Overview

The LG 75UM7570 delivers 4K UHD resolution (3840×2160) across a 75-inch panel, a size where the jump from 1080p to 4K is genuinely visible at typical 8–12-foot viewing distances. The Quad Core processor handles scene-by-scene HDR tone mapping and real-time upscaling of lower-resolution sources — meaningful on a panel this large, where upscaling artifacts from 1080p streaming or broadcast content are more visible than on smaller displays. HDR support covers HDR10 and HLG, which addresses the majority of streaming platform content, but the absence of Dolby Vision is a specification gap relative to competing TVs in this screen class. The smart platform is LG's webOS, which has earned a reputation for responsive navigation and a well-organized app ecosystem, with both Netflix and YouTube supporting 4K HDR playback natively.

The standout differentiator for connected households is the dual voice assistant integration — Alexa and Google Assistant coexist on this platform alongside LG ThinQ, making it compatible with either major smart home ecosystem without requiring a separate device. AirPlay 2 adds native Apple device casting, covering the three major ecosystems in a single TV. Bluetooth 4.2 enables LG Sound Sync pairing with compatible LG soundbars, which is worth considering given that built-in audio on a 75" panel at this price tier rarely matches the visual experience. This renewed unit represents a practical path to a large-screen 4K smart TV with a full smart platform at below-launch pricing — best suited for buyers who prioritize screen size and ecosystem connectivity over cutting-edge panel technology.

Pros & Cons

👍 Pros

75-inch panel delivers an immersive screen size that meaningfully benefits from 4K resolution at typical living room viewing distances
Native integration of both Alexa and Google Assistant eliminates the need for external smart speakers to voice-control the TV
AirPlay 2 built into webOS allows direct iPhone and Mac screen mirroring without additional hardware
webOS platform provides a well-regarded, snappy smart TV interface with major streaming apps pre-installed
Bluetooth 4.2 supports LG Sound Sync for seamless pairing with compatible LG soundbars without ARC configuration

👎 Cons

No Dolby Vision support — HDR is limited to HDR10 and HLG, which affects compatibility with some premium streaming libraries
As a renewed unit, panel uniformity and backlight condition cannot be guaranteed — 75-inch panels are particularly susceptible to handling damage during shipping
This is a 2019-generation panel; the VA or IPS panel technology and local dimming implementation trail current 2023+ OLED and QLED alternatives
Quad Core processor handles upscaling adequately but is not the same generation as LG's later α9 or α7 chip lineups, which affects AI processing quality
Built-in speakers on large flat panels at this price tier typically require a soundbar to deliver audio that matches the screen's visual presence

Frequently Asked Questions

Does this TV work with both Amazon Alexa and Google Assistant at the same time?

Yes. The 75UM7570 was one of the first LG TVs to integrate both Google Assistant and Amazon Alexa natively alongside LG's own ThinQ AI. You can use either voice assistant depending on preference — helpful if your home already has a mix of Amazon Echo and Google Home devices.

What does "Renewed" mean for a TV this size, and what condition should I expect?

Renewed TVs have been inspected and tested for functionality. At 75 inches, cosmetic handling is harder to guarantee than with a smaller unit — inspect the screen carefully on arrival for dead pixels, backlight uniformity issues, or panel pressure marks. The panel itself is the primary risk with renewed large-format TVs; the electronics are generally straightforward to test.

Does AirPlay 2 work reliably for casting from iPhone or Mac?

AirPlay 2 is built into the webOS platform on this TV, so it does not require an Apple TV or additional hardware. In practice, AirPlay 2 on LG's webOS is reported as reliable for video and audio mirroring from iOS and macOS devices on the same Wi-Fi network, though responsiveness can vary with network congestion.

What HDR formats does this TV support?

The 75UM7570 supports HDR10 and HLG (Hybrid Log-Gamma). It does not support Dolby Vision or HDR10+. For most streaming services, HDR10 content will display correctly, but users invested in a Dolby Vision library should note the limitation.

Is the Quad Core processor in this TV related to the display's 4K upscaling performance?

Directly, yes. The Quad Core processor handles 4K upscaling of lower-resolution content in real time, as well as noise reduction and motion smoothing. On a 75" panel, the quality of upscaling from 1080p or 720p sources is visible at normal viewing distances, so the processor's contribution to image quality is meaningful in everyday use.
