Our Verdict
LG C1 OLED
LG A1 OLED
The LG A1 OLED and the LG C1 OLED deliver very similar picture quality but differ in the extra features available. The C1 is a better gaming TV, with four HDMI 2.1 ports, support for variable refresh rate technology (VRR), and a 120Hz refresh rate. For movie lovers, the C1 is also a slightly better choice, as it can remove judder from any source, and it has an optional Black Frame Insertion feature to help reduce persistence blur.
