Cable Matters Active DisplayPort 1.4 Repeater, 4K@240Hz | 4K@240Hz Up to 9.8m, 4K@60Hz Up to 24.4m, DP 1.4 Signale Booster for VR Headset/Gaming Monitor, DP Amplifier

Have had this in place for over a year. Does the job well as I've got a cable run that exceeds single cable length recommended distance. Thankful I don't need to work from home with noisy pc at my desk!

Thought I'd leave a review as a lot of items claiming to do similar things sometimes just don't work. However, I've got these running 5m DP cable in and 5m DP cable out at 144hz 1440p with G-SYNC without any issues at all. I haven't had any of the problems some other reviews have mentioned like needing to turn them off / on after power cycling the PC. I used high quality DP cables without VESA certification and they worked just fine. I overspecced everything to 8K standards to leave room for upgrades later.

Update: seems that it does not pass through the resolution, I have a 240hz monitor and the most I can get is 120hz, keep experimenting with windows/nvidia I guess, was 60hz at first. Having a five metre cable between my PC and monitor resulted in black screen glitches, even switching to a four metre cable I got them, often enough to be annoying. As I have some USB connectors on my Asus monitor I can plug this device in without needing another long USB cable to power the device, keeping it very tidy. I used the same four metre cable from my PC into the device, put a new 50cm cable out to monitor - not one glitch since then. I always wondered why a monitor would have USB connectors, turns out they came it handy afterall. Money well spent.

I purchased 3 of these for my 3 monitors on my gaming PC. I was moving my PC to the otherside of the room and after it was all setup nothing worked. Unplugging and replugging things and eventually got one of them working after which I noticed that while everything is plugged in and powered on, you have to power the repeater off and on (just by unplugging and re-plugging the power). This isn't a huge issue for me as I have a remote to control a few plugs, however I do have to turn the power supply off and on for these repeaters whenever I reboot. Again, this is better than having the computer where it was before so it's something I can live with, but not ideal. As for the result, everything works, no perceivable delay (did a reaction test with and without these and got similar/identical results), G-sync works and running at full 2560x1440 @ 165hz on all 3 screens. Pros: no perceivable dip in performance, in terms of resolution, refresh rate, latency or features. Power cable included. Cons: has to be turned off and on after each reboot once you reach the login screen.

This little gadget is the only way I could get a picture in my Valve Index 10 meters away from the PC it's connected to (source port is an MSI 3080 Ti Suprim X). It works even at max refresh rate (144 Hz) without any artefacts nor sound issues of any kind - it feels just like using a normal cable. I'm using it with a standard, cheap passive 10m DP cable from KabelDirekt. The combination costs ~£30 in total which seems quite reasonable given the length. This is a very different experience from the 10m DP active cable from the same brand which does NOT work (no signal).

I'm happy to report that this repeater works flawlessly for me with a Rift S when used in conjunction with a 3m Cable Matters 8K Displayport cable. YMMV, but I also got away with using a 3m Cable Matters passive USB 3.0 extension cable. You may or may not need either an active USB 3.0 cable or a powered USB 3.0 hub instead. The Rift S is notoriously picky when it comes to cable extension, and this repeater seems to be as close as you can get to an almost guaranteed solution without the risk of wasting silly money if it doesn't work. I'd highly recommend giving this a try.

Used this with a short (good quality) 2m displayport extension for a VR headset, made no difference at all. Headset still isn't detected if I try to use the extra cable, the powered repeater just glows blue and does nothing.

Works as promised

Worked to solve the connectivity issues I had with my Rift S and 3080ti.

Using it on pimax dream air. Plugged it in, no issues. Worked on first try. Got it based on watching a video.

3ｍのDP延長と一緒にINDEXの延長に使っていますが問題なく使用できています。ケーブルはDP1.4で3ｍ1000円程度の中華製ケーブルです。補助電源として5Vが必要になります。

UPDATE: Turns out i had a dead outlet in my powerbar. Swapped out to a new one and any brick i used for it powered it and the signal without issue. Tried 5 diffeerent power bricks and plugged into computer and 5 different cables in many configs using all displayports that my GFX card has. Did not extend my signal. The USB cable I bought together as a package (I assume most are seeing thiss due to that package) works great as does the displayport cable that came with the package on it's own. This extender is the thing that didn't work. Blue LED goes on but nothing.

Utilisé pour booster le signal d'un cable Displayport de 7.5m qui me donnait de temps en temps de écran noir. J'ai mis ce répéteur + un cable de 2m livré avec l'écran (9.5 m au total) et depuis, plus de soucis. Pour le moment je ne suis que sur un écran de 4K60p. Le produit est compact et l'alimentation par le cable USB est fourni par le hub de l'écran (ce qui fait que l'écran ne s'allume pas automatiquement par le signal DP, car pas d'alim sur le hub au départ).
