HDMI not working

Hi msc1984,

Thanks for posting.

Check to make sure you have the correct cable, and that your settings are configured to display to the television.

Here is an explanation of the cables:

Standard HDMI Cable
The Standard HDMI cable is designed to handle most home applications, and is tested to reliably transmit 1080i or 720p video – the HD resolutions that are commonly associated with cable and satellite television, digital broadcast HD, and upscaling DVD players.

  Standard HDMI Cable with Ethernet
This cable type offers the same baseline performance as the Standard HDMI Cable shown above (720p or 1080i video resolution), plus an additional, dedicated data channel, known as the HDMI Ethernet Channel, for device networking. HDMI Ethernet Channel functionality is only available if both linked devices are HDMI Ethernet Channel-enabled.

  Standard Automotive HDMI Cable
Supports up to 720p/1080i (does not support HDMI Ethernet Channel). Since an automotive system may be wired with one or more internal relays that can affect signal strength, the Standard Automotive HDMI Cable needs to send a stronger signal than other cables types, so it is tested to higher performance standards.

  High Speed HDMI Cable
The High Speed HDMI cable is designed and tested to handle video resolutions of 1080p and beyond, including advanced display technologies such as 4K, 3D, and Deep Color. If you are using any of these technologies, or if you are connecting your 1080p display to a 1080p content source, such as a Blu-ray Disc player, this is the recommended cable.

  High Speed HDMI Cable with Ethernet
This cable type offers the same baseline performance as the High Speed HDMI Cable shown above (1080p video resolution and beyond), plus an additional, dedicated data channel, known as the HDMI Ethernet Channel, for device networking. HDMI Ethernet Channel functionality is only available if both linked devices are HDMI Ethernet Channel-enabled.

If you need additional assistance, please post back and the experts here can answer.  Thanks.

Thank you for the info. I tried the cable with a different laptop to TV and it worked fine.  It seems like my port is not working, is there a command key to turn it on and off?
