Some development users have the need to use multi-screen, Linux VDA default support 2 monitor, resolution 5120x1600, if need to support 3 screen or 4 screen, need to modify the Linux VDA registry key value (maximum support is 9), while modifying the image resolution to adapt to multi-screen display.
First, modify the default support display quantity.
Enter the command:
/opt/citrix/vda/bin/ctxregupdate-k "Hklm/system/currentcontrolset/control/citrix/thinwire"-V "MaxScreenNum"-D 4

Modify the resolution.
The value to be based on customer field demand, the horizontal key value for the display matrix of the horizontal resolution and vertical key values for the display matrix vertical resolution and.
The matrix example is composed of two blocks of 4 monitors at 1960x1080 resolution.
Then horizontal key value: 1960x2=3920; vertical key value: 1080x2=2160.
Modify the horizontal key value,
Enter the command:
/opt/citrix/vda/bin/ctxregupdate-k "Hklm/system/currentcontrolset/control/citrix/thinwire"-V "MaxFbWidth"-D 3920

Modify the vertical key value,
Enter the command:
/opt/citrix/vda/bin/ctxregupdate-k "Hklm/system/currentcontrolset/control/citrix/thinwire"-V "MaxFbHeight"-D 2160

In addition, the session displays memory Citrix default 64MB (65536KB), and after the change memory requirements 3920x2160x4/1024=33075kb, you can adjust the default values in the Citrix policy to optimize memory.
Calculation formula: M=x*y*z
M is the total memory of the session display.
X is the width of the virtual session desktop
Y is the height of the virtual session desktop
Z is the color depth of the HDX session window (Linux VDA is always 32-bit color, unit bit, so 32/8=4)
