AMD FreeSync technology synchronizes the GPU and the monitor so frames are displayed when ready:no tearing or stuttering.
Most LED monitors use PWM (pluse width modulation) to control brightness; the plusing creates flicker that may cause discomfort, headaches and eye strain, especially in low-light environments. Flicker Free technology usesa smooth DC (direct current) backlight system.
Why FreeSyn is better
– High performance solution with all the benefits of variable refresh rate technology.
– Basedn on industry standards, not expensive proprietary solutions.
– Cheaper and easier to implement: no additional monitor hardware, no license fees.
