Apologies in advance if there is an existing thread on this, please point me to it!

I have just bought a plasma TV that is HD ready, so how do I make it full HD? Do I need to? What is the difference? Why is everything so complicated?

Thanks.

What the exact tv you have?
Some tvs are FULL HD 1080P
Others are (usually) just over 720 pixels (756 ish)
720 is also high definition, just not as high as 1080
If your tv is a 756 (ish) model, then you would probably benefit from a 720P picture more than you would a 1080P due to the scaling involved
P = PROGRESSIVE (Full picture)
i = INTERLACED (picture in 2 parts then joined together)
Progressive generally looks better than interlaced (dependant on the tv though)

I see the BBC still asks for programmes to be delivered in 1080i so I wonder if they are changing?

You CANT make an HD set Full HD, you have to buy a new "Full HD Ready" set!

HD is 4x sharper than standard definition.

Not quite. For a start sharpness isn't really the factor here, it's resolution and they're not synonymous terms. Secondly HD isn't just one resolution, simplistically the horizontal resolution could be 720 or 1080 compared to SD's 576. Full HD/1080p might have approximately 4 times the resolution of standard definition but it doesn't apply to all high definition standards.

I understand the full speck for a HD TV is
1080i x 1920 is this right. not 1080i x 720

From the BBC HD website

The BBC HD channel currently transmits programmes using the 1080i standard.
