HDMI 2.1 :

HDMI 2.1 is the latest edition of HDMI or High Definition Multimedia Interface. This display interface is a multi-tasking tool. It’s used in televisions to connect games consoles and Blu-ray players.

The latest edition supporting a throughput of 48 GB. That’s enough to drive a 10K display at 60 frames per second in full 10-bit color. Because we’re talking about 4K displays, HDMI 2.1 is more than adequate.


DP or DisplayPort was the best choice for years, but this changed after releasing HDMI 2.1, So at the time of writing this article we can say HDMI and specially HDMI 2.1 is better than DisplayPort 1.4.

To be honest, this could change by the end of 2020 as DisplayPort 2.0 expected to hit the market and it can handle a throughput of 80 Gbps in front of 48 Gbps the current HDMI 2.1 introduces.


USB-C is the most common port around the world, but in reale it’s is just DisplayPort via a USB-C plug.

the technical aspects of USB-C DisplayPort over Alt Mode mirror those of regular DisplayPort 1.4. With display stream compression, it’s theoretically possible to get a 4K signal at 60 frames with 8-bit color though 8K resolutions in 10-bit.

But the main reason for choosing USB-C that all modern laptops has USB-C ports so it could be a perfect choice if you need to connect a laptop.


The last and latest port is Thunderbolt that Intel is working hard on it. Thunderbolt also uses the USB-C port but it isn’t a USB-C port.

thunderbolt 3 offers some serious advantages over the latest USB standard, thanks to all that extra bandwidth. It’s possible to run two 4K displays (at 60 frames), a single 4K display (at 120 frames), or a single 5K display (at 60 frames) with just one Thunderbolt 3 cable.

It’s perfect with Mac devices as apple support this technology. On a 2019 16-inch MacBook Pro, two Thunderbolt cables can drive four daisy-chained 4K displays or two 5Ks.

So, if you are a Mac user or want to connect for more than one display, you can try Thunderbolt. But first make sure your device is supporting it.
