    monitor: Set MINIMUM_LOGICAL_HEIGHT to 480
    
    Using 800x600 as minimum logical size is very 4:3 thinking, while a lot of
    modern devices are 16:9. The specific reason for this commit is to allow
    1.5 scaling at mini-laptops (clamshell devices) with e.g. a 5.5"
    1280x720 screen. Given that this device has a keyboard, one obviously
    is not holding it very close to ones eyes and at 220 dpi that means the text
    is too small at scale 1.0. For one real world example of such a device see:
