•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.

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.
