The issue with the ASUS is calibration.
We have been approached by ASUS, but as yet they have no method for accurate end-user calibration via 3D LUTs.
But, why do you want OLED blacks?
They are often too dark, and clip detail.
We recommend any OLED has black set to around 0.03 nits, to prevent grading issues.
