Latitude E6400: DisplayPort not Working on Windows 7

While try connecting Dell E6400 laptop to TV via HDMI the user has facing up the trouble that actually comes. Samsung LCD TV seems said that there is no HDMI device connected. It was annoying as he just bought DisplayPort to HDMI Adapter to make it connect.


With the assumption the new DisplayPort to HDMI Adapter works properly at the E6400 and you’re installed the newest nVidia version already, you can try to use the Nvidia Control Panel and make Samsung LCD TV as the secondary display enable. So now you should have several options within that panel you can play to get it works. You can try this following to access:

- Go into Nvidia Control Panel
- Select Display
- Choose Setup multiple Display section
- Looking for a link right under the white box called “My display is not shown…”
- Click on it

The one important thing in this setting is you must switch on the Samsung LCD TV, and the right input mode is selected, else the input may be detected. After leave the Nvidia Control Panel, check if E6400 laptop to TV via HDMI is connecting well.
