Displayport Cable Length Limit

Because displayport was so ahead of its time in terms of bandwidth and resolution capability when it was launched strict limits were set on what cable lengths could be certified.

Displayport cable length limit.

According to dell the maximum recommended cable length to ensure optimal performance is 1 8 meters 6 feet. 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. All standard displayport cables support rbr hbr high bit rate and hbr2 high bit rate 2 which can support 4k at 60hz.

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. 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. When using cables with two different ends the distance limit will be subject to whichever type of connector has the shorter maximum distance. This decision limited confusion in the market place but set the maximum limit for a certified displayport cable at 5 metres.

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. 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. For example a standalone hdmi cable can go up to 65 while a standard displayport cable can go up to 15.

Using anything beyond that increases the chances of the risks mentioned previously. 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.
