![]() ![]() ![]() Sounds like calibration and profiling is happening in non-HDR mode, and then the calibration LUTs are being applied in HDR mode. My theory goes something like, “the LUT table is interpreted in HDR space not in SDR space”, but I’m not really sure… I’m not sure if this is a bug in W11 HDR mode, or if its an artifact of how HDR works. The issue I’m having is that the video card LUT that’s created, while targeting sRGB at D6500, is coming out at 7000+ CCT when verifying the profile and when reporting on the calibrated display.ĭuring refinement passes, does Argyll actually measure the results of applying the LUT values so it knows how much to increase or decrease them by? My theory goes something like, “the LUT table is interpreted in HDR space not in SDR space”, but I’m not really I’ve been using Displa圜al to create monitor profiles for Windows 11 in HDR mode on my OLED laptop. I was wondering if you guys have any thoughts on what’s happening? During refinement passes, does Argyll actually measure the results of applying the LUT values so it knows how much to increase or decrease them by? While this works reasonably well, it is a clunky work-around and results in calibrations that are of lower quality. I then incorporate this corrected LUT into a new profile. So if the default LUT value for red at index 255 is 65535, and the calibrated value is 65531, the “corrected” value would be 65534 and so on for each LUT table index. I’ve worked around this by reducing the difference between each default LUT value and the calibrated LUT value by a factor of 4. The issue I’m having is that the video card LUT that’s created, while targeting sRGB at D6500, is coming out at 7000+ CCT when verifying the profile and when reporting on the calibrated display. Whereas Spyder 4 TV HD is to my knowledge the only colorimeter for TV calibration.I’ve been using Displa圜al to create monitor profiles for Windows 11 in HDR mode on my OLED laptop. I specifically meantioned Spyder 5 Express because it is to my knowledge the cheapest colorimeter you can buy. One popular alternative software is Displa圜AL, but I have not used it myself.ĭisclaimer: I am in no way affiliated with Datacolor. Express obviously has the most limited software. Only the software and maybe what they bundle with the device differs. Datacolor does have a different product specifically for TV calibration though, Spyder 4 TV HD.įun fact: All Spyder 5 devices (Express, Pro, Elite, Studio) are exact same device. Which limits usefulness of calibration on TVs. Even if TV calibration does work, the ICC profile is stored on the computer on which calibration was made. I do not know whether this is an issue with all TVs. I tried to calibrate my TV, but calibration failed because the TV didn't send some data required for calibration. The video shows the Elite model, which has more software options than Express.Īttempting to calibrate a TV using HDMI may not work. Here is a YouTube video demonstrating how to use Spyder 5. I've personally used Spyder 5 Express at home and at work to calibrate 7 displays in total, and it makes considerable difference. More expensive colorimeters have more options, but Spyder 5 Express should be perfectly fine for the people who don't do image-/video editing work. Then let the colorimeter do calibration for you. How it works? In monitor OSD settings you first reset settings, then select brightness that best suits you. The cheapest colorimeter at this time to my knowledge is the Datacolor Spyder 5 Express. Therefore, please make a reasonable investment in a colorimeter rather than suffer from poorly calibrated monitor. Same settings on another display of same brand and model and same GPU will yield different results. I am quite baffled by how so many people are willing to spend significant sum of money for a monitor, but neglect proper monitor calibration.Īsking for calibration settings, ICC profiles and whatnot is mostly useless because they vary between each individual monitor and GPU.
