Overview

The LG 47LH90 arrived as LG's full-array LED flagship at a time when the technology was genuinely transforming flat-panel picture quality. Unlike edge-lit panels that push light from the sides and struggle with uniformity, the 47LH90 places LEDs directly behind the entire panel surface. Combined with a 240Hz TruMotion refresh rate and a 2,000,000:1 dynamic contrast ratio, the result is a set that renders fast motion without smearing and dark scenes with real depth — both meaningful upgrades for a living room anchored around sports, film, or gaming.

The physical design is clean and understated by the standards of its era — a dark bezel and slim-ish profile that suited the transition away from bulky CRT furniture setups. The Intelligent Sensor adds a layer of automatic optimization that most users simply leave enabled, letting the TV self-calibrate as room lighting changes through the day. The four-HDMI rear panel remains genuinely practical even by current standards. Where the 47LH90 shows its age is in the absence of any network capability, HDR support, or built-in streaming platform — all things that buyers in today's market would need to supplement with an external device. As a display engine it remains capable; as a complete smart-TV solution it requires additions.

Pros & Cons

👍 Pros

  • Full-array LED backlighting delivers more uniform brightness across the entire 47-inch panel compared to edge-lit designs.
  • 240Hz TruMotion refresh rate keeps fast sports and action sequences sharp and blur-free without ghosting artifacts.
  • Four HDMI ports cover a fully loaded entertainment center without requiring a switch box.
  • The Intelligent Sensor adapts picture quality to ambient light automatically, reducing eye fatigue across different viewing environments.
  • Built-in ATSC/Clear QAM tuner eliminates the need for a separate antenna box for over-the-air HD reception.

👎 Cons

  • As a 2009-era 1080p set, it predates 4K, HDR, and smart TV platform support — no streaming apps are built in without an external device.
  • At 47 inches, the set is large but its LED local dimming implementation from this generation is limited compared to modern FALD panels.
  • The 2,000,000:1 contrast ratio is a dynamic (not native) spec, meaning peak contrast requires the TV's dynamic contrast circuitry to be active, which can cause brightness pumping on some content.
  • No USB media playback or built-in Wi-Fi — connectivity is hardware-only through the four HDMI and legacy inputs.
  • Energy consumption of full-array LED sets from this generation is higher than equivalent modern panels.

Frequently Asked Questions

It virtually eliminates the motion blur you'd normally see during fast sports pans or action sequences. The TV interpolates extra frames between the source frames, so movement looks smoother and edges stay crisp — most noticeable during live sports or high-speed gaming.
Yes. The LG 47LH90's Intelligent Sensor reads ambient room lighting and automatically adjusts brightness and color temperature so the picture looks natural whether you're watching in a bright afternoon room or a dark evening setup — no manual trips into the picture menu required.
The 47LH90 provides 4 HDMI inputs, giving you enough ports for a Blu-ray player, game console, streaming box, and A/V receiver simultaneously without swapping cables.
Yes. The built-in ATSC/NTSC/Clear QAM tuners let you receive free over-the-air HD channels with an antenna, as well as unencrypted cable channels without a set-top box.
The 47LH90 has a 2,000,000:1 mega contrast ratio. In practice this means the TV can produce very deep blacks alongside bright highlights in the same frame, which adds perceived depth and realism to dark scenes like night sequences or space imagery.
