StarTech.com USB32DP24K60 USB to Dual DisplayPort Adapter - 4K 60Hz - USB 3.0 (5Gbps) - Connect Two Monitors to Laptop - Multi Monitor Adapter

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.

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 ;)

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.

Buen artículo para trabajar con dos pantallas independientes

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.
