LG OLED C5 Series 4K TV vs Sony 42" BRAVIA XR A90K 4K HDR OLED TV With Smart Google TV - XR42A90K

The LG C5 is the better pick for most people: a 55-inch panel, 144Hz refresh, four HDMI 2.1 ports and support for Dolby Vision, HDR10+ and HLG make it a stronger all-rounder for movies, sports and gaming. The Sony A90K is a 42-inch set with a 120Hz panel, Sony's Cognitive Processor XR, Acoustic Surface Audio+ and Google TV, and it suits small rooms and close-up viewing where a 55-inch screen would overwhelm the space. Reviewers consistently praise LG's OLED picture and gaming features, while Sony owners tend to cite build, sound and motion handling; both are well-regarded OLEDs, so the choice comes down to size and use.

• Choose the LG C5 if you want the larger 55-inch screen, 144Hz gaming, four HDMI 2.1 ports and Dolby Vision plus HDR10+ support.
• Choose the Sony A90K if you need a compact 42-inch OLED for a small room or desk setup and value Sony's processing, Acoustic Surface Audio+ and Google TV.
