Viewing Effects Summary



Editorial Note: This is a review of the Toshiba 46SV670U. Test results are for this model, but should indicate the general performance of other sizes in the Regza SV670U series. The Regza SV670U series includes the following models: 55SV670U.  Read here for more details on series differences.

• Bad viewing angle, common in LCD TVs
• Highly reflective screen
• Lots of video processing options
• Testing done using DisplayMate Software

Viewing Angle (3.3)

The viewing angle on the Toshiba 46SV670U is merely adequate, and standard for LCD TVs. At best, we found a viewing angle of 24.74-degrees. Not great.

Reflectance (4.0)

Sadly, the screen surface on the Toshiba is highly reflective. It doesn't seem to help that the acrylic plastic coating ('Infinity Flush Front') seems to be increasing the annoyance levels by causing a mirroring effect. When we shined a light at the TV, we saw two lights. You can tell that Toshiba tried to reduce reflection by scattering the light, which results in a odd, star-shaped pattern. It wold be almost beautiful, were it not ruining my view of the football game.

Video Processing (3.0)

The Toshiba 46SV670U offers a lot of control over the finer points of your image. There's also the usual assemblage of noise reduction, contrast controls, and the like. Not everything here is great, but Toshiba makes it harder than some to royally screw up your picture.

Setting Claimed Function Our Impression
ColorMaster When activated, allows you to adjust the Hue, Saturation, and Brightness of six different color channels (Red, Green, Blue, Yellow, Magenta, and Cyan) A lot of color control that most people will have no idea how to yield
DynaLight A local dimming system to strengthen blacks in dark areas of the screen Not much of a visible effect
Dynamic Contrast Detects changes in the picture and adjusts contrast automatically. Settings of 1-10. It's a pretty conservative increase in contrast, even when turned up to the max setting
Static Gamma Allows you to adjust the levels of blacks Expands detail in highlights and shadows at one end, crushes them at the other end. It's a sensitive control that can wreak havoc with your picture if you're not careful.
MPEG Noise Reduction Reduces visible interference caused by MPEG compression Smooths over blocky artifacts pretty well, but it can smother very fine details. It's a trade-off. Use it, but not at its highest setting.
Dynamic Noise Reduction Enables you to 'soften' the screen representation of a weak signal to reduce the noise effect. Not much of an effect
Resolution+ 'Allows you to adjust the levels for your desired picture settings and get a sharp picture.' (This should win an award for Most Vaguely Described Feature. Incremental increase in fine detail. When turned up too high, results in too much noise.
ClearScan 240 Reduces image lag to provide a crisper image Not much of an effect. Slight sharpening of details in motion.
Film Stabilization Helps eliminate picture shaking. This crisp motion-type feature can be a terrible thing when done poorly, reducing film to looking like shoddy video. Not as bad as similar features on other manufacturer's TVs. 
Other Models in the SV670U Series
This is a review of the Toshiba 46SV670U. The other sizes of HDTVs in this series should be similar in terms of performance and usability. For details about any differences, click on the image to jump to the Series Comparison page.
