Review on 🔌 CableDeconn Multi-Function DisplayPort to HDMI/DVI/VGA 1080P Adapter Cable with Audio Output - 4-in-1 Converter Supporting Simultaneous Connection of 3 Monitors by Tim Pulse

The description says: CABLEDECONN HDMI/Dvi/Vga 1080P 4-in-1 Multifunctional Displayport Cable Audio Out Adapter Cable Micro USB Male to Female Adapter Support 3 monitors at the same time. However, when I research why I can't use more than one monitor, I find the following; Can the 4 in 1 adapter be connected to three different monitors? That is, this 4-in-1 adapter does not support an active monitor with three different displays, it only supports connecting and setting up one monitor for extended desktop or mirrored displays with the same display. am I missing?
