Club3D CAC-1557 USB Type C to Displayport 1.4 Bi-Directional Cable with 8K 60Hz, 4K 120Hz HDR Video Support 1.8m-6ft M/M

works great between my AMD RX 570 (which has full size displayport) and my LG Ultrafine 4K (first edition). running OSX on a hackintosh. only gripe is it takes 2-3 seconds to change resolutions, plus USB hub and light sensor don't work on monitor, but cable is great. the "bidirectional" nature of this cable works fine for me.

This adapter works perfectly with my 49 inch Samsung Odyssey monitor. My setup runs from the monitor into a KVM, which then connects to both my work laptop and my home computer. With this adapter, I get full resolution and full refresh rate without any issues. There is no stuttering, no flickering, and no signal drops. Everything is stable and works exactly as expected. It handles the high resolution and refresh rate of an ultrawide monitor without any problems. If you are running a high-end display through USB-C and need reliable DisplayPort output, this adapter does exactly what it claims. Highly recommended.

An actual USB-C to DP bidirectional cable that works! FYI: the DP end only works with an original DP enabled device such as DP/mDP ports on PCs, laptops, monitors w/DP out, etc. It will not activate with DP from a GPU/video card nor dock (without internal converter). Tested: ✔️1) Mac w TB1/2 to miniDP/DP adapter to this cable going into USB-C (DP Alt Mode) enabled monitor; Mac to Dell MST monitor to this cable going into USB-C (DP Alt Mode) enabled monitor ✔️2) PC mobo DP with this cable going into USB-C (DP Alt Mode) enabled monitor ✔️3) TB3 laptop/Samsung tablet to DP monitor ❌4) TB3 laptop to TB3 dock to this cable into USB-C enabled monitor ❌5) PC GPU DP with this cable to USB-C enabled monitor Cable construction seems sturdy and the thickness is fine since this is USB-C focused wiring. The housing for the DP end is better then some but doesn't look like it will hold up to extended plugging/unplugging (connector can wiggle a bit and have a slight angle to it), so I wouldn't move it much after placement.

I used this to connect my 4060 with DP port to a portable monitor's "full feature" usb-c port. It worked, while the previous Startech bi-directional cable I purchased did not. Packaged well for a cable. Satisfied.

Compatibility not good

I'm using this to connect my portable USB-C monitor to my desktop PC that doesn't support DP alt-mode through USB-C and it connects at full resolution without any issue. Recommended.

The cable assembly appeared sturdy and well made. My application for this cable is for connectpro KVM switch based passthrough of a 120hz 4K monitor powered by a thunderbolt based Displayport (over USB-C alt mode) from an M1 based apple laptop. Wasted a lot of time troubleshooting due to this being a faulty cable. The cable signal strength was unstable which caused a frequent triggering of the DP link training. Once I replaced this cable with an alternate brand this problem was resolved.

I had high hopes but it did not work for my use case. I bought it because it says it's bi-directional and one of the images even has a two-way arrow between DisplayPort and USB-C. Unfortunately, it didn't work for me with an RX 580 nor a Radeon VII paired with an Acer PM161Q monitor. Don't know if it would work with other products but I'm very disappointed. As far as I know there is only one other cable (much more expensive) that claims to be bi-directional this way. After this experience, I'm skeptical and not willing to put any more money into testing. It could be that it just isn't a possibility right now. Besides not working for me, it looks like a great cable to go from USB-C out to a DisplayPort monitor.

I have been looking for a way to enable G-Sync on my monitor paired with a Lenovo Legion 5 laptop that has Geforce RTX 2060. This is the only way to enable it - amazing! I plugged the USB-C end to my Legion type-c port and connected to the display port of my Dell G-Sync compatible monitor and voila! Now I can get refresh rate of 166Ghz and crisp fluid frames when gaming. Also, i can see the difference when watching ultra HD movies.

Eu tenho um Macbook Pro 2019 e um monitor 34GL750 da LG, a resolução máxima que o cabo chegou foi a de 2560x1080 com 144Hertz.

Bought this to connect Samsung G7 gaming monitor to my Razor Blade laptop. Achieves 240Hz refresh rate.

Very good I like it

Bought this to use with a USB-C monitor, an old Mac Mini with mini display port, and a DP to Mini DP adaptor. The Mac Mini is also hooked up to a graphics tablet through HDMI. Sometimes, when I wake the Mini from sleep, my USB-C monitor shows no signal (even if I unplug the HDMI), and I don't know what component is causing that, but it's pretty good. Edit after two years: I'm still using this cable on my Mac Mini but now it's running Ubuntu and I have zero issues. The component that was causing the problem was MacOS. 🙃
