Viewing Effects

Decent viewing angle for an LCD. Screen is reflective.

The Samsung LN40C630 is a 1080p HDTV that supports 24p and 3:2 pulldown.

The LN40C630 had a decent viewing angle for an LCD. You’ll only dip below 50% contrast ratio when you get about 33° away from center. A total viewing angle of 66° is nothing to sneeze at, although it pales in comparison to the near-180° most plasmas have.

Viewing Angle Chart

The Samsung LN40C630 had some issues with reflectance. When the screen is dark, external light will create vertical and horizontal streaks as well as minor diagonal streaks. Fortunately, this 8-point star effect is diminished significantly when a brighter image is on the screen. Even on an all white screen, however, the screen is highly reflective. We perform these tests with an array of LEDs, and we were able to clearly see each individual LED in the reflection.

The good news is the streaks aren’t particularly bothersome if the light is shining in at an angle. You might catch a reflection on the bezel, but non-direct light won’t be a gigantic issue. Just make sure there’s no window near the LN40C630 and you’ll be fine.

The LN40C630 has a handful of video processing options. For the most part they worked as advertised, although we keep failing to see any discernible differences in the Edge Enhancement feature, regardless of the TV’s manufacturer.

Setting Claimed Function Our Impression
Digital NR Reduces the noise of the picture to avoid distracting flickering. Reduces a significant amout of noise.
Flesh Tone Adjusts the flesh tone ot be more or less red. Made some fair-complexioned people look slightly more red. This looks more unnatural than you would think.
Edge Enhancement Sharpens the edge detail. No discernible differences.
Dynamic Contrast Automatically controls the contrast level to avoid excessive level differences while maintaining the optimal picture contrast. Dynamically adjusts contrast, as advertised. This can lead to loss of details.

    Samsung UN46D6000

    Everyone wants a Smart TV, but how smart is buying the Samsung UN46D6000 for its $1299 MSRP? With its reasonably good performance in many categories and more internet features than you can shake an e-stick at, that question might be hard to answer if it weren't for this review.
