I'm using the 35 foot version of this display port cable to hook up to an ultrawide 21:9 monitor running at 2560x1080 75hz on an LG 34 inch (34UM67) Monitor. I've been using this cable since 2015, and it works perfectly. I keep my PC inside a closet to keep it nearly silent, its why I needed such a long extension cable.Eventually I may get a higher resolution ultrawide and at that point i'm not sure if this cable will still work. But on the other hand, I was thinking of maybe sticking with 2560x1080 but getting a higher refresh rate monitor of 120hz or more, but not actually sure if this cable could do that either.I've setup custom resolutions in Nvidia control panel up to 21:9 5120x2160 75hz and it runs, but i'm not sure how that works exactly. I'm not sure if all that 4k data is actually being sent to the monitor, or if the 4k is being downscaled on the PC before it is sent through the display port cable. So i can't be sure that it would actually be able to do a 4k ultrawide signal through the cable.Whenever I get a new monitor that has a higher refresh rate above 75 hz or a higher resolution above 2560x1080, I'll edit this and put in the results if it worked or not.**** EDIT [Oct 2019] ****Just wanted to update. I tested this 35 foot on a monitor that was 2560x1080 which ran at 160hz, and it did not work. I had to use a much shorter 15 foot cable to be able to achieve 160hz at 2560x1080.75hz@2560x1080 at 35 feet is pushing this cable... the other monitor i tested didn't like it and would only run at 60hz. So it likely depends on how picky the monitor is also.Also. Even at 60hz, I could not get G-Sync to work with this cable, so this is something that could happen depending on the monitor brand, but maybe the G-Sync didn't think the distance was good enough to allow it. Oddly though, I was able to get 75hz freesync working on my original monitor with it.

This StarTech 35ft DisplayPort cable is great, it handles 1080p 144Hz at 35ft with zero issues for me. I've been using it daily for a couple years now for my primary monitor. Strongly recommended.

As stated in the headline, this works perfectly with a high refresh rate monitor! Freesync/Gsync also is applied by default when using this cable! Did not notice any stuttering! Everything is buttery smooth and picture quality is perfect! On a side note, make sure to cap your FPS limit to that of your monitor if your want to take advantage of freesync! Very happy and relieved that this works! :)

I bought a cable of 6 feet (72 inches) as indicated on the package. When I saw that something was wrong, I took my measuring tape. The cable was 64 inches, not 72. A good cable, very strong, but without any indication on the wire or the plugs. Be carefull when ordering this item.

I currently have 2 of the 15ft variant these going from my dual 144hz GSYNC compatible monitors to the ASUS STRIX 2080Ti in my PC. The reason I have done this is because like MANY 2080ti's (moreso the after market ones), it does produce a decently noticeable coil whine. Most people wouldn't be bothered by it. I am, so I moved my PC under my desk in the corner of my room to alleviate the issue. Everything is working as it should. GSync, full refresh rate, no degradation in quality.Whether or not this actually lasts, we'll see. But as of last week this cable WAS on the VESA certified list on the official DisplayPort website, so we'll see. If anything changes, I'll update this review. But after a week, everything seems peachy.

Iam very happy with the manufacture of the product and its fit and finish. which is important for something that is hidden away, in the background.

Cable seems to work all right, I'm still having a glitchy desktop issue with artifacting, but I'm sure that has something to do with my Gpu lowering it's core and memory speed when idle.

On the official StarTech.com page for this product (DISPLPORT20L), it states that this is only capable of DP 1.0 speeds, which would be 2K @ 30Hz, or 10.8Gbps bandwidth. When I saw this, I tried to cancel my order, but it was too late... so I decided to just try it and see. Well, I'm glad I did... maybe I just got lucky, but my cable is working with zero problems!I am currently using this for my gaming monitor, which is 2560x1440 @ 165Hz. The connection is very solid... the signal has not dropped out, even if I mess with the cable. It is a thick cable, but not unmanageable. I have it connected to a monolith-style SFF PC case, and it does not have trouble making the bend from the bottom, out the back.Very satisfied with this purchase! YMMV, since officially this cable is not officially rated for the bandwidth that I'm getting out of mine.

lo uso para un monitor a 144hz, todo excelente sin problema, tener en cuenta la distancia ya que 1.8m podria ser mucha si tienes el monitor a un lado del gabinete

Works as expected.Working fine on a resolution of 4096*2160 @ 60fps.Sometimes fall back to lower resolution when booted up.Had to restart for getting the full resolution.

Perfect, fixed all my cable woes.The listing states"The DISPLPORT6L 6-foot DisplayPort® Cable supports a maximum bandwidth of 10.8 Gbps, and is capable of providing higher performance than either HDMI® or dual link DVI and supporting next generation multimedia applications with a maximum resolution capability of up to WQXGA (2560×1600)"This is misinformation, the correct specs are,The DISPLPORT6L 6ft DisplayPort™ 1.2 Cable with latches provides a secure, connection between your DisplayPort-equipped devices and is capable of providing higher performance than either HDMI® or dual link DVI.The DP cable supports high resolutions of up to 4k x 2k (3840 x 2160) @ 60Hz with a maximum HBR2 bandwidth of 21.6 Gbps.

Collegato un secondo monitor per il mio studio di registrazione, nessun problema con una scheda video Radeon su hackintosh!6 metri di qualità che però si fanno sentire sul costo
