DVI cables are most frequently used for connection between PC and flat screen or projector. By using a digital DVI monitor cable, a high digital image quality and resolution is achieved, as conversions to analogue signals and back again are entirely avoided. This provides a sharp image, high contrast, more depth and super rich colours.
The DVI-I connectors are compatible with both analogue (VGA/XGA) and digital signals (DVI-D, HDMI). DVI-D connectors can only be used for pure DVI-D cables, but are still compatible with HDMI. DVI-D is also compatible with DisplayPort.
