Displaycal tv calibration11/25/2023 ![]() ![]() Once these choices are made, provided your calibrator and software have no issues, once the new icc profile is generated and loaded into your OS, the colour should be correct regardless of your TV, Phone, or I Pad.If you want them to show accurate colour, have them calibrated to similar standards. A basic editing intent might suggest 100 to 120 cdm2, D65, Native Gamut ( to get the most out of your screen) and a gamma of 2.2 When you calibrate your screen prior to creating your icc profile, you need to decide on the intent and make choices to suit that. to expect one profile to do everything is difficult to say the least. I get that you have multiple uses, I have a screen with multiple profiles for many uses. Of course they say your screen should be the brightest thing in your view, but no one said you should work outdoors ! I have blinds that I use in the "computer room", and I work in subdued lighting simply because no light falling on the screen can alter or influence the colour. 200cdm2 is so bright that if you were using a professional screen, using it at that brightness would cause issues with your warranty on the backlight ! I would say no need to redo that time costly XYZLUT matrix but if you spot some issues in gradients, may be word re doing it, otherwise don’t worry about it.I think it is hard for your screen to be a patchwork quilt, and cover all bases. Usually what I’ve explained above abut Displa圜AL profiles TRC curves “limited” because of LUT truncation caused by another app without a reboot is not an issue. IMHO, the later is the culprit since newer Windows versions seem more prone to those LUT trucation issues. IDNK if this issue is related to graphics cards vendor drivers or to Microsoft. If you want to user i1Profiler later (so you did not uninstall it) for test it in another display, just remember to reboot after it ends its calibration & profiling because it is going to limit LUT precision for ALL apps. Xrite LUT loader is called XRGamma or something like that, I do not remember the exact name.ĭisable them from launching at startup/user logon, then reboot and you are done. There are tools to disable that startup applications like “autoruns” or in modern Windows take a look in “startup” tab in Task manager. You can simply disable those LUT loaders launching, keeping just Displa圜AL loader. That means that TRC curves stored in profile may not be as neutral as you wish, or not as neutral as profile LUT calibration + graphics card actually behave after a reboot or removal of such LUT loader apps. Displa圜AL does its job in a proper way, but OS/ graphic card driver refuses to work in high precision for LUTs. It could also limit futher high precision LUT loading attempts unless you reboot the computer, no matter if you close those other apps before starting Displa圜AL, so when Displa圜AL uses its own loader (high precision) to load 1D calibration into graphics card for its profilling stage… LUT contents may be truncated to 8bit and be measured in that way. I mean, they use its own aplication to load ICM’s profile 1D LUT calibration into graphics card to fix grey/gamma.ĪFAIK all of them use low precision LUT loader which can result in after-calibration banding in grey gradients… even if graphics card can handle high bit depth LUT contents. ) and other calibration tools like Basiccolor Display usually set its own LUT loader application at OS startup/user logon. I1Profiler, its OEM variants (Dell, Viewsonic. ![]() Is that an issue? Should I redo my calibration after uninstalling Xrite? I realized that I did not uninstall the Xrite software before installing Displa圜AL. ![]()
