HDTV Support

Use HDTV Support when your CRT or DFP display device supports one
or more HDTV modes that are not initially listed in the Displays Manager
due to an incomplete EDID (Extended Display Identification Data).
Selecting one or both of the HDTV modes adds them to the Force button
located in the Displays Manager when the associated display is selected.
If you have both CRT and DFP display devices and want both to support
HDTV, you select both the Add 720p and Add 1080i check boxes in the
corresponding HDTV Support pages.
The following formats and refresh rates are fully supported supported:
• NTSC
• PAL
• SECAM
WARNING!: Forcing a display mode that exceeds its EDID
limits may result in permanent damage to your display!
