DisplayPort and HDMI are two of the cable types and most popular ports for connecting all kinds of visual devices. Tvs to gaming consoles, monitors, graphics cards and external displays of laptops, all thanks to this couple of useful connectors. At first glance, both appear to have the same function. What is the difference? As tends to happen with the technology of the ports, it happens here more than you think.
Where there are connectors HDMI and DisplayPort?
Although both are common options, there you will find them in equal amounts and not always in the same place. HDMI is by far the most common technology. Helped launch the industries of the Blu-ray and HD-DVD in the mid 2000s and currently can be found in almost everything that conectarías to a tv.
Almost all tvs, conventional released in the last decade have a lot of connections HDMI. In fact, this port is an option so popular to connect all kinds of multimedia devices, there is a large market of splitters and HDMI switches HDMI that can be used to increase the amount of HDMI ports available on your tv.
It is also the favourite connection of games consoles, from the Xbox One to the PlayStation 4, and almost all desktop computers have at least one. It is also very common that the laptops manufactured thinking of the gamers , or productivity, such as the Dell G3 Gaming or the Dell XPS 15, including outputs HDMI to connect to a larger monitor.
And what about the DisplayPort? It is also a popular choice, although this port is typically used exclusively in devices and screens that focus on the PC for games. Almost all the graphics cards complementary modern come with at least one DisplayPort connector. In graphics cards of high-end, as the series RTX-2000 from Nvidia or the RX-series 5700 of AMD, you will find several. It is less common on tvs, although some monitors recent great format for games, as the HP Omen X Emperium, include one.
But it is not so simple. The technology behind the DisplayPort is also being adapted to some more places. You’ll be able to find a mini-DisplayPort on some monitors and laptops are mid-range as the Razer Blade or the Surface Laptop 2. Also see hidden in laptops with USB-C that have support for the powerful standard Thunderbolt 3. It is a way to carry all that visual power to a connector that is as small as a USB-C.
Capabilities and functions
Both HDMI and DisplayPort provide audio and video through a data cable, so you are connection options, simple and versatile to almost all forms of multimedia content, whether you’re in front of a tv or a monitor. However, depending on the version you use and your particular wishes of image quality and frame rate, you might prefer one or the other.
There have been many versions of HDMI since its birth in 2002, but which we find most commonly are 1.4 and 2.0. Both standards can carry 4K video to a display, but HDMI 1.4 is limited to only 30 Hz, that is to say, you can only display 30 frames per second without leaving artifacts in the image. This is more than enough to watch movies or play once in a while, although most gamers probably want a experience with greater fluency. HDMI 2.0 can work with 4K at 60Hz without any problem.
The reason that HDMI has this type of limitation is that its data speed is not so broad as to support frame rates higher with higher resolutions. Here is where DisplayPort is taking the lead. Their most recent versions, 1.3 and 1.4, have data rates that almost doubled those of the HDMI 2.0, which support 4K at 120Hz natively. With a little compression, you can get a handle 240 Hz, although that is not its ideal use. These new versions of DisplayPort can even handle resolutions of 8K, but are limited mostly to 30Hz.
Outside of video content, HDMI can also work with Ethernet up to 100 Mbit per second and an audio return channel, so that it is possible to send sound to your speaker without the need of another cable. DisplayPort does not offer any of these technologies. HDMI also works well over long distances, while the resolution of the DisplayPort descend when rebasas three meters.
One advantage it does have the DisplayPort is its adoption of the standard Thunderbolt 3 Intel, as mentioned above. This leads to ever more devices, including laptops, thin and light, with technical capabilities of DisplayPort 1.2 and 4K resolution up to 75Hz.
The future of these ports
Both technologies have improved dramatically in recent years, and it does not seem that it will stop. The HDMI 2.1 was officially announced in January of 2017 and promises to nearly triple the data rate and bandwidth of the HDMI 2.0, almost doubling the capabilities of the DisplayPort 1.4. That will make the 4K resolution of up to 144 Hz is more than possible, in addition to a resolution of 8K up to 60 Hz (with some details). HDMI 2.1 will also provide support for other visual improvements such as HDR dynamic, to obtain the most intense colors, frequency of update variables so that the games look more fluid, reduced latency for games, changes faster between content and better audio.
The devices with HDMI 2.1 will be compatible with HDMI standards earlier, so that you’ll be able to connect HDMI 1.0 through devices 2.0 port 2.1 of your new tv 8K, although you will need HDMI cables 2.1 new to take maximum advantage of any HDMI device 2.1 which you want to use. We’re just seeing the first tvs with HDMI ports 2.1.
The DisplayPort also advances. VESA, the organisation of technical standards that is behind many standard screens, announced at the beginning of 2018, that the next version of the DisplayPort-was in development. Although not yet disclosed the specifications, VESA said that his goal was to double the bandwidth of DisplayPort 1.4, which would lead to a resolution of 8K at 60Hz without compression.
Meanwhile, DisplayPort continues to be a key part of the Thunderbolt 3 Intel, looking for a presence more widespread thanks to the future integration of this technology with the USB4. Even if Thunderbolt 3 is only compatible with DisplayPort 1.2, that is more than enough for a 4K resolution at up to 75Hz without compression, which means that devices such as the Apple MacBook Pro can take full advantage of it.
DisplayPort also works with the standard USB-C known as VirtualLink, with a bandwidth equivalent to the DisplayPort 1.4. Compatible with Nvidia, AMD, HTC, Oculus VR and Valve, this standard is designed to provide for future viewers of reality of a virtual connection of a single cable to a PC games. The graphics cards Founders Edition RTX 2000, which include this port, although no viewer of virtual reality has that option currently. In addition, Valve could have announced his death when it announced that it canceled an adapter for your viewer Index that would be compatible. The future of VirtualLink, almost to the end of 2019, is uncertain.
