My old Apple-certified Belkin cable broke due to me moving the TV so I was finding a replacement. This one looked good and it is, indeed, good. It's good even with bandwidth-sensitive AppleTV. It's a big pipe and had no issue with high-bandwidth transmissions. One thing, though, during installation, make sure you read the label on each end of the cable {Source, Display}. The cable is one-directional ONLY, so it needs to be connected correctly or it will not work.

Initially had an issue with flicker, but the manufacturer was incredibly helpful and sent out a replacement the next day, no questions asked. No issues with the replacement. Supports full RGB at 4k 144hz and no hiccups

Broke within few months.

This cable is great, I managed to hook up my pc to the tv on the other side of the room… until it started artifacting and disconnecting after a few minutes of use. So the cable was shot. Instead of returning the cable because that would be out of the way, I heard their customer support was great, so I sent out an email and after responding to their initial response, zero hesitation they sent out a new one and it came the next day. Replacement 100% works. 10/10 cable and customer support. Maybe not so much the first cable. Would order from them again knowing they stand by their warranty

Great product and fast delivery. Would buy again

**Update, although the cable wire turned out to be useless to me in my Denon setup, customer service is top tier. They definitely look out for their customers and for that deserve a high rating! Bought this HDMI cable thinking it was top quality based on description and price however after a month using it, I got sick of the random audio dropouts every time I would watch tv. Had to pay a tech guy to come and check out my setup (Samsung TV to Denon receiver) and quickly mentioned the one directional HDMI cable was my issue with the audio dropouts. I switched over to a regular HDMI and what do you know….no more audio dropouts. Now it’s too late to return so money down the drain.

Updated to 3 stars. Company reached out and offered a full refund. I bought a replacement cable and had similar issues, despite being directly plugged into the receiver and the projector. Right now it shows weak signal but works, same as the old cable. Hopefully it doesn't degrade like the last one. Original: Item worked great for the first month I had it. Within the last few days, the signal seems to have gotten weaker. First it started with display issues on the projector, and I had to downgrade the HDMI port from enhanced to standard. Now every few minutes I get a brief black screen. For the money spend on this cable, didn't expect to have so many issues with it. The most recent development is now I have to reboot my input device to get the image to show. I have the image split to the projector and another monitor, the monitor works fine with no signal issues, just the projector seems to be the issue with this cable. Using the Visionmaster Pro 2 projector

Refuses to work at 4K 120Hz as advertised. It runs at 120Hz at 1080p or 60Hz at 4K. A shorter length likely resolves the issue, but since the title advertises this as a fiber optic cable, it shouldn't have this issue.

Ce cable fonctionne parfaitement. D'une longueur de 15 mètres, l'image est parfaite en 4k. Le cable est assez souple pour être inséré dans des gaines électriques. parfait. je recommande vivement.

Das Kabel macht einen guten Eindruck und wird in einer doch überraschend ansprechenden Verpackung geliefert. Es ist schön dünn und recht flexibel. Ich habe mit diesem Kabel meinen mini mac mit meinem AV Receiver verbunden. 4096x2160 schafft das Kabel nicht ( wird ja auch nicht beworben ), aber UHD ( 3840x2160 ) mit 120HZ funktioniert absolut problemlos. Bild und auch der Ton ( Ordnungsgemäß als Dolby Atmos 7.1 ) werden sauber übertragen. Nun hoffe ich nur, daß das Kabel einige Jahre gut funkrioniert.

Super HDMI, verlegt mit TV Netzkabel in einem Kabelkanal kein Ton Aussetzer mehr, davor hatte flachen HDMI und nur Probleme gehabt wie Ton Aussetzer bei zb. licht an, oder Rollos auf zu fahren.

PC will not boot when this is plugged in. Works fine with the other HDMI cable to the same device.

Parfait
