The Acer GD245HQ 3D monitor is full HD (1920 x 1080 pixels) LCD display with 120 Hz support & is certified for NVIDIA 3D Vision. To obtain the 3D effect the monitor displays the alternating left- & right-eye images, at a rate of 120 frames per second. An infrared signal beamed from the IR-emitter induces glasses worn by the viewer to alternately turn of the left & right lenses. The images alternately seen with each eye are combined in the brain, giving the viewer the impression of seeing.
