Older Dell monitor now not working on new Macbook Pro 2019 16"

I was running two Dell external monitors on my early 2015 13" Macbook Pro:

- P2414H via Displayport/Thunderbolt 2 adapter

- SE2717H/HX via HDMI/Thunderbolt 2 adapter

I've upgraded to a 2019 Macbook 16" Pro 8-core i9 running Catalina 10.15.5, and now only the later model SE2717H/HX works.

The older Dell P2414H recognises when I plug it into the Thunderbolt 3 port via Displayport cable (or even the old VGA using an adapter), but immediately after goes to sleep. Any software/driver fixes, or is this monitor too old now for the newer Macbook?

Thanks

Hi Brenden thanks for getting in touch. I spoke to Apple and the assistant looked up the specs of the Apple T3 (USB-C) to T2 adapter and confirmed it is not compatible with the cable. I have since bought a DisplayPort to Thunderbolt 3 single cable and this is now providing the monitor signal correctly. Worth noting. I appreciate your time though.

Regards

Chris
