Goodbye DVI, VGA, welcome DisplayPort

The Electronic Imaging Standards Association (VESA) yesterday (April 4) approved DisplayPort 1.1 to become the new communication standard for display devices such as flat screens, projectors, PCs and electronic devices. consumption.

This means we will have to say goodbye to the widely used communication standard today: DVI and VGA. However, it will take several years for this to happen.

The most striking feature of DisplayPort 1.1 is the ability to support High Bandwidth Digital Content Protection (HDCP) 1.3. This is the communication standard needed to support high-quality content Blu-ray and HD-DVD which allows anti-theft of digital image content.

DisplayPort is designed to replace the currently used LVDS, DVI and VGA communication standards. Many manufacturers have announced that they will quickly adopt the new standard for a very simple reason that DisplayPort only needs a single digital interface for the connection to display in and out. In other words, DisplayPort can transfer images directly from any source to any LCD monitor.

Another outstanding feature of DisplayPort DVI and VGA is a compact connection port such as USB port, bidirectional connection, audio support, high data transfer rate of up to 10.8Gbps and small architecture design. Simple compact allows for more new display features to be integrated.

DisplayPort 1.1 will be an open and free standard. VESA is completing the standard technical instruction set.
