Fix Recommendation

From the vSphere Client select the Virtual Machine, right click and go to Edit Settings >> VM Options Tab >> Advanced >> Configuration Parameters >> Edit Configuration. Find the "mks.enable3d" value and set it to "false".

Note: The VM must be powered off to modify the advanced settings through the vSphere Web Client. It is recommended to configure these settings with PowerCLI as this can be done while the VM is powered on. In this case, the modified settings will not take effect until a cold boot of the VM.

or

From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the following command:

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
