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.

Only received today but literally plug and play on Windows 11 - no driver installation required.I'm a 5th and 6th monitor with a Nvidia GPU (4 monitor limit.) A DisplayPort MST adapter was useless due to Nvidia's programmed limit (my next card will be AMD or Intel for this reason.)Based on the reviews and past experiences with DisplayLink (around 2015), I wasn't expecting much but as extra monitors/information they would be fine/the best I could get. I'm very surprised with the response time and quality, running at 1080p/60hz. I can barely see a difference between the monitors on this adapter, and the same model of monitors connected directly to my GPU (4 of same monitor, 2x GPU, 2x this adapter.)If this adapter continues to perform as it does today, it's a 5star. I'm not sure where the bad reviews are coming from, maybe Mac users. Windows 11, no drivers, 100%.

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.

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.

so I asked for Startech assistance on their website (which i recommend doing) they advised this port would run two x2 external monitors plus my laptop screen ( MacBook air) and it does perfectly, to the point i am amazed at how easy and simple life has become I can drag different applications from screen to screen and have multiple applications open at one time on each screen, I again advise talking to Startech and downloading the correct software but just follow the instructions.

I don't game or do a lot with video, so can't really comment on video quality. But it was simple to connect up two monitors to my Mac which had been impossible - very happy with that.

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.

This is an excelent product if you want to give a second life to an old laptop that doesn't output 4K at 60Hz through its normal HDMI connections. It could also be used to extend the number of monitor supported by your system, overcoming hardware limitations such as those on the new M1 Macs.Be aware even if you use a discrete GPU or your processor's integrated graphics, this still uses a lot of CPU while encoding the video output, therefore, the refresh rate is not always smooth, especially when your computer is under load (this could be annoying).It's also identified as a screen capture device by both Windows and macOS, what could lead to some problems. In Windows, it only appears after POST/BOOT, but you can use to log into your system. On macOS, it seems like you need to unlock your device before being able to use the external monitors connected through this adapter. It seems like you can't use TouchID when this adapter is connected because macOS thinks the screen is being recorded/shared (this warning could also be annoying since you're not sure if the device is the only thing watching your screen).It might work on Linux, but I wouldn't put much faith on it becacuse on my tests, I had a lot of kernel panics (even with the latest drivers from official manufacturer's website) and sometimes the screen just went blank and wouldn't come back.TL; DR; it could be really helpful, but it's not a magical device, it comes with it's own caveats that you should be aware of.

"I have been using a Startech USB device to connect two additional displays to my laptop. In the attached photo, you can see that the middle monitor is directly connected to the laptop, while the two surrounding monitors are connected to Startech USB devices. Although it's not exactly the same as an original computer cable, it still does the job to an acceptable degree. I am really satisfied with this product that I bought two months ago and tested thoroughly. The speed and quality of the connection are excellent for watching movies or moving images. Connecting the device to my laptop was very easy, and I didn't experience any bugs or blackouts."d I didn't experience any bugs or blackouts."d I didn't experience any bugs or blackouts."

Nach dem Upgrade auf Macbook Pro M3 musste ich leider feststellen, das nur noch 2 externe Monitore unterstützt werden. Dieses tolle und einfache Gerät erlaubt es auf einfache Weise einen dritten Monitor einzufügen.Schnell verkabelt, Software installiert und schon war alles fertig.Das Gehäuse wird nicht heiß trotz hoher Auflösung und 38 Zoll Monitore und die CPU Last der Software ist auch recht gering.Alles in Allem ein tolles Produkt das durch Einfachheit und Effizienz doch beeindruckt.

Connecté sur mon Macbook pro M1 via un Hub USB 3.0 (hub connecté en usb-c sur le mac). Fonctionne parfaitement!

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 ;)

Comporta-se como se fosse uma placa gráfica externa.Muito bom!
