Television And Movies
My review session began with some staple DVD demos. To test the TV’s deinterlacing and upconversion of 480i sources, I fed it the Coliseum flyover in chapter 12 of Gladiator (DreamWorks Home Entertainment). Through the component video input, the WD-57833 did a fine job on the deinterlacing end, creating only minor shimmer. It didn’t do as good a job with my torturous Venetian-blind test in chapter four of The Bourne Identity (Universal Home Video), producing clear artifacts. With both discs, the level of detail was good but not exceptional. So, while it isn’t mandatory, you might want to mate the TV with a good progressive-scan or upconverting DVD player. In other respects, both discs offered generally natural skin tones, rich colors and a nice level of contrast.

Next, I tested the TV’s bit depth, or ability to render all of the steps between black and white, using scenes from chapter 10 of Ladder 49 (Buena Vista Home Entertainment) and chapter five of “The Whole Truth” episode of Lost’s second season (Buena Vista Home Entertainment). In both cases, light-to-dark transitions were mostly smooth, but there was still a lot of digital noise hanging over darker scenes – more so through HDMI than component video. Setting the noise-reduction control to High eliminated a lot of the noise without diminishing detail; however, it also introduced a new problem, a kind of image smearing or tracing during motion pans in dark scenes. I found that the Low noise-reduction setting struck the best balance, eliminating a fair amount of noise without adversely affecting motion. The opening scene of The Bourne Supremacy (Universal Home Video) showed the WD-57833 to have good black detail, and the black level, while a little gray, was deep enough to help the image retain solid saturation in a dark room.

When moving up to high-definition DVD sources, I first used my HD HQV Benchmark Blu-ray test disc (Silicon Optix) to make sure that the WD-57833 correctly deinterlaces 1080i and picks up the 3:2 sequence in film-based sources. The TV passed these tests through both the component video and HDMI inputs, and it created minimal jaggies in the disc’s moving-diagonal test. That means you don’t have to mate the WS-57833 with a 1080p player; you can mate it with a 1080i player and enjoy an image free of artifacts. If you do purchase a 1080p player, the WD-57833 accepts both 1080p/24 and 1080p/60 through its HDMI inputs.

Obviously, the step up to high-def DVD provided a step up in overall picture performance. The Kingdom of Heaven (Twentieth Century Fox Home Entertainment), Black Hawk Down (Twentieth Century Fox Home Entertainment) and The Prestige (Buena Vista Home Entertainment) BD discs all had very good detail and a generally clean presentation, although they too benefited from keeping the noise reduction at the Low setting. Dark, complexly lit scenes from chapter three of Mission Impossible II (Paramount Home Entertainment) and chapters two through four of Pirates of the Caribbean: The Curse of the Black Pearl (Buena Vista Home Entertainment) had solid black detail, but overall black level was only average, and the WD-57833 didn’t render the subtle shading and finest nuances that truly distinguish a high-end display.

I preferred Mitsubishi’s Smooth 120Hz mode to the 120-Hz implementations I’ve seen thus far in LCD TVs. When engaged, the feature made precise details more apparent in moving test patterns on the FPD Software Group Blu-ray test disc, as well as in basketball and football HD broadcasts. However, it did not dramatically alter the character of film sources, creating movement so smooth that it looks like video – a complaint I have with the 120Hz LCDs I’ve seen.

Brighter HDTV content is definitely the WD-57833’s strong suit. Its good detail, ample light output and vibrant colors breathed life into HD sporting events, nature shows and other bright content, all of which had a nice level of detail. Upconverted SDTV shows looked fairly detailed, as well. Again, though, the TV’s 480i deinterlacing isn’t entirely consistent, so you might want to let your cable or satellite receiver do the conversion. The WD-57833’s screen uniformity is solid; there’s no distracting hot spot in the center of the screen, and the viewing angle holds up well as you move off-axis.
