Professional display 43”, 4K UHD, media player, 18/7 – iiyama ProLite LE4341UHS-B1

Professional display 43” iiyama ProLite LE4341UHS-B1, 4K UHD, media player, 18/7

iiyama ProLite LE4341UHS-B1 is a professional display 43″ 4K UHD designed for digital signage, corporate spaces, education, HoReCa and retail. The black, glossy, thin frame casing makes it look premium on the wall, on a stand or in a totem, and the IPS 4K (3840 x 2160) panel renders content with a high level of detail and rich colors.

4K UHD resolution offers four times more detail than a Full HD screen, which means clear text, very well-defined images and the ability to display multiple content areas simultaneously – promotions, logo, banner news, menu, corporate information, etc. The brightness of 350 cd/m² and the static contrast of 1200:1 ensure very good visibility in bright indoor spaces, such as showrooms, malls, receptions or conference rooms.

The IPS panel with 178°/178° viewing angles ensures a clear and legible image from almost any position, which is extremely important in signage: passersby, customers or conference participants see the same correct content, no matter where they look.

A great advantage is the integrated media player. You can play video clips, images and presentations directly from a USB stick or internal memory, without having to keep a PC or external player permanently connected. In practice: copy the content to USB, connect it to the display, configure the playlist and your campaign runs automatically at the set times. Ideal for digital menus, promotional campaigns, info-screens or displays in public spaces.

The display is designed for 18/7 operation, i.e. up to 18 hours a day, 7 days a week, with fanless design (without a fan), which means silent operation and fewer moving mechanical parts – important for reliability in commercial environments.

Inside you find a integrated 2 x 10W audio system, powerful enough for announcements, audio spots, presentations or voice messages in showrooms and conference rooms. If you need even more acoustic pressure, you can easily connect an external audio system via the RCA output.

Professional connectivity for digital signage

iiyama ProLite LE4341UHS-B1 comes with a full range of ports for integration into any signage project display:

• 3 x HDMI 2.0 – for 4K media players, PCs, signage players, TV decoders or wireless presentation systems;
• 1 x VGA – useful for older equipment or integration into existing infrastructures;
• mini-jack audio input for analog source;
• RCA audio output (L/R) – for connecting an external audio system;
• RS-232C in/out – for remote control, integration into centralized management systems (BMS, room control, professional AV solutions);
• LAN (RJ45) – for configuration and management via network;
• IR in / IR loop through – for IR control centralized and cascading.

The USB 2.0 port allows both firmware updates and media playback through the integrated player, so the screen can function as a standalone solution, without having to depend on a dedicated PC.

Advanced features for image management and protection

As a professional signage display, the LE4341UHS-B1 has features dedicated to the commercial environment:

• scheduling – set the start and stop times to display content only when you need it;
• clock & timer – useful in corporate or DOOH scenarios;
• pixel shift and anti image retention – reduce the risk of image retention/burn-in when displaying static elements (logos, bars, frames);
• auto signal detection & auto play – automatically starts content when it detects a signal or media on USB;
• HDMI CEC link – simplified control with a single remote control in certain configurations.

The OSD menu is available in multiple languages ​​and offers detailed control over the image (format, color temperature, noise reduction, dynamic contrast, gamma, brightness, sharpness), sound (bass, treble, balance, audio out) and management (ECO mode, auto power off, network standby, power management, local keyboard lock, RC lock, monitor ID, LED, etc.).

Flexible installation and integration into projects

The ProLite LE4341UHS-B1 is designed for landscape mounting and is compatible with the VESA 400 x 400 mm standard, which makes it easy to install on supports wall mounts, mobile stands or dedicated structures.

The black plastic housing with a glossy frame helps it integrate elegantly into lobbies, receptions, premium stores, restaurants or corporate spaces. Thanks to the thickness of only 67.5 mm, the screen does not look massive on the wall and fits even in narrower spaces.

The display is certified for an operating temperature between 0 and 40°C, with a storage temperature from -20 to 60°C, which provides flexibility in different indoor environments. With an MTBF of 50,000 hours (without backlight), it fits very well in long-term projects.
