Anyway, as noted earlier, having already covered the whys and wherefores of white dimming direct LED technology in the review of the 40LE600E, it's arguably the 46LE700E's 100Hz processing that's its most significant trick. For if its process of doubling the image refresh rate really can magic away the sort of innate response time-related blur problem noticed on the 40LE600E, it has the potential to make the 46LE700E a great TV rather than just a good one.
Delving into the 46LE700E's reasonably well-stocked, solidly presented onscreen menus, you find a reasonable collection of adjustments. The most significant of these is a really quite sophisticated colour management system, but there are also a variety of noise reduction settings, an always-appreciated variety of gamma settings, and the option to turn off the 100Hz system. This latter option might sound a bit daft on paper; after all, if you don't like 100Hz processing, you might as well save a few pounds and go for the LE600E range, right?
Actually, though, it's not quite as clear cut as that. For my own personal experience of 100Hz processing systems is that while they might work great for some types of source, they can generate a few distracting artefacts with others. So providing the flexibility to turn a 100Hz system off and on as I wish is actually pure common sense.
After such a big build up, though, I have to say that the 46LE700E's 100Hz engine turns out to be something of a disappointment. For no matter how much I tinkered with the picture's settings, I couldn't manage to rid the picture of as much motion blur as I would have liked.
To be clear about this, I'm not saying that the 100Hz engine is completely ineffective; motion actually does look slightly sharper and more detailed than it does on the 40LE600E. But the system isn't quite potent enough to achieve the same level of blur suppression it does on many rival LCD TVs these days. So while the 46LE700E is incrementally better than the 40LE600E, I still can't in all honesty award it with one of TrustedReviews' Recommended awards.
I also must point out that very oddly, the 100Hz on/off option isn't actually available as an option when you're watching 24p Blu-ray feeds. While some TVs switch to a different processing mode with 24p content, I can't think of a single other TV where the 100Hz engine option is just flat-out disabled with 24p playback. Though feel free to bombard me with examples in the Comments section of this review if I'm wrong!
