Viewing Effects
Motion Summary
• Significant motion blurring
• Obvious artifacts in moving objects
• Good handling of 3:2 pulldown conversion
• Testing done with DisplayMate software
Motion Smoothness (5.25)
One of the Toshiba Regza 40XV645U's signatue features is 120Hz refresh rate, which theoretically should help with motion performance. Unfortunately we didn't see a ton of evidence for this when looking at moving objects on the display. We did like that moving faces held together pretty well, albeit with an obvious cartoonish cast, but we saw massive amounts of motion blur with moving blocks of color, especially when viewing in 1080i. We've seen significantly better motion smoothness from other HDTVs that sport 120Hz refresh rate, although we should also mention that if you turn this feature off things get really ugly.
Motion Artifacting (4.75)
Artifacts are things that appear on the display that should not be there. With the Toshiba Regza 40XV645U we detected quite a few artifacts related to moving objects. There was a very obvious judder in certain moving scenes, and we also saw the same rolling shutter effect we've seen on other HDTVs, although the 40XV645U was actually a bit better than average in this respect. What concerned us more is that we saw a flat out inversion of colors in some moving objects, which should never happen.
3:2 Pulldown & 24fps (8.5)
3:2 pulldown is the process by which an HDTV converts broadcast content that is received at 60 frames per second into 24 frames per second. This is primarily done for films that are supposed to be viewed at the lower frame rate to get that film-like look. The Toshiba Regza 40XV645U did a good job with this conversion, with barely noticeable glitches in our test pattern. You do need to turn on the Film Stabilization feature in the advacned picture menu in order for this conversion to happen appropriately, but there's really no reason not to leave this feature on. There are two options here, Standard and Smooth, in addition to Off. We didn't see a significant difference between the two so select the one that looks best to you. The 40XV645U also supports content that comes in natively at 24 frames per second, for example films played from a DVD or Blu-ray player.

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...
