Maximum Cable Distances; Internal Settings - Extron electronics UHD4K 101 Setup Manual

Maximum Cable Distances

The maximum cable distance depends on resolution, frequency, and, for PC resolutions, the power of the graphics card
(when powered by the source). When the source is a PC, Extron recommends the UHD4K 101 be powered by an external
power supply.

Internal Settings

ATTENTION:
Use electrostatic discharge (ESD) precautions (be electrically grounded) when making connections.

Under most conditions, the UHD4K 101 works without adjustments. However, the quality of the image displayed may be
affected by a combination of the source, display, and cable length. If so, use the three sets of internal jumper switches to
adjust DDC buffer, Equalization (EQ), and Pre-emphasis.
Remove the cover of the unit, as described in the UHD4K 101 User Guide.

In that orientation, the EQ jumpers are furthest from you and the Pre-emphasis jumpers are closest to you.
Set the jumper switches as shown in the table below and replace the cover to the unit.

Function
Adjusting this jumper can improve the image
for some applications with longer cable runs,
image artifacts, or both.
Some applications require that the DDC be
buffered for proper operation.
The Active setting for this jumper (connecting
pins 1 and 2) is required for proper operation
only for applications in which a source has a
weak or no pull up resistor.
