Question: 3840x2160 monitor

[Mobhack]

The SAL errors occur when you try to use a resolution the monitor cannot handle.

You should use windowed mode at desktop resolution.

Full-screen (256 colour) mode is only there as a legacy from DOS and XP days, the 256 colour mode it uses is no longer the fastest video mode, as modern graphics cards have to emulate it (if they support it at all).

To support a smaller screen size using desktop resolution:
- Use the windows preferences to switch to the smaller screen size
- Now start the game in windowed mode at desktop resolution and it will now use the smaller size windows is set at (i.e. the windows desktop size)
- Once finished playing, reset windows to the original size.
