HDMI 2.0 and HDMI 2.1 differ in video resolution and compatibility as shown: HDMI 2.1 Vs. HDMI 2.2: Video Resolution. HDMI 2.1 supports both 4K and 8K uncompressed content. The high resolution allows you to see clearly and sharper images. Also, it shows more details on the screen.
HDMI 2.1 almost triples the bandwidth speed from 18Gbps to 48Gbps. The HDMI 2.1 connector will work with HDMI 2.0 ports, but the cables will not improve the performance of older devices. Gamers are the first group that will see the benefits of HDMI 2.1 with smoother animation and reduced lag. High-definition technology has been the standard in The refresh rate that is supported by HDMI 2.1 is higher than the one supported by HDMI 2.0. To be precise, HDMI 2.1 is designed to support the refresh rate of up to 8K at 60Hz and at the same time 4K at 120Hz. On the other hand, HDMI 2.0 supports a refresh rate of 4K at 60Hz. The difference is quite big.Hdmi 2.1 supports every high resolution to 8k 30fps and any fps as of 120fps for 4k or under Hdmi 2.0 goes as high as 4k 60fps and the only high fps for hdmu 2.0 is 1080p with 120fps. Hdmi 2.1 will just use 1080p at 60fps for the ps3 like hdmi 2.0. 1. r/PS3.
VRR is not dependent on cable. DisplayPort to HDMI won't work, wrong direction, they can only do DisplayPort input from PC, to HDMI output for monitor. They will black screen no signal when trying to go wrong direction. Look for HDMI to DisplayPort, so it can do HDMI input from PS4/PS5, to DisplayPort output for monitor.Where HDMI 2.1 supports a maximum bandwidth of 48 Gbps, HDMI 2.0 is only capable of a mere 18 Gbps. HDMI 2.1 vs HDMI 2.0 cables on max effective data rate is a similar wash, with HDMI 2.1 supporting up to 42.6 Gbps, whereas HDMI 2.0 manages just 14.4 Gbps. All that additional bandwidth opens up the HDMI standard to higher resolutions and
