Emulating, Grouping, Synchronising Displays > Emulating, Grouping and Syncing AMD Displays

This guide covers AMD FirePro and Radeon Pro GPUs, for Windows 7 and Windows 10. It covers requirements for even numbers of graphics outputs in rectangular arrangements, within the maximum available pixel width of 16384 px.

Note that the sequence: Emulate > Group > Sync should be followed.

EDID (Extended Display Identification Data):

•is a protocol to allow communication between a device (graphics card) and its connected displays (monitors)

•records display information to the GPU so that it doesn’t have to repeatedly communicate with displays when drawing to them

•maintains the required arrangement on working displays if one (or more) display fails:

oIf the display EDIDs are not emulated (‘spoofed’), and connection between server and a display is broken, then the display arrangement reverts to single display mode, causing media distortion across the working displays, or black output across multiple displays.

oWhen EDID-emulated, working displays maintain the output as if the broken connection (missing display) was still working, minimising disruption to the main output.

Note: it is advisable to keep a note of the relevant IP address of the server so that you can still VNC into the server if you happen to lose visuals – which can happen if an incorrect EDID is applied, such as a resolution forced that was unsupported by the connected display.
