Overview

The Sony BRAVIA KDL40EX520 is a 40-inch Full HD LED television from Sony's 2011 lineup, designed to bring quality 1080p viewing to living rooms, bedrooms, and offices. Its edge-lit LED backlighting produces a bright, vivid picture while keeping the chassis slim and energy consumption lower than traditional CCFL-backlit LCD panels. The 1920 x 1080 resolution ensures crisp detail for Blu-ray movies, broadcast television, and streaming content, making it a capable display for everyday entertainment at this screen size.

On the connectivity front, the KDL40EX520 is well-equipped with four HDMI inputs, two USB 2.0 ports, component and composite video inputs, and both digital and analog audio outputs. The built-in Ethernet port enables wired internet access for the integrated smart TV platform, which provides direct access to Netflix, Hulu Plus, YouTube, and Pandora. For wireless connectivity, the TV requires an optional Sony USB Wi-Fi adapter. While the smart platform reflects its 2011 vintage and no longer receives app updates, the generous HDMI port count means a modern streaming stick or set-top box can easily fill that gap, extending the TV's usefulness as a reliable Full HD display.

Pros & Cons

👍 Pros

  • Four HDMI inputs provide ample connectivity for multiple devices without needing to swap cables.
  • Edge LED backlighting offers improved energy efficiency and a slimmer profile compared to CCFL-backlit LCDs of the same era.
  • Full HD 1080p resolution delivers sharp, detailed picture quality for a 40-inch screen size.
  • Built-in streaming apps allow direct access to Netflix, YouTube, and other services without an external device.

👎 Cons

  • Wi-Fi requires a separate USB adapter purchase, as the TV only has Wi-Fi Ready support and not built-in wireless.
  • The 60Hz native refresh rate may produce noticeable motion blur during fast-paced sports or action content.
  • As a 2011 model, the smart TV platform has a limited and outdated app selection that no longer receives updates.
  • No 4K resolution support, which limits future-proofing as content increasingly shifts to Ultra HD.
