Amazon.com: Cable Matters Bidirectional USB C to DisplayPort 1.4 Cable 6 ft, Support 8K@60Hz, 4K@240Hz (Thunderbolt 4 to DisplayPort Cable, DisplayPort to USB C Cable) Black - Not for Portable USB-C Monitor : Electronics

I have a Mac LG 5k Thunderbolt monitor that I wanted to use with my pc and gpu card. My GPU did not have a thunderbolt cable output. I bought a DisplayPort to Thunderbolt-USB3 Cable. This worked out of the package. I had bought a previous cable that worked intermittently. Was very frustrated with it. I am happy this this cable.

This USB-C to DisplayPort 1.4 works great when the USB-C connector is connected to the host device and the standard DisplayPort 1.4 connector goes into the monitor, however it does not work at all when in reverse.This has been tested on two portable USB-C monitors (CASKING 1080p 240Hz/300Hz 15.6" and UPERFECT 1600p 144Hz 18") and a Samsung OLED G8 which has two USB-C inputs.USB-C on the monitor, DisplayPort as the video source = No goDisplayPort on the monitor, USB-C as the video source = Works really well1 star off because of the wrong advertising that it is bi-directional cable when it is not. 4 stars because the cable works great as long as the source host has a USB-C output (DP Alt Mode), which most modern laptops do now.

I have a Lenovo Yoga 900-13isk2 that I purchased in 2016. I wanted to replace the multiple monitor setup I had been using with a single 49-inch ultrawide monitor, but I could not determine whether the graphics interface would support it or not. I had the Lenovo USB-C to HDMI adapter which I tried with an LG 38-inch (3840x1600) and it worked with the refresh set to 75 Hz. However, the monitor I really wanted was the Samsung Odyssey G9, which has a native resolution of 5120x1440.According to some support documentation I found (with the help of the Intel community board), the graphics interface (Intel HD Graphics 520) is capable of 5120x1440, but each laptop manufacturer's implementation may or may not support it. Lenovo support was less than helpful, so I took a chance and bought the monitor (for $999 for Black Friday). It would not work with the HDMI adapter. The computer would go into a connect/disconnect loop, never showing an image on the new monitor.So, I started looking for another adapter, thinking that a DisplayPort-specific adapter might work. That's when I noticed this one. It worked immediately! Interestingly, it displays 3840x1080 as the "recommended" setting, but it also offers 5120x1440, which works great! With the new monitor connected, my laptop is driving it at 5120x1440 at 60Hz, and simultaneously driving the built-in display at 3200x1800 at 60Hz.Not only is this a cleaner physical layout than three 24-inch monitors, it is also much faster than the individual monitors because a docking station using DisplayLink is not required. (DisplayLink uninstalled, thank goodness ;-)

After purchasing this and after it shipped I got a little nervous because I read some of the bad reviews that said it was not bidirectional and doesn't work from a DisplayPort source to a USB-C monitor. This was my purpose in buying it, so I was concerned. But now that I've tested it, it does work in that direction. I have it plugged into the DisplayPort output of my laptop dock and going to the USB-C input of my 4K USB-C monitor (I also have the monitor plugged into electricity with its power cable). This works perfectly. I get the highest resolution that my monitor supports (4K@60Hz). I don't know why this apparently didn't work for others, but I'm happy.
