LG OLED A2 55" vs Sony X90L 65"
The Verdict
LG's A2 OLED delivers exceptional contrast and perfect blacks at a compelling $899 price point, ideal for movie enthusiasts on a budget. Sony's X90L commands $200 more but justifies it with a larger 65-inch screen, significantly brighter 1300-nit peak brightness (versus 500 nits), native 120Hz refresh rate with VRR support, and superior gaming features like 8ms input lag versus 14ms. Picture quality favors the OLED in dark rooms due to perfect blacks, yet the X90L excels in bright environments and delivers smoother gaming performance. Both offer Dolby Vision and identical audio specs at 20W. The X90L's Cognitive Processor XR and Full Array LED backlighting provide more dynamic highlights and gaming responsiveness. For cinephiles prioritizing contrast and minimalist design, the A2 is excellent. Gamers and those in brightly-lit rooms seeking larger screens should choose the X90L's superior brightness and 120Hz capability.
