How many of you bought a high definition television set this year? Did you make sure you bought one with the HD Ready logo just to be sure you were buying a set that "future proofs" you against further change?

Well I have a bit of bad news for you. Every television manufacturer here at CES is now trumpeting something they are calling "Full HD".

I bought a high definition TV this year and I was confident that my TV was capable of displaying full HD, at least no-one told me it was "less than full HD".

So what is "full HD"?

Basically it's a TV capable of displaying a resolution of 1080p - 1920 × 1080 or about two million pixels.

Many televisions in the last year had a top resolution of 1080i - a slightly less high quality resolution where the lines in the image are shown sequentially instead of all at once in the case of 1080p.

So does it mean your TV is defunct if it can't display 1080p? Absolutely not.

You would only spot the difference between 1080p and 1080i if you were viewing content in that format on a TV over 40 inches in size - and even then it's subjective to some.

But the TV makers have got a new feature to sell and of course they want to charge a premium for it.

So if you haven't got 1080p, don't lose any sleep over it.
