LG B6E Series OLED 4K Smart TV vs Samsung S90D OLED 4K TV

Both are 55-inch 4K OLEDs with 120Hz panels, four HDMI ports and strong HDR, so picture quality is close. The LG B6E runs webOS with Google Gemini built in and adds Dolby Vision, G-Sync and FreeSync Premium, which suits movie watchers and console gamers. The Samsung S90D uses the NQ4 AI Gen2 processor, has a brighter, more aggressive HDR push with PANTONE-validated color, and its 2.1.2-channel 60W audio with Object Tracking Sound beats the LG's built-in sound. Owners rate the LG higher on average, but the Samsung has far more ratings behind it. Pick the LG for Dolby Vision content and gaming features; pick the Samsung for sound and a punchier HDR image.

• Choose the LG B6E if you watch a lot of Dolby Vision movies or game on a PC or console and want G-Sync, FreeSync Premium and a 0.1ms response time.
• Choose the Samsung S90D if you want stronger built-in sound and a brighter, more saturated HDR picture without adding a soundbar.
