If the device has a DVI interface and a VGA interface, what interface should I choose? DVI cable or VGA cable? We know that the VGA interface transmits analog signals, while the DVI interface generally transmits digital signals. Is the digital signal high-definition? In fact, this is not the case. Whether the displayed image is high-definition depends to a large extent on the physical resolution of the display device and whether the video or picture being played is high-definition, not related to the difference between digital signals and analog signals.
Whether the displayed picture is high-definition depends to a large extent on the physical resolution of the display device and whether the video or picture being played is high-definition, and is not related to the difference between digital signals and analog signals. Although the VGA interface transmits analog signals, the VGA mode can support 2560*1600 resolution, which is already higher than HD. It is not possible to compare the differences between the two.
For the device with DVI interface and VGA interface, choose VGA cable or DVI cable? In the case of low device resolution, it is best to use a VGA cable, in which case the VGA cable can meet all display requirements. If the signal input source of the display device is a digital signal, the DVI cable is used, and the dual channel VGA cable can support some 3D display devices, and the dual channel DVI cable can support higher resolution signal transmission. Whether it is VGA cable or DVI cable, it has its own use, so we should choose according to our own needs, and can not blindly devalue certain cables.
