Default Re: Which is better LED-DLP or LCD?

Loaded question. and no simple answer..

The only manufacturer of LED based DLP's is Samsung.

Their current model line is the HL-??A750 line (the 650's are lamp based models)

in the A750 line: its available in 61 and 67 inches. The only difference is screen size.

between the 07' and '08 models, there are really only a small number of changes.
  • 2nd generation phatlight LED engine (little brighter, and other minor tweaks)
  • 1080p support
  • slimmer cabinet
  • A few menu option changes (and default setting changes)
  • 07 models had 56 and 61 inch, 08 has 61 and 67 inches (brighter LED's)

Note: the A750 line has no color wheel. That's for all the white light lamp based units.
The Lamp based units are cheaper to buy (not so much anymore), but much more expensive to operate day to day (check the operating power consumption), and will need a lamp replacements every 1-2 years (at $400 each) and the lamps are HOT. Higher AC bills.

The biggest decision between the two technologies is the cabinet.
Are you willing to have a big box (rear projection DLP) or do you demand/need the 2-3 inches for a wall mount?
(IF you plan of standing on a table/shelf, its irrelevant. Just "but its thin' bragging rights)

Conversely, Flat panel, wall mountable LCD's:
Dozens of manufacturers make them, with dozens of options, each model with its own strengths and weaknesses. LED back lighting for LCD displays are the new thing coming.
(There are so many LCD options, that you could not keep a web site accurate)

I personally have chosen the Samsung 61A750 LED DLP.

my reasoning:
  • Cost factor: 61 inches for about $1800 ($300 more = 67 inches)
  • Cost factor: changing technology means probable replacement within 4-5 years anyway.
  • Fantastic picture
  • 1080P
  • HDMI 1.3 support
  • No lamp to replace
  • no screen-door effect (DLP wobbulation)
  • Space considerations (its fits well in my 15x20 family room)
  • Size: I want a LARGE screen and quality LCD and Plasma in 60+ inches is far outside my budget. (I considered front projection, but the daytime weakness put me off)
  • good contrasts (even in day)
  • more eco-friendly (no plasma gas. less/smaller parts than big LCD's)
  • Efficient power usage to lamp units or plasmas. (Cheaper to run)
  • Serviceable: the light engine (chip) and the DLP chip are actually small solid state components
  • Zero moving parts
  • pleased user base
  • No burn in concerns
  • underlying high frequency of pixel updates (smoother picture IMHO)
  • LCD and Plasmas are more fragile.

  • LCD's fade over time. To fix it, you effectively replace the entire unit. (aka: nearly un-serviceable)
  • When individual pixels go out, you need to have a MAJOR $$ service, or replace the unit
  • LCD's are fragile and heavier, especially in larger sizes

here is a great thread on the AVS forum dedicated to the A750 line

its 200-300 pages of happy users.

one more reminder.

An HD TV needs good HD sources to shine. (as well as all the other HD Audio components)

Many cable/Sat providers are over compressing the signal to the point that it barely qualified as HD anymore. (comcast, DirectV, and too many others)

Verizon FIOS shines in this regard.

Blu-Ray: very title specific. It all depends how how well they made the disk and the original source. Some new disks are no better than their older DVD cousins.

Welcome to the HD addiction.

Say goodbye to your spare $$$.
