Big/Small H
The Letter H pattern is a screen filled with a series of large capital “H”
characters moving vertically up the screen. This is a basic test to confirm
motion detail. There are 2 variations: Large “H” characters and small “H”
characters.
38. Line On/Off-H
The Line On/Off-H pattern generates an alternating pattern of single-
pixel horizontal white lines. This pattern can be used to analyse the
vertical pixel resolution of your display. If the output appears to have
mosaic patterns, or appears to be a solid gray field, then it is possible
that your display does not fully support the resolution you are currently
sending to it.
39. Line On/Off-V (2 variations)
White & Black Lines Red & Green Lines
(Not supported in 4K)

resolution of your display. If the output appears to have mosaic patterns,
or appears to be a solid field (grey, white or black), then it is possible
that your display does not fully support the resolution you are currently
sending to it. There are 2 variations: alternating white & black lines and
alternating red and green lines.
