What is the use of the DVI interface of the monitor?

Subdivided into DVI-D and DVI-i, DVI-D is a pure digital interface, the best choice for large-screen LCD. DVI-I supports digital and backward compatible analog signal output, and our common DVI to D-Sub adapter must be used on DVI-I to achieve conversion.

D-sub--D type interface, commonly known as VGA interface, analog signal output interface.

At present, there are two main types of LCD interfaces: D-Sub (VGA) and DVI. Among them, the D-Sub interface mainly appears on low-end products, which needs to be converted twice through digital-to-analog conversion and analog-to-digital conversion, while the DVI interface is an all-digital loss-free transmission signal, which mainly appears on high-end and high-end products.

Because the DVI interface is completely digital, the final picture will never appear to be "blurred". The D-Sub interface, because it is an analog method, has this instability factor, so it will inevitably bring some trouble to us.

When the liquid crystal is used for a long time on the D-sub interface, the effect will be blurred, and it needs to be recalibrated with the auto key to restore the normal effect. However, the LCD display with DVI interface will never have a similar situation, and the display effect is still excellent after long-term use. In the case of **comparable, we should consider more liquid crystals with DVI interface.

The difference between the VGA, HDMI, and DVI interfaces of the monitor:

graphics adapter) interface is also the common name of D-sub interface, which is an interface that uses analog signal transmission; VGA first refers to the display mode of 640x480, and the application of VGA technology is mainly based on VGA graphics cards for computers, notebooks and other devices;

The interface has the advantages of high resolution, fast display rate, rich color, etc., and has been widely used in the field of color display, does not support hot swapping, does not support audio transmission;

The interface is more delicate in high resolution and is not easy to be interfered with by signals, and the DVI interface is divided into two modes: single link and dual link when transmitting digital signals. The transmission rate of a single-connected DVI interface is only half of that of a dual-connection, which is 165MHz S, and the maximum resolution and refresh rate can only support up to 1920x1200, 60Hz;
