I want to extend the Windows desktop on my laptop onto two external monitors (total of three separate desktop displays), as shown in this video: https://www.youtube.com/watch?v=Ei58JE63jcw
In that video, the laptop had a VGA output and USB ports. The author connected one VGA monitor to the VGA port and used a USB to VGA adapter to connect the other monitor.
I have two VGA monitors, but the laptop's only video output is an HDMI port. I tried to replicate the setup in the video using an HDMI to VGA splitter and a USB 3.0 to VGA adapter. It didn't work.
The laptop is an HP Envy K203TX, which has Nvidia GTX 850m graphics. How can I connect my two VGA monitors to the laptop given the laptop's available ports?
