2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.

Overview

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 cables1to 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

to center the picture. Depending on the resolution, the image can be shifted
up to about 1/3 of the screen in either direction.
Note: To increase the correction speed, press and hold the SHIFT button for
more than 3 seconds.
3. The setting is saved in non-volatile memory 5 seconds after the last
press/correction.
4. When the VA-1Hs is turned OFF and ON after a correction is made, the
ON button lights weakly to indicate a stored value.

1. Unplug and replug the power supply to turn the unit OFF and ON.
2. Press the left and right SHIFT buttons simultaneously for a short time.
3. When the ON button lights brightly, the operation was successful.
4. Unplug and replug the unit again to resume normal operation.
