    Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for synchronized dual eye variable refresh rate update for a VR display. A display processor obtains an indication of a synchronous flush or an asynchronous flush with respect to a first DPU and/or a second DPU. The display processor determines whether a first flush operation and/or a second flush operation is available at a time instance, where the first flush operation and the second flush operation are associated with the first DPU and/or the second DPU. The display processor performs, based on a VSync instance, the first flush operation and/or the second flush operation based on whether the first flush operation and/or the second flush operation are available at the time instance and based on the indication of the synchronous flush or the asynchronous flush.
