Great to extend length of XR Glasses cable for couch gaming!
Size: 8K Video for monitor extension cable 10FT
I purchased this cable to use with XR glasses. I wanted to be able to plug one side into the 'HDMI to USB Type-C Video' adapter on my PS5, and still be able to reach my couch about 10ft away from the PS5 and TV. This worked great! The Video and audio works perfectly and I can now play my PS5 through the glasses while my wife is using the TV! ... show more

8K Faraway!
Size: 8K Video for monitor extension cable 10FT
Review Image by JM
This is a high quality and specialized USB-C extension cable. It operates on the latest USB-C 4.0 protocol and is capable of carrying video signals up to 8K resolution. Be advised that, as this is the 10 ft variant, it is operating at near maximum range so, if you want (or need) to take advantage of that full 8K capability, your source USB-C cable can only be up to a quarter meter or 0.8 ft in length and must also be 8K capable. I don’t have any 8K monitors but I found the cable more than capable of sending a crisp signal and sufficient operational power from my mini-pc to my 3K work monitor when coupled with a 3 ft, video capable, male-to-male source cable. The cable is capable of simultaneous data, video and charging functions and would thus make a good permanent installation in a USB-C hub type arrangement; the kind of which we are seeing more and more of and as I, myself, have recently adopted. This obviates the need to have your monitor so close to the source signal. The cable also has a built-in chip to monitor and regulate charging speeds appropriate to the connected devices. The braided construction seems solid and I had no problem in getting the cable to work in any of the environments I attempted to use it in. Highly recommended. ... show more

Solid wire, line is also very thick, the interface is normal, read and write speed is fast
Size: 8K Video for monitor extension cable 10FT
The USB C male to female extra-long data cable extension cable is made of solid materials, fine workmanship, and thicker wires. It can quickly connect to the docking station to read files. The USB 4 cable is compatible with Thunderbolt 4 extension cables and power supplies. The 8K video transmission speed is very fast. The nylon outer cover is very advanced and comes with a drawstring. This is the longest and fastest extension cable I have ever bought. My 1-meter Thunderbolt cable plus this 3-meter extension cable can still maintain full speed, and the transmission signal is very strong. The 3-meter distance plus the 1.2-meter cable that comes with the AR glasses can still perfectly present the picture, without any lag and enjoy the smoothness. The extension cables bought from other stores are either very short or very slow. This one is really good. Although it is a braided outer skin, it feels very soft. It is indeed a good cable, unlike the hard ones from other stores. The cable material is very good and tough. ... show more

High quality USB-C extension cable with impressive specification
Size: 8K Video for monitor extension cable 10FT
At 10' long with support for 8K video transmission, 40Gbps data rate and up to 140W fast charging, this is a high-quality USB-C extension cable that should satisfy just about any use case. The cable construction is very good with high quality strain relieved plugs and heavy braided nylon cable covering that provides good protection for the cable. Although the braided nylon is very tough it should be noted that it's a little stiff and might make cable routing a little more challenging. In my testing it has worked as expected for everything from multi monitor setups through hubs to fast charging for my pixel phone. A nice convenience feature is that the cable specifications are printed on the connectors, so you never have to wonder if problems are being caused by an older spec cable than is required. I would have liked to see it include a USB-A plug converter to add some versatility, but it is a very good cable, nonetheless. Easily recommended. ... show more

Docking stations always come with ridiculously short USB-C cables. The reason for that is relatively expensive retransmission chips. Without them USB-3.2 / Thunderbolt 3/4 cables are limited to 1 feet length otherwise it will be impossible to achieve such high connection speeds. If you have a single laptop to connect, that short cable may work. But if you dock a laptop, phone with Alt DP and mini pc you need a longer cable to be able to reach them all without moving anything around your table. This cable is up to specs. My older one was very chip and often lost sync for video connection due to high transmission error rates. This was annoying as the picture would suddenly disappear and I have to wait for 5-10 seconds for the monitor to resync. With this cable monitor never re-syncs, over-hdmi sound never quits too. ... show more

Good cable
Size: 8K Video for monitor extension cable 10FT
I have very infrequent use for this extension cable. Occasionally, I need to connect a monitor far away from the video source and this is great for that. I don't have any 8K devices, but the 4K devices work just fine with this cable. I also tested with some NVMe SSD (just for testing, normally I don't have to go that far to connect to SSD) and it worked just as well as any other good quality cable I have. Power delivery also seems fine, although I only tested up to 100W. As with any 8K cable, it is rather stiff and thick. There is really no getting around that because of the gauge and shielding needed for those cables. The braiding looks solid, the connectors have good stress relieve boots, and overall it looks like a cable that would last a while. ... show more

Great for extending a USB-C Dock cable -- Don't go over 16'
Size: 8K Video for monitor extension cable 10FT
Very nicely sheathed cable. My existing 3' USB4 cable from my laptop dock wasn't able to reach my Dell laptop on the back desk where I like to keep it. This extension was perfect to extend the reach of that fixed length USBC the additional distance so that I could route it out of sight and not have to keep the laptop on the same desk as the screen and keyboard that I use with the dock. It supported all of the functions of the dock (video, ethernet, USB, Power) that made a single connection to the laptop feasible without a problem. The dock currently has two 34" monitors attached and I don't have any issues after extending the factory cable. So the quality is enough for all of my dock functions. 5 stars. ... show more
