LG OLED evo C4 42-Inch 4K Smart TV vs Samsung S90F 42" OLED TV

Both are 42-inch 4K OLEDs at 120Hz, so the picture is close. The LG C4 runs webOS with four HDMI 2.1 ports, Dolby Vision and G-Sync, and owners rate it highly for gaming and film. The Samsung S90F is a 2025 set with HDR10+ instead of Dolby Vision, Tizen, and a 144Hz motion mode. Pick the LG for Dolby Vision movies and proven G-Sync support; pick the Samsung for HDR10+ content, Tizen, and the newer model year.

• Choose the LG C4 if you watch Dolby Vision movies, game on a PC with G-Sync, or want the most established 42-inch OLED with a strong owner record.
• Choose the Samsung S90F if you want a 2025 set, prefer Tizen and its voice assistants, or watch a lot of HDR10+ content.
