1080i or FULL HD 1080p?

This is a different issue than Standard Definition VS High Definition (see above). In this case it refers to the screen resolution of the TV. The resolution of the TV is measured by the number of lines and pixels. The higher the resolution, the clearer and sharper the images.

A 1080i TV has a resolution of 1920 x 1080, made up of 1080 interlaced scanned lines.

A FULL HD TV has a resolution of 1920 x 1080, made up of 1080 progressively scanned lines or 1080p.

The difference between the 2 is the refresh rate. Interlaced alternatively refreshes half the lines at a time. Progressive refreshes all the lines together. However this happens so many times every second that you can not see it. It can however be perceived as a level of image quality.

1080p is quickly becoming the norm when you buy a new Digital TV.

Equipment retailers like to promote this standard as a superior viewing experience. However whilst it is particularly important if you plan on using a High Definition DVD player (Such as Blu-Ray DVD or even Sony Playstation 3), it should be noted that currently most Free-to-air Digital transmissions are only broadcast in 576i. Only the High Definition channels are broadcast in 1080i and none are broadcast in 1080p.

At the moment you can only expect to get the full benefit of a 1080p when viewing HD content. HDMI cables are also essential.

It is case of the lowest common denominator. Performance will be capped by the standard of cables used and input quality level.

The purchase of a FULL HD TV may help to “Future-Proof” your purchase.
