using old iMac as a display with newer MacBook Pro

im trying to use a late 2009 2.5" iMac running El Capitan as a display monitor for a 2019 MacBook Pro with the mini display port and hdmi to no avail. I used the target display mode but it wouldn't take. any suggestions?

MacBook Pro 16″, macOS 12.5

You can use that model iMac as a display with certain other Macs, but that model MacBook Pro is not one of them.


Refer to Use your iMac as a display with target display mode - Apple Support.


It's no substitute for TDM but you can use Screen Sharing: Share the screen of another Mac - Apple Support.
