LG OLED C3 55-inch TV vs Samsung S85F OLED 4K Smart TV

Both are 55-inch 4K OLEDs at 120 Hz with four HDMI inputs, so the picture fundamentals are close. The LG C3 is the safer pick for most people: it has a mature webOS platform, Dolby Vision, and a long track record with owners and reviewers. The Samsung S85F runs Tizen with Bixby built in and adds Dolby Atmos sound processing, but it lacks Dolby Vision and is a newer, less proven model. Buy the LG for movies and mixed use, and the Samsung if you want Tizen and Atmos in one set.

• Choose the LG C3 if you watch Dolby Vision movies, want the proven webOS app library and Magic Remote, or game on a set with a 0.1 ms response rate.
• Choose the Samsung S85F if you prefer the Tizen interface, want Bixby voice built in, or care about Dolby Atmos sound processing.
