Scaled 1080p while AirPlay mirroring
I have a 2012 MacBook Air (11-inch) and noticed that if using AirPlay mirroring to an ATV2, if I choose the resolution that is "best for this computer," the display on my MacBook screen increases to a scaled 1080p. If I choose the other option, it changes to a scaled resolution smaller than the native. Even stranger, if I then turn off AirPlay, my MacBook stays on the scaled 1080p resolution, even though this isn't an available option in the display preferences. Anybody else having this issue? I'm also having some issues with the display brightness and keyboard backlight, so I think an SMC rest might be in order anyway.
While the text is quite small and things are a little fuzzy, I kind of like having such a dense resolution on my 11-imch screen. I almost wish this were an actual option.
