Results Explanation
Total shows the total number of pixel errors detected.
The bottom line shows the number of pixels errors
detected per color component.
In this example, the total number of pixel errors is 9, with
9 errors on each of the color components.
In the bottom row, the left value shows the number of
pixels being measured in billions and the right side
shows the number of pixel errors per billion.
Note: When the number of pixel errors becomes very
large, the text “Very high” is displayed in the bottom row
in place of actual values.
In this example, 4.255 billion pixels were measured and
0.88 billion pixel errors were detected.
ERR shows the selected error number and Fr shows the
frame in which the error occurred. The
X and Y values
are the screen coordinates at which the error occurred.
The bottom line shows the measured RGB values.
To step through the errors, press the + and - keys.
In this example, Error 001 occurred in Frame 00000001
at coordinates (44545,0000). The measured RGB val-
ues were R128, G016, B128.
