Toshiba 46vl753

Pictures look terrific whenever fed the right sort of content, but at other times they're let down by a single, but hugely irritating, flaw: inconsistent backlighting.

This manifests itself during dark scenes as multiple areas of varying brightness. There's a little pool of extra brightness in each corner, for instance, but also two or three others that appear over central parts of the picture, throwing up a wall between you and any dark scene you're watching.

These areas of extra brightness are completely invisible if you're watching predominantly bright footage, but few TV dramas or films get by without any dark scenes. So it's clear that the backlight issues have the potential to occasionally distract you from almost anything you watch.

Obviously, you can reduce this problem by toning down brightness and decreasing the backlight presence, but while doing so can reduce the issue a little, it doesn't sort it out completely.

Backlight inconsistency is, of course a common issue with edge LED TVs, but there are many sets that suffer from it far less grievously than this one.

Making this single flaw all the more annoying is the amount of stuff the TV gets right in other areas of its picture performance. Colours, for instance, are vibrant, well saturated and natural in tone – at least after a little time spent removing a slight yellow bias from the out-of-the-box settings. There's enough finesse in the way the set renders blends and shifts, too, to stop skin tones from suffering with the slightly patchy, waxy look often noted with flatscreens.

The 46VL758's black level response isn't as bad as you might imagine. Predominantly bright images with a bit of blackness in them are punchy and dynamic and dark scenes would be convincing were it not for the inconsistent backlighting.

The set is a fair handler of motion, with the100Hz engine operating in conjunction with what's presumably a pretty speedy innate panel response time enable it to avoid many of the blurring woes to which so many LCD screens are prone. There's a little residual judder, but this is seldom truly distracting.

The lack of motion blurring makes it easy to appreciate the 46VL758's enjoyably sharp, clear and detailed rendering of high-definition sources and the sterling work done by Resolution+ with standard-definition pictures. Just don't set the latter higher than its two or, at a push, three as doing so introduces unwelcome amounts of noise and grain.

One noteworthy shortcoming sees the screen's contrast reducing dramatically if you have to watch it from an angle of 30º or greater off-axis, while another is that the glass panel that gives the TV its 'one layer' finish tends to reflect ambient light – especially if you've got any wall lights sat directly opposite the screen.
