AMD FreeSync technology synchronizes the GPU and the monitor so frames are displayed when ready: no tearing or stuttering. Experience superb picture quality with advanced IPS technology for vibrant, consistent colours and wide viewing angles. Most LED monitors use PWM (pulse width modulation) to control brightness; the pulsing creates flicker that may cause discomfort, headaches and eye strain, especially in low-light environments. Flicker Free technology uses a smooth DC (directcurrent) backlight system. AOC Low Blue Mode filters harmful short-wave blue light, with 4 levels that suit different viewing situations.
