Sharp XV-Z20000 to support 1080/24p! - Page 6

post #151 of 270
I'm just guessing here but I assume if you could select 48Hz that would get the job done. You could also try powerstrip to get 24 or 48. I built a new HTPC for 1080p recently but I'm waiting for something better than powerdvd to come along.

Hello,

I upgraded my 21000 today thanks to Steve and checked that the firmware loaded is 1.1.5 indeed.
But my HTPC still doen't detect the ability to display at 24 fps and the lower limit selectable through the nVidia control panel is 25 Hz.
I tried Powerstrip but it shows the same lower limit.
Have anyone tried to get 24 Hz from an HTPC?

Thanks

I just got my projector (Z20000) in December, and it's at the previous firmware version. Could someone please send me the firmware for the full 24fps support?

e-mail: thefans@bellsouth.net

Thanks!

Michael

Can someone confirm 48hz with 24p input after firmware 1.1.5 update ?

Looking for this answer as well!!!

WOW... Straight up no one wants to answer this.

Well, thanks to those who sent me the firmware file. I was able to successfully update my projector to support 24 fps. Previously, I was getting weird erratic 'flashes' and/or changes in brightness on 24 fps material, and now everything is very smooth. I had originally thought I was having a bulb problem, but everything looked fine on regular DVDs. Only the Blu-Rays were giving me problems. But, problem solved!

For anyone who hasn't been able to dig through all the posts, let me summarize my experience simply:

- You definitely need a 9-pin NULL MODEM cable (female-to-female). A regular serial cable will not work. A Null Modem cable is also sometimes sold as RS-232C (as opposed to regular RS-232).

- My laptop had no serial port, and I was not about to lug my projector to my desktop machine or vice versa. So, I successfully used one of those USB-Serial adapters. I was worried about it at first, because of the occasional story/review regarding incompatibility or burning out a component. However, the one I got worked great (with my Lenovo Thinkpad T42). The adapter I ended up buying was made by ACP, and I got it for about $20 on Amazon.

Finally, I have no idea whether it is now displaying at 24 Hz or 48 Hz or what. How actually is someone supposed to measure that to 'confirm'? All I can say is that notice a definite improvement, in that the strange modulation of brightness has disappeared.

SOWK and Acta7, if you know how I can actually measure/confirm the frequency output, I am all ears. Is there some menu option I don't know about? Keep in mind that I am not an HTPC guy. My Blu-Ray source is a PS3.

Having read this thread from beginning to end I am still not sure whether the v1.15 update (a) simply enables the PJ to accept 24p without white flashes, or (b) enables the PJ to output 24p or multiples thereof.

Since I have not experienced white flashes or noticeable judder, so far, I think I will leave well alone and just keep on enjoying its fantastic images.

There are only a couple of sure fire ways I know of. Both require test patterns.

1. Somebody (trbarry possibly) posted a judder test pattern in the HTPC forum you can use to test 24hz, but you have to set up your computer to output 24hz to your projector, which can be a pain.

2. Use a signal generator or scaler to send it. Maybe some forum member owns one near you. I think most of the high end scalers have such a pattern be they Lumagen, Crystalio, DVDO, etc.

Anyone ever find out definitively if 1080p/24 is truly displayed at 48Hz with the XV-Z20000?
post #162 of 270
Is there anyone who could pass me the link for the firmware, or the firmware itself ?

thanks,
Diego

I was lucky that my sharp 20000 already had the update installed when I purchased it.

If you PM your email address I can send it to you. There is no link on this and the file is around 3.5mb.

Count me as a skeptic that this update actually enables the 20K to run at some multiple of 24 (48?) when fed a 24p input. I think it just fixes the playback bugs observed without the firmware update. I say this for very unscientific reasons:

1) I detect no differences in comparing film based segments when running 24p or 60p from my Anthem D2. Pans (slow or fast), moving images, etc. all appear to be the same... of course this is not a direct A/B comparison as it takes a while for the hdmi handshake to finish when switching output formats on the D2. Perhaps the negative effects of "judder" are overrated.

2) Wouldn't the colorwheel have to change speed? Should this not be subtly detectable when switching input from 60p to 24p and vice-versa (audibly I mean... I certainly hear my colorwheel spin up and down when the projector is turned on/off... it is also subtly detectable when running if I put my ear close enough)? I can detect no changes sonically (projector is the only noise producer in the room when system is muted)... perhaps the fan noise overwhelms this speed change.

