You can change the number of monitor displays for a virtual machine, allocate memory for the displays, and enable 3D support.

The default setting for total video RAM is adequate for minimal desktop resolution. For more complex situations, you can change the default memory.

Some 3D applications require a minimum video memory of 64MB.

Verify that the virtual machine is powered off.

To enable 3D support, the virtual machine compatibility must be ESXi 5.0 and later.

To use a hardware 3D renderer, ensure that graphics hardware is available. Otherwise, the virtual machine will not power on.
