Our take on the Pioneer 50" R851 Series 4K UHD HDR LCD Roku TV Smart TV (PN50-R851-26C) - 2025

The Pioneer R851 is a 50-inch 4K LCD TV running Roku TV, with HDR support, a direct-lit backlight and a 60Hz panel. It covers the basics well: three HDMI ports, two USB media ports and a standard 400x300 VESA mount. It suits budget buyers and secondary rooms where a simple smart interface matters more than deep blacks or wide viewing angles. Against rivals at this tier, Roku TV is the main draw; picture quality trails sets with full-array local dimming or 120Hz panels.

Pros
  • Roku TV interface is simple and well stocked with apps
  • Three HDMI inputs cover a console, soundbar and streamer
  • HDR support adds some highlight range on streaming content
  • 400x300 VESA pattern fits common wall mounts
  • Two USB ports for media playback and accessories
Cons
  • 60Hz panel limits motion smoothness for sports and gaming
  • Direct-lit backlight without local dimming gives uneven blacks
  • 8W bottom speakers are thin; a soundbar is worth adding
  • Narrow viewing angles on this class of LCD panel

Questions and answers

Is the Pioneer R851 good for gaming?
It accepts 4K at 60Hz, which is fine for casual console play. It lacks 120Hz and variable refresh rate, so fast competitive games will look less smooth than on gaming-focused sets.
Does it have local dimming?
No. The backlight is direct-lit across the whole panel without zones, so dark scenes look grayish compared with sets that dim sections of the screen.
What is in the box?
The TV, a stand, a Roku remote and power cable. A wall bracket is not included; use a 400x300 VESA mount if you hang it.
Do I need a soundbar?
The built-in 8W bottom speakers are adequate for news and sitcoms. For movies or music, a soundbar over HDMI is a clear upgrade.
Can I use it without cable?
Yes. Roku TV streams over Wi-Fi and has the major apps built in. An antenna works too if you want free local channels.
Is 50 inches right for my room?
It suits viewing distances of roughly 6 to 9 feet. In a large, bright living room, a bigger set will feel more immersive.
