Hi,
Thought we should have a thread about true high definition TV's.
Seeing and the consumer market is begining to flood with LCD TV's that 'HD ready', I thought we should talk about the different supported resolutions LCD TV's have at the moment and why most of them aren't truely capable of displaying the true potential of HDTV.
so lets' get a few things clear first HDTV can be 720p or 1080i or 1280x720 pixels progressive and 1920x1080 pixels interlaced.
While for the inital launch of HDTV we're probably gonna see 720p for the most part as is a massive leap forward in quality from current broadcasts, 1080i is truely where I think we all really want to go.
the vast majority of LCD and Plasma TV that are HD ready on the market currently only support a maximum resolution of 1366x768 pixels or around that. which is good to display the 720p HD feeds but what about the 1080i feeds, anyone who buys a TV that only supports this resolution isn't going to benefit from true 1080i HDTV.
so what 'true' 1080i TV's are out there at the moment, one's that have a resolution of 1920x1080, well all I can find at the moment are (UK market):
Philips - 37PF9830 37" LCD - £2,500 aprox.
Philips - 42PF9830 42" LCD - £3,300 aprox.
Sharp - LC-45GD1E Aquos 45" - £4,200 aprox.
does anyone know of anymore

1080i looks noticeably better on a 1366x768 display than 720P does. 1080i is downsized and 720p is upsized.
The only true 1080i display out there would be one that is interlaced and displays 1920x1080 resolution. I don't think any exist, at least not typically available. What you would be looking for are 1080P displays which would de-interlace the 1080i image.
I'd still get one if I had the chance
There's one for only $1500 in America that is 37". There is also a new 20" that is 1440x900. As screens get cheaper they will all go to 1080P.
They'll hook up their Sky/cable/PS3 or whatever and just get on with enjoying HD images.

got to gets me one of these babies
Any other links to other brands that have 1920x1080 true HD TV for the UK market please post
Go and do some research on HD and you'll see that 720p is by far the most used format. Getting a TV just because it has 1920x1080 resolution is pointless. Barely any programmes are even broadcast in that resolution in the States, and I doubt we'll even see it here. Add to that the fact that many 1080i-based programmes are not actually 1080, but are much lower resolution but upscaled and you'll see you're wasting your money.
By buying a screen with such a high resolution all you're doing is adding to the scaling that must be done. 720p broadcasts will have to be scaled to fit your screen, which is not going to look as pretty as you'd think, so in the long run you'll be losing out.
But, I guess it's the classic 'mine's bigger than yours'... :rolleyes:
I thought all HD on CBS and NBC was 1080i.
You are incorrect. The most widely used HD format, by far, is 1080i, which can only be best viewed on a 1080 resolution screen. This is based on the biggest HD market that exists in America. In Japan, they support 1080i only.
1080i programmes in America, since that is where the vast majority of HD is produced, are in fact 1080 and not upscaled.
Your last point about upscaling 720 is the only correct part of your statement.
That is correct. This is how it stacks up.
28 channels broadcasting 1080i
CBS
NBC
UPN
WB
PBS
Discovery
Showtime
HBO
HDNet
HDNet Movies
Cinemax
Universal
TMC
Starz
TNT
INHD
INHD2
Ultra
Monsters
RAVE
Equator
Gallery
Animania
RUSH
HD News
Guy TV
Majestic
NFL Sunday
3 channels broadcasting in 720p
ABC
ESPN
Fox
I may have missed a few overall but that essentially shows the difference.
Hardly! It makes a lot of sense to buy the best resolution available so you can watch 1080 properly. 720p upscaled is going to look a hell of a lot better than 1080i downscaled and one day everything will be in 1080i/p so why buy another TV when you can get it right first time?
I know this is an LCD thread but most DLP sets are 1080i it's just plasma/LCD which lag behind a little
Actually that is incorrect. Downsizing an image will always yield a much higher quality image than upsizing for the simple reason is that you can not create what is not there in the first place. You can get a good feel for that by taking a still image on your PC and resize and upsize in a typical image editing program. The downsized sample will look excellent, even if it may need a bit sharpening, but the upsized one will look soft with what looks like fat or thickened details.
1080i downsized to 720P resolution screens will look excellent with little to no noticeable quality degradation besides the smaller resolution size. 720P upsized to a 1080p screen I am afraid to say does not look very good as you are attempting to double the information in the image. It's another reason why i think 720P will not last for too long.
Most current DLP TVs are 720P but newer models in America are 1080P.
I agree on your first point of buying a 1080P screen to properly enjoy 1080i and p material.
sanderton, I'm pretty sure most, if not all HD DLP's are 1080i (not p). Sagem do one that springs to mind immediatly
Only worse to the extent of it being a smaller resolution picture but perfect for a display that matches such a resolution.
Upscaled 720 to a 1080P looks worse than watching it natively on a 720P screen. It's just too much to blow up.
Most DLPs are 720P but newer 1080P models are on sale in America mainly.
ABC and FOX also have plenty of sports coverage on their network channels. EsPN is supposedly looking into 1080P broadcasting. They are also owned by ABC.
I think most/all of the ones here are already 1080i
The 720 sets can accept a 1080 input and downsacle it; perhaps thats's what;'s confused you?
So for the price, 720p TV is good enough, no?!

They seem to be selling these quite quickly
There's a thread on avforums about it :

There are 1080p TVs for sale in the UK. The Sharp 45G1DE is one of them. Quite a few UKers over at avforums.com have one.
