Calibration
Viewing Effects Summary
• The SV471XVT had a poor viewing angle
• There are a number of video processing features, but most of these are not useful.
Viewing Angle (3.4)
However big your TV is, only one person gets to sit right in front of it. Everyone else is stuck viewing it from an angle, whch is why we test how well the image holds up as different angles. The answer for the SV471XVT is not very well; we found that the angle at which the contrast ratio dropped to 50% of the maximum was a relatively small 26 degrees. This is weak compared to the viewing angle of other displays; the Samsung LN46A750 had a viewing angle of 55 degrees, and even the Vizio SV470XVT had a much wider angle of 33 degrees.

Reflectance (7.25)
The SV471XVT has a matte coating on the front of the screen, which does a decent job of breaking up reflections from lights. If you have a light by the side of your couch pointing at the screen, you might still see it, but it will be a soft, diffuse reflection that doesn't distract from the image too much.
Video Processing (2.0)
The SV471XVT includes a number of features that are designed to try and enhance a noisy or otherwise poor signal.
| Setting | Claimed Function | Our Impression |
| Noise Reduction | 'diminishes picture artifacts caused by the digitizing of image motion' | Reduces noise on some particularly grainy image |
| Color Enhancement | works by 'reducing oversaturation of certain colors and improving flesh tones' | Options for Off, Normal, Rich Color, Green/Flesh and Green/Blue. Boosts specified colors. |
| Advanced Adaptive Luma | 'Large areas of brightness in the picture will result in a higher Average Picture Level (APL). This feature will lower the APL to counteract this effect' | Options for Off, Low, Medium, Strong and Extend. Pushes shadow detail into black on all settings, especially the Extend option. |
| Backlight Control | 'DCR (Dynamic contrast ratio) improves the black level performance and increases contrast ratio' | Options for Off, DCR or OCP (Optimum Power Control). Dims the backlight on very dark scenes (such as credits) |
The only one of these that might be any use is the noise reduction; this did a decent job of getting rid of some noise on a noisy TV channel. The others aren't worth bothering with.

Samsung UN32D5500 LED LCD HDTV Review
The D5500 has a rather high MSRP of $699, considering it’s only a 32-inch TV. There are some “premiums upgrades,” a term we use with some dubiousness, knowing that these features can be far less valuable than they appear. Nevertheless, at its core this is a good television. If you can find it a significantly reduced price it would make a great addition to a home theater. Read More...
