Displayport Cable Length Limit

The displayport standard does not specify any maximum length for cables though the displayport 1 2 standard does set a minimum requirement that all cables up to 2 meters in length must support hbr2 speeds 21 6 gbit s and all cables of any length must support rbr speeds 6 48 gbit s.

Displayport cable length limit.

Maximum length of displayport cable for optimal performance when using display port cables the length of the cable can greatly impact display quality and create data loss. For example a standalone hdmi cable can go up to 65 while a standard displayport cable can go up to 15. When using cables with two different ends the distance limit will be subject to whichever type of connector has the shorter maximum distance. While displayport offers support for cables of varying lengths the maximum cable length that dell recommends for optimal performance is 1 8 meters around 6 feet.

According to dell the maximum recommended cable length to ensure optimal performance is 1 8 meters 6 feet. If you can come up with a superior manufacturing technique or a design with better signal transmission properties or a manufacturing process with better tolerances then you can make a. A standard displayport cable including the so call displayport 1 1 cables will work for any displayport configuration including the new capabilities enabled by displayport 1 2 including 4k and multi stream capabilities. It just depends on manufacturing quality and tolerances.

For example a standalone hdmi cable can go up to 65 while a standard displayport cable can go up to 15. Maximum cable length isn t something that s defined in the standard if that s what you re hoping for. When using cables with two different ends the distance limit will be subject to whichever type of connector has the shorter maximum distance. Therefore an hdmi to displayport cable will be stuck at 15 for its maximum length.

This decision limited confusion in the market place but set the maximum limit for a certified displayport cable at 5 metres. Therefore an hdmi to displayport cable will be stuck at 15 for its maximum length.
