StarTech.com USB 3.0 to Dual DisplayPort Adapter, 4K 60Hz, USB to Dual DP Display Adapter/Converter for Mac/Windows

I have multiple screens in my home office, and it always frustrated me that I could only use 2 with my Mac mini. That was until I saw this adapter in a YouTube video, and it seemed too good to be true. But sure enough, there were many more than the suggested 2 in use. On impulse I made the purchase, and to say I'm happy is not doing my feelings justice. I can now have all 4 screens outputting from my beloved Mac, I can multi task to my hearts content. I am a little worred about getting confused when I next need to share a particular screen but that's nothing to do with this product and everything to do with my squirrel mind. The setup was easy, there's a driver you download from the website, for Mac you decompress and choose your OS version. Install and set up some permissions. Then it just works. There's no lag, I see a full screen on all 4 monitors, and there's no issues I can see at all right now. Very happy with the purchase and to enable me to start to use my full screen potential again, well worth the money.

Finally, I have a solution to drive my 5120x1440 ultra wide from a non thunderbolt windows laptop. For month I have been struggling (hacking drivers, using custom monitor profiles etc) but in all cases, I’m limited to 3880 x 1080 from a non thunderbolt usb c connector. This item not only drives my ultra wide at native resolution at 60hz (displayport) or 30hz (hdmi) it also drives another monitor at the same time - this actually goes beyond the stated specification of a single 5k ultra wide. It also works with pc or Mac and the cpu impact is minimal - I can drive my ultra wide from a surface pro x with 20% cpu utilisation when dragging windows quickly which is usually a high cpu usage event for displaylink. Using this my thunderbolt 4 dock drives 3 monitors (including the 5k ultra wide), 1gb Ethernet, a 4k webcam and a usb keyboard and mouse from a single usb c, from a surface pro x. It’s not cheap, but we’ll worth it for those with 5k ultra wides and non thunderbolt laptops. *update* it also can drive both my new mateview 4k+ monitors from a surface pro x as well.

Top product, few minutes set-up, plug and play and so far so good, working off an old lenovo. Expensive, yes, but the freedom to have a couple of monitors outweighs cost. Worthy and reliable, tech support is there, along with drivers if needed...install drivers first if required, but really easy product that works.

Works with the new M1 Mac mini and the Displaylink Manager installed. And that’s via a USBC dock. No noticeable performance issues yet. Update, have now used this for video work and so far its been flawless, note the display will come on after login which is when the DisplayLink manager will load and automatically activate the screens, but I am really happy with this setup. Together with my docks cdmi output, I know have 4 screens running well. Its expensive but given the New M1s are limited to just 2 screens natively, this allows for more.

I use this on an AMD R9-7950X system used for software development, and as such it has no discrete GPU, originally relying on the iGPU for a three-monitor setup, 1 UHD @ 60Hz and 2 WQXGA (2560x1600) @ 75Hz. As the AMD iGPU driver frequently crashes, in an effort to reduce these crashes I switched to using this DisplayLink adaptor for two of the monitors. I should note that if you play 4k60p video on YouTube, you will get a couple of lost frames every second: the device's DisplayLink driver uses a substantial amount of the processor's iGPU to render. 4k30 and 2560x1440@60p seem to work OK without lost frames beyond the first couple of seconds of playback. This may well be down to a limitation of the relatively limited iGPU on the 7950X. You will also notice increased screen tearing when moving windows about on the DisplayLink connected displays. In case it isn't obvious, you won't be able to use this solution for a boot monitor to get into your system's BIOS: you need a directly connected monitor for that. Despite this, I would much rather have a stable system than one that regularly crashes, and so far this seems to be holding up well.

My Macbook is limited to 2 usbc ports, either of which can be used for a single extended display. Plug 2 in and only 1 will display. I downloaded the most up to date DisplayLink software for the Mac, bought this device (as my displays use a display port (not hdmi) and plugged them in. Job done! Super easy, Mac recognized the displays and I can crack on.

Great product that does what it says. That being said, buyers should be aware that it does have a limited product life. Mine has lasted ~4 years, having been used almost daily. The USB 3.0 cable attached to the adapter eventually becomes "sensitive" and then merely stops working. Shame that the "product support" window is only 2 years.

