          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.

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.
