I'm having a rather strange issue. When I opened my 13-inch 2020 MacBook Pro, right out the box everything seemed rather small. I went into the display settings and noticed the display setting was set to the "default." However, poking a bit further into this, I saw that the "default" software resolution was being recognized as 1440x900, which corresponds to a 2880x1800 panel @2x. This happens to be the panel resolution of the 15-inch MacBook Pro.
However, my MacBook is the 13-inch variant, which has a panel resolution of 2560x1600. The software resolution should as a result be displaying 1280x800 as default, as that's exactly half of the panel's 2560x1600 native resolution.
I checked on my late 2012 13" Retina MacBook Pro (which has the same resolution display panel resolution and size), and it correctly identifies the default software resolution as 1280x800.
I was having some display issues related to True Tone being intermittently enabled/disabled, so I called Apple Support. I brought up this issue and escalated it to a senior advisor. I tried to show these numbers to him, but he simply stated that the default is "scaled higher than the panel supports since customers complain about text being too small." Which seems to be the opposite of my issue, since everything appeared smaller than it should be.
I reset my NVRAM, but these issues still occur.
Is my display panel faulty, communicating to the OS that it's a 15-inch panel instead of a 13-inch one? Could this possibly be related to the True Tone issues that I'm having?
