Used it to be able to remote access a computer by exporting the display. It simulates an external display so the os assumes there is a local session on. Works perfectly for my headless windows 10 server.
Product title is outright deceptive. Locked the screen size at 800x600 with no ability to change.
According to the description this comes with a dash-mount bracket, it does not. Bought a 10 buck repeater, screen flashed on & off on the vr headset.
