lcd vs rear projection vs dlp vs plasma

[jorg]

ok i have done a search and nothing like this has come back. has any one had of has spent time with these types of tvs? if so what has the best picture quality and life span?and can they have more then one native resolution?(i heard dlp can be native on 1080i 720p 1080p[is this true?])?any one know what type of tv is best for brightly light room?

i know for sony products ablest there rear projection tvs has much greater contrast ratios then lcd flat screen around 6000+ and plasma have realy high contrast ratios
i know plasmas suffer from burn in but some person at bb that they have "fixed" this with the newest generation of plasma tvs. fact or B.S?
i was also told that with dlp you don`t need to replace the bulb as often as rear projection.

You say you have a brightly lit room. Is the location or the tv receiving direct glare or is it just a bright room. If its bright I'd go with a plasma and if it receives glare probably an LCD. Most contrast ratios are crap plus thats not the most important thing that your eye should be looking for rather color accuracy is the most important as far as getting a realistic looking image. How far back are you going to be sitting? etc will also determine what I would recommend.

my tv is receiving direct glare. my family sits in various location i uploaded a rough sketch of the rooms windows and seats. the tv i am looking for is around 52"

Mmm just looking from your diagram you have almost all the light falling on top of your TV. The best image happens when NO light falls on your TV. (See my direct view vs projection post elseqhere for the discussion of the light phenomenon called flare (light falling on the image), which degrades the blacks and kills overall contrast). So in your current arragement the brightest the TV the better, to overcome the lrgth falling on it. But of course it would be easier if you rearranged things a little or did some light control to ensure the TV screen is in shadow. Your daylight viewing must be very different from your nightime viewing!

yes my viewing is very diffrent from day tonight but its not to bad with my tv. how are brightness levels rated? i have heard a bring diplays drightness was 480 nits for computer display tho"http://www.maximumpc.com/2006/06/toshiba_qosmio.html"

Brightness of a screen takes a couple of different terms so you would have to translate one into another from specs sheets if they are different (theres several web calculators to transform from candle/square meter (cd/m2), nits, lux, footLamberts, etc) (The SMPTE spec for CRTs for reference white was 35 footLamberts, but most consumer CRTs are set much brighter, etc). As for the relationship between brightness of TVs using the same terms, you get the same amount of brightness change going from 50 nits to 100 nits as going from 200 nits to 400 nits. (double the light) but going from 400 nits to 450 nits is basically imperceptible.. (Going from direct sunlight to overcast would be about the same amount of light change as going from 800 nits to 100 nits for example)

If your current TV looks acceptable on your viewing conditions you need one that's similar in brightness if not more. If you get a less bright one, you'd might have problems when the sun is high.
