Toshiba’s SV670U series comes with an overactive backlight and able to deliver some really good blacks, along with accurate color and solid video processing.
The dual color design extends to the big remote control. There are few buttons on the remote control, but suffice to function well. However, it is not illuminated, and small handed people may have trouble reaching the important picture mode and size keys at the bottom of the remote. This remote control is capable of controlling three other pieces of devices.
Setting up the Toshiba 55SV670U
Overall, setting up the system can be easy if not for a wordy 83-page owner’s manual. The step-by-step guide is mostly driven by words, as opposed to illustrations to most other manuals by manufacturers of similar product. A little too technical, a little too confusing, the average user will do better just matching the cables based on logic with any indications available at the I/O panel itself. However, we must give some credit to Toshiba for being so detailed in preparing the manual.
There is no Internet connectivity on this system, even though the mass market has driven up demands for such a feature, and other manufacturers do as much as possible to include this feature into their design.
In theory, the SV670U have a 240Hz refresh rate, which means that by right the TV takes each frame to a standard 60Hz source and repeats it four times. However, Toshiba is not doing that with this ClearScan 240 with Backlighting Scanning technology, instead it only repeats each frame twice, using a scanning backlight system to double those frames to four.
There is a dejudder processing feature with smooth setting. Toshiba allows users to get the anti-blurring effects of 240Hz without having to engage the dejudder. There is a lot of talk about the Resolution+ processing by Toshiba’s marketing propaganda, which is actually applied to standard definition sources.
While the system shows pretty good picture quality, users may also experience more blooming effects, which means the tendency of bright objects spilling over onto darker backgrounds, creating a halo effect. This blooming is evident even in the tv’s own menu system, and worsened considerably for audience seated off-angel from the sweet spot directly in front of the screen.
Sometimes the backlights may not dim enough, and that interrupted the darkness unnaturally. Users may see something like very faint brighter clouding flashed briefly in the shadows. Also, depending on the overall brightness of the scene, the darkness may not remain at a constant level.
However, shadow detail is excellent. There is no bluish or greenish tinge that may be seen on other brands. Color accuracy deserves praise, and skin tones look natural and warm. It may be just a little less saturated in many brighter scenes, but they were still rich. The only downside is that the Toshiba is less accurate on primary color of green and secondary color of cyan, even if it is negligible. Also, this system has the worst off-angle performance compared to its peers from other companies.
There is nothing worth celebrating over the 240Hz refreshing rate, as there is not much difference with a 120Hz. There is a Film Stabilization setting with three choices, namely Off, Standard and Smooth. The difference between Off and Standard is hard to discern. The Standard setting does not include a dejudder effect, so users may appreciate it on a 24p sources for a more natural feel.
The dejudder only exists in the Smooth settings option. This makes a film look more like video, but Toshiba maintained some minor judder but fewer artefacts, which is fantastic.
One annoying thing is the glossy screen that has a tendency to reflect ambient light sources. Toshiba did not use a matte surface for this and the only upset is that it maintained black level performance under bright lights better than its peers with matte screen.
Toshiba flaunt about its Resolution+ processing, but failed to impress with it. It did resolve every detail of the DVD format, and tuning up the level seems to add more sharpness to the image, yet at the same time introduced edge enhancements. It also failed to remove many jaggies from rotating diagonal lines even with the Resolution+. Switching on the Toshiba’s digital noise reduction works well, but the auto function did not have much effects.
Meanwhile, Toshiba does well with the HDMI connectivity. The TV is able to reproduce every line of a 1920 x 1080 source with no edge enhancement or overscan. However, the VGA reproduction could have done better.
However, blooming is more evident on this Toshiba tv as compared to other LED-based LCD TVs out there. The backlight is not stable and easily fluctuates, and the off-angle performance is not going to please the users. The glossy screen reflects ambient light, and there is no distinct benefits seen from its 240Hz refreshing rate.
The review above applies to the SV670U series, 55SV670U for 55” and 46SV670U for 46”.
