Calibrate for Decklink

PostThu Oct 10, 2024 8:25 pm

How do we calibrate for Decklink? I was misled about this Calman Home for LG and built my suite around it only to be told by Portrait Displays that, no, it doesn’t actually work with Resolve (contrary to their false advertising that it does.). Apparently to calibrate for Resolve, you have to pay them thousands of dollars more.

So is there affordable software to calibrate for a clean feed? I don’t want to go down the rabbit hole of paying someone every 6 months.

Try DisplayCal: https://displaycal.net

Thank you for the suggestion, Uli. I'll give it a shot.

I don´t know what you mean by that. I use Calmy Home for LG and my OLED is plugged to a Intesty Pro 4k. If you calibrate for REC 709 and set up your project for REC 709 then that´s what's coming out of the IO. So no need to calibrate through Resolve. That´s the good thing about IO cards. They give out REC 709. It works perfectly like this.

That's correct: digital is digital. If you feed digital test signals via HDMI (or HD-SDI) to any monitor, then calibrate it with Calman or Light Illusion, the monitor is calibrated... period. Once you hook it up digitally to a Blackmagic display device, the levels should not change unless something is seriously wrong. We do take a look at bars and grayscale after calibration to just verify that the performance is fine, but it's rare I ever have to touch anything.

I did test and compared the decklink and a Blackmagic Hyperdeck running an export of the same project and the colours are identical. So the Decklink and the Hyperdeck output clean REC709 and I think most media players do exactly this. I use a lot of Brightsign Players too. in the moment I edit multi channel video and set up 2 LGCX 48 next to each other. After calibration with Calman for LG they look identical. Before was a big difference. I split the signal through a Terranex 12g SDI to 4x3g SDI.

Do you by chance have a tutorial for this? Portrait Displays told me directly that Calman Home for LG does not calibrate via Resolve. There is no Resolve option in their software like there is with DisplayCal (which is not only free but also simpler with a much better UI.) Is the Intensity a pci-e card? Resolve will only output via the Decklink from Resolve.

It would stand to reason that connecting the LG via its IP address would send out a clean signal similar to the Decklink. But as Portrait Displays (who wrote the Calman software) told me that their software does not work with Resolve, I have to question that reasoning. To be clear, I am not a calibration expert (really???). I'm just going off of what the experts tell me.

There´s no need to calibrate through resolve. just follow the walkthrough of Calman and some settings are important on the tv. you need to get a service remote and switch off the dimming in the service menu. you will lose your warranty. then on the oled menu make sure you switch everything off like sharpening and motion related stuff or denoising. use cinema preset for example. once the calibration is done you have a hardware calibrated monitor that is showing you perfect REC 709. My OLEDs have delta average of below 1 which is broadcast level.

here you see how you can switch off the internal dimming and how the process works



I think there is a misunderstanding of you how hardware calibration works. the calibration will be saved inside the monitor and every source that you plug to the port you calibrated and outputs REC709 will be perfect.

just make sure you switch off the dimming and get this remote for 10 bugs and make sure you set the tv to video levels / limited / or dark black or what it´s called in the tv. run the clip from Calman during the calibration and when it´s down select the preset you calibrate for example Cinema ( custom ) or so.
