Hi, I am using a Dell XPS M1330 laptop which came pre-installed with Windows Vista Ultimate 32bit. I usually connect external displays to this system as it has a VGA as well as a HDMI Port. I was able to use external Monitors or Projectors through this HDMI post in past using Windows Mobility Center without any problem but since past 10 days I am getting some problems. Recently I connected my TV using the same HDMI port and since then I guess something went wrong.
Now no matter I try to connect external monitor, Projector or TV, nothing seems to be working. Mobility Center is not able to detect and external displays connected to VGA. Whenever I try activating the option to extend the desktop to an external monitor using the graphic cards driver or the display panel in the control panel, it works fine but wont work at all with Windows Mobility Center. I also tried mirroring the external monitor but still it is not detected.
Any idea what would have gone wrong and how can I fix it? Many Thanks.
