Best forYou want a 40 in tv with roku's app platform built in, no streaming stick needed

Makes sense as a compact 40 in set for a room where 4K isn't a priority and built-in Roku apps are the main draw over an external streaming stick.

Overview

The Roku 40R3D5 is a 40 in LED TV with 1080p Full HD resolution, a 60Hz refresh rate and Roku's smart platform built in, connecting over Wi-Fi or Bluetooth.

The smart platform runs on the TV itself here, since Roku is listed as a built-in feature rather than an accessory box plugged into an HDMI port. Resolution stays at 1080p and refresh rate at a standard 60Hz, so this sits below the 4K sets common at larger screen sizes, which fits its smaller 40 in class.
