Formats

The Sharp LC-40D78UN is a 1080p HDTV. That means you'll be getting the highest resolution picture that's currently available: 1920 x 1080 pixels. The next step for resolution is 4000 x 2000, but those panels aren't available yet.

Viewing Angle

Once you get about 20° away from sitting directly in front of your LC-40D78UN, you'll only see about half the TV's maximum contrast ratio. That's not a great viewing angle, even for an LCD. On the graph below, the Vizio is closer to the average viewing angle for LCDs, which is about 30°. Today's plasmas have viewing angles that almost allow you to view the screen from a perpendicular angle.

Reflectance

External light shining on the Sharp LC-40D78UN will result in a large, diffuse glow. On most TVs, that wouldn't be a problem, but the LC-40D78UN's weak brightness output isn't enough to overpower the shine. Basically, we really wouldn't recommend putting your LC-40D78UN in a room with a window or a light source you can't easily switch off.

Video Processing

The Sharp LC-40D78UN has a few processing features. We've listed them below, with a description of what the manufacturer thinks the features do and what we think they do. Interestingly enough, the manual both offers a broad description of the feature, then further clarifies by offering descriptions of the "on" and "off" settings.
