DVI
The DVI interface is relatively large in terms of interfaces such as VGA, HDMI, and DP, and is the most important interface type of the current LED splicing/processor.
Its greatest advantage is its fast speed and clear picture. The DVI transmission is a digital signal, which does not require a digital-analogue-digital cumbersome conversion process. This greatly saves time and speeds up the elimination of smearing and other phenomena. This makes DVI more fine-grained than high-resolution VGA, and is less susceptible to signal interference.
HDMI
The HDMI high-definition multimedia interface organization officially released the HDMI 1.0 version standard in December 2002, marking that HDMI technology has officially entered the stage of history.
HDMI can not only meet the 1080P resolution, but also supports digital audio formats. Compared with DVI and VGA, the HDMI interface has a smaller size, but because its port is smaller and there is no reinforcement device, it is easier to loosen. Therefore, the application in the LED splicing/processor is currently not as extensive as DVI and VGA.
