What is the difference between the DVI interface and the D-sub interface of a computer monitor?
At present, the liquid crystal display interface mainly has D-Sub (VGA) and DVI two kinds. The D-Sub interface appeared mainly in the low-end products, need to go through a / D conversion, analog / digital conversion two conversion signal, while the DVI interface is the digital signal transmission without loss, mainly in high end products.Since the DVI interface is completely digital transmission, the resulting picture will never appear to be "virtual". The D-Sub interface, as it is modeled, has this unstable factor in its own right, so it will inevitably cause some trouble for our use.When the liquid crystal in the long use of D-Sub interface, there will be fuzzy effect, the need to use the Auto key to re proofread in order to restore normal results (but the actual use of little impact, I am using). But the DVI interface LCD will never appear a similar situation, after a long time use, the display is still excellent.

The DVI is a digital interface that provides digital signalsThe D-sub, that is, the VGA interface, provides analog signals
It's better to use the DVI interface. The picture is better than using the D-sub interface. I'm also using BenQ's FP92W monitor and using the DVI interface
