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.


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.
