Gigabit Ethernet is 1 Gbps. HDMI 2.0 bandwidth is 18 Gbps. The HDMI can pass 18x as much data as the Ethernet can on the older standard. HDMI 2.1 bumps it to 48 Gbps. And your internet speed is much faster than average. Streaming content is tailored for connections of 25 Mbps or slower, that’s 1/40th of your speed. Thus, you can see the difference between the two in the table. But, the DisplayPort 2.0 uses the 128b/132b encoding, increasing the efficiency to almost 97%, the rest being used to maintain the signal strength. In the same way, HDMI has also gone through upgrades from 1.0 to the latest 2.1, with 2.0 and 2.0b being used most at present. HDMI 2.0 supports a maximum bandwidth of 18 Gbps, which is enough to handle 4K resolution at up to 60Hz, or 1080p at up to 240Hz. In comparison, DisplayPort 1.4 has a maximum bandwidth of 32.4Gbps, which opens up a much greater resolution and frame rate potential. It supports 4K resolution at up to 120Hz without compression, and 8K resolution The HDMI 2.1 offers greater bandwidth of up to 48 Gbps, which is a major improvement when compared to the previous HDMI versions. This is a major boost to performance because it enables a wide range of features, including higher refresh rates, higher resolutions, and greater color depths. DP 1.2 supports eight audio channels, while DP 1.4 supports up to 32 audio channels. DisplayPort 1.4 is backward compatible with DisplayPort 1.2, so devices with DisplayPort 1.2 can still connect to DisplayPort 1.4 devices. DisplayPort 1.4 supports a refresh rate of up to 120Hz, making it ideal for gaming and other fast-paced applications. HDMI 2.1 was the last major update. It increased the supported bandwidth of the interface to 48Gbps and added support for eARC, uncompressed 8K signal, dynamic HDR, and several next-generation gaming technologies. The new HDMI 2.1a standard is a relatively minor update, but it packs a key feature in the form of Source-Based Tone Mapping (SBTM). The main difference is that HDMI 2.1 increases your maximum signal bandwidth from 18Gbps (HDMI 2.0) to 48Gbps, which enables video resolutions of up to 10K and frame rates as high as 120fps With 4:4:4 chroma subsampling, the refresh rate may go as high as 144 Hz. In such regards, HDMI 2.1 is better as it allows for the output of videos in 4K resolution at 120fps and 8K resolution at 60fps. At 4K resolution, HDMI 2.1 supports a maximum refresh rate of 120Hz, which doubles the frame rate compared to HDMI 2.0. HDMI 2.1: Give me the basics. HDMI 2.1 is a new physical connector that provides a pathway between your content source and your video source, like a TV. HDMI 2.1 is HDMI 2.1 supports 4K@120fps maximum (or 8K@60 .. technically on paper you even go higher than that but). Display Port 1.4 supports 4K120, it sits between HDMI 2.0 and 2.1 in terms of bandwidth. When playing on a 1080p monitor or 1440p monitor, HDMI 2.0 seems to be the good middle ground allowing 1080p240fps max, or 1440p120fps. n7Gconk.
