The DVI digital interface can be used to transmit the computer signal directly to the display, with almost no signal loss in between. It is directly the transmission of digital signals, and there is no interconversion link between analog and digital signals. The advantage of DVI is mainly reflected in the fast signal transmission speed.
The picture display is highly clear.
VGA is mainly used for old-fashioned computer output. The VGA outputs and transmits analog signals. Everyone knows that the reunion hole of the computer graphics card generates a digital signal, and the display also uses a digital signal.
DVI interface specifications
When transmitting digital signals, the DVI interface is divided into single link and dual link. The transmission rate of a single-connected DVI interface is only half that of a dual-connection, which is 165MHz s, and the maximum resolution and refresh rate can only support up to 1920x1200, 60Hz.
As for the dual-connected DVI interface, it supports up to 2560x1600, 60Hz mode, and can also support 1920x1080, 120Hz mode. In order to achieve 3D effect, the LCD must have a refresh rate of 120Hz, so in the 3D solution, if you use DVI, you must use the DVI cable of the dual-connected DVI interface. In general, if it is a resolution within 1920x1200, the image quality output of single and double connections is the same.

Anonymous users2024-02-06There are obvious differences between DVI and VGA interfaces in terms of appearance, transmission signal, use, function performance and color performance.
1.Appearance: The appearance of the VGA interface is 15 pins, while the appearance of the DVI interface is a 24-pin connector. However, appearance alone cannot accurately identify the two interfaces, because the difference in appearance is not enough to distinguish between the two interfaces.
2.Transmission signal: The VGA interface transmits analog signals, while the DVI interface transmits digital signals. This means that the signal is easily lost when using the VGA interface, and the display may be blurred due to distortion sheds, while the signal on the DVI interface is not.
3.Usage: In the older generation of display devices, VGA is an analog signal with good compatibility. However, now good LCD monitors or projections support DVI interfaces, and DVI interfaces have become popular.
4.Function: From the functional point of view, the DVI interface is stronger.
The computer's display signal is a digital signal, so if the LCD also supports DVI, it can achieve lossless display. Still, signal loss is unavoidable when using a VGA interface, but the loss of posture is much less than that of DVI.
5.Color performance: Although there are differences in color performance, which is better depends on what is displayed and how the viewer perceives it.
In general, there are many differences between DVI and VGA interfaces, and the choice of interface depends on the use case and personal preference.
