LG LK450

  • 37" 1080p LCD

The screen of the LK450 didn't have any of the bright spots we saw on the Sonys, maintaining its brightness and color well across its surface.

Features Key features of the LG LK450

Back view of LG LK450
The LG's Cinema mode provided the best picture before any tweaking, although it was quite dim (about half of our target 40 fL luminance) with bright gamma and a bluish-green color temperature.

We performed a hands-on evaluation of the LG 42LK450, but this review also applies to the other screen sizes in the series.

The rest of the sets in the lineup also have matte screens, and in general they all performed equally well in this category.

black levels

Samsung 550 Series (2011 LCD)
Accuracy isn't everything, however, and the LG's poor black levels made its colors appear more washed out, desaturated, and worse overall to our eyes than most of the others.
LK450 by c|net (Nov, 2011)
As usual dark areas, like the letterbox bars and the black walls of the courthouse in Chapter 13, for example, showed the biggest differences; in the LG's case these areas appeared washed out and significantly less realistic than on any of the other sets.

contrast ratio

Samsung 550 Series (2011 LCD)
From off-angle its blacks washed out quicker than any of the others, but on the flipside we didn't see as much discoloration as we did on the Samsungs and Sonys.
LK450 by c|net (Nov, 2011)
The LG LK450 delivered a worse picture than its Sony and Samsung entry-level competitors, a showing that can be blamed squarely on light black levels (which get worse than usual for off-angle viewers).

Unlike the Samsung LND550 series the LK450 lacks an Ethernet port so it can't do the same via DLNA over a home network.

Video

The LK450 delivers more connections than just about any other entry-level TV, with a second component-video slot and a headphone jack being the standouts.

Like the BX420 the LG actually passed our 1080p/24 test by preserving the cadence of film.
LG LK450 37" | Rated 56% by by c|net (Nov, 2011)
In the LG's case we had to engage the Real Cinema option; leaving it set to Off causes the characteristic stutter of 2:3 pull-down.

Type

Measurements of the LK450 proved it delivered the most accurate color in our lineup, and its advantages over the plasma, the Samsung LND550 and, to a lesser extent, both Sonys, was visible in most scenes.
LG LK450 37" | Rated 56% by by c|net (Nov, 2011)
Such objects appeared dimmer and much less distinct, and thus less distracting, then they did on the Panasonic plasma, for example, and black levels were also preserved better.

Panel

Like most standard LCDs we've tested the LK450 is more of a hog than LED-based models, yet efficient enough that its yearly power toll would barely cover lunch for two.
LG LK450 37" | Rated 56% by by c|net (Nov, 2011)

Content

Since the LK540 can take advantage of it, we recommend its owners use the 1080p/24 setting on their Blu-ray players.

Ports

Via VGA the LK450 passed our PC test, delivering full 1,920x1,080-pixel resolution, but we did see some edge enhancement (ringing appearing around some objects) that we couldn't quite defeat, despite trying for awhile with the two sharpness controls in the Expert menu.
