The ‘Horizontal Lines’ test pattern should appear as one pixel tall black and white rows. If you see
any irregular pattern(s) in the image then you know that the display is scaling the signal vertically.
To override the internal scaling, adjust the vertical size of the image to see if the test pattern can be
displayed correctly.

The ‘Judder’ test pattern displays a bar that bounces back and forth at the chosen output frequency
selected in the ‘framerate’ parameter. When this test pattern is displayed correctly, the bar moves
smoothly across the screen and bounces from side to side. When this pattern is displayed incorrectly,
this bar may ‘tear’ as it moves across the screen. To adjust the framerate conversion, go to the ‘Out-
put Setup’ menu.

The iScan VP50 has several test patterns to assist in the setup of your display. Adjustments should
be made on your display, not on the iScan, to correctly setup your iScan and display. The ‘Bright-
ness/Contrast’ test pattern will assist you in setting up both the brightness (black level) and contrast
(white level) of your display. The ‘Brightness/Contrast’ test pattern is composed of 4 quarter-screen
blocks. Two of the blocks have a background level of standard black and the other two blocks have
a background level of standard white. Embedded in the black blocks are 3 bars. One is 4 IRE below
black (blacker-than-black), one is 1 IRE above black, and the third is 2 IRE above black. Embedded in
the white blocks are 3 bars. One is 1 IRE above white (whiter-then-white), one is 1 IRE below white,
and the third is 2 IRE below white. The bottom two blocks differ slightly from these levels. For the bot-
tom two blocks, the blacker-than-black is at the lowest possible luma level and the whiter-than-white
bar is at the highest possible luma level. When the brightness and contrast are adjusted correctly, you
should be able to see the 1 IRE and 2 IRE above black bars on the black background and the 1 IRE and
2 IRE below white bars should be visible on the white background. When the brightness is adjusted
