I have an older iPad Model ME400LL/A running on software version 10.3.4 (the last uploadable version to this old iPad) and asking if it will mirror the display from my MPB M1, or as I suspect, no as its too old???
iPad, iOS 10
Your iPad does not support external video input - and cannot be used as a simple external display for HDMI, VGA or composite video sources.
An iPad can be used with a compatible Mac to extend the Mac display to the iPad using the Catalina/iPadOS Sidecar feature.
Use iPad as a second display for your Mac – Apple Support
However, your iPad4 is far too old to support Sidecar.
