![]() ![]() But you can’t do it on a tv really unless you get a separate box or computer to drive them. I used it to calibrate my plasmas and oleds the same way. So you MUST calibrate with ‘windows’ ie windowed greyscale/color slides NOT full screen slides.ĭid a lot of testing. To use hcfr, it needs needs the generic driver, not the datacolor one, and you need the latest version of hcfr:įor calibrating tvs like oled and plasma you need to use ‘windowed’ slides as the display automatically limits brightness throughout content (also known as ABL). ![]() This is just the way spyderx is-it is more accurate in wide LED mode for every display regardless. ![]() in hcfr, set the spyder to ‘wide led’ which is what it is most accurate as, even if the display is a different type. Set video card output to the tvs color and video limitations and don’t let it do any kind of processing other than that. With SDR TVs, calibration is based on matching the TV as closely as possible to a given standard, such as Rec709 with a power law EOTF (we do not recommend the. i use hcfr to calibrate and to generate test patterns. 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.Yes, you can use hcfr, chroma pure, calman etc. 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. Since A1 does not have an internal 3D LUT capabilities, I’m trying to create the LUT with Resolve’s own pattern generator, connected via Decklink Mini 4K. ) and other calibration tools like Basiccolor Display usually set its own LUT loader application at OS startup/user logon. So I’m trying to calibrate an LG OLED A1 by creating a 3D LUT (gamma 2.4, 709, 100 nits etc.) with i1 Display Pro and can’t seem to get it done. 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. ![]()
