Overview

The LG 50UQ7070Z is the kind of TV that makes the most sense when you're upgrading from a five-year-old 1080p set and want 4K, a smart OS, and voice control without paying full retail. The renewed designation means you're trading cosmetic perfection for a meaningful price drop — and everything that matters, the processor, the streaming platform, and the HDR capability, is exactly the same hardware you'd get in a new box. It targets cord-cutters who want their streaming services front-and-center and don't want to fiddle with external sticks or boxes.

At 50 inches, the panel hits a sweet spot for mid-sized rooms. The α5 Gen5 AI Processor does real work upscaling cable and streaming content, and Active HDR (HDR10 + HLG) with Dynamic Tone Mapping keeps highlights from blowing out. WebOS is snappy, the voice control integration with both Alexa and Google Assistant is seamless, and the Game Optimizer genuinely simplifies what used to require navigating buried picture settings. The single HDMI port is the hardware constraint that demands honest acknowledgment — plan accordingly if you're connecting multiple devices. But as a streamlined, all-in-one smart TV for everyday use, it delivers.

Pros & Cons

👍 Pros

  • The α5 Gen5 AI processor does a convincing job upscaling HD content to near-4K sharpness on a 50-inch panel.
  • WebOS is one of the cleaner smart TV interfaces — fast to navigate and rarely requires digging through menus.
  • Active HDR with Dynamic Tone Mapping gives noticeably better highlight/shadow balance compared to basic HDR10-only sets.
  • Bluetooth Surround Ready means you can pair LG soundbars wirelessly without running cables.
  • Renewed pricing makes this a legitimate value play for a living room upgrade.

👎 Cons

  • Only one HDMI port is a real constraint if your setup includes a console, soundbar, and external streamer.
  • 60Hz native refresh rate means fast-motion sports or action games won't have the buttery smoothness of 120Hz panels.
  • As a renewed unit, cosmetic wear and lack of original packaging are expected trade-offs.
  • No mention of local dimming, so deep black performance in dark rooms lags behind OLED or full-array LED sets.

Frequently Asked Questions

For most buyers, renewed makes a lot of sense here. LG's WebOS platform and α5 Gen5 processor are proven, and a 50-inch 4K screen at a reduced price means you're getting flagship-tier smarts without the flagship price tag. Just verify the seller's return window.
No stick needed. Netflix, Disney+, Apple TV, Prime Video, Hulu, Peacock, and YouTube TV are all baked into WebOS, plus 300+ free LG channels. It's a solid all-in-one streaming hub out of the box.
Yes, both are supported natively. You can use either assistant to switch inputs, adjust volume, launch apps, and control playback — without a separate smart speaker bridge.
The Game Optimizer mode is a genuine upgrade from older panels. You get dedicated tuning for FPS, RPG, and RTS genres, plus black/white stabilization for better shadow detail — all manageable from a single menu.
It can be, depending on your setup. If you're running a console, soundbar, and streaming device simultaneously, you'll want an HDMI switch. This is the most notable hardware limitation on an otherwise well-featured panel.
