Passive DisplayPort Coupler

I had bought 2 cheaper Display Port cables from Amazon that were $8.99 each. I wanted to connect my Wacom Cintiq to two separate PC's using a display port switcher and USB switcher. My Cintiq monitor kept glitching and even turned black intermittently. At first, I thought the culprit was the switcher, but I was mistaken. That's when I discovered that not all display port cables were created equal. I returned both those cables and searched for the best quality Display Port cables I could find. I read through a lot of reviews and chose the VESA Certified ones from MAXONAR. I ordered two. The Cintiq worked beautifully with my work computer, but the screen glitched with my personal pc. Turns out that the display port female on my personal computer was loose, I switched it to another port and it worked fine. I'm very happy with my purchase.

Perfect unit. I was able to actually get 85 herts refresh on my new 1440p resolution monitor with gsync and using the following two 25 foot cables, a total of 50 feet away. The quality of the cable matters. KabelDirekt 25 ft 4K 60 Hz DisplayPort cable, version 1.2, male connector with locking and nylon sheath - PRO Series I will next try two 20 foot cables to maybe get the 144 hertz my monitor was advertised for. If you use that brand cable I think you will be in luck. That 25 foot cable by itself (the longest length) can achieve the 144 hertz refresh rate. In my situation I need a bit longer and perhaps I can fit into 40 feet.

I had a generally positive experience with the Cable Matters 2-Pack DisplayPort to DisplayPort coupler (female-to-female). Shipping was prompt, and both adapters arrived well-packaged and in excellent condition. There were no bent pins or visible defects, and the set was ready for immediate use. In terms of product quality, the couplers feel well-made for simple connectivity tasks. The housings are sturdy with a secure fit, and the internal connections appear solid. I used them to extend a DisplayPort connection between two cables, and the ports aligned correctly without requiring excessive force. Once connected, the signal remained stable, and I did not experience flickering or intermittent drops during normal use. These adapters are straightforward in function—there is no signal conversion involved, so they are best suited for extending existing DisplayPort cables rather than adapting to other interfaces. For that use case, they perform reliably and maintain signal integrity for both video and audio as expected. From a value standpoint, this two-pack offers reasonable utility for the price. Having a spare coupler on hand is convenient for setup changes or additional displays, and the set eliminates the need to purchase single units separately. Overall, these couplers meet expectations for simple DisplayPort extension needs and provide dependable performance without unnecessary complexity.

Neither worked with multiple good cables that work individually with multiple monitors. Tried repeatedly, no signal passes through them. Update: Even after returning them and getting a refund, Cable Matters still continued to try and ensure that their product works. I received a replacement and the new replacement does work.

Both couples received are completely non functional. Bought to extend Valve Index but tested with 2 monitors as my index isnt here yet. Tested with 3 separate sets of cables which I tested individually before trying with the coupler. No direction or combination of cables worked. Based on reviews there's a 1 in 4 chance your product will not work. Amazon should remove this until Cable Matters starts doing QA on these devices. Do not buy.

Was using on display set to DP 1.2, would get blinking every few minutes got really annoying. Switched to 1.1 and flicker totally went away. Bought the powered repeater version so I could switch back to 1.2 and now these are collecting dust. If needed for DP 1.1 these will work, anything higher and don't bother. Also only used to put 2 three foot cables together, wasn't going super far. TVs are wall mounted and it's tough to get to the wires so was easier to add onto the cable rather than switch it.

Seriously I'm hard on equipment, most cables last 30-45 days tops. The other couplers I've tried wouldn't last more than 30 and that includes the gold plated $30 ones you can get on amazon. These were $5 each! The first of these just failed today after 90 days and it was a 2 pack for $10 so I'm a very happy customer. On top of that they transfer 4k @ 60hz plus sound with no problem. Just in case someone is trying to do what I am, I am using a MDP to DP cable on one end and a DP extension on the other end, works great and I still show its reading as a DP 2.1 connection. Don't waste your money on the expensive ones.

I used this to connect two 3.3ft DP 2.1 cables connected to a 1080p monitor running at 144Hz. It worked perfectly. When it comes to high refresh monitors, you have to ensure that every component can support the higher refresh rate, from the graphics card, to the cable, to the monitor. I also have the cables connected into an angled DP adapter into the monitor and it all works perfectly.
