Cable Matters 2-Pack Unidirectional USB C to DisplayPort 1.4 Cable - 6ft, Support 8K@60Hz / 4K@240Hz, Thunderbolt 4 to DisplayPort Cable, Display Port to USB C, Black - Not for Portable USBC Monitor

I couldn't find any reliable HDMI 2.0 to Display Port 1.4 adapters or cables to connect my Lenovo laptop to a bigger monitor that could handle 240 Hz. Sadly with HDMI the max limit was 144 Hz so I decided to give this one a chance and I'm glad I did!!Was worried at first because of the reviews, but they probably got lemons since this is working exactly as intended!! It allowed me to go to the max Hz of 240 right away.So far no issues or flickering, it is a solid cable might want to be careful of how much you bend it though. If I notice anything bad with time or something does occur or it stops working completely I will update this review. In the meantime THIS IS THE CABLE TO BUY FOR MY LAPTOP PEOPLE!

does exactly as intended, 1440p at 240hz with G sync on my laptop🤝

I’ve been using the Cable Matters USB-C to DisplayPort 1.4 Cable with my 16-inch M4 Pro MacBook Pro and Samsung LC34G55T ultra-wide monitor, and here’s my experience:System Setup:My MacBook Pro has the following configuration:Apple M4 Pro chip with 14-core CPU, 20-core GPU, and 16-core Neural Engine.24GB unified memory and 1TB SSD storage.Three Thunderbolt 5 (USB-C) ports, HDMI port, SDXC card slot, MagSafe 3 port, and Liquid Retina XDR display.My monitor is a Samsung LC34G55T ultra-wide, with a resolution of 3440 x 1440 and refresh rate of 165Hz, which I used for this review.Performance:The cable works as advertised. It successfully achieved the full 3440 x 1440 @ 165Hz refresh rate on my Samsung monitor, something HDMI couldn’t handle. It provides reliable video output via DisplayPort Alt Mode from my MacBook Pro’s Thunderbolt 5 ports.2-Way Operation:I cannot confirm the cable’s 2-way operation, as I don’t own a USB-C input monitor to test it. I use the cable solely for my Samsung LC34G55T monitor, and it has performed exactly as expected.Final Thoughts:This cable does exactly what it promises. It provides reliable and consistent video output for high-refresh-rate monitors. It’s a solid choice, and I recommend it to anyone whose needs are similar.

Pretty straightforward.I used it to connect a Mac Studio M1 Max to a Samsung odyssey g9 57. USB C to DP. I had read some horror stories about people having issues with the wrong cable and everyone recommended that one.I didnt have any issues and it's cheaper than others you find at big box stores. I've seen cables that feel more premium, but it's not like I am going to be handling it every day.

Solved a major problem that I had where my widescreen monitor (Samsung C49RG9x) would not connect at wider resolutions after a MacOS update to Sequoia 15.4.1. I was using a DisplayPort to Mini DisplayPort plugged into a dock that then plugged into my MacBook via USB-C. This USB-C to DisplayPort cord plugged directly into my computer and allowed me to connect at 5120x1440. I am VERY pleased.

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 ;-)

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.

Product worked great where others failed. Used to connect my computer to a UWQHD monitor. Others that claimed the same compatibility did not even send a signal. They would display with my phone connected but not my pc's (tried 3 different computers). This product worked perfectly after finding it mentioned in a forum conversation.If you don't think it is a cable problem, check again...it might just be the problem.
