Review: Great value for the money - This is well made and I use it everyday without failure. Well worth the money.
Review: Works adds 4 additional HDMI screens/Win11 - Sure pricey, but not for what it does. USB C out to 4 HDMI screens. I was in need of at least 1 or 2 more HDMI screens above the 4 screens 3 G-Sync on G-Sync 34 inch wide screens. The RTX 3090 Ti board only drives only 4 screens at a time. 2 ports are shared. For FS 2020. This option lets me have up to 8 screens at once. Keep in mind the video out for me is not full screen faster high resolution G-Sync 4K like the three main 34-inch screens are. These are intended for displaying air plane instruments only on smaller touch screens. It was truly plug and play Windows 11. Did exactly what I had hoped it would do. Nice solution when everything else I tried didn't work. Including NOT being able to use the ASUS MB with its built in HDMI/Display Port built video in favor of the RTX 3090 Ti 24 gig monster card that was at least one short for output. Nice product! Beein using Startech hubs for years very happy with this. Can't be sure it just works with Windows 10 (I assume so) but I know it works with Windows 11.
