Our take on the VIZIO Quantum 4K QLED HDR Smart TV 65" M65Q6-L4

The VIZIO Quantum M65Q6-L4 is a 65-inch 4K QLED smart TV running VIZIO OS. It supports Dolby Vision, HDR10+, HDR10 and HLG, so most HDR titles play in their native format, and WiFi 6 keeps streaming steady on a busy home network. Gaming gets Auto Low Latency Mode, a gaming menu and up to 120fps at 1080p, though not at 4K. Against rivals like the TCL Q6 and Hisense U6, it matches the QLED panel and full HDR format support but offers fewer local dimming zones and a weaker built-in speaker system, which is why the QuickFit soundbar mount matters. It suits budget-conscious buyers who want a big QLED screen for streaming and casual console play.
