In addition, Sony plans to support the variable refresh rate (VRR) feature of the PS5 platform on HDMI 2.1-compatible TVs and PC monitors in the coming months to enhance the graphics performance of PS5 games. Xbox One X and Xbox Series X | S have long supported VRR, compared to vertical synchronization, this technology can completely remove screen tearing, reduce stuttering and latency, and is currently one of the advantages of Xbox Series X over PS5.
Essentially, the role of VRR is to allow two devices to talk to each other more effectively and synchronize with each other. Problems that arise when the device is out of sync are lag (slower response times), flutter (a visual effect of stuttering), and screen tearing, where the image portion of the screen shows visible creases or "tears." By matching the refresh rate of the source device and the display, the delay is reduced to speed up the response time; the motion is smoothed out and the screen tearing is reduced — if not eliminated altogether — because the console/PC waits before sending the next frame, and the monitor adapts to match it. The result is better image quality, as well as smoother, more consistent performance.
