That's good to know especially since I spent half a night for my calibrations
I was asking just to be sure there will be no problems calculating color target luminances since there will be not the usual ITU :BT1886 curve.
Thank you!

He's talking about the shareware version.

Did you really need to quote that entire post in your reply?

Hello,

First of all thank you for this great thread that is really full of information.

I recently purchased an LG OLED and I was wondering if I had to set my display type as OLED or should I set it on another type?

I ask this as there are different OLED display types/technologies.

Thanks in advance!

Is there a way to control a DVDO pattern generator with HCFR? If not, hiw can I use it for calibration without having Calman or Chromapure? (I can borrow with)
Thank you!

Hi, I use the EODIS3 with the HCFR (3.1.6) software to calibrate my EPSON TW-9200 projector (5030UB). I´am from Germany and in a German AV forum there are some reports that this combination (EODIS3 and HCFR) causes that the colour red is measured to low and that this causes a reddish picture.
Is something like that already known? Is there any issue?
I would be very grateful for every input.
Thank you in advance.

Best regards

no sorry, HCFR can't control any external pattern generators.

Each probe is a little different and you won't know how much it is under or over reporting a particular color luminance unless you compare it to a spectrometer.

Zoyd thank you for reply, but they report that other software measures correct with the same colorimeter. They controll it with other sensors, so it seems to be a problem with HCFR and EODIS3.

That's all a bit vague but feel free to post data and document any issues in this thread so I can have a look. There have been countless intercomparisons of HCFR, CalMan, and ChromaPure over the years with no significant discrepancies having been found.

Do you have a link to those discussions?

Nothing like that has been reported to me w.r.t ArgyllCMS's i1d3 driver. If you have a specific example, then please point to it.

It seems like one user [ Maxes ] started this idea, and then another [ Nudgiator ] takes that and repeats it later as fact. See the start of the discussion http://www.hifi-forum.de/viewthread-105-2580.html. But as far as I can tell, there is no indication that Maxes or other users reporting similar problems, understands the role that instrument display specific calibration plays in the result. Later in the thread, some other users [ siusebem ] do point this out. Certainly you will get a "too red" result with any colorimeter if you select the wrong spectral sample or calibration matrix, and the way this calibration defaults or is selected will be different for different packages. There are several other examples in that thread of people using the i1d3 with HCFR and not reporting any such "too red" problems, and in fact one seems to report the opposite problem [ Dan_B ] of the Spyder measuring "too red" compared to the i1d3. This is typical of different peoples experience with colorimeters.

I've cross-checked HCFR readings with CalMAN in the past, here is just one example using the display pro. Disagreements are at the instrument precision level.

I meant to ask before and had forgotten. What are the files colors_500.csv and 250.csv for? Was this the reason why I got an error trying to run the skin setting? Have they to be placed in the HCFR main folder?

They are example random color sets. Rename one of them to colors.csv and place in the main folder. Then choose "user" from the color checker drop down to measure them.

Thank you very much, this is the proof that there is nothing wrong. At this point I want to thank you for that great freeware tool. Keep up this good work. Again thank you.

i1 to lend

I've done this before, and it didn't work out well, but I'm willing to try again.
I now have an extra i1 Display LT, purchased in June, 2011. I am willing to lend it out, and I figured this would be the best place to make the offer.
The only requirement is that you have been a member of AVS for at least a year (not a member of the Club [though that would be nice ], just a member of the forum), and that we keep the shipping to the 48 mainland states (and the District of Columbia, for all our friends there ).
It would be considerate if you would limit your "loaner period" to two weeks, and report your results here.
I'll maintain the list here; addresses will be PM'd, so you're only "exposure" will be to the person before you on the list.
First come, first served.
