там же написано что vg248qe - flicker free, но это не так:
Keep in mind that the ASUS VG248QE monitor is not flicker-free as it uses PWM to regulate brightness. It also doesn’t have a low-blue light filter, so if you are sensitive to screen flicker, you may encounter headaches and/or eye fatigue after longer use of the monitor.
