I you don’t need it, you don’t need it, but I don’t understand the first sentence. Many different displays support DDC, my Philips at home does and the Dells and I think BenQ that we have at the office do too.
I wish my personal was a mac as well, but I had to abandon macs when they abandoned me by not upgrading the mac pro for like a decade then kept me away by later ending support for eGPUs.
