Our take on the VIZIO P75QXH1 P-Series Quantum X 4K Hdr Smart Tv
The Vizio P75QXH1 is a 75-inch 4K LCD TV in Vizio's P-Series Quantum X line, the step above the standard P-Series. It uses a quantum-dot panel with full-array local dimming and high brightness for HDR, and runs Vizio's SmartCast platform with built-in streaming apps and casting. It suits buyers who want a big, bright HDR picture for movies and sports and are willing to tune the picture themselves. Against rivals like the TCL QM8 and Hisense U8, it competes on brightness and dimming zones but gives up some polish in processing and smart features.
- Quantum-dot panel with full-array local dimming
- High brightness for HDR highlights
- Large 75-inch screen
- SmartCast apps plus Chromecast and AirPlay casting
- Four HDMI inputs, including HDMI 2.1 features for consoles

Questions and answers
- Is the Vizio P75QXH1 good for gaming?
- Yes. It has low input lag in game mode and HDMI inputs that support 4K at 120Hz for current consoles and PCs. Check that the input is set to the right mode for full bandwidth.
- How does it compare with the standard Vizio P-Series?
- The Quantum X adds a quantum-dot panel, more dimming zones and higher brightness. The standard P-Series is dimmer and has fewer zones, so the Quantum X is the better pick for HDR.
- Does it support Dolby Vision and HDR10?
- Yes. It handles Dolby Vision, HDR10 and HLG, so most streaming HDR content plays in its best format.
- What is in the box?
- The TV, its stand feet, a remote and the power cable. A wall mount and HDMI cables are not included.
- Does it have AirPlay and Chromecast?
- Yes. SmartCast supports Apple AirPlay 2 and Chromecast built-in, so you can cast from phones and laptops.
- Is the 75-inch screen right for my room?
- A 75-inch set suits viewing distances of roughly 8 to 12 feet. Measure your wall and seating before buying, since the panel is wide and needs a sturdy stand or mount.
