Pros & Cons
👍 Pros
- Pixel-level dimming with 8.3 million self-emitting pixels produces perfect black levels no LED TV can match
- 4K Cinema HDR supports Dolby Vision, HDR10, and HLG — covers virtually every HDR format in current use
- Dolby Atmos processing adds genuine depth to audio on supported content
- α9 Intelligent Processor delivers noticeably sharper upscaling of non-4K content compared to midrange panels
- Four HDMI inputs plus three USB ports give plenty of connectivity for a full home theater setup
👎 Cons
- 2018 model — HDMI 2.1 is not supported, so 4K/120Hz gaming from current-gen consoles is not available on this TV
- No eARC support limits high-bandwidth audio passthrough to a soundbar or receiver
- OLED panels are inherently more susceptible to burn-in than LED under heavy static-image use
- Peak brightness, while improved over prior OLED generations, still trails the best LED/mini-LED TVs in very bright rooms
- As a discontinued model, firmware updates and platform support from LG may be limited going forward
Frequently Asked Questions
What makes OLED picture quality different from a high-end LED TV in everyday use?
The difference is immediately visible in dark scenes. Because each of the 8.3 million pixels on the E8 generates its own light and can switch off completely, black areas of the screen are genuinely black — not dark gray like LED panels. That contrast difference makes the whole picture look more cinematic and three-dimensional in normal living room conditions.
Does this TV support Dolby Vision and Dolby Atmos?
Yes to both. Dolby Vision handles HDR with scene-by-scene tone mapping for compatible streaming content on Netflix, Apple TV+, and Disney+. Dolby Atmos delivers the immersive audio layer when your source supports it — though the TV's built-in speakers will benefit from Dolby Atmos processing, a soundbar or AV receiver extracts the full effect.
How does Google Assistant integration actually work on this TV?
Google Assistant is built into the webOS platform and accessible via the LG Magic Remote. You can use it to search for content, control smart home devices, answer questions, and adjust TV settings — all by voice without reaching for your phone. It also works alongside Amazon Alexa devices if you're already in that ecosystem.
Is burn-in a real concern with this OLED model?
It's a known OLED characteristic, not a defect. Static elements — channel logos, news tickers, game HUDs — displayed for many consecutive hours over a long period can cause image retention. LG includes screen-care features like pixel refreshers and screensavers. For typical mixed-use viewing, burn-in is rarely an issue in practice, but it's worth knowing if you plan to use it as a dedicated monitor or gaming display with static overlays for many hours daily.
How many HDMI ports does this TV have, and does it support ARC?
The E8 has four HDMI inputs, and one supports Audio Return Channel (ARC), so you can run audio out to a soundbar or receiver over the same HDMI cable your streaming device uses for video. No eARC on this model — that came in later generations.
