I’d like to cc some photos and maybe a video sometimes with my “basic” Samsung 4k-tv from 2017 (UE49KU6645U, edge lit I guess, Samsung does not tell a lot).
I have i1display(3) to use, but no software with it.
Samsung has in it’s settings a “white balance” setting that has 2-point or 10-point adjustments.
I mainly just want to calibrate the tv to it’s best use with all of its flaws and limitations.
All “picture enhancements” in tv has of course been set off.Adjustable points in 2-point “white balance”:
r/g/b-offset and r/g/b-gain.Adjustable points in 10-point “white balance”:
interval % and then r/g/b value (for each percentage?)I guess I will use it with full backlit and with brightness set to 45 white point seems to be 123cd/m2 or with 50 130cd/m2. Black points with those are 0.03 and 0.05 cd/m2.
All those are good enough for me.I prioritize color over sharpness, so I’m not sure if I should use “UHD colors” (12bit 4:2:2 if M1proMBP supports it) or regular 8-bit 4:4:4.
I do know basic things about color management.
Maybe the tv should be set to gamma 2.4, because I could watch blu-ray content from my computer?
Is there a better free (or very cheap) software to do that 10-point “white balance” calibration than DisplayCAL?
There’s no pattern generator in DisplayCAL to do that 10-point calibration?
Just noticed that when HRD is set on on mbp, the desktop background colors are still SDR.
So, when you set HRD off, the white background goes to 340 cd/m2.Yep.
I’m a mac guy.
But I have few old windows-laptops somewhere.So, HCFR would be goog for calibrating, since DisplayCAL does not focus on that?
HCFR (free), ColourSpace ZRO (cheap).
Both Windows only though.
If I’d wanted to calibrate in HDR, I need a computer that can feed out HDR?
DisplayCal is designed for monitors where you calibrate the display by altering the signal the computer produces.
Calibrating a TV using the controls it provides is called manual calibration. HCFR is designed for this as it makes it easy to measure individual points, in whatever order you choose.

Yes. I have called “calibrating from computer” a profiling.
The problem there is that you are cutting away that number of colors that are already scarce if using 8-bit colors. I hate banding.Problem here is now, that I would need a new windows laptop to make HDR “manual calibration”. Since samsung needs to get HDR signal to be in HDR mode.
Consider buying a raspberry pi to get rid of whatever you macbook is doing to the signal (SDR/HDR..) going to the TV. You have PGnenerator OS for raspebrry pi for free in AVSforum.
Then you can use several tools like HCFR to communicate with the pi and send color patches to TV matching those 10points for greyblance, reading deviation for each one and correcting them, measure again till all is OK.Consider buying a raspberry pi to get rid of whatever you macbook is doing to the signal (SDR/HDR..) going to the TV.

Raspberry pi 4 can. I forgot to say that Pi5 is not compatible with PGenerator.
Please search in AVSForum the thread dedicated to PGenerator.People use HCFR, Calman, Light illusion apps, and some user made lightweight apps like Pgen (https://www.avsforum.com/threads/pgen_client-open-source-calibration-gui-for-pgenerator.3294601/) to talk with PGenerator and to the measurements.
Old Pi like pi rev B or pi 3 can use PGenerator for SDR, although GPU memory limitations may not allow to show “test images” (like gradients). For HDR you’ll need a pi 4.
Pi is configured in full range always (like SDR 0-255). Then each software sends full or limited values over full range connection to match whatever your display or TV is expecting. This way Pi is “transparent” and signal configuration is up to apps talking to Pgen. Works very well.

Please search in AVSForum the thread dedicated to PGenerator.What RAM version would be needed for this?
I greatly appreciate your advice!

IDNK , ask in AVSforum. Mine is 8GB but I use it also for other task by switching mSD card with OS. Maybe 4GB is safer than 2… but IDNK
