I am trying to connect my LCD Hi-def television to my computer so I can watch internet on my tv. The tv is showing "invalid signal". What is this and how do I fix it? I have the dynex DVI-D to HDMI Cable and Mac converter.

Hi,

You can only use your TV for viewing internet from your computer by using the TV as a PC monitor. To do this you should connect your computer to your TV using a standard VGA cable - the same as you would use to connect your computer to any other external monitor. You should note that this cable doesn't carry a sound signal so you can't use the TV speakers for sound output.

However, you can connect an HDMI cable from your computer to your TV to play media files or DVDs. This cable does carry a sound signal so you will be able to use your TV speakers here. This cable cannot be used for turning your TV into a PC monitor.

And all of above shouldn't be confused with "Internet TV". This is something totally different and requires your TV to be connected directly to the internet.

Hope this helps.
