Toshiba Regza 46XV635D 46in LCD TV - Toshiba Regza 46XV635D
More good news concerns the 100Hz engine, which undoubtedly helps the 46XV645D reproduce motion with greater clarity than its cheaper stablemates, especially if you're watching sport. What's more, the 100Hz engine does its work strikingly cleanly, with practically no discernible processing side effects for 99 per cent of the time.
I've noted that some cheaper Full HD Toshiba TVs with Resolution+ processing have tended to look a bit soft with HD. But this certainly can't be said of the 46XV635D, which presents Blu-rays and HD broadcasts with admirable clarity and detail (so long, at least, as you deactivate all the set's noise reduction circuitry) without over-stressing edges or leaving the image looking unduly gritty.
In fact, the 46XV635D' s pictures sail dangerously close to bagging a 9 out of 10 for its money; at their best challenging the pictures of 46in TVs costing hundreds of pounds more.
But it's sadly let down by a couple of niggly flaws. First, the backlight level isn't completely consistent across the whole screen. Our review sample looked slightly lighter on the left side - especially the top left side - than it did on the right. I should stress that, post calibration, this issue is so low-level that it only becomes even a small issue during very dark scenes indeed, and is practically unnoticeable if you've got any amount of ambient light in your room. But it would still be nice not to see it at all.
The 100Hz engine is responsible for my other main concern with the 46XV635D. For while watching 24p Blu-ray feeds, although the 100Hz system certainly reduces judder without generating blurring or lag artefacts, it also causes a curious 'twitch', where the image repeatedly seems to pause or even skip back a frame for a fraction of a second.
To be fair, this glitch is actually imperceptible for much of the time, only coming out when objects were scrolling quite slowly across the screen. Indeed, it's possible some people will never see it at all. But I personally found it sufficiently annoying that I switched my Blu-ray deck to output 1080p/60 instead of 1080p/24 - a move that many AV purists may be unhappy to copy.
One final irritant with the 46XV635D's picture is the way black levels and colour saturations drop off rapidly if you have to watch the image from down the TV's sides. But this is hardly rare in the LCD world.
Sonically the 46XV635D is pretty respectable by skinny TV standards, sounding reasonably rich and detailed at the treble end of the spectrum, solid if not exactly beefy at the bass end, and reasonably open in the mid-range, even if you drive it quite loud.
The 46XV635D handsomely overcomes my doubts as to whether it could bring enough extra to the table to justify its cost over Toshiba's cheaper RV635 models. And in doing so, it ends up looking like a real bargain itself considering how much it has to offer.
The backlight inconsistency and 100Hz twitch with 24p Blu-ray playback may put off movie lovers wanting a screen for watching loads of HD movies on, but anyone looking for a more straightforward all-rounder will find much to love - especially given its impressive standard definition talents.
