Sony X77L series vs LG UR9000 series: Which One Should You Buy?
The Sony X77L and LG UR9000 are entry-level 2023 4K televisions with 60 Hz panels, HDR10 and HLG support, three HDMI inputs, eARC and Auto Low Latency Mode. Neither supports VRR, 4K at 120 Hz, Dolby Vision or zone-based local dimming. Sony distinguishes itself with Direct LED backlighting, Google TV, Chromecast built-in and PlayStation 5 integration. LG counters with webOS 23, the Magic Remote, FILMMAKER MODE, Game Optimizer, HGiG and broader smart-home integration. The better choice depends primarily on smart-platform preference and feature priorities rather than a proven picture-quality winner.

UR9000 Series 4K HDR Smart LED UHD TV
A 60 Hz 4K LCD television featuring webOS 23, the Magic Remote, FILMMAKER MODE, Game Optimizer and broad smart-home integration.
Key technology
α5 AI Processor 4K Gen6LG picture and sound processor that performs 4K upscaling and automated image and audio adjustments.
HDR10 ProLG processing for HDR10 content; the supported incoming HDR formats remain HDR10 and HLG.
Dynamic Tone MappingAdjusts HDR tone mapping based on the content being displayed.
Dimming ProLG picture processing that adjusts image brightness and contrast; it is not a verified zone-based full-array local-dimming system.
Game Optimizer and Game DashboardCentralizes gaming picture and latency settings and provides quick access to them while playing.
AI Sound ProProcesses the two-channel speaker output to create a virtual 5.1.2-style sound field.
FILMMAKER MODEA picture preset designed to reduce unnecessary processing and preserve the creative presentation of compatible film and television content.
ThinQLG's connected-device and smart-home control platform integrated into webOS.
Buyer advantages
- The Magic Remote provides pointer-style navigation that can make webOS menus and on-screen keyboards easier to use.
- FILMMAKER MODE and two ISF Expert presets give movie viewers clearly identified options intended to reduce unnecessary processing or accommodate different room lighting.
- Game Optimizer and Game Dashboard place gaming picture and latency controls in one interface for quicker adjustments while playing.
- HGiG support provides an HDR gaming option designed to work with compatible console tone-mapping procedures.
- ThinQ, Alexa, Google ecosystem compatibility, Matter and Apple AirPlay 2 provide broad smart-home and mobile-device integration.
- The 65-inch model supports a narrow 16.7-inch hybrid stand position in addition to its normal position, making it more adaptable to smaller furniture.
Things to consider
- The native panel and maximum verified 4K input rate are limited to 60 Hz, so the television cannot display 4K 120 Hz games.
- VRR is not supported, which can leave visible tearing when a game's frame rate and the display refresh rate do not remain synchronized.
- Dimming Pro is picture processing rather than a verified zone-based local-dimming backlight, limiting independent control of bright and dark image regions.
- The Edge LED backlight does not provide independently controlled zones for improving HDR contrast.
- HDR support is limited to HDR10 and HLG, with no Dolby Vision or HDR10+ compatibility.
- Only three HDMI inputs are available, and the television does not list Dolby Atmos or DTS support.

Which one should you buy?
The Sony X77L is the stronger fit for shoppers who want Google TV, built-in Chromecast, PlayStation 5 automation or a fully documented 85-inch television. Its Direct LED backlight is also a meaningful design difference from LG's Edge LED system, although that alone does not establish superior measured picture quality. The LG UR9000 is better suited to shoppers who prefer webOS, the Magic Remote, FILMMAKER MODE, Game Optimizer and wider smart-home integration. Both models remain basic 60 Hz televisions with three HDMI inputs, no VRR, no 4K 120 Hz support, no Dolby Vision and no zone-based local dimming. Buy according to platform, controls, gaming tools and available size rather than expecting premium HDR or competitive high-frame-rate gaming.
