HDMI 2.0 is a technology developed by the HDMI Forum. First introduced in September 2013, HDMI 2.0 includes increased bandwidth up to 18 Gbps, resolutions up to 60K at 4 Hz, simultaneous transmission of two video streams and up to four audio streams, 32 audio channels, and other significant improvements.

Backwards compatible with previous versions, HDMI 2.0 is designed to enhance the video and audio experience for viewers. HDMI 2.0 increases bandwidth to 18 Gbps and adds significant enhancements to support emerging requirements such as higher resolutions and multi-stream sending. So how many Hz does HDMI 2.0 support?

How many Hz does HDMI 2.0 support?

From a visual perspective, HDMI 2.0 looks like a real hero. With 12-bit color depth, it illuminates each pixel to its full capacity. The Hz amounts supported by HDMI 2.0 are as follows according to resolution:

  • 1080p (FHD) 120Hz
  • 2160 (UHD) 60Hz
  • 1080p 3D 120Hz

As you can see from the list above, HDMI 2.0 on a 4K TV or monitor only supports 60Hz. For 120Hz, the screen must be Full HD.

Does HDMI 2.0 support 120Hz and 144Hz?

It can support higher refresh rates of 120Hz and 144Hz. However, relying on this high refresh rate will result in degraded video quality. Therefore, we can say that HDMI 2.0 and HDMI 2.0b improve the visual experience up to 144Hz, but they do not guarantee a silky smooth video quality stream.

Hz values supported by HDMI 2.0: 720p 30Hz, 720p 60Hz, 720p 120Hz, 1080p 30Hz, 1080p 60Hz, 1080p 120Hz, 1080p 144Hz, 1080p 240Hz, 1440p 30Hz, 14 40p 60Hz, 1440p 75Hz, 1440p 120Hz , 1440p 144Hz, 1440p 240Hz, 4K 30Hz, 4K 60Hz, 4K 75Hz, 4K 120Hz, 5K 30Hz, 5K 120Hz, 8K 30Hz.

HDMI includes support for HDCP, an encryption protocol for copy-protected video content. Like all other versions of the HDMI specifications, HDMI 2.0 is backwards compatible with previous versions. HDMI 2.0 is an enhanced version of the specification and is a successor to the HDMI 1.x versions. To use, both the receiving device and the source must support HDMI 2.0.
