Third and fourth display must be daisy-chained through the DisplayPort (DP) 1.4 port using Multi-Stream Transport (MST)
monitors connected to the DP 1.4 port. All DisplayPort (DP) connected monitors should have Display Stream Compression
(DSC) support. If non-DSC monitors are used, then maximum resolution (HD: 1280 x 720) is the same as HBR3 non-DSC
(12.9Gbps) offerings.
***
This resolution is supported when using HDMI 2.1 monitor with Fixed Rate Link support for higher video resolution and
refresh rate. An HDMI 2.1 cable is also required for this display resolution.
*** *
Quad display setup functions only in LCD off mode.
Important
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.
