Sony BRAVIA XR A90K 48" OLED TV vs Sony K55XR80 BRAVIA 8 55" 4K OLED Smart TV

Both are Sony 4K OLEDs with 120 Hz panels, HDMI 2.1, VRR and Google TV, so picture quality is close. The A90K is the 2022 48-inch set with the Cognitive Processor XR and a stand that sits low and wide; the BRAVIA 8 is the 2024 55-inch model with the newer XR Processor, Dolby Vision, Dolby Atmos, IMAX Enhanced and ATSC 3.0. Buy the BRAVIA 8 for a main living-room TV and the A90K if you need a smaller 48-inch OLED for a bedroom or desk. Owners rate the BRAVIA 8 well (4.4 from 601 ratings); the A90K is older but still a strong small OLED.

• Choose the Sony A90K if you want a 48-inch OLED and a smaller footprint matters more than the newest processing and tuner.
• Choose the Sony BRAVIA 8 if you want the larger 55-inch screen, Dolby Vision and Atmos, IMAX Enhanced and next-gen ATSC 3.0 tuning.
