Plugable Dual Monitor Adapter for M1/M2/M3/M4 macOS Systems, Windows, ChromeOS. Broad Compatibility - Thunderbolt, USB-C, USB 3.0 to HDMI Adapter for Dual Monitors 1920x1080 @60Hz, SMI Driver Required

works well. basically "plug and play. I do worry that the cord section for the B adaptor will break. it is attached at the same place you hold the cord to plug it into the laptop. Since the laptop travels, the cord is frequently plugged and unplugged so if you are not careful the "B" adapter has extra pressure on it while plugging in the "C" adapter.

works perfectly. Only feedback that I have is the issue with watching netflix, disney + or hulu. The video go black due to High-bandwidth Digital Content Protection. But quick fix is to goto chrome or brave browser settings and disable "Use graphics acceleration when available" When you do this the videos should start working.

We bought this to connect two external monitors to both an M1 Mac and a Windows laptop. You do need to install a software driver, but once that’s done it works perfectly. No glitches, no lag, and both screens run smoothly. For the price, I think it’s absolutely worth it.

The adapter works well for connecting two monitors, though the connection is somewhat sensitive to touch and the equipment tends to heat up after about an hour of use.

So I found a driver from SiliconMotion that says it supports Ubuntu 20.04 (and mentions Xorg specifically at the end of the install cycle reboot screen), but I still only see 3 screens in the Cinnamon desktop from the Intel integrated graphics card after reboot. HOWEVER: when I log into a Wayland session, the USB display does show 5 unique displays. I have one monitor capable of 2560x1440, But it's plugged into the integrated adapter which doesn't support above FHD. So all 5 are at FHD. But I fully expect this device to work at higher resolution on that monitor whenever I get around to untangling the mess behind the desk. Note that I previously had a PCI graphics card that had the same problem... generic driver installed successfully, then the additional screens won't show in X, but they do show up in Wayland, so it's probably working in X, just my specific variant of ubuntu (not official release) or all the messing around with X config i've done over the last 5 years is the root cause that it isn't supporting more than 3 screens, or more hardware attached after initial install... But this does confirm that at least with a wayland session, this product does work with linux! Now Wayland on ubuntu 20.04 is still not quite production worthy... but I've read that later ubuntu 22.04 and 24.04, Wayland runs better. I still have a couple things that work for me in 20.04 that I haven't confirmed will continue to work after an OS upgrade (without switching from 1 time licenses to monthly maintenance... but this is way off topic.) Total time to see pixels on screen <1 hour. The driver I'm using can be obtained from siliconmotion (dot) com/downloads (as of 19 May 2025.)

Great price and worked well for about 45 days -- just long enough to get me outside the return window. Now it cuts out/loses connection at least one time per session. If I just wait for it to reconnect, my mouse lags, and basic navigation doesn't work. I have to unplug the adapter from my computer and reconnect. It's a waste of time and money. Pay more for a better one!!!

Was easy to setup and supports dual monitors once the driver/application is installed and configured.

The Plugable Dual Monitor Adapter is a wonderful connector. It works beautifully on my MacBook Pro laptop by connecting two external monitors. The adaptor has two HDMI ports and can be connected either directly to the laptop or to another connector, if necessary. You quickly and effectively have three independent monitors (including the laptop's monitor), which makes work with various files so much easier. The key, however, is the technical support Plugable offers. After using my adapter for three months, it "appeared" to have stopped working. I contacted customer support and immediately received a response offering to replace the unit by providing a serial number. I received a brand new unit two days later. As it happens, the problem was not the connector, and once I reloaded a program and rebooted my computer, I found out the original unit was working perfectly. When I notified Plugable and offered to return the unit, they kindly suggested I keep it for future needs or gift it to a friend. This company provides "above and beyond" support, and its team members are exceptionally courteous. From now on, I will always purchase docks, connectors, and adapters from Plugable. They make products that last and support them for life. Thank you!

Working as required to be .. extended screens for multiple monitors ..

これを使って、グラボを使うことなく4画面にすることができました。順調に動いています。

Worked perfectly. I can now use an extended monitor and an overhead projector.

Tengo un monitor conectado al puerto HDMI de una HP Laptop 15t-dy200 y queria conectar otro monitor mas y este adaptador fue la solucion, ahora tengo los dos monitores y va bastante bien para mi trabajo del dia a dia.

Used this to connect a HP laptop to a pair of monitors. it did what the hp dockong station couldn't do by using available ports.
