The LG C2 emerges as the clear winner in this head-to-head battle against the Sony A9G. With superior brightness, next-gen gaming features, and a more future-proof design, the LG C2 delivers a more compelling package for most buyers despite its higher weight.

Picture Quality: Brightness and Color Accuracy
The LG C2 takes a decisive victory in overall picture performance. Its Evo panel technology delivers noticeably higher peak brightness, hitting over 1000 nits in HDR content compared to the A9G's roughly 750 nits. This translates to more impactful highlights in movies like Blade Runner 2049 or The Batman, where specular highlights pop with greater intensity.
Sony's X1 Ultimate processor still produces excellent color accuracy and upscaling, often rendering skin tones and subtle gradients with a touch more refinement than the LG. However, the C2's α9 Gen 5 AI processor has closed that gap significantly and adds better motion handling for sports and fast action. Both TVs achieve perfect blacks thanks to their self-emissive OLED nature, but the LG simply looks more vibrant and alive in well-lit rooms.
Gaming Performance: Next-Gen Console Ready
If you're a gamer, the LG C2 is in a completely different league. With four full HDMI 2.1 ports, VRR, ALLM, and full G-Sync/FreeSync compatibility, it handles PS5, Xbox Series X, and high-refresh PC gaming without compromise. The 144Hz capability on certain sizes gives competitive gamers a real edge that the Sony A9G simply cannot match with its limited two HDMI 2.1 ports.
The Sony A9G offers solid gaming features for its era, including 120Hz support and low input lag, but it feels dated next to the C2. LG's Game Optimizer mode provides quick access to all settings, while Sony's approach feels more buried in menus. For anyone buying a TV in 2023 or later to pair with current-gen consoles or a gaming PC, the LG C2 is the only logical choice.
Design, Build Quality and Smart Features
The Sony A9G earns praise for its premium, minimalist design and significantly lighter weight at 54.7 lb compared to the LG C2's hefty 91.7 lb for the 65-inch model. Sony's TV feels easier to mount and handle during installation. Its picture-on-glass design looks stunning when mounted flush against a wall.
However, LG has the superior smart TV platform in 2023. webOS 22 is faster, more intuitive, and has better app support than Sony's aging Android TV interface. Voice control on the LG is more responsive, and the Magic Remote remains one of the best pointing devices in the industry. Sony's remote feels basic by comparison.
Neither manufacturer currently publishes official power consumption, battery capacity for remotes, or detailed warranty information beyond the standard one-year parts and labor, which is disappointing for premium products in this price range.
Who Should Buy Which?
Buy the LG C2 if:
- You want the best possible picture quality and brightness from an OLED
- Gaming is a priority (current or next-gen consoles/PC)
- You want the most future-proof TV with four HDMI 2.1 ports
- You're okay with a heavier panel and potentially higher price
Buy the Sony A9G if:
- You can find it at a significant discount
- Premium build quality and lighter weight matter more than peak brightness
- You prefer Sony's color science and processing for movies
- You're not heavily into high-frame-rate gaming
Final Verdict
The LG C2 is the superior television and our recommended pick for most consumers. It delivers a meaningfully better HDR experience, crushes the competition in gaming performance, and offers a more modern smart TV experience.
That said, the Sony A9G remains an excellent choice if you can find it substantially cheaper. Its lighter weight, refined design, and still-excellent picture quality make it attractive for movie enthusiasts who don't need bleeding-edge gaming features.
- Winner: LG C2 (8.0/10 vs 7.2/10)
- Brighter Evo panel delivers superior HDR impact
- Far better gaming features with 4x HDMI 2.1 ports
- More modern smart platform and processor
- Sony A9G wins on weight, price (when discounted), and certain design elements
- Neither brand publishes power consumption, remote battery capacity or extended warranty details
In the end, the LG C2 represents the evolution of OLED technology and stands as the better long-term investment for enthusiasts and gamers alike. Sony's A9G was a flagship in its day, but time and technological progress have favored LG's more advanced C2.
