In this article we will see what are the main features and differences between HDMI and DisplayPort.
DisplayPort and HDMI – Differences and Features
Let’s start with the shape and size of the connectors. While HDMI is symmetrical, the DisplayPort is not, although they are both similar in size and shape.
Both are used to connect a video output to a video input, i.e. from the PC graphics card to a monitor. But not only because, they are also used to connect laptops and other devices that integrate them, always to a video output that is a monitor or a screen.
HDMI is much better known as a port, also because it has been on the market for longer, it began its wanderings in 2002 with version 1.0, while DisplayPort arrived later, in 2006.
In all of this, over time, DisplayPort has prevailed over HDMI in some respects and vice versa in others. We would like to clarify that it is advisable to compare the versions that are usually seen on the market from 4 or 5 years ago until today since the previous versions are no longer found in any type of current monitor.
Today we usually find monitors with HDMI 2.0a, 2.0b and HDMI 2.1, which in turn can also incorporate DisplayPort 1.2, 1.4 and 1.4a.
Although DisplayPort has its version 2.0, it is not found in monitors or graphics cards because it was announced relatively recently by VESA.
There don’t seem to be any manufacturers who dare to launch products with this standard as, for the moment, it doesn’t seem to be necessary.
But let’s see below what are the main features;
Special features of HDMI and DisplayPort
Here is an explanation that differentiates the various models, and what is the meaning of the acronyms that we can find on the various devices on the market
HDR: High Dynamic Range, is becoming fashionable on many monitors and offers much higher color levels and palette depth than usual. Amazing colors.
DSC: Display Stream Compression, an algorithm for compressing colors that the human eye can barely distinguish. Results in higher resolutions without quality loss.
VRR: Technology that varies the monitor refresh rate to match that of the graph. It’s done natively, so there are no game/monitor/software incompatibilities or anything like that.
Replay Panel: Technology that significantly reduces the consumption of graphics, since only the part of the screen that has been updated is updated. A good part of the image rendering is saved, especially for static environments (office automation, web browsing …)
