Does TH42PH10UKA support 720p 24?

Hey everyone

I'm considering getting this Panasonic Flatscreen monitor for use with my edit system. Most of the footage we'll be editing will be 720/24p, and we also shoot DV 24p footage.

Does this monitor support 24p?

As far as I know, all pro plasmas support 24p. 24p looks good on our 50 and 42" panny plasmas here at the shop.

Nick,
I think the manual should be available online in the support and documents area. Look in the specs section for scanning formats. My TH37PH9UK (a year old or so) does NOT support 24P in 480 or 720--only 1080.

To view 480 24p DV on it, I have to set my Kona output to NTSC 29.97. It works, but it does not look great. Basically, the Kona has to add pulldown to make it 60i and then the monitor deinterlaces it again for display. I have not tried to view 720 24p, but the specs say it only accepts 720 60p, so the Kona will have to convert to that. I've only used it for 720 60p myself.

Download that manual and see if you can get knowledgeable help from a Panasonic rep. Maybe the new models do more 24p modes than mine does.
-Tom

DOH-

there is NO way to view 24p SD content on anything but a computer display- same with 720p24 - the SMPTE spec for both formats requires that when playing as video that SD adhere to the 29.97 fps and for HD it is 720p24/ 60

Other than on a computer screen what you are asking does not exist, neither of those formats can be played as 23.976 content via a kona card.

...to add to Gary's comments, of course dv ntsc looks like shite on an hd plasma. There's no way around that unless you run it through a hardware upscalar first. A 720p60 stream (24p with pulldown) will look much much better.

Nick, how are you planning to connect to this monitor? Do you have a capture card?

10bit SD looks terrible on the display as well. This is an HD display, not SD. Any SD will not look good on these displays whether it's uncompressed SD from your edit system or from your cable or satellite input.

This is why we still have standard def monitors in our suite. We never use the plasmas to review standard def material.

It won't accept 720p/23.98

Set Kona to 720/59.94 even in your 24fps timeline. Panny Pro looks great. It just dupes frames, and you'd be pressed to tell

It's an HD display??? Like I said, it looks like cratp with the SD.
There are monitors that claim to display 720 23.976p however. Look at the Ikegami (V-R171P-AFHD). The Kona 3 also lists 23.98p in its spec (as an intermediate format only). I s'pose there are people using that, no?

When you edit @ 23.98 it is for the most part ALWAYS displayed @ 720p59.94 (which in this case will be 720p24 with 3:2 pulldown to bring it to 720p59.94). The Kona uses 720p23.98 as an intermediate format to cross-convert from 720p23.98 to 1080psf23.98 and vice versa. When you want to view 720p23.98 on a monitor you will see 720p59.94.

Yep and we agree. You should not be doing any critical viewing of SD material with any HD plasma display.

Thanks guys.

I think my answer is: Yes the Panasonic monitor will work with your 720 / 24p footage, you just have to set the Kona settings AND the sequence settings to 60 for viewing on the monitor.

And it looks totally fine.

Right?

(I am wondering about slow motion or native 24p footage, or any other stuff that is over cranked or undercranked)

Just want to be sure. I love the Panasonic and want it over any of the others.



And yes, I have a Kona.

we just picked up a TH-50PF10UK 50" last week and it is SWEET (fed by Kona3) it also now comes with the HDMI and component cards already installed. SD is not too bad on it either. one thing about the PH series is they are not full 1920 x 1080 like the PFs.

FWIW, this has not caused any issues here when working with 1080i material. The plasmas still display the material perfectly.

NO TV monitor can display 720p24....

it is not a legal video signal.

In addition to being lower rez, the the PH10uk displays 24psf at 60hz. The PF10uk displays 24psf properly at 48hz refresh.

Set the K3 to 720/23.98 and the secondary to 1080/23.98 and feed that to the 10uk for proper editing.

Chris, that is good info about the refresh rate. Can you (or others watching the thread) answer a question for me?

My manual for the TH37PH9UK shows a "vertical frequency" of 47.92 for an input signal of 1080 24sf. Does this mean that it "displays 24psf properly at 48hz refresh" as you mentioned in your post?

I'm also curious as to why it lists the "vertical frequency" for 480 60i as 59.94 but for 720 60p and 1080 60i it's 60. Why isn't it 59.94 across the board?

Its been awhile, but from what I recall the PH9 series only displayed 24psf at 48 when using the RGB (analog) inputs, I remember not being able to get it to work properly using the HDSDI or DVI input cards, always added pulldown to display at 59.94. They fixed this on the 10 series.

as for 60hz at HD resolutions, not sure why they list that, probably Japanese to English typo. I know it is 59.94, that is what I program the display drivers for when using them in multichannel installations where sync is critical - and that is what their EDID lists for DVI.
