Previously, analogue VGA standards were more prevalent in the market, but now non-VGA specifications, like DVI and HDMI, have gained more popularity. They provide high- resolution, high performance video from the broadcast signal. Today’s PCIe video card support either DVI, HDMI, Display Port, or Mini Display port outputs.
Display ports and connectors are:
- HDMI: Audio and video signal, best for TV to PC connections.
- DVI: Video only, perfect for older systems or for 144Hz at 1080p.
- Display Port (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K.
- VGA: Old, legacy video connector. Only to be used when nothing else available.
- USB Type-C: Newest audio, video, data and power connector. The best laptop connection. 5 Reasons Why You Need a USB-C Docking Station
- AV: AV input is a common label on a connector to receive (AV) audio/visual signals from electronic equipment that generates AV signals (AV output).
- NDI: Network Device Interface – Format that allows you to send audio and video via Ethernet network
- SDI: SDI Serial Digital Interface is a professional video signal that is preferred in production environments because of its longer range (up to 300 feet) and reliability, since it’s typically sent along BNC Cabling that has specialized connectors on each end to lock into the devices they connect to.
- BNC: The BNC connector is used in a coaxial cable. It has two bayonet lugs on the female connector. The male connector is fully connected to the female connecter only when the coupling nut is quarter turned. Normally, the BNC connector is used for composite video on commercial video on commercial video device.
