Poll: Do you turn your HDTV's motion processing on or off?
TruMotion, expletive inducing Auto Motion Plus, MotionFlow, every manufacturer has some slick name for its 120Hz / 240Hz / 480Hz etc. motion processing technology that speeds up the refresh and interpolates frames for an ostensibly smoother video experience, but we know that isn't always the case. It can vary from the implementation to the content viewed, but after the "triple ball effect" and experiencing one too many films that suddenly look like soap operas, finding out how to disable the effect is one of the first things we've learned how to do on many TVs. Of course, everyone has their preference, let us know how you feel and when it's best put to use.%Poll-56018%
HDTV tests pit fantasy land specs against real world performance -- guess what happens
Good luck keeping up with the ever changing specs on the latest HDTVs, but as the numbers get more impressive, are the displays actually improving in any noticeable way? Dr. Raymond Soneira , president of DisplayMate, goes about breaking down many of the more often misused and misleading technical buzzwords in an article on MaximumPC. If you're wondering how manufacturers have advanced contrast ratios from thousands, to millions, to unlimited over the space of just a few years, there's a breakdown of what "dynamic contrast ratio" actually measures and why it's worth ignoring -- unless you watch your TV when it's only displaying one color at a time. When it comes to colors, some of the most scathing words were pointed towards Sharp's Quattron quad-pixel technology, which "can only decrease picture quality and accuracy!" Whether you believe the good Dr., a glistening review or Cmdr. Sulu, the factual heat burned hottest during a test of motion blur compared on LCDs, LED LCDs, plasmas and even a pro CRT. While additional motion processing and upgraded internals on newer HDTVs can help in many other ways, viewers couldn't detect any blur caused by a display even on an old 60Hz set, despite newer and faster 120Hz, 240Hz and 600Hz (plasma) sets claiming their technology helped them eliminate it. You'll need a minute to read through for the full details but it's a good, and unfortunately necessary, reminder to keep your eyes on the display and not just the spec sheet (just make sure you're getting a proper look that represents the way you watch TV at home first).
NuVision bringing 120Hz "FX5" tech to Lucidium LCDs
Falling right in line with just about every other LCD manufacturer, NuVision will be incorporating 120Hz tech into its Lucidium line of LCDs later this year. But we all know that "120 Hz" spec won't stand out on the box art, so the company is calling it FX5, or "Film Times Five." At least this name might help consumers understand all 120 of those Hertz are meant to make an exact five-fold increase of 24 fps film for judder-free viewing. The "more Hertz is better" mentality will probably prevail, but at least we can hope, right? The FX5 designation will be spread across 42-, 47- and 52-inch models, named NVU42FX5, NVU47FX5 and NVU52FX5, respectively. Based on some reviews, though, we're hoping NuVision makes more than just this feature change to the sets, or lowers the prices by the time these appear in Q4.
PS3 firmware v1.90 adds (forced) 1080p24, expands AVCHD support
The PlayStation 3's latest firmware update is out in Japan, adding an option to force 1080p/24 Blu-ray/DVD playback to the console, among other features. Continuing the steady flow of updates for the PS3, v1.90 also adds playback for AVCHD files from Memory Stick or digital camera, upscaling for audio CD output over HDMI or optical output, the ability to change XMB wallpaper, adjust video output settings for PSOne and PS2 game while in game and an "eject disc" option on the XMB. The official PlayStation Blog says the update is "coming soon" to the U.S. so keep that 24fps-compatible HDTV ready for judder-free movie playback.Update: Added in this update is the ability to "force" 24fps output, which should fix compatibility issues with certain displays.

Hitachi's Reel60 processing technology eliminates 'judder'
Expanding a bit on the Reel60 technology first unveiled in a trio of 1080p sets from Hitachi, the company has reportedly developed a system that eliminates the "mismatch between the motion of films seen in a movie theater and the way that same motion appears on television." Dubbed "judders," these jagged edges will reportedly no longer be apparent on select Hitachi sets, as the Reel60 technology perfects the 3:2 pulldown process by "creating interpolated frames based on the original film images." Interestingly, it wasn't mentioned whether Hitachi would be holding on to its newfangled discovery or licensing it out to other manufacturers, but if anyone feels like coughing up the dough to pick up a P50V701, P50X901, or P60X901, be sure to test it out and sound off below.[Via DealerScope]
Hitachi's fall lineup is all 1080
Hitachi has announced a fall lineup of plasma and LCD displays, with the main selling point that all of the sets include 1080 lines of vertical resolution (although two of the plasmas offer a stretched 1280 x 1080). There are ten new HDTVs in all, with a 60-inch plasma and two 55-inch models, three 50-inch plasma displays, and four LCDs in 47- and 42-inch ranges. All models include Hitachi PictureMaster IV or V video processing, and some include a new technique to eliminate judder on 3:2 pulldown called Reel60. Some models also offer Power Swivel to allow the display to turn up to 30 degrees. The models range in price from the 60-inch Director's Series plasma at $7,996 to the 42-inch S-Series LCD at a mere $2,300, and will be released steadily throughout the summer.
