Cable Matters 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’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.

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.

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.

This product does EXACTLY what I needed. It allows me to hook my Apple Studio monitor up to my new PowerSpec G911 PC. I didn’t need or want the speaker functionality, nor did I want to power a laptop. I just wanted to use my PC and my Apple monitor together, and for that it works perfectly.

Originally purchased a Maxonar cable that claimed to be dp 1.4, but that didn't work with my motherboard, only worked with my phone and laptop.This cable from cable matters however worked with my motherboard.I'm only 1 day into using it, so I may come back and change my review later, but for the first day at least it solved a very frustrating issue that almost led to me RMA-ing my motherboard.

Works as described.

Works great and the refresh rate is silky smooth. Now I can game at 4k 120fps

The preferred connection type when driving a Mac.Great quality, fast cables.
