Cable Matters 32.4Gbps Long DisplayPort 1.4 Cable - 16ft, Support 8K 60Hz, 4K 240Hz DisplayPort Cable 1.4 with FreeSync, G-SYNC and HDR for Gaming Monitor, PC, RTX 4080/4090, RX 6800/6900

No signal issues or screen artifacts with the 4.9m cable length using a 3440x1440 monitor @ 165hz. Cable design is fantastic at an excellent price.

4K@144Hzで問題なく利用できています 現在併売されている同社製の80Gbpsケーブルと持ち手のサイズは同じでした 持ち手の耐久性は10年以上前に販売されていた同社製の旧式ケーブルより 向上しているようには見えないですが、まあ安いので壊れたら買いなおせばいいかなと… 4.9mサイズを購入しましたが太めのケーブルで硬いです

Works perfectly, allowed me to move a second monitor to a spot in the studio I couldn't reach until now.

This review is for the 16 feet Cable Matters DisplayPort Cable 1.4 . TL;DR | The 13 feet and 16 feet cables are NOT VESA certified. They have issues that can potentially damage your DP 1.4 monitors or even GPU (or not, IDK, flashes on screens seem scary). Note: I'll refer to Cable Matters as "CM", and DisplayPort as "DP" from this point forward. - - - DISCLAIMER: Technically, they aren't claiming that it is VESA certified in the specific products' descriptions. However, there is a good chance you might have been led to believe that all cables are VESA certified because it is mixed up with their other VESA certified cables (3, 6 and 10 feet). I am not a fan of this deceptive advertisement. It's just sneaky. I am rating mostly the product itself. My other rants have little effect on my product rating. I returned the cables and received a full refund as if this writing. - - - EXPERIENCE: I was having issues - my monitor would flash bright lines randomly after the system has been working under load. I have troubleshot this and did not initially want to blame my brand new cables, as I thought they were VESA-certified. CM has always been my go-to and I have never had issues with them. Anyway, I purchased two identical CM DP cables, and either would cause signal flickering on two different monitors. After my almost month-long troubleshooting, CM and I both agree that the issue is in fact with their cables. SUPPORT WOES: They told me ALL 10ft+ cables do this (i.e. including competitors). They suggested that I instead purchase THEIR 10ft and 6ft cables, PLUS their own signal booster/repeater to connect those cables. This information is not true. VESA can certify DP 1.4 cables up to 15 meters (50 feet). They implied that this information is outdated, pointing out that this was in the "Archive FAQ" section of DP's website. (The only reason it was in the "archive" was because of the fact that the "Current FAQ" is all about DP 2.0). - - - RETURN AND REFUND: They did ask me to return the product before I can get a refund. It took weeks because I've been temporarily disabled physically and could not drive to the post office (USPS label, no package pickup, outbox slot too small for two 16-foot DP cables), and they wanted to physically get the cables first. They did send a label only. I think it's fair, but relatively frustrating when compared to almost every other company I've dealt with on Amazon. I just purchased another VESA-certified cable and had to spend a good chunk of my day managing my cables. (It was a pain having to remove their existing cables and replace them with a new one. I wish I could've just cut their cables as it would have been faster). - - - MY EQUIPMENT: Acer XB32U GX, Acer X34 GS, RTX 3090. I replaced my PCIe power cables when I was trying to figure out why my monitors are flashing white lines. Thank goodness it was not my GPU which was also new and would be really hard to replace. - - - CLOSING TIP: Upon checking DisplayPort's website for certified cables, only two brands are certified with a length of 5 meters (ones which are available here in Amazon): KabelDirekt - 1122 and StarTech - DP14MM5M . I got the former as a replacement. I am attaching a photo of what a VESA-certified 5-meter cable looks like. It's a magachonker. CM's version of it is almost as thin as any other short DP cables (including the stock cables). I have not experienced any issues with the real VESA-certified cables, and it's been almost a couple of weeks since I've switched. Also, do not try to be cheap like I was. The VESA-certified cables cost $30+, while CableMatters' is about $20 at the time of writing. If you NEED DP 1.4 (vs. DP 1.2), there is a good chance that you are using expensive gaming monitors and an equally capable GPU. It *could* damage your other equipment, or the issue might just be related to it not being able to push the required signal. I have not verified this. To be clear, I have been using CM's cables for a long time, and have had no issues with them. HOWEVER, I think it's irresponsible selling these and especially mixing these with their other good products. At the end of the day, they did the right thing, but only for me. They should pull these cables out, or rebrand them as DP 1.2 (the length might work fine for DP 1.2. Been using their 25-ft DP 1.2 cables for years without issues). FINAL DISCLAIMER: My experience is specific to one customer support person only and might not be fully representative of the whole company and the brand as a whole. - - - VERDICT: I do not recommend this particular product (16-foot version). ☆☆☆☆☆ | 0 stars out of 5. It works, with issues that are not fun. This cable should not exist and has the potential to damage CM's brand. This review is for the 16 feet Cable Matters DisplayPort Cable 1.4 .

Clear clean signal. This brand was recommend to me by a IEEE senior electronic engineer. He was right! Good product.
