1080p vs 1080i?

[Gerard]

Just wondering is there a major difference with 1080p over 1080i? Been reading some reviews and quite a few have basically stated you can't really tell the difference, however some have differered stating that there is a noticable difference.


Just wondering do you need to have hdmi to support 1080p or does it work through component, also what are examples of tv's that support 1080p?

the difference between 1080i and 1080p is that one is interlaced, one is progressive scan

Progressive scan draws every line, interlaced draws alternate lines, leaving a gap in the middle

It then relies on your eyes to fill in the gaps yourself. It does work quite well, but its generally agreed that interlaced is quite good for stuff BBC's natural world documentary, but terrible for fast paced action like football.

The big question on everybody's lips at the moment is how important is 1080P going to be. Remember that 720P is also progressive scan, and is fully supported by anything sporting a "HD ready" logo - something that nearly every LCD/PLasma has been for at least a year now (with one or two silly exceptions)

There are however, only a few LCDs that support it. Samsung / Sony have a joint venture that does (Sony has the W and X series) and the only other true 1080P LCD i know of is the Sharp GX1 (i think thats the correct model). In Plasma's, theres only one, and its a 50" pioneer and it costs £6000.

So its not anywhere like as standard as 720P. You should be asking yourself the question, can you tell the difference between 720P and 1080P ? as 1080i and 1080p you will see a difference, as one is interlaced one is prog scan. As for where you will see a difference with 1080P over 720P, its generally agreed its only on larger screens above 40"

There's quite a few actually. Goodmans have quite a cheap 42" 1080p LCD, samsung has one the F7 series, Philips 37PF9830 and Toshibas 42HL196 to name a few

What way do they support it though, most ive seen say 1080p via hdmi. Im looking for one that support it via (preferably) vga or (second choice) composite.

Could you list the names and model numbers if they do it via vga or composite please

Well i was replying to this "also what are examples of tv's that support 1080p"

You'll never find a TV that supports 1080p nor 720p for that matter via composite, I assume you meant component?

Most of the samsungs support 1:1 pixel mapping via vga so the f7 likely supports the full res via vga.

Yeah i meant component,

So that means i assume i could connect my pc to this and have it run at 1920x1080? Or am i barking up the wrong tree.

On the Samsung F7 series, yes you can, but the SD quality isn't that hot.

I'm looking at getting the Sharp LC42XD1E but it only supports 1080p over HDMI.

 

[Gerard]

Yeah i just grabbed the pdf manual and it states it does.

Be used mainly for my 360 and hd-dvd drive (1080p wooo ) but id like to hook the pc up to it to see how it looks, now to start saving the pennies

I know its a simple thing, but be aware that "supporting" 1080p doesn't necessarily mean its a native 1080p panel. Some of them rescale the input to the panels native resolution. You still get a picture, but its usually better to run the panel at native res. Generally the spec should say something like maximum resolution of 1920x1080 1:1 mapped, accepting 1080p input.

The Samsung F71 series support 1080p over VGA, Component and HDMI. My friend has the 40" version of this TV and i've personally seen it in action. I hear the 42" Goodmans supports 1080p over all HD inputs too. The 1080 panel Sony Bravias only accept 1080p via HDMI, and possibly VGA with a little messing about. I'm not sure on the Toshiba and Sharp TVs.

To get 1080p from HD-DVD on the xbox, you need to use the VGA cable. If you use component, the xbox will switch the output to 1080i on playback. Not that 1080i looks bad, but it adds an extra de-interlacing stage which isn't necessary.

It is obvious on some of the smaller TV sets (32" and below) you may not see any noticable differences in the quality of the picture when watching HD movies.


However, is this also true for gaming on a xbox 360 or PS3? Will an increase in resolution from 720p to 1080p mean the graphics look a great deal better?

360 No, as everything is internally rendered at 720p so at 1080-p it's just upsampled and I doubt offers much more than native. PS3 in 1080- yeah certainly it should look better.
