Best answer: To support 120Hz refresh rates, a television needs an HDMI 2.1 port. Though Sony has not confirmed whether the PS5 features such a port, it will have to in order to output 120 frames per second (FPS).
What is the difference between HDMI 2.0 and HDMI 2.1?
HDMI (High-Definition Multimedia Interface) is an interface that transmits video and audio data. The bandwidth capacity of HDMI 2.0 is around 18 Gbps (gigabits per second) whereas the bandwidth capacity of HDMI 2.1 is around 48 Gbps. This means that HDMI 2.1 can transmit more data faster than HDMI 2.0 can.
What resolution and frame rates can HDMI 2.1 support?
HDMI 2.1 supports up to 10K resolution and 120FPS, although not necessarily at the same time. On PS5, you might see games run at 4K/120FPS, but odds are the higher the frame rate, the lower the resolution will be.
The PS5 should be able to support up to 8K…
