Yah I read that. Looks like it came back to "normal" after he installed the VESA testing app ? Try removing the app and see what happens ?Well now this is interesting:
Someone with the DWF is reporting clipping in hdr calibration at 1300 in both hdr 1000 and 400 true black with contrast at default 75. Unless there are units shipping with newer firmware now makes me think maybe there is some osd order of operations to run into the firmware bugs or at least some sort of condition to make things bug out?
