Control all your Vizio TVs from one free app

Which Vizio TV you have — and how it takes commands

Vizio runs SmartCast across the whole range, from the entry D-series up through V, M, Quantum and the Mini-LED line. The bigger change is corporate: Walmart completed its acquisition of Vizio on 3 December 2024, taking the company private, and the newest models are Walmart and Sam’s Club exclusives.

Vizio TV model lines, the operating system each one runs, how it is reached over the network, whether pairing is required, and where the on-set button is.
Model line / series	TV operating system	How it is controlled over the network	Pairing	On-set button
D-series (entry)	SmartCast	HTTPS on ports 7345 and 9000, found by SSDP/DIAL	4-digit PIN on screen	Discrete buttons, rear bottom-left or bottom-right
V-series (budget 4K)	SmartCast	HTTPS on ports 7345 and 9000, found by SSDP/DIAL	4-digit PIN on screen	Discrete buttons, rear bottom-left or bottom-right
M-series and M-series Quantum X	SmartCast	HTTPS on ports 7345 and 9000, found by SSDP/DIAL	4-digit PIN on screen	Discrete buttons, rear bottom-left or bottom-right
Quantum / Quantum Pro and the Mini-LED line	SmartCast	HTTPS on ports 7345 and 9000, found by SSDP/DIAL	4-digit PIN on screen	Discrete buttons, rear corner
Pre-2015 models	Older Vizio software	Varies — predates current SmartCast	Varies	Front-left bezel or side edge

Vizio currently has two mobile apps in the stores — the long-running SmartCast Mobile and a newer, redesigned VIZIO Mobile. They coexist, which is why guides disagree about which one to install.

Reaching the menu with no remote

Plain buttons, not a joystick

Those rear buttons cover power, volume and input only. Reaching the network menu means a remote or a paired phone; if the set has never been online, Ethernet is the way through first-time setup.

Known Vizio failure mode

SmartCast loses the TV after a firmware update

What helps: Unplug the set at the wall for a full sixty seconds, then re-enter the Wi-Fi password rather than assuming it was kept. If the update was interrupted midway, clearing network settings and reconnecting is the documented next step.

FAQ

Frequently Asked Questions

Specific answers for Vizio TV users — including which Vizio lines run which system.

Can I control multiple Vizio TVs from one iPhone app?

Yes. Our free Vizio remote app discovers all Vizio SmartCast units on your Wi-Fi network simultaneously using SSDP/DIAL. Every TV appears in the device list — tap to switch between rooms instantly. Each connection uses HTTPS (port 7345/9000). Requires 4-digit PIN per TV on the first connection. No separate apps per TV, no subscription, and no limit on the number of TVs you can add.

How do I switch between multiple Vizio TVs in the remote app?

All Vizio SmartCast units on the same Wi-Fi network are discovered automatically via SSDP/DIAL and appear in the app's device selector. Tap any to switch control instantly — the app maintains connections to all Vizio SmartCast TVs simultaneously so switching is immediate with no re-pairing delay. The app prompts you to complete 4-digit PIN per TV on the very first connection only. Each subsequent connection is instant.

Is there a free Vizio remote app that works across all TVs in my home?

Our free Vizio remote app supports multi-room control with no additional cost. All Vizio SmartCast units on your home network are discovered simultaneously via SSDP/DIAL. You select individual TVs from the device list — no simultaneous broadcast mode, but switching between TVs is instant. Each TV connects via HTTPS (port 7345/9000). Requires 4-digit PIN per TV on first launch. No subscription, no account, no limit on TV count.

Does Vizio have its own remote app for this TV?

SmartCast Mobile, or VIZIO Mobile. Both are current. SmartCast Mobile is still being updated; VIZIO Mobile is the redesigned one, with voice control and WatchFree+ shortcuts. Check which your TV’s setup screen points you at before installing either.

Where is the button on the Vizio TV itself, and can it reach the settings menu?

Vizio uses a vertical stack of discrete buttons on the rear, in the bottom-left or bottom-right corner on sets from 2015 onward, with power at the top and volume and input below. There is nothing to tilt — these are simple buttons, which is why they cannot navigate a menu the way Samsung’s jog stick can. Older sets put them on the front-left bezel or the side. Those rear buttons cover power, volume and input only. Reaching the network menu means a remote or a paired phone; if the set has never been online, Ethernet is the way through first-time setup.

Why would a remote app fail to find my Vizio TV?

The recurring Vizio pattern in support threads is an update that resets network settings or breaks HDMI input detection, after which the app can no longer find a TV it controlled the day before. It reads like a hardware fault and is not one. Unplug the set at the wall for a full sixty seconds, then re-enter the Wi-Fi password rather than assuming it was kept. If the update was interrupted midway, clearing network settings and reconnecting is the documented next step.
