Build Quality & DesignIn this field, the LG LE5310 is kitted-out well, with DLNA connectivity the only notable absence. That said, LG has included an excellent multimedia player that's compatible with NTFS and FAT 32, and which more than makes up for the lack of DLNA as far as we're concerned. It's therefore possible to plug and play files of over 4 GB in size from any external storage device. In our tests, we found that most of our HD videos (whether AVC (x264) or MKV), could be played without a problem. However, there's no support for M2TS and MTS. Subtitles are handled well when separate to the video file itself but they can't be displayed if they're in the container.
For the rest, the LE5310 has everything you'd expect from a standard TV, with a slim casing (4 cm thick), a swivel stand, two USB ports, four HDMI connections and a remote control that's good quality although not backlit. The remote also has a more modern design than LG's older models.
The internal menu is modern and has animated icons that help make it easier to find your way around. The only drawback is that it can be rather slow. On the whole though, it's still satisfactory.
The TV can be easily hooked up to a PC, and with an input lag of 33 ms—or around 2 frames—gamers won't find themselves at a disadvantage. For the rest of you, the input lag bears no real relevance.
Ghosting Time: 11msIn our ghosting tests, the LG 32LE5310 IPS panel came back with an average response time of 11 ms (don't forget: the lower the better). This TV takes 7 ms to get rid of an image displayed on a light background and 15 ms to get rid of the same image on a dark background. In other words, for an average of 11 ms, an object can be seen in two different positions on the screen at the same time. Fast movements can therefore look blurred.
Image Quality: Factory SettingsVery few TVs give decent image quality straight out of the box, but the LE5310 is something of an exception. Unlike many other models, the colours are natural (average deltaE of 3.2) and just have a slight blue tinge (average colour temperature, 8394 Kelvin). What's more, the brightness curve is almost perfect. In fact, it's probably the best picture quality we've seen to date with a TV's factory settings.
Image Quality: Cinema ModeSwitching to Cinema or ISP Expert mode noticeably improves colour reproduction. Our sensor picked up an average deltaE of 2.1, which is getting on for perfect. Remember that the deltaE is the difference between a colour requested by the source and the colour actually displayed on the TV screen. We consider the colours to be reproduced perfectly when deltaE is under 3.
However, the black does become a little less deep (0.23 cd/m²), which in turn pushes down contrast. The LG LE530 therefore has a measured contrast ratio of 878:1, while other models have reached 4000:1 or above.
It's no surprise to see that high definition films are handled well but that SD films are subject to a middle-of-the-road upscaling. The average Blu-ray/DVD player can do much better.
TruMotion 100 Hz does actually improve the smoothness of faster movements without creating too many artefacts or making your favourite movie look like it was filmed on your dad's camcorder. For the best results, we recommend you set Judder to 0 and Blur to 8.
Clouding in our Test Model
Important note: this photo has been enhanced to make the clouding effect more visible in the still shot. The clouds are not actually as visible as this.
Sound QualityUnlike most slimline TVs, the LE5310 produces decent enough sound. There's clearly not enough room in the casing for this TV to ever dream of producing decent bass, but it's fine for watching the news. However, we'd still recommend that you use a home cinema system or a sound bar for the best results, especially when watching films.
Energy ConsumptionThe LG LE5310 is one of the most energy efficient TVs we've seen, consuming just 0.1 watts on standby and 64 watts in use.
- Accurate colours: average deltaE 2.1 in Cinema and ISP Expert modes
- Matte screen keeps glare to a minimum
- Effective TruMotion 100 Hz function
- Good multimedia player
- Low energy consumption: 64 W (in use)
- Black too light (0.23 cd/m²) and low contrast ratio (878:1)
- Clouding apparent in the model we tested
- Remote isn't backlit
The LG LE5310 TV offers good image quality with accurate colours and wider-than-usual viewing angles. However, the contrast level with IPS technology is still too low (878:1). We've seen other TVs do better.
