Rear projection or what

soulandy · 11-11-2004, 23:08

I'm looking to replace my 28" TV which has just conked out after 6 years and have been looking at these rear projection ones. There are a few that are coming down in price in the shops & the net but was wondering if anyone out there has one and what are they like. Only seen them in the clubs. Also wondering if it might be worth going for a LCD instead. Also, whats the difference between 100hz & 50hz. They all seem to be 100hz at the moment. So much choice it's a bit baffling.

Cheers

I can't help much, as I'm also looking for a new TV, but I have learnt in the last few days what the difference is between 50hz and 100hz:

50hz - This is what normal TVs use and always have used. There's nothing particularly wrong with it but you can sometimes see flicker on the screen.
100hz - This is the new technology. It makes for a cleaner picture with a lot less flicker, but it can sometimes look unrealistic (especially during fast-moving shots, such as live events and football), and can cause similar colours (such as the green colours of the grass on a football pitch) to mix together, thus losing texture.

I hope this is of some help to you.

In terms of sheer picture size per pound, RP sets are first rate.

But - they must be driven by a DSidigisarssal Freeview or Sky digital box for any kind of success.

Analogue recpetion, which most have is very difficult and impossible to display propery.

Hi.

I'm no expert on rear projection TVs and thought they were poor but what i saw yesterday at my local Comet store has changed my mind quite a bit.

See my post in the thread "HDTV - how good is the picture quality" below, where I give my comments on the Sagem 50" DLP Rear Projection tv.

It was quite simply the best TV on display by far, superior picture quality to not only the CRTs but made the high spec plasmas also look ordinary.

Best pic quality I've ever seen and I've decided to buy one of these for Xmas.

PS. Can someone here kindly elaborate on the pros and cons of DLP rear projection Tvs... are they generally superior to ordinary RPs ?

Sorry about the gibberish in one line of my last post - don't know how that happened.

DLPs are very good indeed, although I must say I would be a little nervous about all these "moving parts" inside and would want to know their likely shelf life.

However this week's interesting news is that Samsung have developed a new form of CRT which is about the same size as a projector unit and potentially much cheaper - look on the DTT site under news from members.

However watching a DVD on a well set up conventional RP set is still pretty impressive - it's the broadcast sources that can be a let down at times.

I have a GDB2 freeview box at the mo so that should be OK. Well it would be if that worked OK!!!! With all the freezing that is happening with that at the moment I micht even change that.

Thanks for the replies

saw the sagem axiom tv (£1999) in comet yesterday
it is has without doubt the best picture i've ever seen
the dlp component is designed for 100,000 hrs
and the lamp is designed for 8,000 hrs
it's capable of displaying up to 1,080 interlaced lines
and 720 progressive lines
tvhd compatible for a quality that is 20 times
better than electro-magnetic tv and up to 2
times better than dvd
http://www.sagem.com/nso/uk/eng/spec...ch-xeeng.shtml
imo dlp will outsell plasma/lcd sets
dlp systems originally cost between £6,000 and £100,000
i can understand now why 100hz rp sets are now half- price

Couldn't agree more thms,!

I've had one or two private messages, asking me if I'm a Sagem salesman (lol) because of the way I exaggerate their new TV... but believe me, this is some piece of kit .. and has to be seen.

Words cannot do justice, to the picture quality of the Sagem Axiom 50" DLP screen.

Plasmas, yes even the top of the range ones by Panasonic and Sony, look like "toys" in comparison.. when it comes to picture quality, contrast, brightness and sheer intensity and vibrance of the colours.

Whether we're being conned into thinking like that because of the HDTV signal they've connected to it at Comet, I dont know.... but boy, is it impressive !!

However.. I'll just add my only concern with these DLPS is the lamp life as someone's mentioned in this thread.. I've spoken to one of the guys at Comet and he said that you'll need to replace it every 2 years or so.. which can be quite costly for a 50" screen .. apparently a replacement lamp could cost as much as £500 quid.

so that's put me off the time being, otherwise I was all but thinking to splash out the 2 grand for X mas.

it's still worth it though
after seeing a dlp television
there is no turning back
lcd and plasma prices
are plunging as i type
after reading about the
technology involved....

dlp is the new king

lcd and plasma are obsolete

the link above refers

"colour

dlp technology reproduces a range of colours up to eight
times greater than that of analogue projection systems
in television and home theatre systems, dlp projection
creates rich blacks and darker shades than is possible with
other technologies. at the movies, dlp cinema technology
projects no fewer than 35 trillion colours-over eight times
more than is possible with film

dlp colour is becoming even more brilliant as we introduce
sequential colour recapture or scr, an innovation that will
enable dlp projection systems to bring up to 40 per cent
more lumens to the screen than was previously possible"
