DisplayPort DisplayPort gains active cable support

You know those unused DisplayPorts on your graphics card? Well, you're most likely not going to get much more use of them, at least not yet, but when we finally start getting more DisplayPort enabled monitors, the good news is that VESA has announced an extension to the DisplayPort 1.2 specifications that supports active cables which to you and me means longer cables.

You know those unused DisplayPorts on your graphics card? Well, you're most likely not going to get much more use of them, at least not yet, but when we finally start getting more DisplayPort enabled monitors, the good news is that VESA has announced an extension to the DisplayPort 1.2 specifications that supports active cables which to you and me means longer cables.

Now most of us don't need more than a 2m or usually shorter cable to connect our monitor to our PC, but thanks to the extension to the DisplayPort 1.2 specification we can now look forward to support for up to 33 meter long DisplayPort cables. So what is an active cable you ask?

Well, an active cable is usually powered and is fitted with additional chips; in this case a signal booster and equalizer that help prevent attenuation of the DisplayPort signal. Apparently the active cables will also allow for thinner wire gauges to be used as well, something which in our opinion might not be such a good idea, as it's possible that interference might creep in.

Of course, this is only an addition to the specification and as to exactly what kind of products we'll see in the market is a different matter. We can see this being a handy addition in many niche markets where the extra bandwidth available in the DisplayPort AUX channel could be used for both networking and USB signalling, thus allowing for a single cable to transport everything needed for say a trading floor setup which today tend to have to rely on expensive fibre optic solutions. Now where are all the DisplayPort monitors..?
