HDMI 2.1 increases the speed of the interface to 48Gbps. Enabling it to carry 8K video at 120Hz, or higher with display stream compression. This standard also enables the eARC sound connection and things like auto-low-latency and variable framerate that are useful to gamers.
In theory, though, HDMI 2.0 (effectively HDMI 2.0b since late 2016) can do 4K 120Hz. This mostly applies to PC, where cards like the GTX 2080 Ti can actually pull off 120 frames per second in certain games while running in 4K.
You need to connect your 4K 120Hz source devices like a PS5 or Xbox Series X specifically to the HDMI 2.1 ports on your TV. HDMI 2.1 has enough bandwidth for uncompressed 4K video at up to 120Hz refresh rate. Many 4K TVs only have 1 or 2 HDMI 2.1 ports, while the rest are older HDMI 2.0.
HDMI 2.1 cables have significantly higher bandwidth compared to previous versions, allowing them to handle the immense data requirements of 4K at a 120Hz refresh rate. When it comes to purchasing an HDMI cable for 4K 120Hz, it’s crucial to look for the “Ultra High-Speed” certification.
However, the main advantage of having HDMI 2.1 support on a 4k TV is that it can support 4k @ 120Hz content, which is what the newer gaming consoles output. The following table covers most of the new resolutions and refresh rates permitted by HDMI 2.1.
Current Sony models with 4K 120Hz support are the Z9J 8K models (on two HDMIs), the A90J 4K OLEDs (on two HDMIs), the A80J/A84J 4K OLEDs (on two HDMIs), the X95J/X94J 4K LCDs (on two HDMIs), the X90J 4K LCD (on two HDMIs), and the X85J 4K LCDs (on two HDMIs).
Does HDMI support 120Hz? Yes. Is it the best connector for 120Hz? Not necessarily. If you're running a graphics card from 2018 or 2019, chances are it comes equipped with a handful of DisplayPort options alongside a single HDMI 2.0 connector. If you've tried HDMI 4K 120Hz and found it lacking, then DisplayPort is your answer.
HDMI 2.1 supports 4K, 8K, and 10K signals at up to 120fps, best for gamers with modern consoles and GPUs. The standard also introduces support for dynamic HDR technologies like Dolby Vision, and HDR10+.
With HDMI 2.1, we can get 4K at 120Hz, 8K at 60Hz, and up to 10K resolution for industrial and commercial applications.
HDMI 2.0 and 2.1 Refresh Rates. HDMI 2.0 can handle up to 240 Hz when using 1080p resolution, 144 Hz when using 1440p resolution, and 60 Hz when using 4K resolution. HDMI 2.1 cables can handle up to 120 Hz when using 4K resolution and 60 Hz when using 8K resolution.
