HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transmitting 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 was first introduced in 2002.
- The HDMI 1.0 specification was released in 2002.
- The HDMI 2.0 specification was released in 2013.
- The current HDMI 2.1 specification was released in 2017.
DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). It is primarily used to connect a video source to a display device such as a computer monitor, although it can also be used to carry audio, USB, and other forms of data.
Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). It is designed to provide digital video signals between a computer or other video source and a display device such as a computer monitor or television.
These cables are used to connect devices with HDMI outputs to devices with HDMI inputs, such as computers, monitors, televisions, and projectors. They come in various lengths and types, including standard HDMI, high-speed HDMI, and HDMI with Ethernet.
These adapters are used to convert HDMI to other types of video or audio interfaces, such as DisplayPort, DVI, VGA, or RCA. They are useful in situations where the two devices being connected have different output or input options.
These devices allow multiple HDMI sources to share a single HDMI input on a display device. They can be manual or automatic, and some models also support 4K resolution and/or HDCP 2.2 encryption.
HDMI stands for High-Definition Multimedia Interface.
HDMI 2.0 supports resolutions up to 4K at 60Hz, while HDMI 2.1 supports resolutions up to 10K at 120Hz. However, the actual maximum resolution and frame rate depend on the capabilities of the source device, the cable quality, and the receiving device.
Standard HDMI cables can support resolutions up to 1080p and data rates up to 2.25 Gbps, while high-speed HDMI cables can support resolutions up to 4K and data rates up to 18 Gbps. High-speed HDMI cables are also compatible with Ethernet and 3D content.
No, not all HDMI cables support 4K resolution. To support 4K, a cable must be classified as high-speed HDMI and be able to handle data rates up to 18 Gbps.
Yes, HDMI can carry both audio and video signals simultaneously, eliminating the need for separate audio cables.
