This page lists any advanced configuration that is possible with the virtual display driver currently.

Custom resolutions

Starting in driver version 0.37, you can add up to 5 custom resolutions to the display via the Windows Registry Editor. Each resolution definition must be added to the path below.

• Open Registry Editor
• Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Parsec\vdd
• Create a new folder for each custom resolution you want. The name of the folder should be a number starting at 0 and increasing up to 4. To create a folder, right-click the vdd folder and select New > Key (in the registry editor, folders are called keys)
• Create values for the width, height and hz (frequency) of your custom resolution. To create the resolution values, right-click the newly created folder and select New > DWORD (32-bit) Value

• Double click each value to edit them. Because registry DWORD values are hexadecimal, when adding each value it is helpful to select the radio button to 'Decimal' so you can type the value normally

• To apply the resolution change, disconnect and reconnect to the host with virtual displays enabled

The resolutions will be available to be selected from the Windows display settings, but can also apply if "Use client resolution" is used on the host settings and a client with the same resolution joins

Select Parent GPU

Starting in driver version 0.45, you can now select which GPU the Parsec Virtual Display Driver attaches to. This is most helpful when your Virtual Machine vendor includes a software video adapter as it's POST adapter. Setting the Parsec Virtual Display adapter to use a physical GPU like the NVIDA or AMD card will improve reliability of the Parsec Virtual Display Adapter.

• Open Registry Editor
• Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WUDF\Services\ParsecVDA\Parameters
• Double-click the existing DisablePreferredRenderAdapterChange and modify its value to 0
• Right-click anywhere that is empty on the right and select New > DWORD (32-bit) Value
• Name the value PreferredRenderAdapterVendorId
• Double-click the newly created value and insert one of the hexadecimal vendor IDs listed below that matches your system hardware

• Reboot the host machine or disable and enable the Virtual Display Adapter inside device manager, to apply the changes
