Just a correction: I checked my madVR settings and I found that I had set "16-235" (only on madVR, in all other places it is 0-255).

Pepelegal: Thank you very much for all the guidance - I will try it now!


On another note, I'd thought I'd give it a go and calibrate my iMac (in target display mode using the PC) with DCG. The strange thing is that I got odd results here as well, once again at low IREs. No artifacts though. Here's all the files: http://s000.tinyupload.com/?file_id=...23385901054840

Low level gamma becomes way too "high" (comes out of black too fast). The calibrated 2.2-profile displays gamma 5 IRE@1,9, 10@2.0 and then it finishes at 2.2 from IRE 40 and onwards. This has me thinking: either the readings are wrong at low IRE (which seems strange since the reader measures correctly (and confirms what I am seeing) in Chromapure) or the applied gamma curve is set wrongly in DCG (it creates a 2.2-gamma at high IRE, but the curve resembles a 1886-gamma that is set "0,2 steps too low", so to say).

Are there any hidden gamma settings in DCG that I can enable? (now I can only choose 2.2, 2.4 and absolute or 1886 (though the absolute or 1886 seems to give the same results (1886-"slope"), i.e. when I choose 2.4, it doesn't matter if I select absolute or 1886, it gives the same results). Because if I could just manually force another gamma response, that would probably take care of the problem.

In the meantime, I will get back to the OLED

And huge thanks for creating such awesome software and all input from everyone else here at the forum!

A DCG beta snapshot update is available.

Changes in 2.9.1.0 beta:
  • When using madTPG during interactive display adjustment, automatically leave fullscreen, and re-enter fullscreen for non-interactive display measurements. Also, if the OSD is disabled, temporarily re-enable it for "put the instrument on screen" messages.
  • Fixed minor quirk of log messages being repeated multiple times in session logfiles (bug introduced in 2.9.0.9).


Changes in 2.9.0.9 beta (never announced, thus FYI):
  • Added a button to create a compressed archive (7z or ZIP) of the currently selected profile and related files.
  • When using Resolve, fixed the possibility of APL pattern background RGB values getting negative (and thus rejected by Resolve, leading to the displayed pattern not being updated) if the test color is bright and the chosen test patch area is large.

Always start from a preset that's appropriate for the job. The profile you uploaded doesn't contain high-quality tables that are needed for a display profile. You can fix this by going into the "Options" menu, selecting "Enhance effective resolution of PCS to device tables" and choosing the existing profile.

Rec. BT 1886 is equivalent to 2.4 absolute with 0% black output offset.

Once I re-enter fullscreen display when running interactive display measurements, and OSD is enabled, a pup up comes up on the left top of the screen that says argyllCMS patches, no count down.
However all seems to work if OSD is disabled except for place meter on the screen patch and no count down.

When running a verification, I don't have to re-enter fullscreen display. The message for place K10 on screen come up and the count down starts.
Works as I would think it should.

btw, why are you asking to place meter on the patch/screen, when using meter in off screen mode?

The count-down only appears in fullscreen when not doing interactive adjustment. It's meant as a work-around for a single-screen situation where both madTPG and the interactive adjustment window have to be on at the same time, i.e. you'd do the interactive adjustment while not in fullscreen.

Because there's no way to detect if the meter is used in contact mode or not.

Yes I know there is no way of detecting on or off screen mode, just wanted to make sure that gwgill didn't make some more magic and need the meter to be on screen.

Tried auto mode (9200+) with calibration (slow), worked very well.
Can you extend the number of patches for auto mode?

Sure. How many patches would you like (roughly)? The next step up would be 11140.

11140 should work.
I am trying to compare with my custom built testcharts. The largest testchart I have used is about 13200.

After viewing the log on the auto mode run, I like how it seems to work.
Is this and the black hack what gwgill was refering to when he said he was making argyllCMS "a little smater".

Thanks.

Ok, I've updated (only) the DCG 0install Windows feed with 2.9.1.1 to unlock this, so you need to update manually.

I tried to choose sensible parameters. Glad to hear it seems to work well for you.

There are many detail improvements, and some new features like this.

There is no difference in LUT profiling or gamut mapping between the march 6 build and the current build.
