Can only use to mirror screen - not extend desktop & it has to run through a browser window.

It's just a tool to mirror your screen to any other device via web. It happens that if you have a virtual second monitor (HDMI dummy) you can share that as your second monitor.

Very old but still OK if you want to mirror the display. There are comments regarding extending the desktop, but it seems to be complicated.
