3.3 DDC Support
For best compatibility with source devices (e.g. a PC), an extension device (XRTx in this case) should provide an
appropriate DDC profile with the proper resolution and timing information. This helps ensure best compatibility
with display devices connected at the remote end.
The XRTx supports a simple yet very flexible DDC management scheme:
• The built-in factory-default DDC profile supports a number of standard resolutions and timing information
that is widely compatible with many displays.
• A specific DDC profile can be copied from a particular display and stored inside the XRTx’s non-volatile
memory. This method enables the best possible compatibility with a specific display that would
otherwise not work properly if simply using the factory-default DDC profile.
• Finally, the XRTx supports a “pass-through” mode, where the DDC profile of a locally attached display is
passed directly to the video source. This can be very helpful in diagnosing certain resolution or timing
related display issues, but generally is not used on a permanent basis (though it is safe to do so).
The following table describes DDC support specifications.
