It doesn't support the full res over VGA, that i know.

Don't know about component though.

I can't say I've ever tried one?, but the PC Setup menu has a number of options, one of which (Normal) displays the picture at it's original size - presumably if that's the same size as the panels resolution, then it will display at full res?.

i think he means the set will only display 1080p over HDMI interface, not component and VGA. with the last 2 scaling would be involved

yeah thats what i meant sorry, will scale up then

Sorry? - you're feeding a 1080 signal into a 1080 panel, it doesn't need to scale anything? - P or i makes no difference to scaling. Certainly ALL the sets that I've tried via component work fine at 1080, and certainly the W2000 does.

What the poster means is that the TV specifically cannot handle 1080p over component, so to get a picture from a Blu-ray player etc over component you must select a lower resolution on the output device, such as 1080i (which must then be deinterlaced/line doubled/upscaled - take your pick). I've noticed that you often use the generic term '1080' when referring to resolution but 1080i and 1080p are absolutely not the same.

The resolution is the same! - it's 1080 horizontal lines.

The difference is in the number of frames per second, with 'P' you get 50 frames per second, with the interlaced 'i' you get 50 half frames per second (25 full frames per second). Because of this 'P' may give a slightly better picture on fast moving scenes, but this may not even be noticeable - in any case, it's not a resolution change, and no scaling is required.

nope!
VGA=
Maximum of 720 h lines
Maximum of 480 v lines

component video wont support 1080p eg the xbox 360 (less the Elite that has hdmi output), so your right on that one, but 1080i is not the native resolution of the w series, and as you know, a matching input gives the best picture.

sorry to pick you apart nigel, but with reg to p and i, its more specific than frame refresh rate.
Progressive is every line refreshed every second
Interlaced is every other line every other second (hence interlaced) and obviously the refreshing of lines on a screen = frames

Can someone please tell me whether I'm likely to regret it if I buy a 1080i TV rather than a 1080p one? I had more or less decided on a 42" Panasonic plasma, but although it gets great writeups, it's only 1080i. And I really have no idea whether this will actually matter.

I have Sky+ (will probably get HD at some point in the future but not immediately) and a Wii (again may well get a 360 or PS3 at some stage). Not intending to buy a Blu-Ray or HD-DVD player until it becomes clearer which version is likely to become standard.

You won't regret it. It's one of the best TVs on the market!

@Nigel. I'm sorry but you obviously don't understand interlacing.

Film material may consists of 25 frames per second, interlaced video is 50Hz. Whenever there is motion between fields the resolution drops to the field resolution, e.g. 540 lines in a 1080i broadcast.

Take a look at this guide.

Sorry I would disagree - the resolution is still 1080 lines, but you may have movement between the odd and even lines (as I said before).

Also bear in mind that LCD and Plasma displays are not interlaced, the 'i' picture is displayed as a single frame, not as two half frames as with a CRT.

I suggest you check again! - the W series are full HD sets - their native resolution is 1080.

Have to admit, I'm very confused about the resolution of interlaced and progressive!

Is it the case then that 576i (normal SD broadcasts) only has a vertical resolution of 288?

With 1080i, I can see that only 540 lines are transmitted in every field, but are these the "same" 540 lines? i.e. is field 2 the same 540 lines as field 1 but shifted down by one line and slightly further on in time (the whole picture is only divided into 540 lines)? Or is it a full 1080 resolution (i.e. all lines are different and the picture is divided into 1080 lines) but only half the lines are transmitted in any one field?

Without knowing the exact technical details, I would have sided with Nigel (that'll be a first ) in that 1080p and 1080i are both 1080 lines but progressive transmits all lines in one go 25 times a second and interlaced transmits half the lines 50 times a second. The reason why some people find that 720p can look better than 1080i is, as the article linked above explains, you get "split" motion on LCD and Plasma (interlaced video on a progressive display).

To explain what I mean by "the same" 540 lines...in the diagrams of the split circle in the above guide, the successive fields do show different lines, i.e. the top and bottom half of the circle. It's not as though it's just the top half of the circle that's repeated in the next field but down one line and slightly further on in time. The top and bottom halves of the circle equate to Line 1 and Line 2, in other words regardless of whether the display is interlaced or progressive, the circle is split into exactly the same number of lines. Let's say these diagrams equate to 2i and 2p. The resolution is still 2, surely??? When reassembled into the full picture. You only get a resolution of 1 in any given field but the eye is too slow to resolve that and when viewed on a CRT or a a progressive display that de-interlaces, you see the full 2 lines that the original picture was split into.

i suggest you check my post again, i said the native res of the w is NOT 1080i, implying it is 1080p, as would make sense if you consider what i was replying to

Obviously not, just as 1080i isn't just 540 lines.

No, you get the odd lines one field, and the even lines the next, forming a single 1080 resolution picture.


Most people are using a Sky HD box (or something similar), so all HD pictures are 1080i - setting the box to 720P doesn't magically convert the picture to P, it's just a 1080i picture displayed over a P interface. If it's better like that, then it's down to the TV set, not because it's a P output.

As always, try both settings, see which you prefer, it's a customer setting, that's what it's there for.

