DVI 201xi Tx • Configuration and Operation
3-7
DVI signals run at very high frequency and are especially
susceptible to bad video connections, too many adapters,
or cables that are too long. To avoid loss of an image or
introduction of image jitter:
The DVI cable on the input to the transmitter or the output •
from the receiver should not exceed 10' (3 m).
Use only cable designed for DVI signals.
•
Limit or avoid the use of adapters, patch panels, or •
couplers with the input DVI cables, the output DVI cables,
and/or the twisted pair cables. Additional links in the
chain will reduce signal integrity and overall cable length
performance.
Always turn on the display before the DVI video source in
•
order for the source to retrieve the DDC from the display.
The source device must be able to obtain EDID information
when it is being powered on, it may not be able to send a video
signal or the signal may have the wrong resolution or refresh
rate.
Ensure that the DDC are configured correctly for the EDID •
source (see pages 3-2 to 3-5).
The source device must be powered on after the display
•
device providing the EDID source has been powered on.
Incorrect color or tint — Ensure that the twisted pair cables are
terminated correctly and to the same standard on both ends of
the cable (see page 2-11).
Display device displays a flashing black or blue screen, snow
or other distortion
— A device that is not HDCP compliant may
be receiving HDCP-encrypted signals.
The DVI 201xi Tx is only compatible with High-Bandwidth
Digital Content Protection (HDCP) signals when the EDID
Minder is disabled. HDCP signals can be passed through to
only one display (remote or local) and only that display will
show the signal correctly.
Signal on local monitor but not on remote display — Check
that both output devices (local and remote) can handle
resolutions equal to or greater than the EDID source.
