Design & Build Quality
The LG 65UN8500PUI features a slim modern design with narrow bezels that maximize screen real estate. The central stand gives it a stable footprint and a premium look suitable for living rooms and entertainment spaces.
Although not as ultra-thin as LG’s OLED models, build quality feels sturdy and well-constructed for its class.
Picture Quality & Display Performance
4K UHD Resolution
With four times the resolution of Full HD, the 65-inch 4K panel delivers sharp details and immersive visuals — especially noticeable when streaming high-quality 4K content or playing modern video games.
IPS Panel Advantages
The IPS display provides wide viewing angles, making it ideal for larger rooms where viewers may be seated off-center. Colors remain consistent even from the side.
However, like most IPS panels, contrast levels are not as deep as VA panels or OLED screens, meaning blacks may appear slightly gray in dark rooms.
HDR Support
The TV supports HDR10 and HLG formats, improving brightness and dynamic range when watching compatible content. While it doesn’t reach premium HDR brightness levels, it still enhances highlights and color vibrancy compared to standard dynamic range.
Gaming Performance
One of the standout features of the LG 65UN8500PUI is its gaming capability for a 2020 mid-range TV.
- Native 120Hz panel for smoother motion
- Low input lag in Game Mode
- HDMI 2.1 support for next-gen consoles (on selected ports)
- Variable Refresh Rate (VRR) support
For PlayStation 5 and Xbox Series X users, HDMI 2.1 enables higher refresh rates and smoother gameplay. While it’s not positioned as a high-end gaming TV, it performs well for casual and competitive gaming.
Smart TV Platform – webOS
LG’s webOS platform remains one of the easiest smart interfaces to navigate. The launcher bar at the bottom allows quick access to apps, inputs, and settings.
Popular streaming apps available include:
- Netflix
- Amazon Prime Video
- Disney+
- YouTube
- Hulu
The interface is responsive and user-friendly, even several years after release.
Alexa Built-in & Voice Control
The LG 65UN8500PUI includes Alexa built directly into the TV. This allows you to:
- Search for content using voice commands
- Control volume and inputs
- Manage compatible smart home devices
It also supports Google Assistant, giving users flexibility in voice ecosystem preference.
Audio Performance
The built-in speakers provide clear dialogue and balanced sound for everyday TV viewing. However, bass response is limited — typical for slim TVs.
For a more cinematic experience, pairing with a soundbar (especially one supporting Dolby Atmos) will significantly improve immersion.
Connectivity & Ports
- 4× HDMI ports (including HDMI 2.1 support)
- USB ports for media playback
- Ethernet port
- Wi-Fi & Bluetooth
- Optical audio output
Connectivity is robust and suitable for multiple devices such as consoles, streaming boxes, and sound systems.
