Can you run full HD through a vga connection?

VGA can certainly support HD standards. VGA is a hardware standard for display interfaces and supports numerous resolutions including 720p, 1080i and 1080p. In fact, VGA ports often support even higher resolutions. The practical use of VGA for HD display has some limitations due to commercial restrictions.

Commercial HD content delivered via disc, cable or satellite is exclusively delivered to a display using HDMI. This is a digital interface and supports HDCP, a protection system that encodes the signal to prevent copying HD material. Commercial HD players and receivers do not output HD signals through a VGA port as HDCP cannot be implemented on VGA ports.


Non commercial HD content and some downloaded content can make good use of VGA displays but generally, HD material will demand HDMI rather than VGA. It is worth noting that DVI outputs on computers are compatible with HDMI but do not support HDCP, Therefore, the use of DVI is limited in a similar way to VGA.
