Now before my 2019 Mac Pro strangely died and got replaced with my 2023 Mac Pro M2 Ultra I never had any issues with having Dual Monitors. After a few months of having my awesome 2023 Mac Pro M2 Ultra I had a issue where my Secondary Monitor would flicker on and of so I naturally I assumed it was a loose cable connection or a faulty HDMI etc. So when I realised it wasn't a loose connection I bought a new HDMI and no luck so bought a few more think it was a few faulty HDMI's but no, however the issue slowed down it my Secondary Monitor hardly went off but 2 Operating Systems later the problem gets worse. I often leave my Mac on over night as I often have work in process etc. but I turn off both screens but in the morning sometimes my Mac wont see my Secondary Monitor / TV, at the time I had a odd fix where i turned off and on the HDR setting on the Mac. However that trick stopped working and whenever my Mac doesn't recognise my Secondary Monitor the only way my Mac can see it is if I restart it.
My mate once told me its a common issue so is there a fix to this annoying problem. I've had Dual Monitors on most of my Macs but I've never had this issue so I hope you can help me.
Mac Pro, 15.0
