Review AOC Agon Pro AG276QZD2 240 Hz OLED gaming monitor review: A faster and more colorful revision

Does the new model require the Mandatory Pixel refresh maintenance after 4 hours of use, and can that be accessed by the OSD or only the rear OSD button?
Discussion of Pixel Refresh Maintenance
You can safely disable the 4-hour Pixel Refresh nag screen. The monitor has a power-on counter. When it exceeds 4 hours runtime and you let the screen go to sleep for 2 hours it automatically runs a panel maintenance cycle.
