Hello all,
I have here a MacBookPro9,2 (Macbook Pro 13 Mid 2012) with the latest Monterey in version 12.6. Currently I have the problem that I get no signal on my external monitor via MiniDP. I have tested two different adapters. The integrated display goes black briefly and comes back again.
I have not used the Macbook on an external monitor for a very long time now. I upgraded it with 512GB SSD, 16GB RAM and WiFi BCM943602CS. Everything works great except the external display doesn't like it.
Processor is a 2.5 GHz dual-core Intel Core i5 and accordingly with the integrated GPU Intel HD Graphics 4000 1536 MB.
Additionally, a Windows 10 legacy is installed. Again, the external monitor does not work. I have done a PRAM and SMC reset.
Anyone else have any ideas? Is it because of OpenCore EFI? However, it only boots my macOS and not Windows.
