Thanks, that's helpful. I ordered my MBP but don't have it yet so I'm just having to go by what I read as I research monitors. Here is the issue I'm concerned about, from the bjango article:
"However, display scaling comes with some significant caveats, including a blurrier picture, shimmering when scrolling, moiré patterns, worse GPU performance, and worse battery life if you’re using a laptop. Display scaling also undoes dithering, which can mean gradients aren’t as smooth. With those issues in mind, it’s far, far better to run macOS at the pixel density it was designed for."
Have you noticed any of that?
