Roku Pro Series 55-Inch 4K TV vs LG B6 48" OLED TV

The LG B6 is the better picture for a dark room: per-pixel OLED gives true blacks and no blooming, and its gaming features (0.1ms response, G-Sync, FreeSync Premium, VRR) are stronger. The Roku Pro Series is the bigger screen at 55 inches and a Mini-LED QLED that holds up better in a bright room, with Roku OS and Wi-Fi 6 built in. Reviewers and owners rate the LG around 4.1 out of 5, generally praising the contrast and flagging peak brightness limits; the Roku's Mini-LED dimming is well received but its panel is LED, not OLED.

• Choose the Roku Pro Series if you want the larger 55-inch screen, a bright Mini-LED picture for a sunny room, and Roku OS with Wi-Fi 6 without adding a streaming box.
• Choose the LG B6 if you watch in a dark room, care most about black levels and contrast, and want the strongest gaming features in this pair.
