Review on StarTech.Com USB 3.0 Or USB-C Dual HDMI Adapter For Windows & MacOS, 2X HDMI Displays (4K30Hz/1080P), Integrated USB-A To C Dongle, 4In Cable (107B-USB-HDMI) by Ronald Wheeler

I was able to add two 28 inch monitors to my laptop computer with this device. It works great! I was surprised that I could also watch a youtube video on the 28 inch monitors, because I thought the frame rate would be too slow. I didn't buy this watch videos, but rather to extend my visible workspace on my computer. I can have an editor open on my one monitor, and excel spreadsheet on the other, and then have my work email open on the laptop monitor and easily see all my tasks at once. It makes work easier than constantly opening/minimizing windows. The only downside/issue I had, was that the System Tray icon never appears in Windows 10. I suspect Windows 10 is doing something to prevent it from showing, but it didn't matter, because you can still view the Monitor/Display properties through the Windows 10 control panel, and then define displays 1 thru 3, and then orient them in the positions you want. So it works without the System Tray icon, but someone not familiar with the control panel in Windows 10 might have a problem finding the settings and getting it to work properly.
