Operation

Miscellaneous: Select Miscellaneous from the Service menu to set the following options:

•Language: Select Language from the Miscellaneous menu and press the up- or down-arrows to select the OSD Language (English, Français, Deutsch, Italiano, Español, Svenska, Traditional Chinese, Simplified Chinese, Português or Russian).

•OSD Timer: Select OSD Timer from the Miscellaneous menu to set the OSD Timer, which controls how long the menus remain on-screen after selecting them. Select from 5 to 60 seconds, in one-second increments. Or, set the timer to 0 (disabled) if you want the menus to remain on-screen indefinitely.

•OSD Messages: When you select a new aspect ratio, input source or memory preset, the DHD Controller briefly displays an on-screen message confirming your new selection. To prevent the display of these messages, select OSD Messages from the Miscellaneous menu to and set it to Off.

•Blank Screen Color: Select Blank Screen Color from the Miscellaneous menu to select the color that appears when no incoming signal is present. The range is from 0 to 255 inclusive for each color component (red, green and blue).

•Sidebar Color: Select Sidebar Color from the Miscellaneous menu to change the color of the inactive image area. The range is from 0 to 255 inclusive for each color component (red, green and blue). The inactive image area is on either side of the active image area when using the 4:3 aspect ratio.

•Film Mode: Use Film Mode to smooth out moving images from interlaced, standard-definition (SD) sources. In most cases, the DHD Controller detects the proper “pull-down” rate and vertical frequency. However, if your source is jittery and/or tearing you may want to enable Film Mode to ensure stable processing for that source.

•CUE (Chroma Upsampling Error) Correction: Some DVD players use MPEG decoders that do not correctly “upsample” the 4:2:0 format chroma information on the DVD to the 4:2:2 or 4:4:4 format required by the video encoder of the display device.

This so-called “chroma bug” sometimes causes streaky or spiky horizontal lines running through the chroma channel. It is most noticeable in static, interlaced scenes and on diagonal edges (especially red ones). Set CUE to On to correct this issue.

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 256 mV).

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