inputs with support for both ARC and MHL. New this year is the inclusion of a pop-up built-in camera which can be used for Skype video calls. The latest version of the Magic Remote is, well, magic and a real game changer in terms of how users interact with their TV. It's fast, effective, accurate and intuitive and made navigating the smart features easy and fun. The LA860 comes with four pairs of passive 3D glasses although, if you have any RealD glasses from the cinema lying around, they'll work too. There are also two pairs of glasses for LG's excellent Dual Play gaming feature.
LG's latest version of their Smart TV System has already deservedly won a Reference Status badge and shows many other manufacturers how it should be done. The layout is well designed and intuitive, whilst providing a degree of customisability. There is an excellent selection of apps and video-on-demand services, plus extensive networking and media playback capabilities. Along with built-in WiFi and WiDi, LG have added Miracast and their 'Tag On' feature which connects instantly with any device that supports NFC. As is always the case, LG's menu system is well designed, informative and easy to navigate; with extensive calibration controls including a 20-point white balance and a full CMS. The out-of-the-box accuracy was impressive and after calibration, the LA860 delivered a reference performance. The LG includes a built-in 2.1 audio system that whilst no match for a decent soundbar was certainly better sounding than many other slim-line TVs.
The picture performance was solid rather than exceptional but the out-of-the-box accuracy was immediately apparent and the calibrated images really impressed. The motion handling was a big improvement on last year and LG's video processing remains top notch, resulting in really good standard definition images. Overall the 2D pictures were bright, accurate and detailed and our only areas on complaint were some weak blacks and occasional array banding. However the backlight uniformity was good and the local dimming certainly helped with the blacks without crushing detail. The 3D performance was superb, with LG's passive approach proving why it has been popular with consumers, thanks to cheap easy to use glasses combined with bright and accurate images that are free of flicker and crosstalk. Ultimately the LG 46LA860 is a great all-round TV that provides a solid performance and a reference level of smart features, all wrapped up in a very attractive package.
