How to Set Up IPTV & TiviMate on ONN 4K Pro (2026 Step-by-Step Guide)

In 2026, the Walmart ONN 4K Pro Google TV Streaming Device ($49.88) has quickly dethroned the Firestick 4K Max as the most recommended streaming box on Reddit and cord-cutting forums. Powered by Google TV OS with hands-free voice control, 32GB of internal storage, a built-in Ethernet port, and a USB 3.0 expansion slot, it offers flagship performance at a fraction of the cost.

When paired with a premium IPTV service like ViviMate 22,000+ 4K Live Channels, the ONN 4K Pro delivers instant channel switching, smooth 60FPS sports streaming, and seamless EPG loading without heating up or buffering.

Before installing TiviMate or IPTV Smarters Pro, you must unlock developer permissions on your Google TV interface:

1. Turn on your ONN 4K Pro box and select your profile icon in the top right corner.

2. Navigate to Settings > System > About.

3. Scroll down to Android TV OS Build and click the Select button 7 times quickly until a popup reads: 'You are now a developer!'.

4. Return to Settings > Apps > Security & Restrictions > Unknown Sources, and toggle Downloader to ON.

Unlike Fire OS devices, the ONN 4K Pro runs official Google TV, allowing you to install TiviMate directly from the Google Play Store or via Downloader codes:

Method A (Google Play Store): Open Google Play Store on your ONN 4K Pro home screen, search for 'TiviMate IPTV Player', and click Install.

Method B (Downloader Code): Open Downloader app, enter code 278077 (TiviMate Official APK), and click Download & Install.

Once installed, open TiviMate, select Add Playlist > Xtream Codes API, and enter your ViviMate 24-Hour Free Trial Credentials (Server URL: http://line.vivimate.best:8080).

Some ONN 4K Pro users report audio sync delay or silent channels on certain Dolby AC3 / Surround Sound audio streams. Here is how to fix it:

1. Fix Audio No Sound / Lag: Open ONN 4K Pro Settings > Display & Sound > Advanced Sound Settings. Switch audio output from Automatic to Manual, enable PCM stereo output, and turn off Dolby Digital Passthrough if your TV lacks a soundbar.

2. Optimize TiviMate Playback: Inside TiviMate Settings > Player, set Video Decoder to Hardware and Audio Decoder to Software. This forces the ONN 4K Pro CPU to decode AAC/AC3 audio tracks perfectly without dropped frames.

One major advantage of the ONN 4K Pro over Amazon Firestick is its built-in USB 3.0 port. You can easily record live PPV sports and TV shows directly to a USB drive:

1. Insert a 64GB or 128GB USB 3.0 flash drive (formatted to FAT32 or exFAT) into the back of the ONN 4K Pro.

2. When prompted on screen, select 'Format as Device Storage' or 'Use as Removable Storage'.

3. Open TiviMate > Settings > Other > Recording > Recording Folder, and select your external USB drive path.
