Description
Why choose the LH4341UHS-B2
A compact 43" commercial display built for continuous use.
The ProLite LH4341UHS-B2 is the smallest model in iiyama's LH-series, which also includes the 50" ProLite LH5041UHS-B2AG, the 55" ProLite LH5541UHS-B2 and the 65" ProLite LH6541UHS-B1AG. It shares the same IPS panel technology as the 55" model, giving wide 178°/178° viewing angles and natural colour reproduction — a strong fit for smaller retail units, reception desks, meeting rooms and spaces where the screen is viewed from multiple angles.
A metal housing and fanless design support genuine 24/7 duty cycles, and orientation can be switched between landscape and portrait, so the same SKU covers both a horizontal advertising screen and a vertical menu board. Browse the full 43" commercial displays range for alternative brands and specs at this size.
- 500cd/m² IPS panel with 4K UHD resolution
- Metal housing for commercial durability
- Built-in media player, no external device required
- LAN control for remote OSD management
- VGA input alongside HDMI x3, for legacy source compatibility
Key features
Seven things that matter most when specifying this display.
From panel technology to mounting, everything on the LH4341UHS-B2 is built for commercial duty cycles rather than domestic ones.
24/7 Operation
Rated for continuous, non-stop use with a fanless design and a 50,000 hour panel lifetime reference.
IPS Panel
Wide 178°/178° viewing angles and natural, accurate colour reproduction, well suited to colour-critical or off-axis viewing positions.
Built-In Media Player
Play video, images and audio directly from a USB drive or internal memory — no separate media player needed for single-screen deployments.
LAN Control
Adjust display OSD settings over the network via RJ45, useful for managing screens remotely across a multi-site rollout.
Metal Housing
A metal bezel adds durability over plastic-housed consumer alternatives, supporting long-term commercial deployment.
VESA 200x200 Mounting
Standard VESA pattern, compatible with ScreenMoove's wall mount range.
Portrait & landscape
One display, every orientation.
Rotate via HDMI to switch between advertising-style landscape content and menu board or wayfinding portrait content.
Landscape
Standard orientation for advertising, wayfinding and meeting room content.
Portrait
Ideal for menu boards, wayfinding directories and narrow retail spaces.
Portrait, angled
Compact 43" footprint suits narrow corridors and boutique retail spaces.
Angled view
Consistent IPS colour and contrast held across wide viewing angles, in either orientation.
Note: the built-in media player is not supported in pivot (portrait) mode. Portrait installs relying on internal playback should plan for an external media player or CMS device.
Build & connections
VGA, HDMI x3, RS-232C, LAN, IR and USB.
A slim metal-bezel build with a full accessory bundle included in the box, so there's nothing extra to source before installation.
Rear panel
VGA x1, HDMI x3 (2.0, max 3840x2160 @60Hz), mini jack audio in, RS-232C, RJ45 LAN, IR loop through, RCA audio out and speakers 2x10W.
Metal bezel build
A slim-profile metal bezel keeps the display discreet for retail and reception installs, without compromising on connector count.
Slim side profile
Low-depth mounting profile suited to close-to-wall installs where clearance is limited.

Frequently asked questions
iiyama LH4341UHS-B2 FAQs.
Is the iiyama LH4341UHS-B2 suitable for 24/7 use?
Yes. The LH4341UHS-B2 is rated for continuous, non-stop operation with a 50,000 hour panel lifetime reference, a fanless design and a metal housing, unlike consumer televisions typically rated for 8-16 hours of daily use.
Is the LH4341UHS-B2 an IPS or VA panel?
IPS. This gives wide 178°/178° viewing angles and natural colour reproduction, with a 1200:1 static contrast ratio — the same panel technology used on the 55" LH5541UHS-B2 in the same series.
Can the LH4341UHS-B2 be mounted in portrait orientation?
Yes. The built-in media player is not supported in portrait (pivot) mode, so portrait installs relying on internal playback should plan for an external media player or CMS device instead.
What is the difference between the LH4341UHS-B2 and other LH-series sizes?
The LH4341UHS-B2 is the 43" model in iiyama's LH-series. The same series also includes the 50" ProLite LH5041UHS-B2AG, which uses a VA panel, the 55" ProLite LH5541UHS-B2, which uses IPS like this model, and the 65" ProLite LH6541UHS-B1AG.
Does the LH4341UHS-B2 support VGA as well as HDMI?
Yes. Alongside HDMI x3 (2.0, max 3840x2160 @60Hz), the LH4341UHS-B2 includes a VGA input (max 1920x1080 @60Hz) for legacy source compatibility, plus RS-232C and LAN for control and monitoring.
What VESA mount does the LH4341UHS-B2 use?
200 x 200mm — smaller than the 400x400mm pattern used on the 50", 55" and 65" models in the same series. iiyama's own MD-WM2020 wall mount supports this pattern up to 50kg.
Can ScreenMoove install the LH4341UHS-B2 for us?
Yes. ScreenMoove offers digital signage installation services covering site survey guidance, mounting, cabling and commissioning.
