Screen Size

[LeeChard]

When beginning the game I get a screen size setting prompt, I need to make this change. I can't find an option for this.
What is the procedure?

I need some more information since I have never seen this before.
What version of the game are you running? Are you trying to run this in Windowed mode (set in the options dialog)? Are you trying to run this through DXWnd?

Is this a laptop or a desktop with a fancy graphics card?

Win10 Desktop I7 with GTX1660 ti
Not in window
I do not know what DXWnd is

If you want to play full screen you should try running it with DXWnd, it could solve your problem. See this post:
