3 Overview

The Kramer VA-1Hs UXGA Sync Shifter is a high-performance sync delay
corrector that can be used for any computer graphics video signal from
VGA to UXGA.

When sending a computer graphics video signal from a PC to a monitor via
a long-distance display cable, the delay between the picture information and
the sync may cause a horizontal shift on the display. The VA-1Hs
compensates by shifting the sync accordingly, so that the picture is properly
displayed.

To achieve the best performance:

• Use only good quality connection cables1 to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low-quality cables).

• Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VA-1Hs
away from moisture, excessive sunlight and dust
