Samsung LN40C630

Motion Performance

Motion Smoothness (7.25)

The Samsung LN40C630’s motion performance isn’t great, but its 120Hz features definitely help. There are two settings available in the Custom mode: blur reduction and judder reduction. Blur reduction is generally what you’ll want to fool around with if you notice blurring (judder reduction makes the image look like it’s running at a higher framerate). Once you’ve bumped the blur reduction up a bit, you should only see some minor blurring. We noticed the blur was a bit more severe with 1080i content, as compared to 1080p, but neither were glaring issues.

Motion Artifacting (8.50)

The LN40C630 didn’t have many artifacting issues. There was some slight false coloration in fine patterns, which gave said patterns a greenish hue. Moving images also were also subject to a stair-stepping effect, where the top-most parts started moving before the lower ones. Overall, though, nothing significant. More on how we test motion performance.

3:2 Pulldown & 24fps (7.50)

For 3:2 content, turn Film Mode to Auto 1. Once this is on, you won’t see much artifacting at all. Some patterns did flash a bit, but it wasn’t With this setting on, we saw only minimal artifacting on our test pattern. Some fine patterns flashed randomly, but infrequently.

The TV also supports 24p mode just fine, should you have applicable media. More on how we test 3:2 pulldown and 24fps.

Resolution Scaling (8.15)

Overall, the LN40C630 did well with non-native resolutions. It still had some issues with 720p and 1080i, but none of them were particularly debilitating. More on how we test resolution scaling.

480p

The TV barely had any issues with 480p playback. There was some very minor moire interference that created a slight plaid effect on top of whatever pattern the TV is supposed to be showing.

720p

The LN40C630 had some issues with 720p content. The plaid interference was back, and was more intense (though less consistently so) compared to what we saw with 480p content.

1080i

The moire interference reached an unfortunate denouement with 1080i content: the plaid effect created boxes in fine patterns. Though this was definitely noticeable, it was the only issue we saw.
