Toshiba Regza 46ZV555DB review: Toshiba Regza 46ZV555DB

The Good Good HD picture; simplicity; films look very good.

The Bad Styling isn't as attractive as the picture-frame range; price is too high; Resolution+ isn't that impressive.

The Bottom Line We had high hopes for the Toshiba Regza 46ZV555DB's Resolution+ upscaling technology, but we just weren't that impressed with its performance when dealing with real-world material. The HD quality of this TV is great though, and sound is good enough for most applications -- just avoid the bass-enhancement feature. Overall, we liked the 46ZV555DB but, for the price, we think you'd be far better off with one of Toshiba's slim bezel TVs, such as the Regza 40ZF355D

Let's make one thing clear. The 46-inch, 1080p LCD Regza 46ZV555DB is not, as Toshiba has claimed, "the world's first upscaling TV". All HDTVs upscale everything they show. If they didn't, TV shows from Freeview would appear in a tiny box in the middle of your screen. Of course, Resolution+, the technology that Toshiba includes in this TV to perform the upscaling, is designed to be more capable than other upscalers.

In theory, this TV, available for around £1,000, should offer the sharpest and most impressive Freeview images imaginable, but how does it fair in practice?

As far as aesthetics go, the 46ZV555DB isn't a bad-looking TV. It's a straightforward, glossy black affair, with a 'dissolving colour' effect at the bottom of the bezel. Don't ask us what that's all about -- we really aren't sure.

At the back, you get a rather meagre two HDMI ports. In 2009, we really don't think that's enough. The TV redeems itself slightly by adding a third HDMI port on the side, along with the composite video input. In an ideal world, a TV this size should really have four HDMI inputs -- it's not like these connections cost big money to include.

For older, analogue video sources, there is a pair of Scart inputs too, as well as component video, which is really handy for games consoles. You'll also find a VGA socket, should you want to connect a home-cinema PC or a laptop to the TV.

If you want to improve audio from the TV, there's a subwoofer output, which is useful for increasing the low-level sound effects on movies. There's also an optical digital output, which will enable you to send digital audio to your AV receiver for increased sound quality and volume.

The front of the TV is reasonably clutter-free. You'll find a simple power LED that tells you when the TV is either on or in standby mode. Like all Toshiba TVs now, there is a proper power switch too, lurking around the side of the set. Also present is an illuminated Toshiba logo. The practice of including glowing logos is, sadly, becoming more common and, while we don't think anyone will hate it, we can't think of anyone that would request such a feature either.

We hoped for more HDMI ports on the 46ZV555DB's back

The remote control is the usual Toshiba affair. We have no complaints about it, and it does the job well. The buttons are large enough for all but the most ham-fisted users and there aren't any confusing controls to befuddle the less technically minded.

Resolution+ is one of this TV's most important features. Toshiba has claimed that with this technology DVD can look as good as Blu-ray, and 1080p video can be upscaled to 4k resolutions -- in other words, four times the resolution of 1080p. That's all marketing talk, of course, and must be taken with a pinch or two of salt.

Resolution+ is based on the same technology that runs the PlayStation 3. Part of a joint venture between a number of large electronics firms, the Cell Broadband Engine is designed to process massive amounts of information very quickly. The idea here is that, as TV pictures are so complicated, an upscaler must be incredibly powerful to do a good job.
