Comparison models (details)
Samsung LN46D630 46-inch LCD
Samsung UN46D6400 46-inch edge-lit LED
TCL L40FHDF12TA 40-inch LCD
Panasonic TC-P50UT50 50-inch plasma
Sharp LC-60LE640U 60-inch LED
Samsung PN59D7000 (reference) 59-inch plasma

Black level: The UNEH6000's shade of black was lighter (worse) than that of any other TV in our lineup outside the TCL. In the black areas and letterbox bars of dark scenes, like the Central Park nighttime metal detector hunt from "Extremely Loud and Incredibly Close" (5:50), both of the other Samsung LCDs -- including the edge-lit UND6400 and the CCFL-based LND630 -- were visibly superior, as was the Sharp. The plasmas, as expected, looked better still.

Shadow detail was mostly hit with the occasional miss. The checks on Oskar's shirt in that scene, as well as the shadows on his jacket, looked as natural as on any of the sets in the room if you ignored the lighter black levels. On the other hand, in even darker scenes, like the pan over the trees a bit earlier (5:25), details like the darkest leaves and branches were invisible; again only the TCL's shadows looked less natural.

Beyond those light blacks, the UNEH6000 has another issue. Its backlight also had an annoying tendency to flash on and off when displaying a black screen, an issue that was distracting to say the least when it happened in the middle of watching a movie. I saw such flashes at 12:10 in "I Am Legend" when Robert closes up his house, for example, and I'm sure they'll also appear in other midmovie fades to black.

Color accuracy: This category was definitely the UNEH6000's main strength. Its accuracy came closest to the color reference among the TVs in our lineup in both brighter scenes, like Oskar's interaction with his father in the shop (6:35) and the faces of the schoolkids heading home (9:48), and in darker ones. Its advantage in maintaining proper saturation in dimmer scenes over the non-LED LND630 was particularly obvious at 11:50, where Oskar's shadowed face looked much too ruddy on the LND630 and quite natural on the EH6000.

As usual for a TV with light black levels, however, saturation and richness on the EH6000 was subpar in comparison, so despite their accuracy, colors weren't as pleasing to watch as on the better displays.

As usual for an LCD TV, the EH6000's color near black got significantly bluer than on the plasmas, and its lighter black levels exacerbated the visibility of the color shift. Only the TCL's black bars and deep shadows looked less accurate.

Video processing: The UNEH6000 series has most of the same processing options found on higher-end Samsungs, and when it comes to dejudder it offers more adjustability than the competition. Its three dejudder presets -- Clear, Standard, and Smooth -- join a Custom setting under the Auto Motion Plus (AMP) menu. Engaging Standard and Smooth introduces the characteristic smoothing effect, as well as some artifacts, so I preferred the freedom of Custom.

That mode, which includes a Blur Reduction and a Judder Reduction setting, lets you tweak both parameters to your liking. I prefer minimal dejudder, but having the option to dial in as much or as little as you like is very welcome.

In the AMP menu at Custom with Judder Reduction at 0 and Blur Reduction at 10, the UNEH6000 offers the best of both worlds. It turned in its full-motion resolution and handled 1080p/24 properly. With AMP set to Clear or Off, the set seemed to be treating the image with 2:3 pull-down, showing the slightly stuttering cadence seen on 60Hz models. The other AMP settings introduced more smoothing/dejudder.

Unlike some Samsung TVs the UNEH6000 failed to properly deinterlace a 1080i signal no matter which Film mode setting I used, so you may see some minor artifacts in film-based TV material at that resolution.

I measured much better motion resolution (1,080 lines versus about 600) when I turned on the backlight scanning feature, labeled LED Motion Plus. Unfortunately doing so dimmed the picture too much, so I left it off. As usual I had difficulty discerning any difference in motion resolution with program material, as opposed to test patterns, regardless of the setting I chose.

Uniformity: My UNEH6000 review sample didn't suffer from brightness variations across the screen. In test patterns the sides appeared a bit brighter than the middle, and the bottom edge was brighter still, but these issues were invisible in most program material. I did notice some very faint backlight structure that looked like vertical bands in flat fields, such as the blue sky behind the opening scene from "Extremely Loud & Incredibly Close," but again it was quite minor.

On the other hand, the EH6000's fidelity from off-angle was among the worst in the lineup. It lost color and black-level fidelity rapidly when seen from just a seat cushion to either side of the sweet spot in the middle of the screen. The other LCDs weren't great either, but even the lowly TCL looked slightly better from off-angle than did the Samsung UNEH6000.

Bright lighting: I appreciated the matte screen in bright lighting since it reduced reflections much better than the glossy finish on the Panasonic plasma and the Samsung UND6400. Compared with the other LCDs, which all have matte screens, reflections were a tad brighter on the UNEH6000. The UNEH6000 also preserved black levels better than the Panasonic and worse than the UND6400; there was little difference I could discern between it and the other matte LCDs in this area.

Power consumption: I was curious whether the full-array LED lighting scheme affected power use compared with other backlight designs, namely edge-lit LED and CCFL, and the answer is "not much." As you can see below, like-size Samsungs used about as much juice regardless of backlight scheme, and while edge-lit LEDs from a couple of other brands were a bit more efficient, it only amounts to a few bucks per year. [(The wattage and dollar amounts apply only to the 46-inch size in the series.)
