c# only draws on partially of the screen

I'm trying to draw on my screen with c# but it only seems to draw e few pixels. Also when I log



   Console.WriteLine(Screen.PrimaryScreen.Bounds.Width);
Console.WriteLine(Screen.PrimaryScreen.Bounds.Height);


It loggs: 1620, 1080 which is half my screen size...



Here is my code with which I'm trying to draw:



 [DllImport("User32.dll")]
public static extern IntPtr GetDC(IntPtr hwnd);
[DllImport("User32.dll")]
public static extern void ReleaseDC(IntPtr hwnd, IntPtr dc);

static void Main(string args) {
Console.WriteLine(Screen.PrimaryScreen.Bounds.Width);
Console.WriteLine(Screen.PrimaryScreen.Bounds.Height);

IntPtr desktopPtr = GetDC(IntPtr.Zero);
Graphics g = Graphics.FromHdc(desktopPtr);
SolidBrush b = new SolidBrush(Color.White);
g.FillRectangle(b, new Rectangle(0, 0, 16000, 16000));
}


Hope someone can help me, Elias :)

  • Are you possibly using display scaling (HiDPI) in Windows? This sounds like your program isn't HiDPI aware and gets confused there.

  • Yes, my scaling was set to 200% by default which would exactly fit the 1/2 of the resolution... and how am I going to fix that now?

  • stackoverflow.com/questions/23551112/… seems relevant. (There's also stackoverflow.com/questions/4075802/… if that doesn't do the trick.)

  • @AKX Hm I've already seen those but I don't have any forms... just the main function and some threads... I'm not sure what to do :(

  • The first linked answer should be relevant even without threads, as you're using GDI/GDIplus to draw.
