The LG C2 emerges as the clear winner in this head-to-head battle against the Vizio P65QX-H1. While Vizio's flagship Quantum X offers impressive brightness and a tempting price tag, LG's OLED technology delivers unmatched picture quality, near-instant response times, and future-proof gaming features that make the C2 the superior choice for most buyers in 2023.

Key Specifications

Picture Quality: OLED's Perfect Blacks Crush LCD Limitations

Let's cut straight to the chase: the LG C2's self-emissive OLED panel produces blacks so deep they make the Vizio P65QX-H1 look like it's wearing a cheap veil. While Vizio throws 384 local dimming zones at the problem, haloing and blooming remain visible during demanding scenes like space battles or night shots. The C2 simply turns pixels completely off, delivering infinite contrast that makes every movie feel cinematic.

Vizio fights back with claimed brightness levels that can hit nearly 2000 nits in highlights, giving HDR content serious punch in bright rooms. The P65QX-H1 is no slouch here. However, the LG C2 maintains excellent color volume and accuracy even at lower peak brightness thanks to its advanced Evo panel. Skin tones look more natural, and color gradients are smoother on the LG. If you're watching in a completely light-controlled theater room, the C2 is untouchable. In a living room with windows, the Vizio holds its own better during daytime sports.

Gaming Performance: LG C2 is Built for Next-Gen Consoles

Gamers, stop reading reviews and just buy the LG C2. The difference isn't close. With four HDMI 2.1 ports running at full 48Gbps bandwidth, the C2 supports 4K@120Hz with VRR on every port. Input lag measures an astonishing 5ms in game mode. The Vizio isn't bad with its own 4x HDMI 2.1 ports and low lag, but it lacks the refinement, G-Sync certification, and cloud gaming integration that make the C2 feel like it was designed by gamers for gamers.

The LG also includes an exclusive Game Optimizer dashboard that lets you tweak settings for different genres instantly. Whether you're playing fast-paced FPS titles on PS5 or immersive RPGs on Xbox Series X, the C2 simply feels more responsive. Vizio's 120Hz panel is decent, but the C2 can effectively reach 240Hz in certain game modes, giving competitive players a measurable edge.

Smart Features and Sound: LG's webOS Dominates Daily Use

Using these TVs every day reveals another gap. LG's webOS 22 is lightning fast, beautifully designed, and packed with apps. Voice control through the Magic Remote feels intuitive and actually works. Vizio's SmartCast has improved but still feels clunky by comparison, with slower navigation and occasional bugs that remind you this platform was an afterthought.

Neither TV has particularly impressive built-in audio, but the LG C2 again pulls ahead with better processing and support for Dolby Atmos that creates a more convincing soundstage. Both support eARC for external soundbars, but if you're serious about audio, pair either with a dedicated system. The C2's AI Sound Pro feature does a better job of upmixing content to feel more immersive.

Design and Build: Vizio is Lighter but LG Feels Premium

The Vizio P65QX-H1 wins on pure physical practicality. At just 54.9 pounds, it's dramatically lighter than the LG's 91.7 pounds, making wall mounting and setup easier for average consumers. Its design is clean if unremarkable. The LG C2, however, features an impossibly thin 1.8mm bezel that makes the screen appear to float. The Gallery Design stand or wall mount options make it look like modern art. Yes, it's heavier, but that weight comes from the premium materials and heat dissipation system required for the OLED panel.

Who Should Buy Which?

Buy the LG C2 if:

• You prioritize absolute best picture quality and perfect blacks
• You're a serious gamer with PS5, Xbox Series X, or high-end PC
• You watch mostly in controlled lighting environments
• You want the most future-proof TV with best smart features
• You're willing to pay for premium performance

Buy the Vizio P65QX-H1 if:

• You're on a tighter budget and want maximum brightness
• Your room has lots of ambient light
• You mainly watch sports and bright HDR content
• Weight and easier installation matter to you
• You're okay with some compromises in black levels

Final Verdict

The LG C2 is the superior television and our undisputed winner. Here's why:

• Infinite contrast and perfect blacks that LCD technology simply cannot match
• Best-in-class gaming features with ultra-low input lag and full HDMI 2.1 implementation
• Superior smart platform and remote control experience
• More accurate colors and better motion handling for movies
• Future-proof design that will still impress years from now

While the Vizio P65QX-H1 offers compelling brightness and a much lower entry price on paper, it ultimately feels like last-generation technology next to the LG C2. The gap in overall performance, especially in dark room viewing and gaming, is simply too large to ignore. Unless your budget is extremely tight or your room is exceptionally bright, the LG C2 represents the smarter long-term investment and delivers the premium experience its higher price demands. At current street prices that have dropped significantly since launch, the value proposition strongly favors the LG C2 for discerning buyers.

Score: Vizio P65QX-H1 - 7.2/10 | LG C2 - 8.4/10
