Samsung S90F 48-inch OLED TV vs Roku Pro Series OLED TV

The Samsung S90F is the better TV for picture quality: it is a true OLED with per-pixel contrast, four HDMI ports, a 144 Hz-capable panel and strong gaming features. The Roku Pro Series gives you a much larger 65-inch screen and the simplest smart interface, but its listing describes a QLED panel, only two HDMI ports and weaker processing and sound. Buy the Samsung for a dark room, gaming or a smaller space; buy the Roku if screen size and an easy interface matter more than contrast.

• Choose the Samsung 48-inch S90F if you want OLED contrast, four HDMI inputs and gaming features like G-SYNC and FreeSync Premium Pro in a smaller room.
• Choose the Roku Pro Series if you want the biggest screen for the space and the fastest, simplest smart TV interface, and you can live with two HDMI ports.
