Displayport cable length limit.

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. All standard displayport cables support rbr hbr high bit rate and hbr2 high bit rate 2 which can support 4k at 60hz. Using anything beyond that increases the chances of the risks mentioned previously.

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. According to dell the maximum recommended cable length to ensure optimal performance is 1 8 meters 6 feet. 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.

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. Maximum cable length isn t something that s defined in the standard if that s what you re hoping for. It just depends on manufacturing quality and tolerances. Therefore an hdmi to displayport cable will be stuck at 15 for its maximum length.

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. 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.