No big deal... plays fine either way I just haven't been able to detect a single advantage feeding 24p vs. 60p for film based materials.

It could be that your Anthem D2 does such a fine job of video processing in the first instance!

My HDMI feeds pass through the AXC-A1XVA (5805ci) and the differences are subtle. I have also found that there is a variation of effect between different discs.

Does the menu of your PJ confirm that it is actually receiving 24hz while the disc is playing? The Sharp requires players to be in "forced" 24p output mode because the upgrade does not change the the 60hz only capability message it sends to connected equipment. Officially, Sharp have advised their technicians to do the upgrade when customers notice a certain "flash' with 24p material.

One change that anyone should be able to notice is the the scrolling credits at the end of a movie. 24p should be smooth without judder, 60hz there will be a slight judder as the credits scroll. I have noticed that the film material presentation is smoother overall particularly when the camera is panning. I am particularly sensitive to this for some reason and previously found some panning shots very difficult to watch.I am also accustomed to PAL DVD material (50 hz) which does not require 3:2 pulldown and has smooth scrolls and pans.

Like you, I have also suspected that some of the improvements of the firmware upgrade were brought about by tweaks other than for 24p, but that has not been confirmed by Sharp. For example where I would previously notice some video noise on certain discs, this has disappeared. I also feel that the picture is a bit sharper overall, but this is a very subjective observation.

I have now set my blu-ray players to forced 24p output all the time and I only wish I could do the same for the Onkyo HD-805 HD-DVD player!

Yes... forgot to mention that I have confirmed that the Sharp is receiving 24p (via the "Fine Sync" -> "Signal Info" menu) when I use the D2 output config that is 24p. Again, no big deal to me... plays fine either way... perhaps the benefits are subtle enough that I would only notice if I could see them side by side.

I just put out the DT-5000 out of the box and took a quick measure:

Mode: Cinema 1
Temp: 6500K




Wow...

hi ruva,

Coincidentally my DT-5000 was professionally calibrated yesterday and the calibrator was most excited about the "out of the box" color accuracy. He showed me some similar graphs. He went on and said that he would generally look for these kind of results from projectors costing around $50k - He was stunned when I told him about the DT-5000 deal!
post #170 of 270
I'm confused: what is a DT-5000?
This thread os for Sharp XV-Z21000 .. or not?

DT-5000 XV-Z20000 and XV-Z21000 are identical projectors. DT-5000 is the south american model but I bought mine from a dealer in the USA who had obtained a good priced shipment
post #172 of 270
tassop,
that's the truth: I think we got a very good deal on this machine: it is top-notch, first class optic, and almost pre-calibrated !

Locutus,
as you can read on our italian forum, DT-5000 is the south-american version of the 21000, which is the EY version of the 20000....

ciao,
ruva

That's just the gray scale performance. Yes, if you set it to 6500K in the user menu the grayscale is remarkably accurate without any further calibration. However, the primary and secondary colors are quite inaccurate out of the box. The Sharp is one of the few displays that includes a Color Management System (CMS) that allows the calibrator to fix this. I hope that yours did.

If the DVI detective has acquired the EDID of a 1080/24p compatible display, then your setup should work to ensure the BD30 outputs in 24P. I am assuming that your firmware on the PJ enables 24p.
post #176 of 270
Thanks for the advice. yes i have the latest firmware from the lion. will it work if i use the pioneer plasma with 24p to program the dvi detective and use it on sharp? and where should i connect the dvi detective hdmi output of bd30? or hdmi output of onkyo 705?

It should work- you will need to connect the DVI detective to the output of the Panasonic BD30 at all times.

One more thing, this is the DVI detective Plus?
post #179 of 270
yes it's plus and cost $129 that's why need to know if it will work before i buy. one more thing if i use the hdmi output of bd30 i'll lose true hd and dts ma and have to use optical cable for audio. if that is the case then i'll have to sacrifies hidef audio for 24p. is there no other way to have 24p as well as hd audio at the same time?

Good question. I don't know if hdmi-dvi-hdmi conversion will preserve the audio. You can post that question on the Gefen forum or to Gefen support. In the meantime I will get hold of the DVI detective and experiment with it.
