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.

Displayport cable length limit 4k.

What is the maximum length displayport cable that can handle 3840x2160 60hz. Now i m using one 2 meters cable and two 3 meters cables with two active displayport extenders between them to drive a 2560x1440 monitor at 165hz. Using anything beyond that increases the chances of the risks mentioned previously. I ll add that these are the highest quality most expensive cables i could find.

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. Ymmv with cheaper cables. 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.

I tried huge numbers of cables and different. 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. It would seem that the answer is only a mere 10 feet but i can t actually find this on the dp site or in any documentation. All standard displayport cables support rbr hbr high bit rate and hbr2 high bit rate 2 which can support 4k at 60hz.

This decision limited confusion in the market place but set the maximum limit for a certified displayport cable at 5 metres. 2 0 m connector number. I realize that it takes some juice to power 4k 60hz but i was really hoping to find a cable that was at least 15 feet long. I discovered that the maximum length is about 15 feet give or take a couple feet based on the quality of the cable.
