You can specify the number of monitors and resolution for your instant-clone desktop pool in the 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 vSphere Single Host Management in the vSphere documentation.

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