1. At present, there are two LCD interfaces:: D interface (VGA) and DVI interface. Among them, D-Sub interface mainly appears in low-end products, which needs two times of analog-to-digital conversion and analog-to-digital conversion, while DVI interface is an all-digital lossless transmission signal, which mainly appears in high-end products.

2.DVI interface is completely digital transmission mode, so the final picture will never appear that kind of "blur". Because the D-Sub interface is analog and has this unstable factor, it will inevitably bring some troubles to our use.

3. If you use D-Sub interface for a long time, the effect will be blurred, and you need to use Auto key to proofread again to restore the normal effect. The LCD with DVI interface will never have a similar situation, and the display effect will still be excellent after long-term use.
