ATZEBE DisplayPort Cable -20m, Fibre Optic DisplayPort Cable 1.4 Support 8K@60Hz, 4K@144Hz, HDR, 3D, High Speed 32.4 Gbps, HBR3, HDCP 2.2

I moved my PC to the living room last year and so bought a Amazon Basics 10m HDMI cable as I had a rather old 24" 1080p 60hz monitor at the time, which did not have DisplayPort. A few months ago I upgraded to a 32" 1440p 144hz Freesync monitor. The HDMI cable was unfortunately only able to cope with 100hz at 1440p, and as I am running an nvidia card and HDMI, this also meant that I could not enable Freesync.Having looked around for long length DisplayPort cables I eventually bought this. I was a bit hesitant as, well, compared to anything else that I could find this cable is actually quite cheap, and I tend to shy away from cheap stuff as it's generally cheap for a reason.However, it arrived today and I dragged it across the house to test it and make sure it worked before clambering around in the loft, and sure enough it works flawlessly! I'm no cable expert but it actually looks a quality product as well.It arrived coiled up in a relatively small box, with a couple of reusable velcro ties. The plug ends are a nicely polished metal (I think they claim zinc?) and are unexpectedly weighty - they get slightly warm in use so I assume this probably also acts as heatsinking for the electronics. The cable itself is very thin and flexible. It did want to retain its coiled up shape but I doubt this is a problem and it would stretch out straight if needed. I only actually need just over 10m of it, so I handled it very delicately and just let it lay however it wanted to lay. It is much thinner and more flexible than the chunky HDMI cable that it is replacing - probably no thicker than your average USB charging cable.Only time will tell if it actually lasts, but I'm feeling confident after the initial impressions!

The DP cable is hooked up to a 1440p 144mhz Gsync screen up stairs I got the 20m version, cheapest optical DP I could find and it works great

For the price you’d expect a reliable cable, but after 3 months it’s already stopped working. Shocking at this price point.
