No HighDPI Mode with GTX750Ti and Dell 4K Monitor

[MadBlue]

Hello!

I managed to install MacOS X 10.11 on my old ThinkCentre M91p.
GraphicsCard is a GTX750TI and I'm using the news nVidia WebDrivers.
I connected my 4K Dell Screen via DisplayPort and it's running fine. (Can Select 38xxer Resolution and 60Hz refresh)

But I don't get the HiDPI/Retina Slider in the MaxOS Settings. That's a bit of a shame because now I have to lower the System Resolution to get everything git enough to be fine.

With my MacBook 15 Retina it's different. There I can just use the Retina-Slide to make everything bigger at the native Screen Resolution.

Any ideas to solve this?

Greetings and thanks for helping!

Normally I think on System Preferences / Display it offers resolution Default for display or Scaled, and if you pick Scaled, you get the retina modes to pick from (sometimes with icons, sometimes in a list). In some cases if you set it to Default for display and hold down Option while you select Scaled, you get still more choices.

What does it offer you when you pick Scaled?

Thank you for answering.

Sorry, maybe I did not make clear what I want to achieve.

On my Custom Mac:
-I open the system settings
-I open display setting
-I select the second radio Button named 'scaled'
-I get a List of resolutions up from the max resolution down to 1280*something.

What I whant is the same behavios like on my MacBook Retina.-I open the system settings
-I open display setting
-I select the second radio Button named 'scaled'
-I get slider where I can define the DPI density from very low to very high.
-Would like to get this to work on my CustomMac to.

Greetings,
Sören

I've never used a MacBook Retina, and I haven't seen the interface you describe before. I've seen one that shows 4-5 icons and one that shows a list, but never one that shows a slider. Perhaps it's unique to the MacBook Retina?

This might help :

In Terminal :

sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true

Restart
System Preferences - Displays : Hold down option key and click on the scaled option.
Some are marked as 'low resolution'. If you select one of those options the
desktop will be proportioned for that resolution but will be rendered in HiDPI mode, so it will appear sharper than normal.

Hi,

yes you are right, there are 5 options, not an actual slider. (But in my head, it looked kind of slidish )

So I'm looking for this kind of menu:


But I'm stuck with this here:

following you advice brought me to this:

Never ever saw this before

EDIT:
I think I made a mistake.
Cause I knew the list-menu from my non 4K Display, I thought it would reduce the system Resolution. But indeed it seems to HiDPI-scale the image. Just when I select the (new) "low resolution" options, it really lowers the system resolution. (And image is washed out)

In that case: Very sorry for stealing your time guys.
Will check this tomorrow... cause over here it's already 1:45 AM... :X
