Sharp Aquos LC-40D78UN LCD HDTV Review
Not the best budget TV we’ve reviewed, but it gets the job done for a reasonable price.
Motion Smoothness (6.00)
The Sharp LC-40D78UN didn't maintain particularly sharp lines during our motion tests. As a photo panned around the frame it lost a lot of its fine details: eyes smudged, the nose almost disappeared, and lips smeared quite a bit. Still, the overall image was legible and each individual shape in the photo was still legible, if a bit distorted. If you intend on hooking up your computer to this TV to look at family photos, make sure you aren't using transition animations.
Motion Artifacting (7.00)
The Sharp LC-40D78UN only had minor issues with motion artifacting. More on how we test motion performance.
3:2 Pulldown & 24fps
We saw some minor flashing in 3:2 pulldown mode, but overall the TV handled it well. Some fine, repeated patterns—like the backs of empty stadium seats—acquired a crawling effect. Other than these small problems, we didn't see any issues with 3:2 pulldown or 24fps mode. More on how we test 3:2 pulldown and 24fps.
Your TV won't always be displaying content in its native resolution. The Sharp LC-40D78UN is a 1080p TV, but any time you watch standard definition, DVDs, or broadcast HD, you're actually watching a lower resolution image that's been upscaled to fit the screen. This additional processing can cause some issues, but we didn't see any egregious artifacting on the LC-40D78UN. More on how we test resolution scaling.
The TV did well with 480p playback overall. We noticed a slight shimmery effect to some patterns and the focus was a bit soft, but otherwise the LC-46SB57UN did well with 480p content.
The TV had some trouble with 720p content. The biggest issue was with moire interference. We saw lots of plaid patterns and gradients forming where they shouldn't.
There were some minor issues with 1080i playback. We noticed a few patterns acquired a pale green hue, which is a common problem with interlaced processing.
