Our Verdict

Sony 42 A90K OLED

LG C4 42 OLED

The Sony 42 A90K OLED and the LG 42 C4 OLED are both 42-inch OLED displays. The C4 is the better option for most people, as it has a slightly higher refresh rate and gets brighter. However, the Sony is still a good option if you can find it for less and don't mind the reduced brightness.
