Roku Select Series 4K QLED TV vs TCL Q3K Series 1080p QLED Smart TV

These are different classes of TV, not close rivals. The Roku Select Series is a 75-inch 4K QLED with four HDMI ports, HDR10+, Ethernet, and the Roku OS; the TCL Q3K is a smaller 1080p QLED set on Google TV with two HDMI ports and no VESA mounting. Buy the Roku for a main room where size and 4K detail matter. Buy the TCL for a bedroom, kitchen, or secondary room where a smaller screen is the point. Owners rate the Roku higher, and its spec sheet is stronger across the board.

• Choose the Roku Select Series if you want a big-screen 4K QLED for a main room, with enough HDMI inputs for a console, soundbar, and streaming stick.
• Choose the TCL Q3K if you need a compact secondary TV and value Google TV's app organization over resolution and input count.
