DisplayPort and HDMI are two of the most well-liked port and cable sorts for connecting all types of visible gadgets collectively. TVs connect with video games consoles, displays to graphics playing cards, and exterior shows to laptops, all due to this pair of useful connectors.
Each ports appear to have the identical operate on the floor, which could make you surprise what the distinction is. As ordinary with port know-how, there’s extra happening right here than you would possibly suppose.
The place are HDMI and DisplayPort connectors?

Though each HDMI and DisplayPort connectors are frequent choices, they aren’t present in the identical form of numbers or all the time in the identical place. HDMI is by far the extra mainstream know-how. It helped launch the Blu-ray and HD-DVD industries within the mid-2000s and right this moment may be discovered on nearly every part you’d connect with a TV, together with the TV itself.
Nearly all mainstream TVs launched within the final decade sport a handful of HDMI connections too. The port is such a well-liked alternative of connector for all types of media gadgets in-fact, that there’s a booming enterprise in HDMI splitters andwhich enhance the variety of accessible HDMI ports in your TV.
It’s additionally the principle alternative of connection for gaming consoles from the Xbox One to the PlayStation four, and most desktop computer systems have not less than one among them too. Laptops with a gamer or productiveness focus, such because the Dell G3 Gaming or Dell XPS 15, additionally fairly generally sport HDMI outputs to attach as much as a bigger show.
So, how about DisplayPort? Effectively, it’s remains to be a well-liked connection alternative, however the port itself tends for use solely on PC gaming-focused gadgets and screens. Newest-day add-in graphics playing cards sport not less than one DisplayPort connector. On high-end graphics playing cards like Nvidia’s RTX 2000-series or AMD’s RX 5700-series you’ll discover multiples of them. It’s much less frequent in TVs, however some new large-format gaming screens just like the HP Omen X Emperium have one.
It’s not fairly that straightforward although. The know-how behind DisplayPort, is being tailored in a pair extra locations too. You’ve gotten the mini-DisplayPort, which may be present in some midrange displays and laptops such because the Razer Blade or Floor Laptop computer 2. You’ll additionally discover it hidden in laptops with USB-C that assist the highly effective Thunderbolt three commonplace. It’s a strategy to get all that show energy right into a connector as tiny as USB-C.
Capabilities and options
Each HDMI and DisplayPort supply audio and video over a singular knowledge cable making them easy and versatile connection choices for many types of media, whether or not you’re taking a look at a TV or a monitor. Nevertheless, relying on the model of every that you simply’re utilizing and your specific needs for picture high quality or framerate, it’s possible you’ll need to go for one over the opposite.
There have been many variations of HDMI since its inception in 2002, however it’s mostly discovered right this moment in model 1.four and a couple of.zero. Each requirements can ship 4K video to a show, however HDMI 1.four is proscribed to only 30Hz, which means it could solely show 30 frames per second with out leaving artifacts within the image. That’s completely advantageous for watching films or informal gaming, however most avid gamers will in all probability want a smoother expertise. HDMI 2.zero can deal with 4K at 60Hz, with out issue.
The explanation HDMI is capped on this method is due to its knowledge price. It isn’t large sufficient to assist larger body charges at larger resolutions. That’s the place DisplayPort takes the lead. Its most up-to-date incarnations, 1.three and 1.four, each have knowledge charges that close to double that of HDMI 2.zero, giving it native assist for 4K at 120Hz. With some compression, it could even deal with that at as much as 240Hz, though that’s not its very best use. These newest iterations of DisplayPort may even deal with 8K decision, however are principally restricted to 30Hz.
Exterior of video streams, HDMI additionally helps Ethernet as much as 100Mbit per second and an audio return channel (ARC) which makes it potential to ship audio again to your speaker arrange with out a further audio cable. DisplayPort gives neither of these applied sciences. HDMI additionally tends to work nicely over longer distances, the place DisplayPort’s decision choices decline when you recover from 10 ft.
One benefit DisplayPort does have, although, is its adoption by Intel’s Thunderbolt three commonplace, as talked about earlier. This places it in increasingly gadgets, together with thin-and-light laptops, selecting up DisplayPort 1.2 technical capabilities like 4K decision as much as 75Hz. The primary and second generations of Thunderbolt used the mini-DisplayPort connector. These days, it’s mostly discovered within the type of the USB-C port kind.
The way forward for these ports

Each HDMI and DisplayPort applied sciences have improved dramatically in recent times and that reveals no signal of stopping. HDMI 2.1 was formally introduced in January 2017 and guarantees to just about triple the info price and bandwidth of HDMI 2.zero, nearly doubling the capabilities of DisplayPort 1.four. That may make 4K decision as much as 144Hz greater than potential, in addition to 8K decision at as much as 60Hz (with some caveats). HDMI 2.1 will even introduce assist for different visible enhancements like dynamic HDR for richer colours, variable refresh charges for smoother gaming, a diminished latency for gaming, quicker supply media switching, and enhanced audio.
HDMI 2.1 gadgets might be backward suitable with older HDMI requirements, which means you may join HDMI 1.zero by means of 2.zero gadgets to the two.1 port in your new 8K TV. You’ll nonetheless want new HDMI 2.1 cables to take full benefit of any HDMI 2.1 gadgets you want to connect to it although. We’re simply now seeing the primary televisions with HDMI 2.1 ports launched.
In the meantime, DisplayPort is pushing ahead as nicely. VESA, the technical requirements group behind many show requirements, introduced in early 2018 that the following model of DisplayPort was being developed. Whereas specs have but to be launched, VESA claimed it was concentrating on a doubling of DisplayPort 1.four bandwidth which might allow compression-free 8K video at 60Hz with out issue.
In additional rapid instances, DisplayPort stays a key function of Intel’s Thunderbolt three, which is itself set to grow to be extra extensively adopted due to the long run integration of that know-how with USB4. Though Thunderbolt three solely helps DisplayPort 1.2, that’s greater than sufficient for 4K decision at as much as 75Hz with out compression, which means gadgets like Apple’s MacBook Professional can take full benefit.
DisplayPort can be supported over the USB-C commonplace often known as VirtualLink with an estimated bandwidth equal to that of DisplayPort 1.four. Supported by Nvidia, AMD, HTC, Oculus VR, and Valve, the usual is designed to supply future digital actuality headsets a one-cable connection to a gaming PC for energy and knowledge supply. Nvidia’s Founders Version RTX 2000-series graphics playing cards ship out with the port on their rear panel, although no digital actuality headsets have that port choice presently. Valve might have heralded its demise too, with information that it canceled an adapter for its Index headset that might have supported it.
As of late 2019, Virtualink has an unsure future.
