Panasonic TX-L37E5B review

Upscale 37-inch Edge LED set with engaging smart dimension

TODO alt text

The TX-L37E5B puts on the kind of picture performance that's sadly lacking on too many so-called all-round TVs.

Colour tones across all sources are precise yet subtle, with none of the 'in-yer-face' antics of some LED-backlit tellies, though the merely average black levels do sometimes interrupt the otherwise natural-looking image.

A shot of the cockpit in a Super Constellation plane during Legends of Flight on Blu-ray shows signs of washed-out areas of black, with only major delineations between shades obvious.

Elsewhere we're impressed by the detail from good sources of HD – such as from our test disc Avatar – whose forest scenes are well rendered and involving.

We've seen sharper, but there's nothing to worry about in this regard.

However, the TX-L37E5B is not perfect.

We've not been blown away by Panasonic's frame interpolation tech – called Intelligent Frame Creation – on some of its other LED TVs, but it's sorely missed here.

During a scene from Legends of Flight where a glider flies past a rocky outcrop of a mountain in the background, the latter judders severely, while in a graphics-heavy sequence some brightly lit lines against a pure black background aren't always clear.

Judder is most evident during horizontal camera pans. There's also some blur, though for most scenes it's not a continual problem.

This is footage that contains a lot of challenging sequences, and the TX-L37E5B does do really well, but it's a good value performance rather than a pitch-perfect one.

Fine, bright lines against black backgrounds move quickly and are rendered not spotlessly, but accurately enough for the money – and that's the key.

Blacks aren't pure, but they're almost there.

The judder in Blu-ray discs is actually the biggest problem, and we know some viewers after 'cinematic' pictures couldn't care less about that. What everyone will love is the reassuringly wide viewing angle.

Images from Freeview HD are solid, with a lot less picture noise and jagged edges on show, but the HD broadcasts just don't seem to be as detailed as they should be.

Pointless on BBC One HD lacks any kind of sparkle, but switch to a standard definition channel – in this case the same programme broadcast on BBC One – and the flaws start to creep in.

Covered in mosquito noise and a tad over-saturated, the picture is softer than it should be on a 37-inch panel.

In retrospect the HD performance doesn't seem as bad, though the flaws remain.

DVD upscaling isn't quite as soft as SD (Standard Definition) telly, though a sheen of picture noise lays across the top.

A blast of The Apprentice in HD from VIERA Connect's BBC iPlayer app appears crisp and contrasty, if slightly noisy, with jagged edges, though the only problem with an MKV trailer of Star Trek is that previously spotted film judder.

While it might seem strange to praise the TX-L37E5B for a problem it doesn't have, it's nevertheless quite a shock to see that those LED clusters around the edge of the LCD panel don't lead to an unevenly bright panel, and there's zero light leakage. That's rare – and it's one less thing to worry about in a thoroughly good value picture performance.
