Comments on: The Relationship Between HDTV Refresh Rate and Frame Rate http://www.tech-evangelist.com/2008/10/15/hdtv-refresh-rate-frame-rate/ Technical Articles, Musings and Opinions from Tech-Evangelist Wed, 21 Jul 2010 17:18:00 +0000 hourly 1 http://wordpress.org/?v=abc By: Doogie http://www.tech-evangelist.com/2008/10/15/hdtv-refresh-rate-frame-rate/comment-page-1/#comment-10384 Doogie Tue, 17 Feb 2009 21:45:15 +0000 http://www.tech-evangelist.com/?p=200#comment-10384 Hi Fran You may not notice any judder at all on the Sony. It depends upon how well your Sony model handles the refresh rate, plus the recoding quality of the Blu-ray disk plays a role. I see some judder even on the 120Hz refresh rate TVs with some movies, but I know what to look for. Many people would never notice it at all. There aren't very many 120Hz HDTVs on the market. I think you need an XBR4 series Sony before you get the 120Hz refresh rate. I see the strobing most often with busy scenes with high contrast, such as a camera panning through trees with a bright sky in the background. With some Blu-ray disks, judder is still apparent, even with a 120Hz refresh rate. Keep in mind that not all Blu-ray recording quality is the same. There are a lot of variables that go into a Blu-ray movie. Blu-ray quality and features are still evolving. The new wave of high end HDTVs has a 240Hz refresh rate. I'm not sure if that is necessary.

How much of a problem is the 60Hz rate (judder)?

I just started writing a technology advice column for the novice user (Tech handy dot com). One of my first articles was on HDTVs. I decided to link over to this article for an explanation on refresh rates, as I didn't need to re-invent the wheel. Happy writing. H Gregory Good article.
