How to apply a large 4K screen for a monitor for MavicPro2

[Enigmatic51]

I wish to get more see detail and view enhancement. I have a DJI Mavic Pro2 and the cell phone screen is way too small for on the move review like a SAR environment. I have used the IPad application versions, it does alright, but still too small. This screen is for flying from a table of a supported screen in a vehicle. No wifi available like in a home or store...I have seen some chatter about this in the past and it would work with a DJI FPV, but I need Mavic Pro2 applications... Thanks in advance!
