This call returns information on which features are supported by the ScreenModes module.
Notes
EDID support
If bit 0 is set then it indicates that ScreenModes supports EDID. This includes:
- The ability to load EDID files using *LoadModeFile
- Automatic export of EDID files to Resources:$.Resources.ScreenMode.Monitors.EDID<n> on driver initialisation (where <n> is the GraphicsV driver number)
- Automatic use of EDID-derived modes on boot when the configured MonitorType is set to EDID
However, this does not guarantee that any particular driver / monitor supports the reading of EDID.
