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.
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.
If the Display Port Data Rate is HBR2, then, the maximum resolution that Linux supports is 8192 x 8192 (counted with
built-in display plus external display.
Resolution support is also dependent on the monitor’s Extended Display Identification Data (EDID) resolution.
