- Model numbers and patterns

What is true of this model and changes how you fix it
- Panel — QLED with full-array local dimmingVIZIO's 2023 flagship LCD: a QLED with full-array local dimming and high brightness. A backlight, so blooming/halo around bright objects and raised dark-room blacks are normal LCD behavior, not a fault; local dimming set higher reduces the halos.
- Smart platform — SmartCastSmartCast with Chromecast built-in, AirPlay 2 and WatchFree+. Update at Settings › System › Check for Updates. Not Roku/Google TV/Tizen.
- Gaming / HDMIFour HDMI 2.1 ports with 120 Hz, VRR and FreeSync Premium Pro — the most HDMI 2.1 ports of any VIZIO here. Supports Dolby Vision and HDR10+. Enable Game Mode for the input.
- Size and weightThe 65-inch is 56.92 x 32.67 x 2.94 in and weighs 41.01 lb without the stand.
- Where the Quantum Pro sitsThe Quantum Pro is VIZIO's brighter, higher-end Quantum set, with more dimming zones and a faster panel. It still runs SmartCast, and the Picture menu's Calibrated Dark and Vibrant modes show the range of its brightness.
- GamingThe set supports 4K at 120 hertz, variable refresh and auto low-latency mode on its HDMI 2.1 ports. A console not reaching 120 hertz should be set to its enhanced HDMI output and connected to one of the ports that support it.
- Heat and ventilationA bright backlight runs warm, so leave the back of the TV clear and avoid placing it in a closed cabinet. A TV that shuts off by itself after a long time in a hot room may be protecting itself, and moving it to a cooler place stops that.
- Also coveredV-Series 4K TV, ports and refresh (from Tom's Guide and TechHive): Three HDMI ports on the right side, one of them with ARC, running 4K at 60 Hz. The V-Series has no 4K 120 Hz mode, so a game console at 120 Hz falls back to 60.
- Also coveredV-Series 4K TV, sizes: From 43 to 75 inches, positioned as Vizio's entry-level 4K TV.
- Also coveredM-Series Quantum X TV, HDMI (from RTINGS and Reviewed): One HDMI 2.1 port and three HDMI 2.0, one of which has eARC. Because only one port has the bandwidth for 4K 120 Hz, owning both a PS5 and an Xbox Series X means swapping cables.
