    Hello,

    Trying to calibrate my SmallHD702 using Davinci as the pattern generator. Running Display Cal 3.8.9.3 with Argyll v2.3.1 with iDisplay as the probe attached to a USB3.0 input. I’m running this whole set up on windows 64-bit operating system, x64-based processor. The monitor is receiving signal from an SDI thru a blackmagic decklink.

    It keeps coming up with the same error. Error – display read failed with ‘Window Access Failed’. I have ran this exact set up before and it has worked. I just thought it’s time for a new calibration.

    I have attached the log file for reference please help. I’m losing so much sleep over this.
