Overview

The Sharp LC-70LE857 is a 70-inch LED television from Sharp's Aquos lineup, built around the company's proprietary Quattron display technology. Where conventional LCD panels use three sub-pixels per pixel (red, green, blue), Quattron adds a fourth yellow sub-pixel to expand the color gamut and improve accuracy in tones that RGB struggles to reproduce faithfully. Combined with 1080p resolution and a 240Hz refresh rate, the panel delivers vivid color and smooth motion handling that serves movie watching and live sports particularly well on this large canvas.

The LC-70LE857 also supports active 3D via Bluetooth-synced shutter glasses, with two pairs included in the box for immediate use. The built-in audio is a genuine differentiator — a 35W system with an integrated subwoofer produces fuller, more dynamic sound than the thin speakers found in most flat-panel televisions, making it a viable standalone audio solution in bedrooms or smaller living rooms. Smart TV functionality is provided through Sharp's SmartCentral interface powered by a dual-core processor, and connectivity includes 4 HDMI inputs, 2 USB ports, and both Wi-Fi and Ethernet networking. Buyers should note that while the TV's display and audio capabilities remain strong, the smart platform is dated and an external streaming device such as a Roku, Fire TV, or Apple TV is recommended for access to current apps and services.

Pros & Cons

👍 Pros

  • 70-inch screen provides a genuinely cinematic viewing size for movies, sports, and gaming.
  • Quattron four-color pixel technology expands the reproducible color range beyond standard RGB panels.
  • 240Hz refresh rate with motion processing reduces blur during fast action and sports content.
  • 35W speaker system with subwoofer delivers substantially better built-in audio than most TVs.
  • Four HDMI inputs accommodate multiple source devices without switching.

👎 Cons

  • 1080p resolution on a 70-inch panel produces lower pixel density than a 4K display at this screen size.
  • The SmartCentral platform is outdated and many modern streaming apps may not be supported.
  • Active 3D requires battery-powered glasses and 3D content availability has largely diminished.
  • Built-in Wi-Fi is limited to 802.11n speeds, which may bottleneck high-bitrate streaming.
  • The panel's size and older LED backlighting technology result in significant power consumption.

Frequently Asked Questions

Quattron adds a yellow sub-pixel to the standard red, green, and blue pixel structure. Sharp designed this to reproduce a wider range of colors, particularly golds, brass tones, and cyan shades that conventional RGB panels approximate less accurately.
