Want to use an iPad as a secondary Mac display? Apple built that capability, called Sidecar, into macOS Catalina for those using newer Macs and iPads. It’s free, unlike third-party alternatives. Julio Ojeda-Zapata liked Sidecar enough to continue using it, but he also found glitches.

If you want to use Sidecar with an unsupported Mac, it may be possible (if slow).
