Christmas sale, or After Year's End sale?

Blanka:
To cross a certain width, 1/30th of the length is needed in height to have a decent stiffness. Those 1m/1cm TV's cant be made stiff. I don't do anything with them, but it just feels awkward. And 1 cm means NO CCFL.... so I'll pass.

Gray_Area:
Regarding contrast and black levels, I've read it goes LCD CCFL, LCD LED edge-lit, LCD LED.

Mainly, this display will be for watching movies (DVD/Netflix-streamed/HDD). Depending on the black levels, I may play retro games on it.

Blanka:
The panel is the only defining thing in black levels, and not much has gained last few years. With some newer LED-panels, you have things like local dimming, but that does not improve much. Your Pac-man is not going to gain contrast with that. But the black bars on the sides will look blacker. If that is OK, go ahead, go for local dimming LED. If you want great pixel-to-pixel contrast, just read the tests and the real world measurements. At the moment 1:3000-1:3500 is about the highest you can get from LCD. I have a 2008 wide gamut PVA-panel 27 inch 1920x1200 pixels, with 1:1500 static contrast, and I can tell you, it is about the best panel ever made in terms of contrast and colour space. They don't make 'm like that anymore :). The thing goes up to 550cd/m2 (twice as much as most LED panels!), LED tv's look pale next to it and black stays black.

On the other hand, I also have a lightning fast 1:800 static 26 inch IPS screen, and that looks as good. As long as the brightness is set-up at the right level relative to the ambient light, even 1:600 can be more than enough.

just to throw a wrench into the works, i just picked up a 42" philips plasma (1080i) for $150. it was my sister-in-laws, it had a few bad caps in it, replaced them, fired right up.

swapped it for my 50" hitachi Rear projection LCD (50VS69) it's 1080i as well, the same weekend the plasma crapped out, my bulb blew (good timing)

now iv'e noticed 2 things, yes plasma is ridiculously bright and the blacks are spectacular compared to my RP but the color gamut is not as good. RP display has nice and smooth gradients.

graidents look a little banded on the plasma, where they look fine on my RP  :dizzy: there is a slight issue with image retention a people say with plasmas (i do game on my TV) but nothing that i could consider an issue just yet. I don't get that at all with my RP.

granted my RP was the top of the (for the end of the) line when it comes to RPTV's (has separate panels for RGB in the light engine instead of using a color wheel and a single panel nets great colors) but you'd think something newer would look a little better.

the only disadvantage to my RP is the poor viewing angles... not that i sit anywhere but center stage when playing games.  :cheers:

I'd have to say that when my replacement bulb shows up, it'll be going back in it's place. maybe i'll have a 42" monitor for my computer.

Turn that around:
LCD>LED>Plasma.
BTW, LED is as much LCD as LCD :). It just has different (read inferior) backlighting.
Give me a wide gamut CCFL backlit LCD any time. Don't give ---steaming pile of meadow muffin--- about 8cm thickness on a 1m diagonal TV.
Those last generation Samsung and LG ones with Full HD, 1:3000 static contrast and wide-gamut CCFL beat the ---steaming pile of meadow muffin--- out of any modern flimsy LED piece of crap.

The backlighting IS the difference.  LCDs use a flourescent tube, which gets hot, draws a lot of power and "yellows" the colors just a tad.  The power drain puts stress on the power supply and the main cause of fault in modern tvs are bad caps on the ps.  Leds use white leds to backlight the panel for a superior color scheme and a lot less power.  The thickness of the screen doesn't really equate into it. 

I'll throw this example out there:

Take a look at a really nice xmas light display that uses white mini blubs.  That is white right?  It is beautiful right?  Now take the same display and replace some of the mini bulb strings with identical looking strings of mini led blubs.  Suddenly you realize the thing you once thought was beautiful is a yellow dog turd. 


Now do I think the difference is enough to justify the extra cost?  No not yet.... those things need to come down a bit or you need to find one on sale.  There is a farily striking difference though.  LCDs are the sweet spot atm.... that doesn't mean they are the best, but they are certainly the best value.


lilshawn:  A lcd-based RP is a equivelent of lcd tv... it just uses projection tech.  RP is a VERY good display, but as you've noticed having to replace bulbs and poor viewing angles tend to put it in another category.  I would have mentioned what you did about plasmas (poor color range) but if it was coming from me people wouldn't have believed it.  So thanks.  ;)
