Let us take a look at HDMI vs Display Port, what are their uses, differences and benefits?
If you have built or bought a PC within the last few years, you might have stumbled upon a situation where you want to connect your new graphics card to some sort of a display and found that the HDMI cable won't fit! Instead, there's what seems to have been a replacement port for one of your outputs.
HDMI and Display Port serve the same function, for the most part, and that is to transmit audio and video data from your GPU to your display by means of a digital cable.
The latest HDMI cables you can get today is HDMI 2.1, which has a transfer rate of 48 Gbps. And Display Port 2.0 has a transfer rate of 77 Gbps, which is a 62% increase in speed over HDMI.
So the main difference is the rate of data. To put it into perspective, if you run 4K at 4400 x 2250 at 60 Hz with a colour depth of 16 bit, this will require 17.84 Gbps, which both HDMI and Display Port will handle perfectly fine.
Where Display Port will out rule HDMI is on far larger transfer rates such as 8K 120 Hz and 16K 60 Hz.
