Which screen interface is the best?

The technological world is confusing, with alternatives and competition for each and every one of the technological advances that exist. Choosing between different standards is increasingly difficult, since all available options seem similar to each other. One such standard is the screen interfaces. If you are a normal consumer, I am sure that the word display interface will mean HDMI to you. The HDMI standard has become very successful when used in televisions, decoders, Blu-ray players, A / V receivers, game consoles, camcorders and even smart phones.

Given the omnipresence of HDMI, don't blame yourself for not being aware of your biggest competitor: the DisplayPort standard. Like the standard HDMI, both can transmit HD quality digital audio and video signals, including support for High Bandwidth Digital Content Protection (HDCP), which makes them a clear winner of the interface. Media used previously: DVI. But when you put HDMI with DisplayPort, which of these interfaces comes to mind? What is more superior and flexible than the other? We look forward to answering these questions as we approach our version of DisplayPort vs HDMI.

HDMI vs DisplayPort: its history

Specification HDMI (High Definition Multimedia Interface) It was designed in 2002 and put into production in 2003 by six consumer electronics giants: Hitachi, Panasonic, Philips, Silicon Image, Sony and Toshiba. HDMI Licensing, LLC, which is a subsidiary of Silicon Image, now controls the HDMI specification. Any manufacturer that wishes to include HDMI ports in their products you must pay a gift to the enterprise.

Conceptualized in 2006 and finally created in 2008, the DisplayPort specification was developed by Video Electronics Standards Association (VESA), a large consortium of manufacturers ranging from AMD to ZIPS Corporation, including but not limited to Sony, Panasonic, Silicon Image and Toshiba. The specification still remains under the control of VESA only. Unlike HDMI, DisplayPort is a royalty free product.

Connector types

HDMI connectors are composed of 19 pins, But they are available in different sizes. Type A (Standard), is the most used type of HDMI connector, commonly in televisions, projectors, decoders and laptops. HDMI connector Type C (Mini) It is mainly used in tablets and laptops that have a slim profile or ultrabooks. He Type D (Micro) It is also used in thinner tablets and high-end smart phone devices. While HDMI is primarily a consumer-centric product, there is also an HDMI connector of Type E, which is used for automotive purposes.

DisplayPort connectors have 20 pin and are available in only two sizes. He DisplayPort (standard) It is used in business-oriented laptops and desktops, although this trend is definitely changing, with more and more manufacturers including it in their main display devices. A smaller alternative to the Standard DisplayPort, the Mini DisplayPort It is mainly used on Apple devices (after 2013) and Microsoft Surface tablets.

Both HDMI and DisplayPort use friction lock, which basically refers to maintaining a tight fit that keeps the plug connected to the socket. While none of these features has been mentioned in the official standards for any of the interfaces, manufacturers continue to use friction lock together with other patented locking mechanisms that are designed to prevent cables from loosening.

Cables

Let's compare the HDMI and DisplayPort cables, okay?

HDMI cables are generally of four different types, depending on their bandwidth and Ethernet capabilities:

  1. Standard HDMI Cable: This cable is enough to play videos in 720p or even 1080p resolution
  2. Standard HDMI cable with Ethernet: The bandwidth and resolution limit remains the same as standard HDMI, except that this cable also adds support for 100 Mbps Ethernet.
  3. High speed HDMI cable: the bandwidth jumps here, coming to support resolutions of up to 2160p.
  4. High speed HDMI cable with Ethernet: The bandwidth and resolution limit remains the same as high-speed HDMI, except that this cable also adds support for 100 Mbps Ethernet.

There are many HDMI cables available in the market, some of which you can check here.

DisplayPort cables, on the other hand, are of single type . DisplayPort cables can be used to display resolutions up to 3840 by 2160 pixels at a constant refresh rate of 60Hz. In addition, it also supports all 3D video formats. That said, DisplayPort cables cannot carry Ethernet along with the video data bits.