If you're using a real P source, like a PS3, and the TV will accept 720P but not 1080P, then there may be an improvement by setting it to 720P - again, try it and see what you prefer.

I fail to see the point?, the panel has a resolution of 1080, it's not 'i' or 'P', it's just 1080 pixels high. Doesn't matter if you feed it 1080i or 1080P there's no scaling involved, as both are the same correct size.

this is silly. your clearly not paying attention to posts properly.
re-read posts 24 to 33, that will help you see the point

No?, none of them seem to make any sensible point?.

Which statement below do you disagree with?.

1) The W series has a 1080 pixel (full HD) panel.

2) It will display a 1080i signal without scaling.

2) It will display a 1080P signal without scaling.

BTW, in post 33, where you mention VGA - I'm presuming we're talking about modern PC resolutions, and not antique standard VGA resolutions - where the TV can be set to display it as a scaled image, or actual size, as you wish.

cool yer jets their man!! im not biting at you!







totally agree. at no point have i suggested the w is otherwise.


depends what the input is??



depends what the input is


yes, Video Graphics Array, as i also assume the original poster Pawlo meant.

why do you ask these questions?? all i was doing was answering the above post, and everyones input seems to make sense to me.

hmmm anyway...I have actually got a sony KDL-40W2000, bought it yesterday for £850-00 from sound&vision : http://www.soundandvisiononline.com/...oduct_id=11811

It is full 1080p but only over HDMI not component or VGA.

verry few tellies support 1080p over anything but HDMI due to HDCP complications

Hi folks, I work in my local Sony Centre, been within the industry for a good number of years, let me try and clarify a few things I've seen in this post

The KDL40W2000 is a 1920x1080 native resolution screen. It can obviously handle up to 1080p modes.

Being 1080p mode (HD1080, or FullHD, depending on what sticker is being shown!), means the set can display all 1080 lines at the same time, without need for refresh or interlacing. So, for example, your PC monitor which can display 1280x1084 is similar, except with a slightly lower resolution.

Now, when showing a FULL HD signal, from say, a blu-ray player, which can be set to always show a 1080p signal, regardless what the source is (known as upscaling), the panel will show all 1080 lines at once, with no need to interlace the signal.

1080i, which is interlace mode, and the highest mode that Sky HD can broadcast at, shows 525 ODD lines, then 525 EVEN lines of the same frame.

So, to answer the questions posed:

Will the TV show a 1080p mode natively. Yes it will.

Will the TV show a 1080i mode natively. It will show the odd/even frames on alternate lines. So yes, in a way it is native. Obviously the overall framerate will reduce to 25Hz, but then if it's say, a movie, that won't matter. It is noticeable more on a live broadcast, where the framerate will have a much higher impact.

In most stores, the aerial is boosted over a large network of cables, resulting in very poor SD (and even HD via Sky) picture quality. At home, it is VASTLY improved.

And don't forget upscaling machines will interpolate the missing lines to show a higher resolution picture. This is not the same as interlacing.

I think you're mistaken?.

An LCD (or Plasma) writes the ODD lines into a buffer, then writes the EVEN lines to the buffer (obviously both in the correct places), then it displays the entire 1080 lines (or however many the panel has - but in this case 1080) at the same time. In the case of a Plasma it displays the same picture from the frame store 256 times, in order to get variations in brightness - Plasma pixels can be either ON or OFF, no where in between.

This is why people call LCD and Plasma 'Progressive' displays, which isn't really something I would agree with - Interlaced and Progressive apply to the transmission, not to the panel.

Hmmm...

1080p - the picture is sent to the set as 1 frame of 1080 lines, and sits in the frame buffer.

The frame is then rendered to the screen (the next frame is being written to the frame buffer).

This will be at 25 frames (half standard PAL frequency at 50 fields per second), or whatever.

Ordinarily a 24FPS film will be shown at 25FPS (on PAL systems), which is why the run time for a film will be slightly quicker. Americans tend to do things like "pulldown" in order to make the 24FPS of a film fit in with the 30 frames of NTSC. Check IMDB runtime vs PAL DVD runtime if you don't believe me!

1080i - the picture is sent to set as two "fields" - odd lines and even lines. The odd lines are written to the buffer, then the even lines are written to the buffer.

There are 50 fields, or 25 frames per second.

***********************************

The full buffer is rendered to the screen - it is always rendered progressively, irrespective of the source material, the interface it came in on, or whether it's a Wednesday or whatever.

An interlaced picture is made by sampling the original source - it samples the source material twice, once for odd then once for even. If the material is fast moving action (i.e. sport) then the source will differ slightly in each sample.

This means one 1080i frame will tend to show interlacing artefacts (tearing) whereas a 1080p frame will not, since a complete picture is sampled in one go (like a photo).

The screen can/will be refreshed independently of how often the buffer is filled.

You PC monitor is probably being refreshed 75 times a second. It can still display a 24/25/50i/60i picture with no/little tearing/jaggies.

How a screen does this will depend on it's price tag and the complexity of it's rendering/upscaling/deinterlacing engine.

SkyHD (or any other DTH broadcaster) will not offer 1080p @ 25FPS since this is considered a "perfect" digital copy.

You work in a sony center.....How much can you get me a PS3 for
