Hello everyone! Yesterday I tried to make ICC profile for ASUS VivoBook X570UD display, I made several attempts for L*a*b* LUT, XYZ LUT and “quick” curves+matrix types playing with white and black points level and blacks correction too. No usable result was achieved. There’s some hardware problem that is difficult to catch with eye, symptoms are:
- DisplayCAL significantly lowered brightness, from 270 cd/sq.m to ap. 140 to try to correct white point.
- Tonal curves have steep ends without black luminance correction and are simply harsh or raggy with it (!!!).
- Calibration curves are approxiamtely the same for different white luminance correction and black level is as high as 51 of 255 RGB for 6 cd/sq.m
- I saw some static spots of green noise in a black field on that display and, probably, some little flashing, light also floods well in display plastic.
All Intel 620 automatic settings (including power adoption) were off. It seems that pixel response show something terrible (even for 70 ms setting). Generally the display is weak for color works, it has carrot red color and ColorMunki shows low sepparation for green and red lightning. I tried ColorMunki and i1Pro 2 both. I have some experience with DisplayCAL and Argyll toolset, so I’m not green, neither professional in colors. Yesterday later I made good ICC for Xiaomi Pro, so my “xrites” work well. Does anyone know this problem? Curves and screenshots are clipped in.
Probably some sort of automatic dimming. If you cannot turn that off, this display is not suitable for calibration and profiling.
Thank you, Florian! But could it be Asus Splendid or DisplayCAL disables it completely? Do you know, does Splendid change square spot color without changing surrounding image? I have not seen surrounding flickering during measurement. Also, have you met real examples of such dimming type in last years,?
