DisplayPort 1.2 Gets Active Cable Support
The Video Electronics Standards Association (VESA) has announced an extension of its DisplayPort 1.2 standard to support active cables. Such active cables can run up to five times the length of passive cables.
In a press release, VESA outlines the advantages of DisplayPort active cables:
Active cables boost and equalize the attenuated DisplayPort signal, allowing cables to reach unprecedented lengths and enabling the use of thinner wire gauges when compared to normal passive cables. The configurations of home theaters and digital signage installations have historically been limited by the display cables connecting the devices. For high-definition display placement, the limits imposed by passive cables meant that short distances were needed to avoid compromised image quality. With the addition of active cables to the DisplayPort standard, cables lengths of more than 100 feet (33 meters) are possible, greatly increasing configuration flexibility in cable routing and equipment placement.
To identify the new cable, VESA has also developed a new DisplayPort active cable logo.
