Mid 2015 rMBP + Dell P2715Q resolution not 4k?

[irock101]

Hey,

I got a Dell 4k P2715Q but if I change to a higher resolution than 2560x1440, everything becomes super small and running it at 3840x2160 (real 4k) is smooth as butter, I just need a microscope to see anything on my screen as its all super tiny.

Is there some sort of zoom or any other way I can run 3480x2160 while keeping the icons and text the same size as in 2560x1440?

Right now it's the same resolution as the Thunderbolt display, just non glossy and looks a bit more sharp but I would really like to run the full 4k resolution.

Any help?

Go to System Preferences>Displays, in there you will see two radio buttons saying "Best for display" and "Scaled." Select the "Scaled" radio button and it will bring up a series of scaled resolutions one of which will be "looks like 2560x1440." When that option is selected the GPU renders the desktop at 5120x2880 (twice 2560x1440) and down-samples that image to 3840x2160. That is how the HIDPI modes work in OS X.

It works very well and looks fantastic. This is the exact setup I use (actually the P2415Q).

Hey Patcell, thats exactly what I am using, but I'd prefer to have the real 3480x2160 while scaling the actual text / icons etc. It works perfectly in Windows 10 but not in OSX.

Okay, I'm lost then... Sorry. As far as I know, that menu is your only option in OS X. I'm not sure I am following what exactly you are looking to do... You want to run at 3840x2160, but with text and icons scaled up? That is exactly what the HIDPI mode does in my understanding. The OS is aware when it is displaying an image or video and will show that at native resolution without scaling.

Doesn't work that way in OS X. You draw at 2x what you want and then scale down

Windows separate scales text, OSX does not.
