How to prevent scaling in Windows?

[Przemator]

Hi

My screen resolution is 1920x1080. I am using the scaling of 150% on Windows 7.

This function:

Code: Select all

width, height = love.window.getDesktopDimensions( display )

Returns 1280x720.

In window mode, if I declare window size of 1000x600, it has a size of 1500x900, and everything is stretched, the pixels are not sharp.

How do I disable desktop scaling in a LOVE game? In settings of LOVE.exe, desktop scaling option is grayed out.

Does enabling highdpi mode do anything to help?

Maybe take some screenshots of what it looks like wrong.

High DPI scaling for Windows/Linux is supported in Love2d or more accurately it is not in the underlying library SDL. So you either have to turn off scaling in windows or normal/exclusive fullscreen might give you the full resolution. (With the obvious problem that you're forced to use fullscreen)

Actually SDL's Windows and Linux backends don't currently support high-dpi, unfortunately. Right now there's no real way for love to use the real pixel density of a display in Windows, if global DPI scaling is enabled on the system.

I have googled and I found a workaround. For 64bit applications, the compatibility fields are grayed out. You have to manually add an entry in the Registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
In that key, create a String entry with:
Name = The full path to the .exe of your application
Type = String (REG_SZ)
Data = HIGHDPIAWARE
