If you buy an LCD TV with a built-in Freeview HD tuner you'll be able to view high definition content straight out of the box. But even then, the number of HD channels on Freeview is limited, so if you want to get the most out of your new LCD television, you'll need a few accessories.
If you love movies you should consider picking up a Blu-ray player to plug into your LCD TV. Blu-ray is the next generation of DVD, and provides razor sharp, high definition image quality that will show what your new TV is really capable of.
If you're looking for the largest selection of HD channels, then you'll want a Sky HD box and subscription. Sky's HD service will provide a plethora of movies, entertainment, sport and documentaries in crystal clear high definition.
If video games are your thing, then the Xbox 360 or PlayStation 3 will provide cutting edge, high definition gaming on your new TV, plus the PlayStation 3 will double as a
Blu-ray player too. The latest high definition kit will also require new cables to connect them to your TV, so you'll have to replace your old SCART leads with new HDMI cables.
