TCL QM8 65" vs Vizio P-Series Quantum 65"
The Verdict
Both TVs share the same $999 price point at 65 inches, but they excel in different areas. The TCL QM8 dominates with its Mini-LED QLED panel delivering exceptional brightness at 5000 nits compared to the Vizio's 1200 nits, making it superior for bright rooms and HDR content. TCL's display also supports Dolby Vision IQ alongside HDR10+ and offers superior contrast through full-array local dimming with mini-LED backlighting. The TCL edges out gaming performance with 6ms input lag versus Vizio's 8ms, and both support 120Hz with VRR and ALLM. Audio quality favors TCL significantly: its 50-watt 2.1-channel system with Dolby Atmos substantially outpaces Vizio's bare 20-watt 2.0-channel setup. The Vizio counters with a sleeker 3-inch profile (versus TCL's 12.8 inches with stand) and lighter weight at 44.7 lbs, appealing to wall-mount enthusiasts. Software is comparable with both offering Google Assistant, though Vizio adds Alexa support. The TCL QM8 is the clearer choice for picture quality and immersive audio, particularly if you value brightness and contrast. Select the Vizio only if wall mounting with minimal protrusion is your primary concern.
