Sony BRAVIA BX420 Series

  • 32" 1080p LCD

#1 in LCD Sony TVs
Released February, 2011
Sony eschews the transparent edging, color accents and swivel stands of Samsung and LG in favor of unadorned glossy black on a low-profile, swivel-free base.

The BX420 is Sony's least expensive 1080p TV for 2011, and it's a very good value.

We performed a hands-on evaluation of the 40-inch KDL-40BX420, but this review also applies to the other screen sizes in the series.

Despite handling the full resolution of 1,920x1080 pixels, it evinced softness in text and other detailed areas that no adjustment we tried could cure.

Interestingly the significantly more expensive Sony EX720 was visually indistinguishable from the BX420 in terms of the two TVs' depth of black.

We'd give the BX420, with its more accurate color and better processing, a slight edge over the Samsung LND550 with its better black levels and uniformity, but the two are neck-and-neck overall.

While the LG and Vizio were both technically more accurate, we preferred colors on the BX420 since (thanks to its better black levels) it looked punchier and more saturated.

When seen from off-angle it performed better than the Vizios at keeping its black level preserved, but not as well as the Samsungs, and we detected more reddish and bluish discoloration than on the other displays.
BRAVIA BX420 Series by c|net (Oct, 2011)
Its worst offense is color inaccuracy in dark areas and imperfect screen uniformity, but its black levels were decent and it actually handled 1080p/24 cadence-something we didn't expect from a 60Hz TV.

Unlike the Samsung LND550 series, the BX450 lacks an Ethernet port, so it can't do the same via DLNA over a home network.

Ports

Two HDMI might be enough for the most basic systems, but to add something beyond a cable box and a game console-say, perhaps, a Roku or even a temporary camcorder or laptop PC connection-you'll need to get an external HDMI switch.

Two HDMI inputs is a paltry amount by even entry-level standards these days.
Sony BRAVIA BX420 Series 32" | Rated 63% by by c|net (Oct, 2011)
The BX420 performed worse as a big PC monitor via VGA than most LCDs we've tested.

Video

We selected Cinema as the best picture setting for dark-room viewing out of the box, although it measured too red with dim light output and dark gamma.
Sony BRAVIA BX420 Series 32" | Rated 63% by by c|net (Oct, 2011)
We're guessing the TV isn't performing 2:3 pull-down processing when it detects a 1080p/24 source, which may lead to some artifacts, but we didn't notice any during our testing.

We were surprised that the Sony, a 60Hz TV, passed our 1080p/24 test by preserving the cadence of film.

Panel

The CCFL (cold-cathode fluorescent) backlight that illuminates this TV's LCD panel is slowly going extinct, replaced especially in larger screen sizes by LEDs packed into razor-thin cabinets that can generate more light from less power.

Content

That's why we recommend that BX420 owners use the 1080p/24 setting on their Blu-ray players.

PC sources via HDMI looked fine, however.
