15' DisplayPort Cable

There is a lot of confusion regarding display port cables and what to select for your purpose. Prior to purchasing, I contacted Star Tech for clarification on a 15ft version of this cable and whether it would work at 1080p at 144hz for a gaming monitor and got this response - "The DISPLPORT15L 15ft DisplayPort cable is certainly compliant with DisplayPort 1.2 HBR2 specifications with bandwidth up to 21.6Gbps. I do not suspect there will be any issues with running the DISPLPORT15L with a 1920x1080 monitor at 144Hz. The bandwidth required will be well below the 21.6Gbps of which the cable is capable. There will be no flicker with a 1920x1080@144Hz display due to the DISPLPORT15L." After receiving the cable, I have found that the cable works flawlessly with no flicker or drop off while gaming at the highest settings. I am very satisfied with this cable for my purposes and if you are looking at similar specs, then I would suggest this cable over the other brands currently available, as this is the only one I could locate after several hours of scanning forums, that is capable of 21.6Gbps.

For my display port 1.2, it worked and in my short use I did not come across the problems that other people are complaining about in reviews. Intermittently there may have been a lag, but too short to be noticeable. It does not have the fine quality of Apple but it worked.

High-quality! Nice thick cable, which may be an issue if you need a thinner cable. I bought the 15ft one and it supports 2560*1440p at 144hz! Took forever to find a cable that'd could do that and I'm stoked it does!

As stated in the headline, this works perfectly with a high refresh rate monitor! Freesync/Gsync also is applied by default when using this cable! Did not notice any stuttering! Everything is buttery smooth and picture quality is perfect! On a side note, make sure to cap your FPS limit to that of your monitor if your want to take advantage of freesync! Very happy and relieved that this works! :)

This cable is advertised for 21.6 Gbps. I tried it first at 4k and 30 Hz which only requires 6.18 Gbps. I get a lot of flicker and a lot of desyncs. I then tried it at 60 Hz that requires 12.54 Ghz which is why I purchased the cable in the first place. All I get is a blank screen, it can't even sync up at all. I tried two cables, and I tried to reverse the cable so that the opposite ends were plugged in case of bad ground termination. There was no way I could get the cable to work at 60 Hz which is well within the advertised specification. I'll be returning the 3 cables I got as soon at Amazon's return form works for me.
