Hey @supersoul, I don’t think you got 4k 144hz because look at the first line in your photo, it shows “Resolution: 3840*2160@60hz”, I got the 0.8m thunderbolt 3 cable to connect my 16inch mbp with spectrum, with the same OSD setting you have, and I only got 60hz.
Yet with the type C to dp cable I can get 4k 144hz.
Hello guys, here is my situation, for your reference:
My laptop is MacBook Pro 16(intel chip), running catalina. I can run 4k@144hz via a type c to dp cable, yet can only get 4k@60hz(with OSD setting USB2.0&4k@144hz) and 4k@30hz(with OSD setting USB3.0&4k@60hz) via Apple’s 0.8m thunderbolt cable.
What really annoying me is that in windows 10 I can get 4k@144hz via Apple’s 0.8m thunderbolt cable, so I think this is just the software reason of macOS, I don’t know if Apple will fix it in the future since they will transfer to ARM chip. I really hate this kind of situation, I was the user of Lumia 900, which abandent by Microsoft once.
And I found that many apps can only run at 60hz even the system is running at 144hz, for instance, the Music app. Photos and Finder app can fully run at 144hz. Safari and Chrome can run at 144hz but they will down to 60hz when scroll web page. I think this is because of Catalina, which is released at 2019, there is no a lot of 4k 144hz screen back then.
So what I am doing now is making a Time Machine and try to update to Big Sur or Monterey to see what I can get, if it ends bad, back to Catalina. Maybe the ultimate solution is to get an ARM Mac, so sad… I really like the feeling of a high refresh rate on a high resolution screen.
