Custom modes can now be configured via the registry under HKEY_LOCAL_MACHINE\SOFTWARE\LookingGlass\IDD Create the value "Modes" as a REG_MULTI_SZ with the value as a list of modes, for example: 1024x768@60 1920x1080@60 1920x1080@120* The '*' denotes the preferred mode to default to if one has not been selected by the user.
