About
iiyama ProLite TF4339AS-B1AG – a touch screen that keeps running
If your business needs a display that runs from open to close — or around the clock — this iiyama ProLite is built exactly for that. The 42.5" open-frame design is made for permanent installations: customer-facing kiosks, order management screens, restaurant dining rooms, or retail information boards. Once it's in place, it simply works.
Sharp 4K image from almost any angle
The screen resolves at 3840 × 2160 pixels. In practice, that means price boards, product images, and booking views stay crisp even when viewed from a distance or from the side. At 500 cd/m² brightness, content stays readable in well-lit spaces — a café counter near a window, a brightly lit shop floor. The 178° viewing angle in both directions means the picture looks right from virtually everywhere in the room.
40-point multi-touch for busy environments
Projected Capacitive touch technology tracks up to 40 simultaneous touch points. In a customer-facing setting, that means multiple people can interact with the screen at the same time without missed taps or delays. Response time is 8 ms.
Android 11 built in — no separate computer needed
The display ships with Android 11, 4 GB RAM, and 32 GB storage integrated. You can run your POS application, digital menu, or self-service interface directly from the screen — no separate PC or media player required. That means fewer devices, less cable clutter, and fewer things that can go wrong.
Connections: USB, RS232, Ethernet, HDMI, DisplayPort
Connectivity is fully covered: three USB ports, an RS232 serial port for legacy integrations, Ethernet for the network, HDMI and DisplayPort for an external source, and an audio connection. The box includes USB and DisplayPort cables, a power supply, and a power cable — the screen is ready to use straight after installation.
IP54-rated and designed for 24/7 operation
The IP54 rating means the screen handles dust and splashing water in daily use. The open-frame construction makes it straightforward to mount inside your own enclosure or a furniture maker's solution. The VESA mount pattern is 200 × 200 mm, so a compatible stand or wall bracket is easy to source. Warranty is three years.
