Our Verdict
LG CX OLED
Samsung The Sero
The LG CX OLED is significantly better than the Samsung The Sero; however, they're very different TVs. The LG has an OLED panel that's better suited for dark rooms, while the Samsung has an IPS panel and is designed for watching content in portrait mode. The LG delivers much better picture quality, and it's better for gaming due to its faster response time, 120Hz refresh rate, and VRR support. However, the Samsung stutters less in lower frame content such as movies, and its IPS panel is immune to permanent burn-in.