仕事PCをHDMIケーブルで2560×1440 144Hzのモニターに接続しても60Hzまでしか設定出来なかったため、本製品を購入しました。 DP1.4ケーブルを使い、本製品を使用して2560×1440 144Hzのモニターに接続したところ、144Hzで設定出来ました。 ディスプレイチェッカーサイトで見ても144Hzになっています。ただフレームレートは使用状況によってはスクロールで60fpsほどに落ちていると感じることはあります。ただマウスカーソルはずっとヌルヌルです。 使用環境は 一般的なビジネスノートPCで、 CPU core i5 10210U メモリ 8GB×2（4GB×1から入れ替えました。） 内蔵グラフィックで普通に使う分には基本ラグもなく使用でき、USBの通信速度でどうやって実現しているのかわからないマジックアイテムです。 仕事PCで管理者権限が無かったためか、PCのUSB端子に挿しただけではドライバは入らなかったですが、サポートページからドライバをダウンロードしてインストールすれば動きました。 注意点はPCに直挿し推奨な点です。 USB3.0の延長ケーブルを使ったところ、ウィンドウのドラッグや、スクロールにてラグが発生しました。（私の使った延長ケーブルがダメなのかもしれません。） 直挿しなら問題なく使えるので直挿しで使用することにします。 1ポートしか接続していませんので、2ポート使った時の挙動は分かりませんが、とても良い商品だと思います。 耐久性についてはまだ使用し始めたところなので、期待を込めて星4としておきます。

Sui nuovi MacBook Air con chip M (1 o 2) c'è una limitazione e non gestiscono più di un monitor esterno. Con questo prodotto ne ho collegati TRE (quattro quindi con lo schermo del MacBook!) Due sulle uscite dello startech e un Arzopa USB direttamente sulla usb-c. Ricordatevi solo di installare i DisplayLink drivers ;)

I got a 2015 Macbook Air model that neither has a USB port and wish to extend the display to my dual screen set up. While my work laptop has consumed HDMI ports, I was on the lookout for DP adapters for 4K 60Hz display. After about 6 months of lookout, I am lucky to have my hands on this. USB 3.0 ports cannot transmit 4K @60Hz, this adapter processes the signal so you get what you are looking for. I am reluctant to upgrade my macbook yet and feel my current one has some life left in it yet. Cons: The device gets too hot on prolonged usage - about to 2 hours. Then the media starts to distort a bit, however this isn't a device made for streaming media on your large screen. Other productivity apps work mighty fine.

The product was easy to hook up and install on my Windows Laptop. For me, there was no need tp download any drivers, it just recognised the screens and functioned first up without any hassles.

I hope this helps others to figure this out... This may be informative for anyone regardless of the cabling they need. Please read the entire review. I have a regular PC with USB 3 Ports...nothing special. I have 2 external Dell monitors. I need 3 screens for work. Make sure you have a USB 3 port available...the plastic tab visible within the port will be BLUE. The blue tab means USB 3. With this slick little adapter, you can use a USB 3 port to plug this in AFTER YOU INSTALL THE DRIVER. The packaging materials provide the URL from which to download the driver. 5 minutes tops from reading the instructions to having the download complete. Note: this adapter is for DisplayPort. My Dell monitors accept several different cables including DisplayPort. MAKE SURE YOU HAVE DisplayPort CONNECTORS ON YOUR MONITORS AND DisplayPort cables (I bought my cables from Amazon, too. I believe they were about $10.00 each). Plug the cables into your monitors, plug the other end of the cables into this adapter, then... plug this beauty into the USB 3 port. I believe I rebooted. after plugging in, too. Voila...3 working monitors. Excellent resolution, no lag time, no flicker...everything I had hoped for. Why This Works: This adapter is basically another graphics card...it can handle the 2 monitors. Your PC's internal graphics card might not be able to handle 3 monitors but all your PC knows is that a USB port is in use. What it is being used for does not matter. (Yes, I know...gross oversimplification but effectively accurate.) This adapter simply WORKS!!! You can count on it working if it has no internal problem. I mention that because the first one I received worked for about 15 seconds then I'd either see blank screens or vertical bars on one or both external screens. Nobody mentioned that so I wasted time troubleshooting. Just return it; it's not working if that happens.. NO BIG DEAL. Sending it back via Amazon returns is as simple as possible. Amazon, true to form, IMMEDIATELY sent me a replacement adapter. My new adapter was in use well before Amazon got the defective adapter back. This is a great product. 5 stars across the board The tech support at StarTech was good when I was troubleshooting, too. They did think it might be my PC but it was not. Naturally they had no way to be certain so kudos to them for faith in their product. I've waited months to write this review. I wanted to make sure. 100% endorsement. If you have external monitors with DisplayPort connections...this will WORK. BTW...I went to one of the big chain computer stores prior to figuring this out on my own. I spent HOURS and $185 on cabling and adapters the simply COULD NOT WORK. My monitors came with cables for one of the other connections on them. I tried to daisy-chain connections into the USB port. That will not work. Don't waste time trying. You may not have DisplayPort connections...I expect StarTech makes some other adapter that might work for you. Bottom line...monitor connects to adapter. Adapter connects to USB. NOTHING ELSE IN THAT CONNECTION CHAIN...and you are good. One final note...I believe this adapter is what is referred to as an "active" adapter.
