You can specify the number of monitors and resolution for your instant-clone desktop pool in vSphere Client by setting those parameters in the golden image and taking a snapshot.
- Number of monitors
- VRAM size
The instant-clone desktop pool created is based on the golden image snapshot and inherits those memory settings. You cannot configure these settings in Horizon Console for instant clones.
For more information about configuring video memory settings in vSphere Client, see the vSphere Single Host Management document on the VMware vSphere Documentation portal.
