The 100Hz system, meanwhile, definitely reduces the slight resolution loss with motion experienced on Toshiba's current non-100Hz sets. The 37XV635DB doesn't go as far as some rival TVs in this respect -- there's still some judder, and blur isn't completely removed. But, crucially, by adopting a fairly gentle 100Hz approach, the 37XV635DB's pictures are free from the 100Hz processing side effects that you could otherwise see.
Colours look well-saturated and enjoy plenty of blend subtlety too. Although there's more greyness during dark scenes than you get with the best LCD TVs these days, for its price, the 37XV635DB's black-level reproduction is actually pretty accomplished. High-definition pictures look clean and stable, too.
Despite being rather muffled at times, the 37XV635DB's audio sounds more accomplished than the efforts of Toshiba's cheaper TVs. This, we suspect, is down to the set's Dolby Volume and Audyssey EQ processing. The former equalises audio so that you don't get sudden volume jumps between sources or when adverts come on, while the third-party Audyssey EQ continually analyses the audio signal to ensure the TV always sounds as good as it can.
As you'd expect at this price, the 37XV635DB isn't perfect. For instance, when calibrated to deliver the most realistic colours and best black levels, the picture looks slightly starved of brightness compared to the pictures of many rival sets. Also, slightly suspect colour tones occasionally creep in during dark scenes. Finally, even with the 100Hz processing engaged, HD pictures don't look as pin-sharp and detailed as we've seen them look on a few other LCD TVs. We suspect, however, that many people will find the 37XV635DB's excellent sharpness with standard-definition material ample compensation for the latter point.
Conclusion
Although we're not entirely convinced that the 100Hz engine brings enough to the party to justify the Regza 37XV635DB's price hike over its cheaper siblings, this set is nonetheless a typically solid performer from Toshiba, especially if the majority of your TV diet is standard- rather than high-definition.
