I am not impressed for the price - seems more like a gimmick than a real improvement.]]>Nov 20th 2007 1:11PMhttp://hd.engadget.com/2007/11/20/samsungs-led-backlit-ln-t4681f-lcd-hdtv-gets-reviewed/http://hd.engadget.com/2007/11/20/samsungs-led-backlit-ln-t4681f-lcd-hdtv-gets-reviewed/Nov 20th 2007 4:34PMhttp://hd.engadget.com/2007/11/20/samsungs-led-backlit-ln-t4681f-lcd-hdtv-gets-reviewed/http://hd.engadget.com/2007/11/20/samsungs-led-backlit-ln-t4681f-lcd-hdtv-gets-reviewed/Nov 20th 2007 5:08PMhttp://hd.engadget.com/2007/11/20/samsungs-led-backlit-ln-t4681f-lcd-hdtv-gets-reviewed/http://hd.engadget.com/2007/11/20/samsungs-led-backlit-ln-t4681f-lcd-hdtv-gets-reviewed/Nov 21st 2007 11:14PMhttp://hd.engadget.com/2007/11/20/samsungs-led-backlit-ln-t4681f-lcd-hdtv-gets-reviewed/http://hd.engadget.com/2007/11/20/samsungs-led-backlit-ln-t4681f-lcd-hdtv-gets-reviewed/
The matrix of LED's in the backlight panel are individually brightened or dimmed (or turned off) to suit the image. The contrast ratio is amazing. This is far superior to previous backlight dimming methods where backlight brightness could only be controlled in relatively large zones of the screen, where the dimmed backlights could not be turned completely off.

I intended on buying a 46" Sony Bravia today, but after seeing the Samsung and looking at everything else at BestBuy, I bought the Samsung. Being able to turn off the LED's gives it a contrast ratio of 500,000:1 ... as listed in the store, but the number didn't matter, the blacks on all the other TV's were distinctly grey in comparison, even when standing a few TV's down the line, comparing other brands while looking back at an angle to the Samsung.

The black band above and below a wide format movie was indistinguishable from the black of the frame, while the same band was clearly glowing on all the other TV's.

To say this TV can't produce accurate shadows or blacks is to expose your total ignorance. Go see for yourself, then come back and apologize for embarassing yourself here.
