34 test patterns

pluge 2

The cross hatch included in the DVD32FLR is a multi-purpose test-pattern which will allow adjustment of contrast and sharpness.

The test pattern includes a series of black lines on a white background. Adjust the contrast, after having set the black level correctly, so that white becomes solid without blurring into the black lines and without turning the black lines grey.

Cross-check your setting by turning back to the PLUGE 2 test-pattern and check that the bright white field (PLUGE 2) isn't blurred into the black background. Some display devices allow a very high contrast setting without blurring, others will always blur.

On some display devices the black lines will have a second or even multiple lines beside them, usually shown in a light grey. They can be caused by many reasons, for example poor cables between the DVD player and the display device or - usually only available in NTSC - a wrongly adjusted sharpness control. Use good cables, such as our S-Video or digital cable (for Composite or Component) and turn the sharpness right down to remove these artifacts. Frequently you might find that you cannot remove those extra lines completely.

colour

The colour test-pattern allows you to adjust Colour (and Tint in NTSC)(1). Adjust those two parameters until yellow looks yellow (without including too much red) and Red is not over- saturated. Your might use filters, available from specialist suppliers, which will allow you to more objectively adjust colour.
