Hi
To run on that high a resolution you may want to change the settings for everything.
Right click on the desktop and select Personalize.
Then select Display.
Now you will see the option to change the size of items.
You can use the custom settings to set the size of your display to anything you want, but I've used 135% on my 27" monitor for years.
On the retina display you may need to go higher then that.
Try 150% and see what it looks like.
You can also select options to change the size of several items individually.
I have the type under Icons set to 12 pt instead of the default 9.
