It is more important to look at the version number (on both the source and the display) than to compare DisplayPort with HDMI. In other words, it is more important to look at the version number (on both the source and the display) than to compare DisplayPort with HDMI. The most used HDMI-version, HDMI 2.0, features UHD resolution at 60 Hz and a bandwidth of 14.4 Gbps. DisplayPort 1.4, supporting 5120 x 2800 at a bandwidth of 25.92 Gbps, is becoming increasingly popular. The maximum bandwidth to be sent through a DP 1.2 cable is 17.28 Gbps. It also supports all common 3D video formats. In the movie industry 4K implies a resolution of 4096 x 2160, by the way. The official name for this resolution is by the way UHD, but the term 4K is often used as well. Today’s most common version (for video wall displays), DisplayPort 1.2, supports video resolutions of up to 3840 x 2160 pixels, at a refresh rate of 60 Hz. If not, you will be paying more for something you cannot use. The most important thing is that the standard matches the needs of the display. It doesn't make much sense to include a standard that supports 8K resolution on an HD display. This however does not mean that a new display always supports the latest version of the standard. Resolution and bandwidthĮvery new version of both the HDMI and DisplayPort standards typically introduce some minor new features, and higher resolution and bandwidth. Though most full-size DisplayPort connectors have a locking mechanism that prevents them from being disconnected accidentally, this feature is not required by the official specification. The latter is the same port as Thunderbolt. There are two sizes available: the standard DisplayPort and a smaller alternative made by Apple called Mini DisplayPort. Such mechanisms are a lot more common in DisplayPort solutions.ĭisplayPort connectors have 20 pins. The other HDMI connectors commonly use friction to keep the plug into the socket – although sometimes locking mechanisms are used that prevent the cable from pulling loose. The lesser known Type B (29 pins) is used for dual-link applications, whereas Type E has a locking tab to keep the cable from vibrating loose in automotive applications. The 19 pins HDMI-connectors are actually available in 5 shapes, but only 3 of them are commonly seen: the well-known Type A (standard HDMI, mainly used for TVs, projectors and laptops), Type C (mini HDMI, commonly found on tablets and some laptops), and Type D (micro HDMI, for tablets and smartphones). Connectors: what a difference a pin makes The main focus was computer displays, graphics cards and professional IT equipment, so more data centered markets. This is why you will find HDMI ports most commonly on appliances like television sets, gaming consoles, projectors and home computers.Ī few years later (2006), another large consortium of PC and chip manufacturers worked to create DisplayPort (DP), a follow-up of the older VGA and DVI standards. These are large corporations that primarily target purely image driven applications. ![]() HDMI (short for High-Definition Multimedia Interface) was introduced in 2003 by a consortium of (mainly) display manufacturers, including Sony, Philips, Panasonic, and Toshiba. While both HDMI and DisplayPort have the same objective, they were in fact conceived under different constellations. So is there also a format war between DisplayPort and HDMI going on? Not exactly. More recently, there was the battle between Blu-ray and HD DVD. For the youngsters amongst us, VHS finally won mainly because of its lower cost and support by the adult movie industry. Just think about the video recorder standards war in the early 1980s between Video 2000, VHS and Betamax. There are a lot of examples in technology history of multiple competing standards that were on the market simultaneously. But what is – apart from the clearly distinct connectors – the difference between DisplayPort and HDMI? After all they were designed to do the same thing, right? In this article we try to give you some advice… DisplayPort and HDMI are two distinct standards for transmitting video and audio from a player to a display.
