Operation

Sync Threshold: Select Sync Threshold to adjust the threshold at which negative pulses on the component video green/luma channel are interpreted to be sync pulses.

Sync Threshold adjustment is occasionally necessary when a DVD player or HDTV source signal drops “below black” (for example, during scenes with explosions or when subtitles are present) and causes the projector to temporarily lose sync. If the sync level from the source is persistently too low, the display device won’t sync with the source at all.

The range is from 0 (approximately 60 millivolts (mV)) to 15 (approximately 300 mV).

HDMI: Select HDMI from the Service menu to set the following options affecting communication between HDMI sources, the DHD Controller and the D-73d.

•HDMI EDID Extension: Extended display identification data (EDID) is a data structure provided by a display device to describe its capabilities to a graphics card. It is what enables a modern personal computer to know what kind of monitor is connected.

Some modern display devices provide more information via EDID than others, in the form of “extensions.” Some computer graphics cards do recognize or properly interpret this extended EDID information.

Select HDMI EDID Extension from the HDMI menu to specify whether or not the EDID extensions from the display device are passed through to the 3Dimension Processor and to the sources connected to the HDMI 1, HDMI 2, HDMI 3 or HDMI 4 inputs. By default, the extensions are on. Change these settings only if HDMI EDID incompatibility issues arise.

•Audio Format: Select Audio Format from the HDMI menu to choose an option for routing the audio signal from an HDMI source. With the D-73d, the recommended setting is HDMI Out (Audio Only). (This is also the default setting.)

•CEC: This control chooses whether or not the DHD Controller responds to HDMI CEC control messages from a disc player, set-top box or other HDMI source. It also enables or disables communication between the Primary DHD Controller and the 3Dimension Processor.

The default setting is On. For more information about CEC, refer to Using HDMI CEC Messages on page 112.

Caution

Note

Do not set CEC to “Off” unless specifically instructed to do so by Runco Technical Support. If you do, the system will not work properly.

The DHD Controller does not transmit HDMI CEC control messages from the “HDMI Audio Out” connector, regardless of the CEC setting.

•HPD Toggle Rejection: Select HPD Toggle Rejection from the HDMI menu to specify whether or not the DHD Controller ignores extraneous Hot Plug Detect (HPD) signal state changes from a downstream HDMI device (third-party display or audio/video receiver).

The default setting is Off. Set it to On when troubleshooting compatibility issues or to reduce the amount of time needed to lock to an incoming signal.
