The clouding effect must not rise to disturbing levels in anywhere
of the screen with luminance setting from 15 to contrast 100%.
During mode change or unstable input signal, the video will be
blanking for 1s to 2s, no switching behaviour is visible.
Not allowed.
No on-screen interference can be seen, when two monitors are
placed side by side (distance: 30cm) and operate in different
modes.
