We became available Godot 2.1 RC1 link
One of the expected changes is the support for HIDPI screens in the Godot editor.

Dear developers, huge, huge... extremely huge to you thanks! :-)

In connection with this change becoming a pressing issue:
How to support HIDPI in your project?

I'm developing a 3D game which works only in full screen mode. It incorporated the switch from 1280x720 to 3840x2160. How to perform a theme, icons, fonts, whatever they are displayed correctly in all screen resolutions? What are the necessary settings?

Project Settings > Display > Stretch mode > 2d
Is this setting not enough?

The problem is that this setting doesn't let you provide your own hi-DPI graphics for theme items and other sprites, so everything is either pixelated or blurry when upscaled.

I resolved the issue with support for screens of different densities. In this matter, I did not rely on the mechanism of Godot HIDPI. I have a global script which switches the resolution viewport, there it is possible to obtain data on the current screen resolution.

Next, I drew in SVG format elements of a theme and exported it to a raster for three different size theme: "low density", "medium density" and "high density".

Next, I added in script the variable, in which the loaded theme as a resource. I update this variable automatically when you switch screen resolutions.

And last... in:

func _ready():

all scenes interface I prescribed the application of themes from the variable global script.

This enough ;-)

An alternative to changing the stretch mode is to determine the scaleFactor.

var displaySize = Vector2(Globals.get("display/width"), Globals.get("display/height"))
var scaleFactor = OS.get_window_size() / displaySize
OS.set_window_size(displaySize / scaleFactor)

You shouldn't set the window size, I just added it so you could see the effect. Instead, you can use scaleFactor to determine what resources you should load. It's a Vector2 which returns (2, 2) on my Retina display. So in this case, I would load resources that are twice as big.
