Sharp LC-37RD2E

100Hz picture processing can't make up for its weaknesses

Our Verdict

We can't recommend a TV with processing that distracts you from what you're watching


  • Neat looks

    Minimal motion blur


  • Processing issues

    Unnatural picture

This TV uses 100Hz image processing, which doubles the usual TV scanning rate to eliminate LCD's bugbear of juddery motion.

Sporting a high-gloss black finish and gently curved bottom edge, it scores high on the connections side, too, with two HDMIs and a PC input among the highlights.

A single irritation stems from the lack of a dedicated component video input. Instead you have to double up on the PC port via a (supplied) adaptor to get component feeds into the TV.

Aside from the 100Hz engine, the set's single most eye-catching specification is probably its 10,000:1 contrast ratio - one of the very highest quoted for an LCD TV, achieved via a dynamic contrast system, whereby the TV's backlight is dimmed during dark scenes to produce a deeper black level. The 'pure' contrast ratio of the panel, without the dynamic contrast system, is a more demure 1,800:1.


Extended use of the 37RD2E reveals a couple of operating glitches: a rather sluggish menu system and a very clumsy, crackly switch between HD and standard definition when watching a Sky HD box set to 'Automatic'.

What's more, we also discovered some real flaws with that key 100Hz processing engine. The set almost over-delivers, with objects moving across the screen so smoothly that the effect actually feels weird.

Sharp's 100Hz engine generates too many distracting side effects. First, fast motion, especially in a diagonal plane, can sometimes shimmer or flicker quite noticeably. Second, some small moving objects can generate bizarre double ghost images.

For instance, during the recent final England v India test match, our misery was compounded by the fact that there appeared to be three balls trundling across the grass. Freaky.

In other ways the 37RD2E's pictures are pretty decent. Colours look likeably vivid and naturally toned, detail levels are generally very high during HD viewing, standard-definition pictures look passable (if a little noisy) and black levels are reasonably - though certainly not spectacularly - deep. The set's audio, too, is pretty sound for a TV with 'hidden' speakers.
