Unable to see the laptop output in the pearl mini

I have connected my laptop to the pearl mini but i am unable to see the output of the laptop

Hello,

Please check on the laptop that it is set to mirror, clone, or duplicate to the second monitor. (As far as the notebook is concerned the HDMI connection here is to a monitor)

If this is in Windows 10 you can check this by right clicking on your desktop then going to display settings. Here under multiple displays set it to duplicate desktop.
