Unfortunately, you can buy a 4K-compatible DisplayPort cable "known" in any of the major electronics stores near !? Hab then bought a reasonably priced and only annoyed me !! In the 4k resolution image extremely noisy! So it was no use! Did then bought the cable described above and am very satisfied! It is quite felxibel and is super shielded! It is located right next to the power and USB cables. The picture is crystal clear and disturbing effects do not occur. I did not think that it is so hard to find a good cable! But who buys cheap, pay just twice!
