Have had the 5K display now for just over a week. I'm using it with a new 15" MBP TB as an external monitor with the clamshell closed. Seems nice enough but I do have a couple of questions.
First is the screen resolution. The advertising states 5120x2880 resolution but nowhere can I find a setting to achieve such a resolution. I'm not arguing the merits of whether actually wants their display set to 5120x2880, just that I don't see where it's actually available. The highest setting I can find is 3200x1800. The
Apple support page also lists the available resolution as 5120x2880 @ 60Hz. I called Apple support and logged a case about this a week ago... no response as of yet.
Additionally, I don't see anywhere that 60Hz is actually being used. Where does one find such a setting?
Even though page 9 of the
owner's manual shows a diagram with an ambient light sensor, there is no auto-brightness available in the display settings. This is particularly annoying, as I have a window right next to my desk. If I manually adjust during the day, then come back in the wee hours of the morning, I get dazzled by the over-bright screen. For the $$$ spent, this should have been available.
