somehow, today i found my displayCAL doesn’t work any more, i click the tray icon, it shows “Unkown @ 0,0, 2560×1440(Primary); Unknown/unassigned”, I guess the displayCAL can’t detect my monitor, that was why the profile can’t be loaded. I re-installed the soft, but doesn’t help.
after some investigation, it seems displayCAl can’t get the correct EDID, Win10 also can’t recognize the EDID of my monitor, do you guys know why the EDID is lost, the routine update of win10 and amd driver is the only difference since the first time calibration, Is something wrong with my HDMI cable , interface or even the monitor?
