I have tried connecting 2 external monitors with this adapter but only one works. I have tried HDMI, display cable and VGA cable, only one works depending on priorities set. Tried playing with USB-C BIOS settings but does not make any difference. Have connected the adapter to HP Z Book Fury 15 G7 and HP ProBook 440 G7. Belkin website says its only compatible with Mac but pbtech say its compatible with mac and windows
