Fix Recommendation

For each virtual machine do the following:

From the vSphere Client, right-click the virtual machine and go to "Edit Settings".

Expand the "Video card" and uncheck the "Enable 3D Support" checkbox.

Click "OK".

or

From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the provided commands as noted below.

If the setting does not exist, run:

Get-VM "VM Name" | New-AdvancedSetting -Name mks.enable3d -Value false

If the setting exists, run:

Get-VM "VM Name" | Get-AdvancedSetting -Name mks.enable3d | Set-AdvancedSetting -Value false

Note: The VM must be powered off to configure the advanced settings through the vSphere Client. Therefore, it is recommended to configure these settings with PowerCLI as this can be done while the VM is powered on. Settings do not take effect via either method until the virtual machine is cold started, not rebooted.
