MAG540w3 Review — High-Performance Linux IPTV Set-Top Box by Infomir

The latest generation of Infomir’s MAG series brings powerful hardware and reliable software in a compact Linux-powered set-top box designed for IPTV and streaming applications. Built with performance, compatibility, and long-term stability in mind, these devices are a solid choice for operators and home users who want smooth 4K playback and flexible integration options.


What’s in the Box

When you unbox the MAG540 series set-top box, you’ll usually find:

  • The MAG540 or MAG540w3 unit

  • IR remote control (programmable)

  • 2× AAA batteries

  • HDMI cable

  • Power adapter

  • User manual
    This complete kit ensures you can get up and running quickly right out of the box.


Design & Build

These MAG models have a sleek black case that fits easily into any entertainment setup. The front panel includes an IR sensor and LED indicator, while the rear and sides offer essential ports for connectivity: USB, Ethernet, HDMI, and, on the w3 version, built-in Wi-Fi support.


Hardware & Performance

At the heart of the device is a quad-core ARM Cortex-A35 CPU paired with the Amlogic S905Y4 chipset, which delivers responsive performance and efficient media decoding. With 1 GB of RAM and 4 GB of eMMC storage, the set-top box handles user interfaces and apps smoothly, even during long sessions.

  • Operating system: Linux 4.9 — stable and lightweight

  • Video output: Up to 4K @ 60 fps

  • Video codec support: HEVC (H.265) for efficient streaming

  • Ports: HDMI 2.1, Ethernet, 2× USB 2.0

  • Network (MAG540w3): Dual-band Wi-Fi + Ethernet

  • Network (MAG540): Wired Ethernet only
    This combination ensures fast performance without frequent reboots or lag.


Streaming & Compatibility

MAG540 devices support a wide range of IPTV and OTT formats. Thanks to HEVC and modern video processing, 4K content streams smoothly, even at relatively modest bandwidths. The Linux OS makes the interface responsive and installer-friendly.

You’ll also find:

  • Support for popular streaming middleware

  • USB connectivity for keyboards, mice, or external storage

  • Broad codec compatibility, including 3D formats and image display
    These features help make the set-top box versatile for different use cases — from home entertainment to customized operator deployments.


Audio & Multimedia

The device supports Dolby Digital Plus™, allowing an immersive multi-channel audio experience when connected to compatible sound systems. With USB ports available, you can also play local media files or expand your setup with peripherals.


Connectivity & Setup

  • Ethernet: Reliable wired connection for streaming

  • Wi-Fi (w3 version): Dual-band (2.4 GHz & 5 GHz) for flexible placement
    Setting up is straightforward — just connect it to your TV’s HDMI port, plug in the network, and follow the on-screen instructions. Remote control programming is easy, and the interface feels intuitive for most users.


Why It Stands Out

Compared with older MAG models, the MAG540 line is significantly more powerful and efficient thanks to the newer chipset and improved network features. It’s designed to run for months continuously, with an interface that remains responsive even under heavy use.


Who It’s For

This set-top box is ideal for:

  • IPTV operators seeking a customizable Linux platform

  • End users who want robust 4K streaming without complicated setups

  • Smart home setups needing reliable network media playback

Whether used in a home theater or integrated into a larger IPTV service, the MAG540 lineup balances performance and simplicity effectively.
