LG G4 77" vs Sony X90L 65"
The Verdict
LG's G4 77" represents the pinnacle of OLED television technology with its Micro Lens Array display achieving exceptional 2100-nit peak brightness, superior contrast, and perfect 1ms input lag for gaming. Its 60-watt 4.2-channel Dolby Atmos system significantly outperforms Sony's modest 20-watt output. However, Sony's X90L 65" offers compelling value at roughly one-third the price, delivering respectable picture quality through Full Array LED with 1300-nit brightness and minimal 8ms input lag. The X90L's Cognitive Processor XR handles upscaling admirably, and Google TV provides a cleaner smart interface than webOS 24. Both support 120Hz gaming with VRR/ALLM, though the G4's substantially larger screen, superior brightness, and premium audio justify premium positioning for cinephiles and enthusiasts. For budget-conscious gamers prioritizing value, the X90L presents solid performance; the G4 is the clear choice for those demanding the best in image quality and immersion.
