It’s important to add here, too, that the amount of brightness you have to take out of the picture to get black colours looking mostly convincing can leave the L37G20B‘s images looking a touch muted and short of shadow detail. Though on the upside, thanks to its use of Panasonic’s In-Plane Switching technology, you can watch the L37G20B from a slightly wider angle than most LCD TVs before contrast drops off severely.
Another area of slight disappointment concerns the image’s crispness, as both HD and standard def material looks slightly softer than we’d ideally like. This is mostly down to residual motion blurring, despite the efforts of the motion compensation processing.
HD pictures still look resolutely HD though, so the issues we’re talking about are only minor. And then there are the set’s strengths to consider. These lead off with a bright and breezy colour palette that combines a decently wide range with arguably the most natural tones Panasonic has managed on a CCFL LCD TV to date. In fact, although pictures lack a little of the punch experienced with Panasonic’s recently reviewed TX-L32D28 edge LED TV, the L37G20B actually has a more consistently authentic colour range.
The L37G20B does a fine job of upscaling standard definition pictures too, as the slight softness we mentioned is compensated for by far fewer colour imperfections than we often find with upscaled LCD standard def images, and impressive suppression of video noise.
The set’s brightness levels are high meanwhile, doing a good job of hiding the slight black level shortcomings during bright scenes like those that make up the majority of normal daytime TV viewing,
The L37G20B’s sound is more or less what we would expect of a 37in flat TV. In other words, it’s nothing to write home about, doing a fair to middling job of producing a reasonably well-rounded mid-range, but lacking the finesse to produce much treble detail and the power to produce much bass.
There’s nothing to really dislike about the TX-L37G20B on a basic TV level. It delivers nice pictures and solid sound alongside plenty of handy features - including those lovely twin Freesat and Freeview HD tuners.
Its main problem comes, ironically, courtesy of its own G20 plasma brethren. For at the time of writing, we managed to find one of Panasonic’s TX-P42G20B plasma screens going for roughly the same price as the L37G20B. And considering that the P42G20B offers not only five inches more screen size but also superior pictures, surely that’s the screen to go for instead?
