  • Great
Size: 9.8 Feet
Works great. Cable is thicker than average so keep that in mind for cable routing. Also a little "tough" on flexibility. I got this because I wanted a cable that supported high refresh/resolution but also had enough length to fit in a monitor arm that "hides" the cable. My previous cable worked fine, but in the monitor arm it's length was too short to reach the GPU. Great cable from a certified brand. ... show more

  • Great for streaming to a hotel tv

Great for streaming from a Pixel 9 Pro to a hotel tv and not needing to be by the TV when streaming. Especially when you can't cast to a hotel tv

  • Important and Very helpful upgrade!
Size: 6.6 Feet
I had a 4yr old DP Cable I was running with a 4090 and a 2k 240hz Monitor. Upgraded recently to a 4k 240hz QD-LED Monitor and started getting black screens, stutters, delayed loading, and a few other random issues. Read up online that if you are running a 4090, Maxed Out, on a high end Monitor, you’ll want to get a V 2.1+ Certified cord. The one I had was an older V 1.2. Plugged this cord in, which I should say feels and looks Incredibly sturdy and has awesome connectors with a solid construction that fit perfectly. Turned on my computer, No More Black Screen from the moment I fired my rig up. Zero stutters, No more delays, running at the full 4k 240hz @10-bits. Not bad at all for under $20. Great product, solid construction, Cheap upgrade for future proofing, and fixed a lot of headaches for cheap. ... show more

  • Excellent Cable
Size: 6.6 Feet
Finally a DP cable that won't cause black screens, flickering, or other bizarre screen issues. Plug in and works great, able to set high refresh rate and G sync!

  • Nice Quality
Size: 6.6 Feet
I got this cable to solve my weird issues with flickering or unstable signal. It mostly fixed all of my weird monitor issues. Now the only issue I have is the stupid dynamic contrast issue, but it happens a lot less.

  • An absolute must if you are using a DisplayPort Cable! ˗ˏˋ ★ ★ ★ ★ ★ ˎˊ˗
Size: 6.6 Feet
This cable from Cable Matters is a huge home run! I absolutely love the fact that it "clips" in to a female port. This will save me and you all a lot of headaches. No more worrying about the cable unplugging when moving your laptop, desktop or monitor. Another absolute plus for me is that it is using the newest and greatest DisplayPort generation of cables (Generation 2.1) plus it is VESA certified. VESA DisplayPort Cables are certified cables from VESA or Video Electronics Standards Association, which is an association to make the buyer’s life easy. All the DisplayPort must pass certain quality checks to meet their guidelines and get the certification. Without a doubt this DisplayPort, which is VESA Certified, will give you far better quality and performance than standard ones. Why? VESA tests everything about a DisplayPort cable, like Built Quality, Performance, Colors, and more. So buyers get the best cables for a perfect and smooth experience. 5 Stars all around. ˗ˏˋ ★ ★ ★ ★ ★ ˎˊ˗ ... show more

  • Good Value
Size: 6.6 Feet
I purchased this cable to run 240hz for my 49" Odyssey G9. Originally I was unable to get the monitor to run 240hz due to what I thought was a cable issue. I purchased this cable to try to fix the problem, but it persisted. A quick update to my monitor firmware and I was good to go. This cable does not flicker or have any problems with 5120x1440 (49" curved ultrawide) at 240hz powered by a 4080S. ... show more
