can somebody clear this up.
i was under the impression HDTV was broadcast at 1800res, but there's HDTV "ready" LCD's where the max resolution is only 1280. am i missing something.

The resolutions are 720 and something like 1024 (bit more i think). 1024 being the max and the one that tv broadcasts will be in. 720 is the one that will be used for xbox 360 (for most games anyway)Quote:

still dont get it, whats all this 1800 business then? :|
I figment of your imagination
Your probably waffling on about the 1080i, which is the same as 720, but better quality again
HDTV has two resolutions.
720p and 720i (interlaced and progressive)
and 1080i.
1280x720 and 1920x1080 respectively.
Edit: 720 and 1080 lines as opposed to 576. Or 625. One of the two. Lol
Ok,
First modes are actually 1080i (HDTV) • 720p (HDTV) to correct myself :)
Take a look at this spec for a random Panasonic HDTV
http://digitalmedianet.dealtime.com/...onic_TC_32LX50
When buying just make sure your tv's got capability to display 1080i and has at least one HMDI port (for mega qulaity connection to new dvd players)
:)
Isnt buying a TV that does 720i now a waste then?
When you can wait and get a mega 1080i @ 1920 lines or something stupid in a couple of years time
:eek:Quote:

so...
19" tfts are gonna run at 720i? which aint as good as 1080i?
im so confused lol.
does anyone know of a TFT thats runs at 1080 and can be used as a monitor and pc?
Most HDTV LCDs can be used as monitors, although the quality isn't that outstanding
720i is pretty rare - 720p is much more likely.Quote:

if you are looking to buy a hdtv panel, ensure it has hdmi in, and a 1280x720 resolution. some panels have larger resolutions (1280x768, wxga (iirc) seems popular) but this will either lead to source stretching (to make it fit the pixels) or the source will be squished top-bottem slightly (the geometry, to make the pixels match 1:1), and have borders.
all hdtv sets will plummet in price over the next year - i forsee a bit of a price war once the xbox360, ps3, sky and ntl are all pumping out occasional hdtv. i want one for above me bed, but i'm going to wait until the prices have settled a little.
i'll wait till just before the world cup then :)
sounds like a good plan - the situation may well have changed by then.. who knows?
as for the monitor point - a good quality hdtv set (ie, one thats costing around £500 for a 20") will make a good monitor if viewed from the right distance -in fact it may well look better for lots of games/movies as there will be less artificial artifacts..
1080i and 1080p will be pretty much limited to pre-recorded media (blu-ray, hd-dvd), or pc connectivity.
You might get the odd satellite channel with 1080i (Euro1080 is one such channel), but they'll be few and far between until there are high-bandwidth VOD lines available (like Japan for example as a single uncompressed 1080 video stream will require a minimum of a 50mbit line).
and yes steve, they can be hooked up to a pc and used as another monitor - the quality isn't an issue if you tweak the settings (if you're connecting via a vga connector), or hook it up via a dvi/hdmi connector.
1280*720 panels pretty much don't exist, LG have 1280*768 panels, but by far, the vast majority are 1366*768, which allows for 1:1 scaling by a factor of 1.066666etc which is un-noticable.Quote:

In order to show the 'HD Ready' logo the TV must be able to receve a 1080i signal. It does not have to have that native resolution (most can only do 720p), but if it receves a higher res signal the TV must be able to down sample it, rather than just give up.
As many people know, Sky are planing to lauch a HD service next year. They are currently broadcasting test transmitions, most of which are in 1080i.Quote:

Also, all this stuff is broadcast digitaly using advanced codecs such as MPEG4 or H264, so the bandwith requirements are more complex than just counting the number of pixels per seccond.

Gaming is going widescreen and if its a viable option it may be worth considering.
TV and second monitor, but not as your primary (the resolution isn't there with the 720p sets) but for pumping out HD video and the occasional game it's great :)
btw, the best software I've found yet for scaling video up is WinDVD 7, but you're stuck with WMP if you want to play HDTV transport streams (windvd judders, and vlc isn't as good either).
actually, whilst test transmissions might be in 1080i, hd.sky.com suggests it's pretty pointless & they'll be using 720p almost exclusivelyQuote:

Fast-moving images would work better at 720p because the whole frame is refreshed each time, so its preferable for sports, and probably also general-purpose TV.
Additionally, the recording equipment for 720p is significantly more affordable than 1080i - there are even consumer-level cameras reaching the market that can handle 720p. 1080i is fine for film-to-digital transfer and rendered imagery, but otherwise would require even more expensive digital film equipment. You'd expect to see roving news teams using 720p rather than 1080i because of the availability of prosumer-level 720p camcorders.
From what I've read, insiders are expecting movies and sports to be some of the main driving factors for HDTV, so 1080i isn't the preferable solution for the majority of the primary content they're looking at, so combined with the higher production and consumer equipment costs, 720p looks to be the dominant format for the next few years at least.
Actually I was reading a magazine about a week ago that reckoned that 1080p sets were all over the latest trade show in the states. TI's latest DLP chip (called the HD3 or something) is 1080p capable, so now pretty much any projector/ RPTV manufacturer can produce 1080p equiptment (for a price, of course).Quote:

If you click on 'televisions' you can search for 1080p resolution televisions- so far lots of models from Mitsubishi, Samsung and Toshiba are listed.
Edit: the 1080p chip is the HD3+.
This reminds me of the VHS / Betamax clash. The Betamax format was the better one, but the VHS format triumphed because it was the more accessible.Quote:

So, let's just hope that things remain flexible enough so that better resolutions (1080p in this case) can still be successful when the market is more favourable.
