LG OLED 42-inch TVs

What makes LG OLED 42-inch TVs special?

The 42-inch OLED was first introduced by LG in 2021 and quickly became popular for people who want a high-end picture without a very large screen. LG OLED 42-inch TVs use self-emissive pixels. Each pixel can turn off individually for true black, high contrast, and excellent HDR. That makes a 42-inch OLED ideal for living rooms, bedrooms, and dedicated gaming setups.
