Tv 32"

Una solución práctica para previsualizar también en sets.
 
Contrast Ratio
Contrast is by far this Samsung's biggest flaw. Using the standard ANSI checkerboard (in Movie mode), I measured plenty of brightness with a reference white of 200.20 cd/m2 , but a rather poor black level of 0.169 cd/m2 , giving the J4000 a contrast ratio of 1185:1. This isn't absolutely terrible—in fact, it's in line with last year's H4000—but it compares unfavorably to similarly priced competitors.
Viewing Angle
Horizontal viewing flexibility is one of this TV's best areas. Measuring in 10° arcs from the center to the side of the screen, we examine contrast integrity and more and more obtuse angles, capping a TV's viewing angle once its contrast result falls below 50% of the original, head-on value. The J4000 tested with a total viewing angle of 81°, or ±40.5° from the center to either side of the screen. This isn't quite as good as last year's H4000, but it's amply good for a 32-inch TV.
Color Gamut
There's no way to adjust the J4000's color (short of hacking into a secret menu, or adjusting the extremely coarse "Color" control), so what you get in Movie mode is what you're stuck with. Fortunately, the TV boasts fairly accurate colors overall, with a bit of oversaturation in green and a bit of skewing in blue, but nothing so bad that most viewers will have reason to complain. The white point is also very accurate—in fact, it's less blue than a few much more expensive televisions.
Grayscale & RGB Balance
The J4000 has solid grayscale tracking for a budget TV. The big problem with grayscale is that it's rarely gray in reality—TVs, who use additive color, like to make it blue, peach-tinted, or sometimes even green. Visible (or close to visible) error in the grayscale is measured in a collective called deltaE, where a deltaE of 3 or less is ideal (and, arguably, perceptibly perfect).
At an out-of-the-box dE of 3.54, the J4000 doesn't produce a perfect grayscale, but it's close enough to the limit of imperceptibility that you'll never notice a thing, especially at this screen size and resolution.
If we take a closer look at the underlying (additive) RGB emphasis that makes up the J4000's grayscale production, we can see that while it's not as evenly emphasized as it could be (with each line at 100% emphasis), the discrepancies are all within a range of 10% or less, which is quite good, especially in this price range.
Gamma
The J4000 tested with a gamma sum of 2.23, which is quite close to the 2.2 "normal lighting" standard. It's a bit bright coming out of black and really closer to a flat 2.3—which is Samsung's standard, generally—meaning it's well-suited for rooms with some or normal amounts of ambient lighting.
