                  LAG TEST (1/2)

This test is designed to be used with two displays
conected at the same time. One being a CRT, or a
display with a known lag as reference, and the
other the display to test.

Using a camera, a picture should be taken of both
screens at the same time. The picture will show 
the frame discrepancy between them. 

The circles in the bottom help determine the frame
even when the numbers are blurry.

The #YSega Genesis#Y version of the test can be used
with a #YNomad#Y as the reference display.   #C(cont...)#C
                  LAG TEST (2/2)

You can also chain the output ports of a #YPVM/BVM#Y
to an upscaler and use the CRT as reference, or
split the video signal.
