Optoma HD8000 1080P Single Chip DLP Front Projector added to the list



The Optoma HD8000 1080P DLP front projector will refresh 1080P/24 material at 48HZ.

Quote
ďThe manual mentions a 48Hz control to display 1080p/24fps inputs at a 48Hz refresh rate, but that control has been omitted. Instead, the projector automatically recognizes when it receives a 24Hz input and frame doubles it to 48Hz with no user action required.Ē

"But fret not, the Mitsubishi Diamond 833 Series offers 120Hz. 120Hz image processing shows 120 frames per second, allowing these TVs to reproduce unconverted, evenly extrapolated 24 fps movie, 30 fps television, and 60 fps special effects programming, without the stutter and other clutter of 3:2 pulldown."
Perhaps the UK models of Mitsubishi displays correctly refresh 1080P/24 material. This list is made up of US models only since I have not researched TVís designed for the entire world. Here is a link that shows that Mitsubishi LCDís are using a 3:2 pulldown technique when a 1080P/24 signal is inputed.

Now when a new 120HZ rear projector Mitsubishi is reviewed I will be watching to see if the US models bypass the 3:2 pulldown process. If they do I will add them to the list.

There is only one WD-73833 and it bypasses the 3:2 process, according to what I have read.

List Updated with correct refresh rates for the Sony VPL-VW60 (96HZ) and VPL-VW200 (120HZ)

I subscribe to just about every Video and Audio magazine that I am aware of like Widescreen Review, Home Theater, Perfect Vision, and various other print and electronic magazines. Once and a while people that publish these magazines make mistakes. Anymore itís getting so bad that one needs to have more then one source of information to see which review or news article contains the correct information.

For example here is a link to why the Sony front projectors were labeled at 48HZ
http://forum.hd-dvd.com/showpost.php?p=6722&postcount=46

The list now has been corrected and the Sony VPL-VW60 is labeled as 96HZ and the VPL-VW200 is 120HZ. The 120HZ for the VPL-VW200 comes from Sonyís original press release.

Quote
ďLike the VPL-VW50, the VW60 changes its refresh rate to 96Hz and employs a "4:4 pulldown" (each frame is repeated four times) when you give it a 1080p/24 signal. I love this feature. This removes the odd judder inherent in all 24-frame-per-second content when displayed at 60Hz (thanks to 3:2 pulldown). The result is a smoother image, but without the overly smooth, artificial look that can occur when a display interpolates frames (which some 120Hz displays are now doing).Ē

Anybody know how the new Samsung TVs (XX69, XX71 and kinda the XX81) process the 24p frame rate? I'm really curious about this as I'm eyeing them for my next set. Thanks.

I am waiting for a professional review on the Samsungs. The rumor I have heard is that the Samsungs currently only interpolate frames instead of using the multiplies of the original frame process. There is a rumor that Samsung is working on a firmware update so their 120HZ sets will do a true 5:5 pulldown. Again these are only rumors and it might be incorrect information. A professional review might not be written on the Samsungs by someone until December or later.

Thanks. I'll be looking forward to those reviews, and thanks for the list. It's really helpful.

I think that this list is great... but I would honestly prefer a list that was only 120 hz. And since it's VERY easy to find those on the list, I'm not complaining.

The reason that I would only want a 120 Hz display, is because I want ALL my video in it's native refresh rate... not just my HD content. Since TV signals are still broadcast at 30 or 60 Hz, I want a display that can equally display those refresh rates.

I don't want to get rid of judder in my HD media, only to introduce it in my TV signal. Maybe the telicline process doesn't have the same problems in reverse... but I don't see why that would be.

I agree some 120HZ displays are great since some 120HZ displays will accept both a 60HZ and 24HZ signal and display it at multiplies of the original frame rate until 120HZ is reached.
Who knows several years from now someone might make a 240HZ display that both 60 and 24 goes evenly into to try and eliminate judder and make the image look smooth. Then one would have 10:10 pulldown for 1080P/24 material with 60HZ material frame doubled 4X.
