Sadly the cable starts to flicker at 4k 120hz output from my pc

Comprei um cabo hdmi de 10 mt. Só durou 6 meses, durante um filme ele deixou de funcionar. O problema é que este cabo não tem garantia, não vale a pena. Acabei por comprar outro numa loja física (wortem) onde me deram 3 anos de garantia.

J'ai acheter ces câbles hdmi optique 10M de long j'avais le câble hmi classique compatible 8k avant en 7,50M alors le résultat est est tout bonnement stupéfiant sur vidéoprojecteur 4k bien meilleur colorimétrie,déradé couleur plus large et bien plus naturel,contrats légerement plus élevé une telle difference de qualité visuel avec juste le remplacement du cable hmi en optique sincèrement je n'aurais pas cru sans le voir de mes yeux très très satisfait de ces câbles!!remplacement des autres plus court a l'avenir que par ce modèle hdmi

After tearing what little hair I had left trying to get my BenQ projector working with my Denon receiver, this worked perfectly. I needed 8m and this proved to be too much for my older cable (which also turned out to be only 1080p capable, not 4/8k). This cable sorted that.My projector is also a bit unusual in that it has a Google TV dongle integrated into it, so I needed eARC to send audio back to the receiver occasionally. Optical cable are meant to be one-way only, but apparently this is a hybrid cable which has copper wiring for the eARC too. Not everyone realises this is a thing now.
