Each of the three major video connectors has problems that limit their use with future computer displays. Even though they have addressed some of the issues, some still remain. Let's take a look at each of the formats and the problems that they have:
DVI
Single DVI limited to 1920x1200 resolution with 24-bit color
Dual-link DVI limited to 2560x1600 resolution with 24-bit color
Heavy cabling requires connector to be screwed into card/display
No audio support
HDMI
Version 2.0 supports up to 4K Resolutions but fairly uncommon still
Version 1.3 supports up to 2560x1600 resolution with audio stream
Version 1.1 supports up to 1920x1200 resolution with audio stream
Category 1 cables limited to 5 meters in length
DisplayPort Basics
DisplayPort was developed among the members of the Video Electronics Standards Association.
This is a group of roughly 170 companies that develops and decides standards to be used with computer displays. This is not the group that developed the HDMI standards. Because of the greater demands of computers and the IT industry, the VESA group developed DisplayPort.
In terms of physical cabling, the DisplayPort cables and connectors look very similar to the USB or HDMI cables that are used today on most computers.
