8K Detachable Pure Fiber Optic Armored HDMI 2.1 Cable 33FT, Ultra High Speed 48Gbps, Support 8K@60Hz 4K@120Hz, Dynamic HDR, eARC, Compatible with PS5/Xbox/Blu-ray/TV/Monitor/Projector

Works fully with a PC, signal output from a RTX 4090 at 4K 120Hz 10 or 12bit RGB, including HDR and Dolby Atmos audio. The fiber optic cable and the lack of a fat HDMI plug is definitely easier to run long distances than a typical HDMI cable.Note: Not sure if isolated to my setup with a S90D OLED, but the CEC issue with Samsung TV's is present, whereby when plugging in the HDMI dongle will interfere with CEC volume control on/off control of other devices such as HDMI eARC soundbar. When you unplug the HDMI dongle, the other devices kick back in for those functions. Dealing with it by putting the microUSB power plug at the display end behind a smart plug, and turning it off when I don't use my PC

This thing worked great. I have my computer about 85-90’ away from my office (basement to 2nd floor) because it outputs too much heat—makes the office too toasty. Used to use HMDI over Ethernet extenders, but their durability was inconsistent. I tried another 100’ HDMI cable that claimed to be also fiber optic, but it wouldn’t even do 2K reliably. I think an HDMI run that long simply needs to be powered, which the other cable wasn’t.This RUIPRO cable seems to be the real deal—I get 4K at 60 Hz with ease. Pulls through conduit pretty easy too. Worth all the money, at least so far.I will note that it does seem to have a bit of a handshaking issue with my monitor (Samsung U32J590UQN) where I have to cycle inputs after the computer wakes up from sleep.

This cable/adapter, as promised, can do 4k 120Hz video no problems. Devices see it as just a normal cable, no different than a copper one. The MPO fiber cable is nice and thin, very easy to run and unobtrusive. The converters themselves are larger than a normal HDMI end, but not all that big. We've had no issues getting them to fit where they need to go.As noted, it did require USB power on the display end to function, it comes with the cables you need and it doesn't need much so you can power it from a USB port on your display/receiver, or a small AC to USB adapter. I haven't needed power on the source end on any of the devices we've tried.

This is the single best idea for long cables ever and it is executed well!It is modular and can be extended as you wish, no proprietary cable connections ,etc.It works perfectly as advertised. I am having the full 48Gbps from PC to monitor over 100ft.I love the idea that I can bring my own fiber cable and use them as my application needs it.@RUIPRO: please if you read this, make DisplayPort and Thunderbolt cables the same way. PLEASE!!And the best would be if you would offer "only kits" that does not have the fiber cable only the adapters. That would be amazing!Either way thank you for thinking and releasing this product. Finally a perfect solution for my long distance data cable needs. (HDMI2.1 checked, now please make the same for DP2 and TB5/USB4)

The dongle and fiber cable together work out to over 3 inches long, which means they won't fit behind most TVs. Despite being powered, the signal they produce is so weak that ANY cable or adapter in line will cause it to have intermittent signal at 4K60, with continuous drops to black screen. I've ensured that the cables and adapters I've tried are HDMI 2.1 and well rated and I've tried three different ones from different manufacturers and different form factors, but all of them eventually run into the same intermittent black screen problem. With the screen taken off the wall so the cable can directly connect it works fine.If you don't need 4K60 or you have plenty of room for a massive connector to stick out, then you may not run into this issue. If both of those are true then it will be a huge waste of time and money. That is not acceptable from an expensive, powered HDMI cable.

Why did you pick this product vs others?:This gave me 4k, 60hz, HDR, dolby vision, Atmos over 50 feet no problem

Great quality cable, signals been good and great for distance

i purchased a competitor cable from Fiber Command for more than double the price. Unfortunately that cable didn't support CEC nor supported eARC only ARC. I stumbled upon this one after an ad recommendation and this cable is indistinguishable from a regular HDMI in terms of functionality. I am using it to run about 30 Feet to my movie room projector back to a Denon receiver in another closet. Support is also great and responds quickly to inquiries regarding functionality. Just one thing to note is you need both ends powered in order to use CEC functionality. Also make sure if you don't use the included MPO cable and need to purchase a Standard MPO cable, that its Type-A ( Straight Through ). I tried to re-use the in wall cable from another vendor and found out the hard way. Otherwise good quality and i highly recommended for the price. Only small wish is that the power port is USB-C instead of mini but just a nitpick
