I reached out to the company becuase my cable seemed defective after 5 months; it would cause my screen to flicker or cut off the display intermittently. I wrote the company that I had since purchased a new cable which did not have these problems and inquired about their refund policy. I was contacted by PC Microstore and after upon providing them with this information and my Amazon order number, I was promptly refunded the cost of the cable to my Amazon account. Based on this, I would not hesitate to buy a GearIT item as they will work to ensure customer satisfaction.I bought this to drive a UHD monitor at 60 Hz from my XPS 17 laptop and it works. Cable seems well made. No problems.I love this cable I have used them many times to add a second monitor to iMac's simple plug and play.You can't beat the price and the quality is as good as the Apple version maybe even a little better.Quick delivery, sturdy construction, and the perfect length to fit my needs.Does what it says. Now I'm able to run my monitor at 144hz, thanksCon este cable mejoró mucho la transmisión de imagen de la MacBook Pro 2019 de 16 pulgadas a un monitor HP 4K de 27 pulgadas
