Samsung S84F 55" OLED 4K TV vs Samsung S85F OLED 4K Smart TV

Both are 55-inch 4K OLED TVs with 120 Hz panels, four HDMI ports and Tizen, so the picture fundamentals are close. The S84F adds Dolby Atmos with top-firing speakers and HDR10+, while the S85F adds an anti-glare coating and lists Wi-Fi 5 and Bluetooth explicitly. Buy the S85F if your room has windows or lamps that reflect on the screen; buy the S84F if built-in sound and HDR10+ matter more. Owners of Samsung OLEDs praise the contrast and slim build but note OLED brightness is lower than high-end LCD in bright rooms.

• Choose the Samsung S84F if you want stronger built-in audio with Dolby Atmos and top-firing speakers, plus HDR10+ support, and you can control glare with curtains or placement.
• Choose the Samsung S85F if your room is bright or has lamps facing the screen and you want the anti-glare coating, and you mostly use a soundbar anyway.
