        Arbitrary viewport dimensions and refresh rates are accepted.

        Known-good presets include:

        For GPU images, recommended presets use one of these resolutions with refresh rates 60, 30, 25, or 10:

        800x600, 960x720, 1024x576, 1024x768, 1152x648, 1200x800, 1280x720, 1368x768, 1440x900, 1600x900, 1920x1080, 1920x1200, 390x844, 360x250, 768x1024, 800x1600.

        Viewports outside this list may exhibit unstable live view or recording behavior.

        If refresh_rate is not provided, it will be automatically determined based on the resolution
