Hi. I am trying to connect my LCD TV model 26PF4310/10 to a Freeview HD box but error message 'Video mode Not Supported' is coming up. Sound works OK through separate cable. I am using an HDMI cable with a DVI-I converter. There is an article on this site explaining how to do the connection (for Sky HD) for this model and I have followed this... Any ideas why this isn't working?
