Summary of DVI and HDMI
DVI was created in 1999 by Digital Display Working Group. DVI can only transmit video and was designed to replace VGA connectors. DVI connections are typically found on older monitors. Adapters can be purchased to convert DVI to HDMI. The price of a quality DVI cable that measures 6 feet or less is usually under $10.
DVI connectors have a much larger footprint than HDMI connectors. They have square connectors with two screws for security. The front side of the connector usually consists of 24 primary pins in a three-row matrix. To the right of these pins is four additional pins. There are seven different types of DVI ports. These ports include DVI-A, DVI-D, and a variety of DVI-I. The ports are not interchangeable. Some older computers did have mini and micro DVI connectors. These are no longer produced. Below are some of the key DVI specifications:
- Max data rate of 9.9 Gbit/sec.
- Resolutions of up to 3840×2400 at 30Hz or 2560×1600 at 60Hz.
- Supported resolutions exceed most users needs.
- Can support refresh rates of up to 144Hz at much lower resolutions than HDMI.
HDMI cables were created in 2002 by Hitachi, Panasonic, Philips, Silicon Image, Thomson, and Toshiba. They were designed to transmit high-quality audio and video. HDMI was intended to replace DVI and older video and audio cables. HDMI is ideal for gaming and other high-end computing needs. The price of a quality HDMI cable that measures 6 feet or less is usually under $10.
HDMI has a much smaller footprint and looks very different than DVI connectors. HDMI connectors have a slim rectangular design with 19 pins in the front. They do not use screws for security. HDMI is the common standard for computing, gaming, and television needs. While HDMI is still very common, DisplayPort connections are gaining popularity. Mico and mini HDMI ports are also available on a wide range of compact devices such as tablets and smartphones. HDMI is supported by significantly more devices than DVI. Adapters are available to convert HDMI to DVI. These adapters typically only transmit video signals. Below are some key HDMI specifications:
- Max data rate of 42.6 Gbit/sec.
- Supports resolutions of up to 4k at 144 Hz or 8k at 120 Hz.
- Supports HDR video output.
- Supports 32 audio channels to include DTS HD and Dolby True HD.
