The Windows API (and other APIs) is buggy with regards to window creations that exceed the dimensions of the monitor. This includes the title bar and the border.
As for why some resolutions aren't supported, that's because your video card does not support the video mode you're trying to render at. The operating system defines which video modes are valid to render and what not, and if the one you input isn't valid then it won't work. This gets trickier once you take into account full screen too. This is why some games have what seems like archaic resolutions, because they're the only supported video modes that your card could handle.
