Abstract

A display system supports variable refresh rates that include a plurality of refresh rates. A source such as a graphics processing unit (GPU) provides frames to the display system at a selected one of the refresh rates. The refresh rates are factored into a corresponding plurality of prime factors. A plurality of numbers of lines per frame in frames provided at the plurality of refresh rates is determined based on one or more ratios of the plurality of refresh rates, the plurality of prime factors, and a line rate for providing frames to the display system at the plurality of refresh rates. The source then selectively provides frames to the display system at one refresh rate of the plurality of refresh rates using the same line rate regardless of which refresh rate is chosen. Furthermore, the number of lines per frame is an integer for frames provided at the refresh rates.
