7. Visually check the monitor’s performance by looking for streaking, fluttering and
shadows.
8. The spatial resolution and aliasing of the monitor are considered to be within
acceptable limits if the high contrast bar patterns in the test image can be seen
as patterns of white and black pairs. To use the pattern, inspect the 6 squares
filled with varying widths of alternating black/white horizontal and vertical lines in
each corner (see Figure 10) of the image as well as in the very center. You should
be able to differentiate all the lines, from wide to narrow (6 pixels, 4 pixels, and
2 pixels) both horizontally and vertically.
