Bought to work with my new 4k monitor and it works very well with 1 display at a time. I don't have two 4k displays, so I can't test if it works (like it says) with this setup. What it doesn't do on Windows is mix 4k and 1080p monitors. Both output in 1080p (it downsizes a 4k monitor). With a second USB adapter, I was able to output data to different screens at the same time. In the 4 display screenshot, #1 is my laptop's main display, #2 is my new 4k display, #3 and #4 are my old ones. Displays 1080p through my old USB adapter. In the 3 display screenshot, #1 is my laptop's main display, #2 is my old 1080p monitor, #3 is my new 4k display but it doesn't support 4k resolution.
