HDMI is a standard from the HDMI Forum. This non-profit organization develops and maintains the standard, manages its testing and certification for interoperability, and promotes it. More than 80 member companies support the Forum. The standard became available in 2003 and has been continuously updated. The current version is 1.4. It complies with the EIA/CEA-861 standards that define the video formats and methods of transmission for both compressed and uncompressed video and audio.
The consumer electronics industry almost universally adopted HDMI as the “the” video transmission standard. It appears in HDTV sets, DVD/Blu-ray players, cable and satellite set-top boxes, AV receivers, digital games, digital cameras, video projectors, and some video monitors. It is even available on some tablets and smart phones.
HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transferring, uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards

DisplayPort is a computer connection format. There is only one television with DisplayPort , and don’t expect it to see much further adoption on the TV side. It’s capable of 3,840×2,160-pixel resolution at 60fps, if you have at least DisplayPort 1.2 and the Multi-Stream Transport feature. If you’re looking to connect a computer to a monitor, there’s no reason not to use DisplayPort. The cables are roughly the same price as HDMI.
DisplayPort can also carry audio.
The video signal over DVI is basically the same as HDMI. The maximum resolution potential depends on the equipment, though. Some cables and hardware (called single-link) can only do 1,920×1,200, while others (dual-link) can do more.
DVI generally doesn’t do audio (it varies). So if you’re using a TV, use HDMI. Since computer monitors don’t usually have speakers, this isn’t an issue.
