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.

The required vRAM size is calculated based on your specifications. Select the snapshot of the golden image to use for the pool. The snapshot lists the following details:
  • Number of monitors
  • VRAM size
  • Resolution

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.

For more information about changing the resolution for your instant-clone desktop pool, see the VMware Knowledge Base (KB) article
