What is HD? HD vs Standard TV How to get HD Compare HD Services
The very best way to see the difference between Standard Definition and High Definition is to see it! Simply click the image below to flip between a SD and HD image taken directly from the film Avatar.

So why the big difference in quality?

The Standard Definition picture you get on Freeview or non HD services is quite small, in some cases the size can be around 544 pixels wide and 576 pixels tall. Whilst this might not mean anything, take into consideration that a Full HD Ready TV these days are capable of displaying a picture of 1920 wide and 1080 pixels tall.

Therefore, when you connect HD equipment up to your TV like the excellent Sky+HD box and tune into one of the many HD channels available, your TV will now be receiving a picture in the same high resolution that your lovely HD Ready TV can support.
