Overview

The LG 75NANO90UPA is built around the premise that a living room TV should require almost no configuration to look great. The NanoCell panel filters impure light wavelengths at the pixel level, producing cleaner primary colors than standard white-backlit LED displays — a difference that's immediately visible in saturated content like nature documentaries or animated films. Pair that with Full Array Dimming for improved contrast and Cinema HDR support including Dolby Vision IQ and Dolby Atmos, and you have a home theater package that justifies the 75-inch footprint.

The a7 Gen 4 AI Processor is the operational core — it continuously analyzes content type and adjusts both picture and sound parameters in real time, including AI 4K Upscaling for non-native content. ThinQ AI extends the TV's usefulness beyond entertainment into smart home management, with the Home Dashboard serving as a central control interface for compatible devices. At 120Hz native refresh with TruMotion processing, it handles fast content cleanly. The primary trade-off is brightness — at 250 nits, this TV is optimized for controlled lighting environments rather than bright open-plan rooms.

Pros & Cons

👍 Pros

NanoCell panel delivers significantly wider color gamut than standard LED TVs, making HDR content noticeably more vivid
a7 Gen 4 AI Processor automatically optimizes picture and audio settings per scene — a genuine quality-of-life upgrade over manual calibration
Full Array Dimming improves contrast by locally controlling backlight zones, producing deeper blacks than edge-lit alternatives
Built-in Google Assistant and Alexa eliminate the need for a separate smart speaker to control the TV or connected home devices
75-inch screen size combined with TruMotion 240 processing makes fast-paced sports and gaming content look exceptionally fluid

👎 Cons

Full Array Dimming zone count is not disclosed, so blooming around bright objects on dark backgrounds can still appear in some scenes
250-nit peak brightness is modest for a 75-inch TV — the NanoCell panel performs best in dim or controlled-light rooms, not sun-drenched spaces
The webOS interface can feel sluggish when navigating multiple apps simultaneously compared to Roku or Fire TV platforms
At 75 inches, this TV requires substantial wall reinforcement or a purpose-built stand — logistics and mounting costs add up
NanoCell technology does not achieve the deep blacks of OLED, which is a measurable gap in perceived contrast in dark room viewing

Frequently Asked Questions

What makes NanoCell different from a standard 4K LED TV?

NanoCell technology uses nano-sized particles to filter out impure colors, producing more accurate and vivid reds, greens, and blues than conventional LED displays. The result is noticeably richer color saturation, especially in wide-angle viewing situations where standard IPS panels tend to wash out.

Is the 120Hz refresh rate real, or is it an effective rate from motion processing?

The panel uses TruMotion 240 processing to reach an effective 240fps equivalent, but the native refresh rate is 120Hz. For gaming and fast sports content, the native 120Hz panel delivers genuinely smoother motion than 60Hz alternatives.

Can this TV work as a smart home hub, or does it just support voice assistants?

It goes beyond simple voice assistant support. ThinQ AI's Home Dashboard lets you monitor and control compatible LG and third-party smart home devices directly from the TV's interface, in addition to Google Assistant and Alexa voice control.

Does Filmmaker Mode affect all content, or can I toggle it per source?

Filmmaker Mode is selectable per content and can be triggered automatically by supported streaming services. It disables motion smoothing and post-processing overrides to display the director's intended frame rate and color grading.

What streaming services are built into this TV without additional hardware?

Netflix, Prime Video, Apple TV+, Disney+, and LG Channels are all built in alongside the full webOS smart platform, which includes a broad app library. No streaming stick or box is required.
