I have selected what the web service tells me were my current resolution for the work PC, I do not have a way to verify if that is actually true… My boss says that were a 4k screen…
Anyway, I want also to add, that I really like to play a bit with portait orientation. Though at home I can’t as my primary screen is a laptop and my secondaries stand is not tall enough for remounting the screen in portrait. At the office my internal IT refuses to change the system settings for screen orientation as they fear, that no one else would be able to use the workstation then.
