NOTE: **Discrete only
mode or “Special
Graphics Mode”.
NOTE: If higher resolution monitors are used, the Intel Graphics driver will make a judgement based on monitor specifications
and display configurations. Some resolutions may not be supported and so will be removed from the Intel Graphics Media Control
Panel.
NOTE: Resolution support is also dependent on the monitor’s Extended Display Identification Data (EDID) resolution.
NOTE: The 5K resolution support is only available in either of these conditions:
1 With discrete graphics mode only, or special graphics mode, or
2 *** Using the Thunderbolt 3 Type–C to a dual DisplayPort adapter.
NOTE: ** Configuration supported with AMD and Nvidia in discrete-only mode or special-graphics mode. These modes are listed
in the BIOS for the Dell Precision 7730/7530 systems and will require disabling switchable graphics for discrete-only mode or
enabling special-graphics mode when Switchable is enabled. If the system does not have these options in the BIOS, then 4
monitors are NOT supported.
