ManagementObjectCollection objs = _auditor.Connector.CreateCollection("Win32_VideoController");
                foreach (ManagementObject obj in objs)
                {
                    Video vid = new Video();
                    _videoes.Add(vid);
                     vid.Frequency = (UInt32)obj["CurrentRefreshRate"];
                 }
