I recently own a DJI Mavic Mini. Can I display the live image of my drone on a laptop or external screen?
Should actually go. You can transfer your cell phone screen to the screen of your laptop. Then you can simply connect the cell phone to the drone and then mirror the cell phone screen to the laptop.
If you want to flip the screen onto a monitor, it's best to take a Chromecast or something
How do I best mirror my cell phone with the laptop?
It's a bit complicated to explain. Google the best time:

There are some instructions.
The first one looks pretty good:

But also gives video instructions and so on
