Pioneer's 2007 plasmas have a de-judder mode.

Hi David,

Based on my price range and the reviews I’ve read, including yours, I’m very interested in the Samsung PN50A550 and the Panasonic TH-PZ85U series. However, when I went to see them in the shop, I was very impressed with the video quality of the Sony KDL-XBR4 and the Samsung LN-T4671F. The first two are plasmas and the second two are LCD’s, but I was most impressed with the smoothness of the latter two. You commented on that smoothness in your reviews and made it seem like it’s a feature that can be turned on/off. Anyhow, I was just wondering whether that feature is available in the plasmas I was interested in. You seemed to comment how it can be unnerving at

times and it seems like a feature than can be adjusted. There isn’t much of a mention of it in the Samsung A550 review and I just wanted to know whether that smoothness can be turned off/on in the plasmas. Thanks, Jon

Hi Jon,

That smoothness I mentioned in my reviews is the conclusion of a de-judder video processing mode. Pioneer put a similar mode on its 2007 plasmas, including the PDP-5080HD (pictured), but it’s not as smoothing and it introduces a lot more artifacts compared to the LCDs I’ve tested, so we preferred to leave it turned off. More recent reviews of de-judder-equipped LCDs include the Samsung LN52A650 and LG 47LG60. To reply your original question, I don’t know of any plasma TVs available now aside from Pioneer’s models that have de-judder processing….
