Beneath the bonnet of the LE320, the picture processing engine is standard-issue 100Hz, which means no local dimming or scanning tricks to improve contrast or reduce blur. The screen also offers a 'film dejudder' Film Mode.

Picture controls are comprehensive enough for a screen of this size. In addition to the usual options of Brightness, Contrast, Colour, Tint, Sharpness and Colour temperature, there are more options in an Advanced menu.

Here you can choose from one of three noise reduction settings, make a flesh tone adjustment, alter the brightness of the backlight (High or Low) or activate DCR (Dynamic Contrast Ratio).


It's also here that you'll find the settings for the 100Hz refresh rate with variable blur reduction, or Film Mode to decrease picture judder. It's worth noting that 100Hz mode doesn't function on the PC input.

Bizarrely, the Advanced section of the Picture menu has it's own secondary Advanced subsection. An advanced menu within an advanced menu? Someone at Sharp isn't trying hard enough.

To find the set's Overscan defeat, you'll have to navigate to the Features/HMDI Scan Info sub-section of the menu. Here you can select Underscan or Overscan. Curiously, this adjustment is not classified as an aspect ratio, that honour is reserved only for Auto, Normal, Zoom 1, Zoom 2 and Wide modes.

When watching an HD source, be it from a set-top box or Blu-ray, it's always worth selecting an underscan/pixel-matching mode.

It goes without saying that the screen's static resolution is excellent, giving a prickly 1,080 lines. Motion resolution has less snap, though, and while you're given options to mitigate against losses, there's a price to be paid.

The 100Hz processing comes in Off, Low, Middle and High flavours. Set Low, a scrolling motion resolution chart (developed by the Advanced PDP Development Centre) which features an ever-decreasing graticule moving at 6.5ppf (pixels per frame), hinted at detail between 800-900 lines, which can be considered very good. However, this detail is often obscured by processing artefacts.

Edge up to Middle and High and, while more perceived sharpness can be had, the artefacts increase. Switch to Film Mode on Low and they vanish, but the resolution similarly drops away, with nothing much left above 750-800 lines. In 100Hz Effect Off, the result is the same.

To keep this in context though, this should still be regarded as a good performance compared to comparable screens.

The set looks worst with images from its Freeview tuner, which have an unpleasant bleary quality. With a high quality source, such as Blu-ray, the 37LE320's pictures have a pleasing sharpness.

Black levels are good without being exceptional.

Regardless of the anti-judder Film Mode, this panel is naturally smooth. A panning test from the Blu-ray release of Sleeping Beauty, in which Prince Charming gallops behind a rocky outcrop, plays without any stutter or judder.

Indeed, it looks best without the high 100HZ picture processor engaged. At the faster rates, the moving shape of the prince and his horse is surrounded by a smudgy halo artefact. Regardless of mode, there always seems to be a hint of image blur around fast moving objects.

On the plus side, colour fidelity is good. Hues pop off the screen and a test sequence comprising violins, horns and saxophones looks rich and textured. There's lustre to the wooden finish of the violins and a gleam to the brass instruments that is definitely satisfying.

As you can see above, the LC-37LE320's edge-LED backlight is a little uneven, but not woefully bad. You'll most likely only notice when the screen sporadically fades to black or you're watching a letterboxed movie.
