Sony has updated the ‘The Ultimate FAQ‘ on the PlayStation Blog to add details on Variable Refresh Rate (VRR) support. The PS5 uses HDMI 2.1 technology, but not all of the features have been enabled yet, with VRR being one of them.
The Ultimate FAQ now indicates that VRR support will be added to the PS5 in a future firmware update, allowing TVs that support VRR to work better with the console:
PS5 hardware supports Variable Refresh Rate (VRR) through HDMI 2.1. After a future system software update, PS5 owners will be able to use the VRR feature of compatible TVs when playing games that support VRR.
VRR means that TVs will be able to adjust the frame rate based on the output of the PS5, instead of locking it to 60 FPS or 120 FPS, which can cause visual defects if the frame rate drops below the set rate.
Even after the firmware updated to the PS5, you will need to own a TV that supports VRR using HDMI 2.1. Unfortunately, it won’t work with TVs that support HDMI 2.0 or older. Sony hasn’t revealed when the firmware update will be available.
