HDMI and DisplayPort are both used for high-resolution displays, but DisplayPort typically supports higher resolutions and refresh rates than HDMI. Therefore, DisplayPort is the better choice for the best video quality on high-resolution monitors. VGA and DVI are older standards that do not support as high resolutions as HDMI or DisplayPort. Mini DisplayPort is similar to DisplayPort, but it is not as widely compatible as the full-sized DisplayPort connector.
