Hi everyone! I have mac mini 2014 and I want to buy 24" 2k(2560 x 1440) monitor.
GPU on MacMini can output 2560 x 1440 at 60Hz and 4k at 24Hz.

Is it possible to enable 1080p HiDpi at 2k monitor? (with the method from the opening post)
Will it be at 60Hz or at 24Hz If I use Mac Mini 2014?
How does it work? MacMini outputs 4k (1080p hidpi) image which would be scaled to 2k resolution at monitor?

@joevt please help

I think 1080p HiDPI should work (I don't have a 2014 Mac mini). You have to make an override file for your display with a scaled resolution of 3840x2160 if it doesn't exist already (it probably exists if it works?).

The 1080p HiDPI mode will draw to a frame buffer that is 3840x2160 and the GPU will scale it down for output to 2560x1440 60Hz to the display. The display does not do the scaling since it's receiving its native resolution from the GPU.

Will it run on 60Hz on a 2014 Mac Mini? In another words can it process 3840x2160 60Hz and output 2560x1440 60Hz?
GPU in 2014 Mac Mini can't output 3840x2160 60Hz

i have moved your posts to macmini section
 
i have moved your posts to macmini section
Why? It doesnt matter where to run hidpi, on a mac or on a hack.
The only difference is that nobody will answer in this section
 
because this is where your post belongs
there is no difference where to discuss hidpi, because it is software method
you do really strange things))
