There are many types of monitor interfaces, and currently the more popular interface types are DP, HDMI, VGA, and DVI. The shapes of these interfaces are not the same. When we are purchasing a host, we must consider whether the host’s graphics card interface matches the display interface. For example, when your graphics card interface is HDMI+DP, and the display only supports VGA interface, you can only choose to change one of the devices or purchase another interface.
DVI is a high-definition interface, but it does not support audio. Therefore, the DVI video cable only transmits picture graphics signals, not audio signals. Since it was originally designed for the PC, it has poor compatibility with TVs and only supports 8bit RGB signal transmission. And the interface volume is relatively large. At present, the better DVI interface can transmit 2K images, but it is basically the limit.
At present, the more popular HDMI can transmit both high-definition graphics image signals and audio signals. And the anti-interference is stronger. At present, the highest HDMI2.1 standard supports 8k 60Hz and 4k 120Hz, and the resolution can reach up to 10K. It also supports high dynamic range HDR and can increase the bandwidth to 48Gbps.
Most displays now have DVI+HDMI dual interfaces, which can be adapted to two transmission methods. But in fact, the full application of HDMI interface is inevitable. For individual users, the traditional D-interface display has fallen behind. If you need to buy a monitor, you should avoid this D port and choose HDMI or higher-definition DP port.