The cables HDMI they don't have specific lengths For your cables, although depending on the material, the lengths may vary. According to HDMI Licensing LLC, the HDMI signals transmitted by CAT 5 or CAT 6 cable can be used for distances up to 164 feet, over coaxial cable for up to 300 feet or over fiber for more than 328 feet.

DisplayPort cableson the other hand, they can stand comparatively smaller distances to keep your screens high resolution. A passive copper DisplayPort cable up to 50 feet and an active copper DisplayPort cable for 65 feet can be used. In addition, DisplayPort has also adopted the growing trend of optical fiber, which allows Fiber DisplayPort cables to transmit data over hundreds of feet.

Video quality

Currently, there are two versions of HDMI in use: v1.4 and v2.0. HDMI 1.4 supports resolutions of 4096 x 2160 at 24Hz or 3840 x 2160 at 30Hz, with a maximum bandwidth of 10.2 Gbps. HDMI 2.0 takes things to the next level, while maintaining the same resolution but raising the refresh rate to 60Hz and also raising the bandwidth to 18 Gbps.

As of 2017, it has been conceptualized a newer version for HDMI – v2.1, but only come into use in the fall. Additional features of this new version will have to be admitted resolutions up to 10K with frame rates of 120 fps, and raise the bandwidth up to 48 Gbps, which represents a great improvement over the only 18 Gbps of HDMI 2.0.

As for DisplayPort, there are also three different versions in use, v1.2, v1.3 and v1.4. DisplayPort v1.2 can support video resolutions up to 3840 x 2160 pixels (4K) at a refresh rate of 60Hz And it is compatible with all common 3D video formats. As for bandwidth, you can manage 17.28 Gbps.

On the other hand, DisplayPort v1.3 can support resolutions up to 8192 x 4320 (8K) at 30 Hz, or two simultaneous 4K streams . It also doubles the bandwidth to 32.4 Gbps.

Finally, the launch in 2017 is expected to be the largest update of VESA, DisplayPort v1.4, which can support 8K video (7, 680 by 4, 320) at a refresh rate of 120Hz, while increasing bandwidth to 40 Gbps.

Audio quality

In terms of audio, there is practically nothing that separates the two, since the latest versions of HDMI and DisplayPort support Up to eight channels of digital audio up to 24 bits and 192 kHz. However the DisplayPort does not have an audio return channel . What it means is that you cannot use your DisplayPort device to send audio data "upstream" to an A / V receiver. In simpler terms, you cannot use a DisplayPort to connect an external sound system to your TV , a feat that HDMI v1.4 and higher can easily achieve.

Multiple screens

Limited to a single audio and video transmission, the HDMI ports allow you to use only one system at a time . While that's great for single-screen users, the current trend seems to lean toward multiple screens.

Initially used by stockbrokers, players and advanced users are making the switch to multiple screens. A single DisplayPort interface can support up to four monitors with a resolution of 1920 by 1200 pixels each, or two monitors with a resolution of 2560 by 1600 pixels. Each screen will receive independent audio and video transmissions. In addition, when using the chain connection in modern GPUs, they can be used Up to six screens in a single source.

Applications

HDMI is primarily developed for consumer electronics applications: Blu-ray players, televisions, video projectors and similar purposes . It has been widely implemented in all media devices around it, and it is very likely that you are already using one.

DisplayPort, on the other hand, is designed as the definitive display interface for computing devices . While it does not attract users for general purposes with individual screens, the ability to connect multiple monitors to your computing device attracts players, stockbrokers, programmers, designers and other advanced users.

DisplayPort vs HDMI: What interface to choose?

Taking into account the main uses of each one, both HDMI and DisplayPort are here to stay and keep growing. Most manufacturers believe that providing an HDMI interface is sufficient. However, as the demand for multiple screens increases, we are slowly seeing greater adoption of the DisplayPort interfaces. While an HDMI port satisfies all your interests, there is no harm in purchasing devices with a DisplayPort as well. Its support for multiple screens and other monitors through adapters gives you greater flexibility compared to HDMI ports.

Well, those were my opinions about the DisplayPort vs HDMI display interfaces, but I would love to know what you think. Share your opinions with us to keep the conversation in the comments section below.
