Is it reasonable to expect excellent white uniformity on a Sharp Elite? Excellent black uniformity? What are the odds for stuck or dead pixels? Your wisdom on this will be greatly appreciated.
I just replaced my Samsung UN55B8500 with the 60” Sharp Elite. The superior local dimming in the Elite is instantly apparent – blooming is almost never apparent, and the black uniformity across the whole screen is excellent. However, uniformity of whites (or even grays) is clearly inferior to that of my old Samsung.
Although very subtle and only evident on several limited areas of the screen, there’s a “window pattern” that becomes apparent on any evenly lit, homogenous color. Unfortunately, the areas with this problem are all in the top half of the screen, so it shows up frequently in skies. What I’m seeing is a bright grid of perpendicular lines framing slightly dimmer squares, each about the size of a large postage stamp. The architectural geometry of this pattern grabs the eye, making it difficult to ignore once detected. (I’ve wondered if it's related to the layout of the LED backlights.)
There are also two narrow bands that, on any image of uniform color and intensity, are noticeably brighter than the surrounding screen. (The color temperature actually seems altered on these bands.) One of these runs across the whole screen horizontally, almost dead center. The other runs vertically, just to the right of center. These become apparent when pans or tilts move across uniform, evenly lit surfaces.
As far as I can tell, the panel also has 3 dead pixels (or sub-pixel elements), and one stuck pixel. I'm able to ignore these as all are off center. Is this common to this product?
I’ve got just one day left within my 30 day return or exchange window, and am considering both. I don’t see either of these artifacts on the display model at the store. However, the display model has noticeably lighter blacks than mine (even when I adjust it to match my settings).
We all like perfection, but every technology demands some compromise. What’s been your experience? Does your set deliver deep and uniform blacks? (Someone commented that they went from a 70 to a 60 and were disappointed with the blacks on their smaller set.) How is panel uniformity on bright screens? Does anyone else see this “window pattern”? Please let me know. I’d like to make an informed decision before I gamble on an exchange.
