In Reply to: Mistubishi 57732 & Samsung HL-S5679...DLP Bulb vs. DLP LED posted by dingo dave on February 15, 2007 at 09:57:37:
DLP has a viewing angle of 170 degrees, the same as Plasma. LCD is 160-170 degrees, LCoS/D-ILA and CRT are 180 degrees. I have no idea what you mean by "the dark corners at 30 degrees". I have not seen this or read anything about it. Also, the newer Samsungs have been some of the best calibrated sets out-of-the-box and are very accurate after calibration.LED backlighting will eliminate any rainbow effect that the DLP may have had, it will eliminate the need for lamps, it will eliminate the color wheel, it will increase the number of colors, it will increase blacklevels and the contrast ratio. Rear projection LCD and LCoS/D-ILA/SXRD will also be using LED lighting.
I have not heard anything about LASER DLP. That would seem to be far too expensive and not very feasible. I'm betting he's confused and it's LED lighting that he's talking about. You should look into the new SED (Surface-conduction Electron-emitter Display) technology, it should be the best of just about everything and the picture should look very similar to a CRT TV. Toshiba is supposeitly(?) going to have one available this year. Also, OLED (Organic Light-emitting Diode displays), PLED (Polymer Light-emitting Diodes) and LEP (Light-emitting Polymers) are said to be coming and will replace LCDs.
You may want to think about getting a 720P Plasma and waiting another year or two for all of these different technologies to settle out?

Damn, loloks like a winner display wise but many behind the scenes issues holding it up...http://gear.ign.com/articles/752/752878p1.html
It's the litigation that's the problem but it'll get solved. Don't know if you want to want another year and a half though. SED displays are said to be fairly easy and cheap, relative to other technologies, to manufacture.
i thought about that...getting a plasma, but the tv i have now is 15 yrs old and i don't see myself dropping $2K+ in a 2-3 year time span on 2 TVs. My idea was to drop $2.5K on a set that would last 5-10 yrs.
My viewing distance is about 10 ft. so i don't know if a 42-46" plasma(which is what i would be willing to afford for a 72 plasma would be big enough.
I've seen recommendations saying that with a high def screen, the viewing distance should be about 1.25 times the screen diagonal size, other recommendations saying 2.5 times, and probably a few more that fall in between those. I watch my 80 cm (32") screen at a distance of about 2 metres which is the 2.5 times recommendation and find that fine. Being a little further away doesn't bother me. Getting up to the 1.25 times end of things does.For a viewing distance of 10', a 48" screen would give you the 2.5 times viewing distance. A 42"-46" screen would be the equivalent of me watching my screen from a bit further away than I do, and I don't think that would be a problem.
Recommendations for viewing distances tend to be closer for high def screens than they do for standard def screens because of the higher resolution. One can watch from closer distances without seeing the line structure and related artifacts, and of course you can see more detail at closer distances and that's what high def gives you: more detail. Sit too far away and you lose the benefit of that.
For your 10' distance I probably wouldn't want to go smaller than a 42" screen for my own tastes, and larger would probably be better up to, say, the 50"-52" mark but that's my taste. It's worthwhile checking out how things look to you from a 10' distance in a shop where there are a few screens in the 40"-50+" screen size on display to get a feel for your own preferences. Try viewing the same screens from a slightly closer distance as well to get a feel for what happens then. You may well find, like me, that after living with a high def screen for a while that you move things around and start viewing from a little closer. I started out at around 2.3 to 2.5 metres away from my screen and moved a little closer to my current 2 metre viewing distance after a couple of months. I probably would like to sit a little closer again, but there's something about simple physical proximity, not image size, that puts me off. I'd probably be a little happier with a larger screen and my current viewing distance so I guess I'd suggest that you consider that kind of thing as well and go for as big a screen as you can afford, providing of course that the picture quality is acceptable. I'm prepared to trade off a little size for a better picture.

If you want it to last another 10 years I think I'd probably go with 1080p although 720p is not bad either.
