What I found interesting before using the Samsung LED entry, it was causing the low greyscale to come out a bit blue. Rather than neutral with the default setting for the i1 Display Pro.

vega, to get my i1 pro /dtp 94 working correctly, sometimes I'd have to choose the correct meter from the pulldown menu in HCFR - there'd sometimes be two options for each meter - e.g. xrite i1 pro or gretag macbeth i1 pro.

Not sure if this issue persists in later versions of HCFR, but it might help u.

That's what worked for me....

Still don't know if it's related.

tried it both ways, no go. I still cannot find what has changed, all worked fine last time I used it.

Have you tried using a different USB port? Win7 seems to allow using different drivers for each port for the same device and it will remember the driver-port-device combination.

Hi,

I just got a ColorMunki Display which I am now fiddling/playing with under the new HCFR.

I have a couple older Samsung CCFL LCD displays (model years 2007-2009) and am wondering which Display Type is best under the i1d3/ColorMunki Display meter configuration options. Is LCD CCFL IPS the one to go with or should I just leave it at the default of Non-Refresh display? Grayscale runs on one of the sets showed there wasn't much difference between the two settings - at least not enough for the naked eye to discern. I was also assuming that the LCD CCFL Wide Gamut option would not be the optimum choice for these displays. Any help is appreciated.

cheers,

I've tried all 6 with no luck. One difference I see on the system with the communication failure, when I click on calibrate, a "skip white tile calibration?" dialog appears, which does not on the working system.

 

Anyone else getting this dialog?

I believe I have a problem with the argyll driver. I've tried everything I could fing on the argyll and dispcal sites, no luck.

 

Got desperate, and installed hcfr 2.1 which uses the x-rite driver, everything works.

 

Anybody got any ideas as to how to correct the argyll driver? or know if it has a conflict with any other drivers, video etc?

post #3280 of 3445
Well,

I dl-ed the argyll driver and then used device manager to update it. Of course, I'm talking about a 8 to 10 year old XP laptop.... I"m not sure my help is relevant to your system.

One reason I have such an old system is I "need" the com port for another calibration program and com ports r getting rare.

Isn't 2.1 like so old it doesn't support i1 Display3?...

I'll find out soon enough .......... I have a set to calibrate for a friend this week, and I'll need both meters working to create a matrix for the i1display.

 

On a side note, I was in the same situation with my old laptop, needing com ports. It finally died, and I was forced to upgrade. I now use the USB to RS232 adapters, they work with everything I use, including ControlCal.

 

thanks again to everyone ..........

Samsungs are definitely not IPS...why not try wide gamut CCFL and see if it measures considerably wider (or at all) than non-refersh type...

zoyd,

 

Thank you very much for this HCFR version.

MUCH MUCH better than the final official release.

 

I can finally calibrate my TV to a custom white point.

Then, based on the actual Y reading for white, I manually edited the Y reading until the target Y was achieved (luminance bar graph on bottom left) for primaries and secondaries. With that done I had an HCFR window open with correct xy coordinates and Y target for may particular display. I disabled data editing and set that window as "reference". In the table at the bottom left of the window, you will then have the target RGB readings for the correct xyY targets.

Ok, I know rec709 xy coordinates for 100% , but where do I find the xy coordinates for 75% primary and secondary colors?

If you know the D65 coordinate and the primary coordinates, you should be able to use linear algebra to interpolate the 75% point (assuming 75% is defined as 75% of the physical distance in that space from D65 to each respective primary).

I'd have to brush up on my linear algebra to do it, but it shouldn't be too hard. Lemme know if u can't figure it out, if I have time I'll see if I can calculate it.

Or, you may simply put the mouse arrow on the 75% saturation point on the CIE diagram and it will show you the reference values for that point.

I don't remember where I got this -- probably zoyd.

Thanks - the wide gamut one is also listed as IPS actually. I'm guessing that it's fine to use the regular CCFL one for CCFL LCD panels.

Ha! that was the simplest way! Thanks!

Larry,, that spreadsheet seemed interesting, will have a look it later, seemed to contain a lot of stuff.

Some interesting debate on BT.1886 and 2.2 power gamma on the other thread.

So, how do you tell HCFR to measure/calibrate on 2.2 power ?
post #3291 of 3445
Thread Starter 
2.2 approximates BT.1886 at 10% video level for some displays but generally is too dark for near-blacks (< 5%) and too light for midtones. To calibrate to it in HCFR choose Display gamma as reference and enter 2.2 in the reference box. The target gamma line will reflect a pure power function with exponent 2.2

Thanks Zoyd.

I've slipped in two more fixes to the 3.1.0.6 package. The first has fixed the issue that vega509 was having with i1pro communication and the second fixes the wavelength scale on spectral plots for i1pro in hires mode and the JETI. Let me know if you encounter any other problems.

drinks are on me zoyd,

 

thanks

post #3295 of 3445
You are amazing, thanks for this.

How do i update? Remove and re-install or just install in place?
post #3296 of 3445
Thread Starter 
You can install over the old one.
post #3297 of 3445
thanks and sorry for petty chatter... I'm sure now either way would work.

Thanks again so much... Commercial packages are good and cheap now. I've always liked ChromaPure and would love to buy it but the reality is I'm better off with a new bulb purchase instead and resources are such that I have to make choices.

Having AVS709 and HCFR available free keeps me "in".

hi Zoyd, do you have a pointer to the formulas used for these?

thanks!

The dE formulas can be found at brucelindbloom.com, those options you quoted are for how the reference or target white is treated when converting to Lab coordinates.

Thank you,
