`Makie.primary_resolution()` is [was?] a useful function for setting images to full screen size in GLMakie.

However, after the release of  
Makie v0.19.2

a call to this function generates an error message stating that the function is not found:

`LoadError: UndefVarError: primary_resolution not defined`

Has `Makie.primary_resolution()` been deprecated and, if so, is there a new method available to set images to full screen size without hard-coding the screen dimensions?

OS: Windows 11  
Julia: 1.8.5

Ah sorry, that was considered to be an internal method, which Makie wasn’t using anymore for quite a while, so I removed it.  
I’m not sure I want to bring it back, since it didn’t work very well cross platform…  
Maybe we should add it to GLFW.jl, or you should just add it to your own project.

Thank you for your explanation.

I located the `primary_resolution()` function code in Makie 0.19.1

```julia
const DEFAULT_RESOLUTION = Ref((1920, 1080))

if Sys.iswindows()
    function primary_resolution()
        dc = ccall((:GetDC, :user32), Ptr{Cvoid}, (Ptr{Cvoid},), C_NULL)
        ntuple(2) do i
            Int(ccall((:GetDeviceCaps, :gdi32), Cint, (Ptr{Cvoid}, Cint), dc, (2 - i) + 117))
        end
    end
elseif Sys.isapple()
    const _CoreGraphics = "CoreGraphics.framework/CoreGraphics"
    function primary_resolution()
        dispid = ccall((:CGMainDisplayID, _CoreGraphics), UInt32,())
        height = ccall((:CGDisplayPixelsHigh,_CoreGraphics), Int, (UInt32,), dispid)
        width = ccall((:CGDisplayPixelsWide,_CoreGraphics), Int, (UInt32,), dispid)
        return (width, height)
    end
else
    # TODO implement linux
    primary_resolution() = DEFAULT_RESOLUTION[]
end

```

and have incorporated it into my project.

It works, However, I can see why you have deprecated it.

I suggest that a function with such capability cross-platform be added to GLFW.jl as I think other users besides myself would also find it quite useful.

You can also use a combination of existing functions to make your own version:

```julia
function primary_resolution()
    monitor = GLMakie.GLFW.GetPrimaryMonitor()
    videomode = GLMakie.MonitorProperties(monitor).videomode
    return (videomode.width, videomode.hieght)
end

```

There are reports of this calls not working on remote connections and on headless systems, but if you are not in that situation, it should work fine (plus the `MonitorProperties` can give you additional info, if you would need it).

Your `primary_resolution()` function works well on Windows 11.  
Much appreciated. Thank you.

In the Makie documentation I found a section that refers to  
[GLFW window attributes](https://docs.makie.org/stable/documentation/backends/glmakie/index.html#activation_and_screen_config) including

- `fullscreen = false`: Starts the window in fullscreen

but no example code on how to do this.
