Official JVC RS20 / HD750 Calibration and CMS thread (NEW FIRMWARE V1.1) - Page 2

post #31 of 1634
I don`t know who at JVC you are getting your info from. there are many many US model members posting here. I doubt there are any differences between the UK model and the US model other than the power cord used. The CMS in all US models was not properly designed, pure and simple. JVC has now fixed the problems. Down load the new CMS software to your projector. Turn it on and run it for about 80 hours before you pay for a calibration. If your calibrator is any good, and probably more are less good than they should be, i.e., get a proven professional with lots of experience, not just someone who passed some ISF test, you will have accurate colors. You will not get the benifits possible from your machine without the new software.

4. Hold down the Standby/On button on the projector and plug the mains lead
back in while still holding the button down. The three LEDs on the projector
should all light to show that the projector is in Download Mode.


Help me! Hold down Standby/On button,But three LEDs can't light , us model. what's wrong?
Thanks!

Is the USB cable plugged in and connected to the running PC/laptop?
post #34 of 1634
Glad to hear this thing has officially been released. I'll give it a try soon.

Thanks! USB cable,PC and ILAFPJ driver ...All of Correct.
still holding Standby/On button is POWER ON, not in Download mode.

Pengiun, I'm not sure what the problem is. Presumably the projector just powered on as normal? Have you tried again since?

Thanks JeffY
my rs20 remove the mains lead, waitting for 20 mins, Standby LED always RED.

UPDATE PROJECTOR FIRMWARE
With the projector in Standby mode, remove the mains lead from the projector
and wait until the Standby LED goes out.
post #39 of 1634
The standby light stays on even with no power cable plugged in? That is odd, eventually it must go out. On my unit it took about 5 seconds for the light to go out.
post #40 of 1634
ok! if remove power cable. standby light 5 sec off.
but remove main lead = remove power cable ?
post #41 of 1634
the mains lead is the power cable.

Could we try as much as possible to keep this thread for calibration reports/questions, and the firmware upgrade thread for, well, the firmware upgrade questions? Just trying to avoid having ten pages about the upgrading process and keep some clarity for the calibration process itself... Also we know that GaryB is monitoring that thread, so you'll probably get faster support from him there as well (not that JeffY is not doing a fantastic job both here and there of course!).

Manni, Jeffy:

Many thanks for your feedback.
Is it clear that the new CMS firmware is modular to the extent that loading the new CMS firmware affects only the CMS settings and behavior?

In other words is it clear that the new CMS firmware has no effect on previous/existing Gamma and Gray Scale Calibration settings? I assume THX behavior has not been impacted..is that correct?

Thanks
KT
post #46 of 1634
ALL settings get reset, including things like the ceiling mount setting. THX looks the same to me but I have not measured it.
post #47 of 1634
I had Jason calibrate my RS20 when I got it from him in Jan. Would there be much of an imporvement if I had Jason update the firmware and recalibrate the projector? I am quite pleased with the image already.
post #48 of 1634
Agreed, the new firmware seems to completly re-write everything to factory default settings and I can't see any change to the image compared from memory with the original firmware THX mode .
post #49 of 1634
The THX mode is not effected by the firmware.
post #50 of 1634
Hi,

Thanks to everyone that have made the effort to get this update done. One question? I wonder if after the firmware update is done if I put back my calibration numbers that I have will I get back to the same picture?
post #51 of 1634
Probably not. Because of the old control interactions and non linearity.

You may if you're talking about color temp/greyscale, you probably won't re gamut, and frankly I can't think of any reason why anyone would want to do that, given the much better results offered by the new CMS.

Yes, as JeffY said, all the parameters reset to factory defaults when installing the new software, so beware if there are any settings you'd like to keep (especially not calibration related ones if you haven't setup your PJ yourself).
post #53 of 1634
Thanks, Mark!

I had my projector calibrated by Michael TLV. I may do the firmware update and get him to come back for a tune up.
post #54 of 1634
Manni, thanks for the reply!

I was just wondering because the calibrated picture that I have now is the best of all the settings. I don't have the equipment to do the calibration by myself. Having it professionally done was the best money I have spent in relation to amount spent on the hardware.
post #55 of 1634
I think that if you put all the settings back in (including CMS settings) you would get a similarish picture, it might even be an improvement on what you had. Ideally you need to re-calibrate, but if you need to get someone in, the previous settings would probably be fine for a while. Try it, if it looks crap just stick it in THX mode.
post #56 of 1634
Jeff,
I guess the only way we would know for sure, is that if one of you guys that have done this puts back your numbers and checks the results.

My advice is, if you're happy with the picture, keep it as it is until you need to recalibrate it (new lamp?). I wouldn't erase a professionally done calibration for a DIY one if you're not experienced. I wouldn't either upgrade the firmware if you don't plan to do your own calibration (or to get one done right away), as it won't bring you anything... Just my .2 cents...
post #58 of 1634
Manni,
The picture is very good, but even as good as it is the calibration fell short for many of the reasons discussed here. Just knowing that we can get it dialed in a little closer has me weighing my options. Thanks for your input!!!

Hi Manni - thanks for all the reports/updates. I was rather surprised to read the quote above based on Phil's review a couple weeks back. It seemed from Phil's review he put the CMS through some extensive testing, and I don't recall any such findings from him.

It will be interesting to hear your results when calibrating at 75%. I suspect the opposite may happen (on target at 75%, then somewhat undersaturated at 100%).

Unfortunately I am super busy with work and don't know when I'll get a chance to dig in, because I know it'll be an extensive exercise once I do.

It'is great to hear that the clipping issues are history and I look forward to reading more about your and others findings with the 75% vs 100% linearity tracking.

Also - I know you are aware of this and this was a very preliminary calibration just to get a feel for the new firmware, but I'd recommend dialing in your grayscale much flatter sooner than later. It wouldn't affect linearity but will affect the color tracking otherwise.

As I understand it, you are reporting that all settings are lost.
It is reasonable that all settings will be lost when installing the new firmware, but I did not really ask the right question in my last post. This is what I meant to ask:
Based on your visual observations after installation of the new firmware and after resetting any original settings lost during the installation - are the original Calibrated Color Temp and Gamma performances you saw restored? This should be the case if the CMS firmware is a separate module from that for the Gamma firmware module and the Color Temperature Firmware module.

Since the Color Temperature and Gamma functions are related only to the Luminance behavior of the projector, I would expect theses functions would not be affected at all by changes to the Color Management System firmware.

The answer to these questions will determine if ALL previously calibrated work on the projectors is lost --or if any Gamma and Color Temperature Calibrations that have previously been done will still be effective once the original user settings are put back in.

Your findings and thoughts on this will be appreciated.

KT
