Quad12x: 1440Hz greyscale, half resolution
In Quad12x mode, also known as 1440Hz mode, video is passed from the GPU to the display with a resolution of 1920 x 1080 p @ 120Hz.
The custom sequencer converts the R, G and B colour planes into three greyscale images, then divides those full resolution greyscale images into four 960 x 540 “quadrants.” The twelve subsequent greyscale quadrants are displayed sequentially, yielding a final refreshrate of 1440Hz.
All quadrants are displayed full-screen, greyscale.
Links to examples of Quad12x from our demo library can be found below. We also have a new guide to Rapid Invisible Frequency Tagging (RIFT) using the PROPixx 1440 Hz mode, which includes a working demo and step-by-step explanations.
