Question

It’s my first time trying to make anything really interesting in C# and I was trying to make a simple form or game screen where the user could define a custom resolution/screen ratio etc. or to automatically detect the max screen size/ratio and output? its my first game, so I was wondering if it was possible or if there would be any major issues with such, rather than just setting it to 1366×768 (the resolution of all of my computers).
Thanks in advance for any assistance.

You could enumerate through the default GraphicAdapter’s DisplayModeCollection property to find the DisplayMode with the max width/height/aspect ratio.

Something like:

GraphicsAdapter defaultAdapter = GraphicsAdapter.DefaultAdapter;
DisplayMode maxMode = defaultAdapter.DisplayModeCollection[0];
foreach (DisplayMode enumeratedDisplay in defaultAdapter.DisplayModeCollection)
{
    //Test enumeratedDisplay against maxMode, setting maxMode to enumeratedDisplay if enumeratedDisplay is better
}

Maybe there’s a better way, but that’s certainly one way you could find the max.

Or, you could take the same DisplayModeCollection and populate a comboBox of sorts or a list, letting the user choose for themselves.

My apologies if the above code doesn’t work in that exact form. I can’t test it where I am currently
