Overview

The Sharp AQUOS LC46D78UN is a 46-inch LCD television built around a Full HD 1920x1080 panel that delivers crisp, detailed images across a wide screen. Its 120Hz Fine Motion Enhanced technology interpolates additional frames between the source content, resulting in noticeably smoother motion during fast-paced sports broadcasts, action films, and video games. The 4ms response time further contributes to clean transitions, while the 176-degree horizontal and vertical viewing angles ensure that the picture remains consistent whether you're sitting directly in front or off to the side.

Connectivity is well covered with three HDMI inputs, two HD component inputs, two composite video inputs, and a 15-pin D-sub PC input, making it straightforward to connect a variety of entertainment and computing devices. The built-in ATSC, QAM, and NTSC tuners allow reception of over-the-air and unencrypted cable signals without additional hardware. While the CCFL backlight system adds some depth and weight compared to modern LED-backlit sets, the trade-off is a mature, proven display technology that produces even illumination across the panel. At roughly 44 inches wide and just under 48 lbs with the stand, it fits comfortably on a media console or can be wall-mounted for a cleaner look.
