Our take on the Pioneer 70-inch Class LED 4K UHD Smart Roku TV

The Pioneer PN70-R851-26U is a 70-inch 4K LCD TV with a direct-lit LED backlight and HDR10 support, running the Roku TV smart platform. Its appeal is simplicity: Roku's home screen, the Roku mobile app and 500+ free live channels, with no voice assistant built in. It is a 60 Hz panel with no motion enhancement, so it suits everyday streaming, sports and broadcast TV rather than high-frame-rate gaming or cinephile dark-room viewing. Against rivals, it competes on screen size and the Roku interface rather than on brightness, local dimming or 120 Hz motion.
