Custom Resolution with Forced Output

Previously, I was able to use a resolution of 76x59 on my mini screen. I would like to suggest an option, similar to --force 80x24, that would allow forcing a specific resolution (e.g., 80x24) even when using a different default resolution. This would help maintain a consistent display format on smaller screens.

Start by locating the existing --force option handling and the code that determines the display resolution. Define the new forced-resolution option so it can specify a value such as 80x24 independently of the default resolution, then verify that the display keeps that format on smaller screens.
