60hz V10 vs 120hz Others.

[Streaker76]

Just have a question that's one my mind. I just purchased the Panny V10 50" the other week. Enjoying the picture immensely. Is there really a need for a 120hz refresh rate. I'm a little confused on the 60hz, 120hz, 600hz. The V10 is a 60hz. Is it still a better than the others. Enlighten me please.

Thanks

Well the V10 does 48Hz 2:2 and 96Hz 4:4 pulldown for BD doing 1080p 24fps which is what you want because it's a multiple of 24 which gives you perfect playback. The 600Hz is the subfield drive of the V10 and is what helps it achive 1080 lines of motion resolution. The 120Hz in LCD's is for motion blur issues and also 5:5 pulldown for 1080p 24fps. Hope this helps. Your doing really great with the V10 it's a wonderful display.

Due to the differences in display technology between Plasma'a and LCD's, you can’t compare the refresh rates equally because they don’t measure the same thing.

By definition, a TV’s refresh rate is the number of times per second a single video frame is redrawn on the screen. LCD technology can refresh the frames 60 times every second (60Hz), 120 times every second (120Hz), or 240 times every second (240Hz). The faster images are refreshed on-screen, the smoother the video motion will appear. Plasma HDTVs only redraw video 60 times a second, but because plasmas use a different method to display the video frames (by electrifying cells of neon and xenon gas), motion blur is a non-issue.

In the end, LCD's are still more likely to suffer from the effects of motion blur no matter what there refresh rate is because a video frame will stay on-screen slightly longer than it would on a plasma. Plasma use a technology called a sub-field. This is where the "480Hz" or "600Hz" that you may see in advertising or technical specs comes into play. Terefore, a 600Hz plasma produces a 60Hz refresh rate in 10 different sub-fields to improve the set’s ability to smooth motion in video and improve the clarity of still images.

Why did I just feel like Frank the Tank for a moment??

Great help... Answer a lot about the 60 and 120 etc.

Then another quick question,

Seems like the refresh rate should be better. I have a PS3 with the 1080p/24 output setting to "ON" and the TV set to 96hz but didn't notice to much. Now most of the PS3's video settings are set to "Automatic"...should I turn the 24hz output off?

I thought the picture would be much smoother but maybe I'm wrong. Is it the way the movie is being film and they way the director intented.

Thanks again.

Steve,

Definitely leave the PS3's 24Hz function on. This way, it will send the native 24p video to your V10, and your TV will use its 96Hz refresh function to perform even pulldown (4:4) and display the 24p material properly. Confused? LOL...

If you turn off 24Hz output on your PS3, then Blu-ray 24Hz output will be converted to 60Hz output (using an "uneven" 3:2 pulldown scheme to achieve a properly timed video signal). This will intruduce some video "judder" on your TV.

There are few TVs out now which don't handle the 24p frame rate. The best advice is to use the 24p output function on a player if the TV can accept 24p native video.

Thanks again for the info. I'll keep pluggin away learning.

Thanks

Streaker76,

As much as I love my Sony XBR4 LCD, with its 120Hz display, I can tell you for a certainty that your Panasonic V10 plasma produces far superior black levels and motion resolution. Worry not about all the refresh rates you are seeing. The V10 is at the top of its game and offers among the best video quality currently available.

The only advantage of a 120Hz LCD (over any typical 60Hz TV) is that it can do even pulldown of 24 frames-per-second film rates (5:5 as Sonny mentioned, along with 4:4 for 30fps and 2:2 for 60fps). It also allows for "frame interpolation" which can smooth out motion considerably, but it's side-effect is that it makes film look like video (the "soap opera" effect). Many film enthusiasts, myself included, are not fans of this, although some do like it. IMHO, frame interpolation brings down picture resolution a bit, and also adds detrimental video artifacts. I keep the frame interpolation feature turned off on my Sony.

With your plasma, you will always be free of these issues, as the pixel refresh rate of plasma has not deemed it necessary to add any special operations to smooth video or involve additive image processing in any way.

Thanks for the quick reply that too answers a lot. I really don't like the soap opera effect. I'm extremely impressed with the TV thus far. Especially coming from a older rear projection.

Thanks
