That's great!

Sure appreciate taking this idea to next release. ;)
Hi, these options are now available using the LightSpace CMS 7.1.1.2303 (08 November 2015). :)

So, there is no way to get this to work? What a bummer...I wanted to give the software a try.
There's a "user-generated" dll file that supposedly would make it work with the retail version of i1d3. I did look into it as the Free LightSpace DPS doesn't seem to have any advantages over HCFR

Where can I get it? Still would like to give it a shot. HCFR crashes on me sometimes in the middle of a run. Also, the GDI doesn't measure 0% (although madTPG does work). The icons on top always seem to get re-arranged and don't "snap" tot he top like I'd like. I suppose I should put in log files or something--just haven't the time.

Hi, send me a PM with your email to forward you that file. Thanks.

The latest release of LightSpace CMS includes a fix for the RGB Bars Widget display, so all should be working correct for Manual Calibration again now.

The latest LightSpace CMS version, and the free DPS license can be downloaded here: http://www.lightillusion.com/downloads.html
(Select the 'Free LightSpace DPS' option from the drop-down list, and the reply e-mail will include the DPD license and a link to the software downlaod)

Hi, send me a PM with your email to forward you that file. Thanks.

Hello,

I was pointed to this thread http://www.avsforum.com/forum/139-display-calibration/2155625-free-lightspace-dps-manual-display-calibration.html

Would it be possible to send me this custom DLL which "unlocks" the retail version of i1 Display Pro to use with Lightspace. I will greatly appreciate it, trying to check this Lightspace free version, but have only a retail version of the probe. My email is [email protected]

Thank you very much,
Cristian

Hey Steve,


I think I still have this issue with the RGB bars when trying use BT1886 color space.
When I adjust for the luminance target, despite a relatively low dE (~0.2 to 0.4) the RGB bars are all equal, but noticeably above the line.
As a test, I switched to rec709 and the behavior was as expected - meeting target Y, and balancing RGB, the lines are right on the zero line.
I have a relatively high black point, and as I very rudimentarily understand it, BT1886 is somewhat of a moving target when it comes to overall gamma.
When properly adjusted via HCFR, my average gamma with BT1886 curve is about 2.2.
Do I need to create a custom BT1886 color space with a 2.2 gamma target, or should the lines adjust according to my measured black and white points?
Hope that makes sense.


Another question - Using a direct HDMI connection, is there a way to have the generated patch keep its dimensions.
Every time I reload the program, I have to readjust the patch size to get approximately 10% for my plasma display.


Thanks for the help.

Oh - thanks for the info.
We'll look into the use of BT1886. You have probably found something we have missed...
I'll run some tests and have a chat with the Dev. team!

With BT1886 you do not have any 'gamma' value to set. It is always based on 2.4, and then uses the min/max luma values to adjust the low end of the curve.

With regard to patch size with direct HDMI, have you yet downloaded the new version with the new Network Manager?
If you use that with the Java App 'Calibration Client' TPG you can set the size, position much more accurately.



When the Calibration Client TPG window is double clicked it will go 'full screen', with no border around the window.

This means you can easily set a 10% patch on a black (or any other colour) background.

Yep - you have found an issue we had missed with the BT1889 target for Manual Measure!
We are working on a fix now...

Thanks! At least now I know I wasn't going crazy in my understanding of the program.

Thanks! I'll try this later.
I'd planned to use the 'calibration client' off my HTPC, but I wanted to get more comfortable with the program as-is with the direct HDMI connection. Didn't think about running the client on the local laptop.

Right, we found and hopefully fixed the BT1886 bug.
A new build will be available in a day or so...

Thanks again for the feedback!
(We actually get little feedback as we tend to have very few bugs...)

Using the Calibration Client via 'Localhost' actually makes a lot of sense ;)

Multiplier for HDR Projector "Calibration"

I am trying to use your free software tool to do a manual HDR calibration for my Epson projector. I have Masciola's patterns to do this (and I understand that HDR calibration for projectors is a crap shoot at this stage).

Your guide suggests using 10x as a multiplier for the EOTF curve. I also read on the main Lightspace forum to try other multipliers such as 4 or 6 and see what works best. But given it is quite difficult to set the gamma to align with the EOTF curve, the fewer options I have to test the better.

If I am only reading around 50 nits off the screen, should I be setting the clip point at 500? I've read that 1,000 nits is a good target, but that would require me to set a multiplier of 20.

Any guidance on the best multiplier in this situation?

HDR calibration for a display with a low nits output is a guesstimation...
However, the 'multiplier' function in LightSpace is for 3D LUT generation, and I'm not at all sure how that would equate to a manual calibration (as the free DPS license cannot be used for 3D LUT calibration), as you can't add any roll-off, and that is a key part of HDR, especially on low output displays/projectors?

Hey Steve,


With one of the recent updates, we're allowed to go full screen with the java client app.
The problem is that it seems to only go full screen on the main display, and can't be done on the extended display.
I'm using a laptop, extended to my display for measurement, and trying to use the java client as you suggested above.
I can maximize it to the extended display, but that leaves the info bar up. When I double click it to get it full screen, it moves the patch to the laptop display.


Thanks,
CFC

Thanks for your response. In this post, you stated that it is available for manual calibration as well. And the functionality does appear to be enabled.

http://www.avsforum.com/forum/139-display-calibration/2130474-hdr-calibration-discussion-22.html#post50712953

How does the multiplier work? Does it apply the multiplier across the full luminance range or does it only apply it once the max luminance of the display has been reached? Not considering the roll off with this question.

If you build a new ST2084 colour space, with the multiplier active, you can use that as a target for manual calibration.
All the multiplier does is 'pretend' that the display is 'brighter' than it really is, by the multiplier factor - so every measurement value is affected.
