LG 42PX5D review

The screen has also been fitted with an upgraded version of LG's own 'XD Engine' chip, which claims to enhance low-resolution analogue signals to high-def levels. In reality, this function only appears to boost black levels and colours but hardly elevates images to high-def quality.

Another relatively unique and more useful feature is the 'X Studio' function that provides quick and convenient access to digital images and music from a multitude of memory cards. Digital camera owners can share, view and edit JPEG pictures on a large screen and even accompany a slide show with music from an MP3 player -- showing off your holiday snaps may never provoke groans from your friends again.

The on-screen display system, which simply involves uncomplicated scrolling through clear, concise menus, is fool-proof. Operation is eased by an intelligently arranged remote that reserves most space for commonly used controls. There are plenty of picture and sound adjustments to play with but not all are effective or easy to access.

Various preset modes offer convenience, but the absence of any short-cut keys means you have to enter the menu every time you change mode. And although menus are vaguely transparent, they don't disappear and tend to obstruct the screen while you make changes. Similarly, despite a button being designated for the purpose, we were unable to instantly access 'Now and Next' digital programme information without first entering the electronic programme guide. These are only slight limitations, but ones that can prove tiring over time.

Extracurricular features include a sensor that supposedly adjusts picture settings according to ambient brightness. But, unless your living room is exposed to extreme light changes, the effect is too subtle to notice. And the same can be said for some of the sound presets, which includes a pseudo-surround SRS mode.

Performance
While the LG 42PX5D's picture performance won't threaten class-leading screens, it's nonetheless commendable -- especially when you consider the price. For at least £500 cheaper than an equivalent Panasonic or Pioneer, you'll struggle to find better value for money.

Unsurprisingly, edgy and unstable analogue broadcasts are best ignored in favour of Freeview. Digital TV images appear far more settled, displaying bright, controlled colours with fine detail and depth. And, provided you allow enough space between you and the screen, typical plasma picture flaws remain inconspicuous.

High-definition performance, gauged by connecting an HDMI-compatible DVD player (the Denon DVD-2910) using an upscaled 1080i signal, undeniably improves image quality above its analogue equivalents. Deep black levels expose intricate detail and superb, depth-defining contrast while beautifully balanced colours comfortably separate natural and superficial shades without confusion. However, the picture is occasionally disturbed by digital artefacts and staggered slow movement that other, admittedly more expensive, screens cope with better.

And that's the rub. If you want to spend less you can expect some compromises. But the sacrifices to usability and image quality are small compared to the significant monetary saving the LG 42PX5D offers.
