Expect that to change soon, though, as a number of manufacturers announced HDMI 2.1 monitors at CES 2021. Compared to standard HDMI 2.0, DisplayPort 1.4 is superior. DisplayPort 2.0 has also been announced, and it has an even higher maximum bandwidth than HDMI 2.1 at nearly triple the bandwidth of DisplayPort 1.4. HDMI 2.1a is the next iteration of the HDMI standard, and though it doesn’t introduce a major upgrade in bandwidth like HDMI 2.0 and 2.1 did, it does bring with it a unique technology that may make it something worth upgrading for: source based tone mapping. This is an intriguing new addition to the HDMI toolkit, and though it will be The main difference between HDMI ARC vs eARC comes down to bandwidth. Since HDMI 2.1 has a higher bandwidth than HDMI 1.4, it can transfer more data faster. That means the audio signal doesn’t have to be compressed as much, and you’ll get better audio quality with eARC. You can think of bandwidth like a pipe that can only transport a The difference between HDMI 2.0 and 2.1 is pretty noticeable too. A PS5 game, running in 4K at 60fps (or 120fps) will look and play magnificently compared to 4K at 30fps. HDMI 2.1 allows for high resolutions such as 4K (3840x2160), 8K (7680x4320), and even 10K (10240x4320 in a 21:9 aspect ratio). The previous HDMI 2.0b specification only allowed for a max of 4K Maximum supported resolution. HDMI 1.4 supported 4K resolution at 30 FPS, while HDMI 2.0 raised the bar to 4K at 60 Hz or 8K at 30 Hz. The latest HDMI 2.1 standard takes it even further, enabling HDMI 2.0 vs HDMI 2.1. HDMI 2.0 is capped at 4K at 60Hz, whereas HDMI 2.1 performs at 4K up to 120Hz and 8K at 60Hz. HDMI 2.1 is preferred for intensive display. About the Author. The big jump to 2.1. HDMI 2.1 is the upcoming update, and it is a significant jump. It takes everything from 2.0b and adds insane things like 10K resolution at a whopping 120Hz, far beyond GF150.
