LG B5 Series OLED 4K TV (2025) vs Samsung S90D OLED 4K Smart TV

Both are 48-inch OLEDs with 4K, 120Hz-plus panels and four HDMI 2.1 ports, so the picture and gaming basics are close. The Samsung S90D edges ahead on motion (up to 144Hz) and adds an anti-reflection screen, which helps in bright rooms. The LG B5 counters with Dolby Vision support, a proven webOS app platform and broad G-Sync and FreeSync coverage. Buy the Samsung for a brighter room and faster console gaming; buy the LG if you watch a lot of Dolby Vision movies and want the simpler, well-established smart system.

• Choose the LG B5 if you watch Dolby Vision movies and shows and want the familiar webOS app layout with long software support.
• Choose the Samsung S90D if your room has windows or lamps facing the screen and you game on a console that can push past 120Hz.
