Two things to consider:
Having an integral freeview HD receiver has been mentioned. Originally, they did not think HD could be sent over the air and so most Freeview receivers will not pick up HD broadcasts. These are on channels 50 - 52 at present. Freeview boxes will not see these channels. So you need to make sure the TV has a newer Freeview HD receiver which will. Also, not all the UK has HD broadcast yet. (I'm lucky in the NW to have it)
Secondly, you may consider if you want to connect your TV to your LAN. Some have this facility and you can then share your PC Media on the TV (photo's, music and some video) as well as connect to some internet sites such as You Tube.
Hope this helps.
