Important
NOTE:
HDMI 2.0 and MFDP (Multi-Function DisplayPort) Type-C ports on the back of are toggled. HDMI 2.0 and MFDP
Type-C cannot support dual monitors simultaneously. Only one of these ports can be used at a time.
NOTE:
If higher resolution monitors are used, the Graphics driver makes a judgment based on monitor specifications and
display configurations. Some resolutions may not be supported and so will be removed from the Windows Display Control
Panel.
NOTE:
Linux operating system is unable to physically turn-off built-in display, the external display numbers will be one less
than the display numbers listed in above tables.
NOTE:
Resolution support is also dependent on the monitor’s Extended Display Identification Data (EDID) resolution.
