LG C4 65" vs Sony X77L 55"
LG's C4 represents flagship OLED technology with a stunning 1300-nit OLED evo display, Dolby Vision support, and exceptional 1ms gaming performance via 120Hz refresh rate and ALLM. Sony's X77L offers solid LED-based 4K performance at a significantly lower price point, though its 400-nit brightness and 60Hz maximum refresh rate limit competitive gaming and bright-room viewing. Audio capabilities heavily favor LG with 60W, 2.2ch Dolby Atmos versus Sony's modest 20W 2.0ch setup. Processing differs substantially—LG's α9 Gen 7 AI Processor outperforms Sony's X1 chip for upscaling and noise reduction. For movie enthusiasts and gamers willing to invest, the C4's superior contrast, color accuracy, and gaming features justify the premium. Budget-conscious buyers accepting compromises on brightness and refresh rates gain excellent value with the X77L. LG C4 65" is the superior choice for performance-focused buyers.
