Another interesting connection – though one we weren’t able to test – is the socket labelled Wireless Control. This is designed to take an optional (around £230) LG AN-WL100E external wireless media kit allowing cable-free transmission of sound and full 1080p video from external sources into the TV.
One ‘connection’ the 37LE5900 lacks versus its higher-end siblings is Bluetooth functionality, whereby you could stream photos or video into the TV off mobile phones, or listen to the TV’s audio on Bluetooth headphones. But this is a feature we suspect only a handful of people would really make significant use of; certainly we didn’t miss it much, and we’re supposed to be relatively technically minded versus the general population!
The 37LE5900 gets back to keeping up with the LE7900 series again, though, by sporting a full HD resolution, LG’s TruMotion 100Hz video processing, and perhaps most impressively of all, endorsement from the Imaging Science Foundation (ISF).
The 37LE5900 hasn’t just ‘scraped’ this ISF support either. Its onscreen menus are in fact absolutely stuffed with picture tweaks and features. These include, most notably, gamma adjustment over two or – superbly – 10 points, a full colour management system, and separate standard and MPEG noise reduction systems.
Not all the tools LG puts at your disposal are actually that useful; an Edge Enhancement circuit tends to make pictures look uneven and bitty, for instance, and even the noise reduction routines have to be used with care (or ideally switched off totally with HD sources). Overall, though, LG is to be heartily congratulated for providing so much calibration flexibility at the 37LE5900’s deflated price point.
If you’re the sort of person who either glazes over or feels terrified at the merest mention of in-depth calibration aids, though, don’t worry. For also present within the 37LE5900’s exceptionally well-designed onscreen menus is a Picture Wizard, that walks you through basic picture set up via a selection of test images.
As we settled down to assess what the 37LE5900 is capable of in performance terms, the first thing we noticed was that there was far less evidence of the ‘grey blocks’ around bright picture elements sometimes seen on the LE7900 model we reviewed a while back – blocks caused by that set’s attempt to introduce local dimming to edge LED lighting.
According to an LG contact, the 37LE5900 does still have a degree of local dimming in play, even though there’s no option to deactivate it like you get with the LE7900 series. But we could rarely see its effect – in either a positive or negative way. And actually, given that it was the negatives of the more well-defined dimming system that made the most impact with the 42LE7900, we’re not at all sad not to notice it on the 37LE5900.
The 37LE5900’s pictures are enjoyably punchy too, thanks to rich, dynamic colour saturations and a high level of natural brightness. Colours enjoy mostly decent toning as well – though we found we had to tone down overall saturations and especially the blue element from those employed by the TV’s various preset picture settings before we were happy.
In HD mode the 37LE5900 also delivers decent (though certainly not startling) sharpness and detailing, backed up by some solid-to good motion handling – even with the TV’s TruMotion processing deactivated. Turning TruMotion on reduces judder and marginally improves motion resolution, though we suspect many of our readers will prefer to leave it off, at least when watching Blu-rays.
