Why This Deal Is Worth It
At only $178, the ONN 50″ Roku TV offers unmatched size-for-price value. With native Roku streaming built in, it eliminates the need for external devices and stands out in a class where most competitors charge at least $250–300 for similar specs. While the display lacks brightness and polish, it’s serviceable for secondary use—ideal for kitchens, bedrooms, or casual viewing in dim to moderate lighting.
Who Should Grab This

- Buyers wanting built-in Roku streaming without needing separate boxes
- Users are placing a TV in secondary spaces like kitchens, basements, guest rooms, or garages
- First-time smart TV buyers or casual streamers who prioritize simplicity over image fidelity
Lab-Tested Performance That Backs It Up
- Color Gamut: ~96.7% sRGB, which is low for 4K—colors look muted vs. higher-end TVs²
- Brightness & Contrast: Notably dim with poor black levels compared to budget TCL models (blacks appear murky in dark scenes)²
- Input Lag: ~32 ms in Game mode—acceptable for casual play, but noticeable delay for fast-paced gaming²
- Viewing Angle Behavior: Significant color and brightness loss past ~20° off-axis—ideally viewed head-on²
- Smart Platform: Roku OS provides consistent performance even on budget hardware; the remote and UI remain responsive over time¹
- Long-Term Reliability: Reddit feedback varies—some report TVs failing after 1–2 years; others say value outweighs lifespan concerns¹³
