iiyama LE4341S-B2 43-inch commercial display

Consider it for a reception, a corridor, a canteen, a waiting area or a back-of-house board where a 43-inch screen has to show content that something else generates. It is an entry-level signage panel: no computer inside, no scheduling on the screen, just a bright indoor display with three inputs and proper commercial control. That makes it cheap per screen when a central player or a PC already exists.

Yes. iiyama's specification for this model lists no integrated software, so nothing on the display stores content, schedules it or connects to a signage service. A player, a PC, a signage box or a switcher feeds it over one of the three HDMI inputs. That hardware, and any subscription it needs, is a separate line on the quote.

No. iiyama lists landscape orientation for this model and does not list portrait. If a vertical format matters, or might matter later, look at the LH41 models in the same range, which are listed for landscape or portrait. This is the single biggest specification difference between this display and its neighbours, so settle it before ordering.

Indoors, away from direct sun. 350 cd/m2 is comfortable in a lit foyer, an office, a corridor or a canteen. It is not enough for a shop window, a glazed atrium or any position where daylight lands on the glass, which is what the high-brightness tier at around 800 cd/m2 exists for. If you are not sure, measure the light at the actual position before you commit.

It has RS-232C, an RJ45 network connection and an IR input for monitor control, so power, input and volume can be driven from a control processor or over the network rather than by hand. A remote control with batteries is supplied in the box for local use, along with cable management.

Three. It has three HDMI 2.0 inputs, each rated to 1920 x 1080 at 60Hz, which matches the panel's native resolution. That is enough for a player, a laptop plate and a spare without adding a switcher. Audio comes out through two 10W speakers or an RCA line output to an amplifier.

iiyama does not publish a maximum non-stop operating time for this model, so we will not claim one. Several models in the wider range are rated 24/7 and this one carries no such figure, which is worth knowing before you plan a site that never switches off. What iiyama does quote is a 50,000 hour MTBF figure excluding the backlight and a fanless design. Ask us and we will get the duty cycle confirmed for your deployment.

53W typical, 0.5W in standby and 0.3W switched off. The chassis is 968 x 557.5 x 54mm and weighs 8.4kg without its box, which is a comfortable one or two person lift onto a bracket. Across a large estate the difference between this and a 4K model in the same size is real: the 43-inch LH4341UHS-B2 draws 107W typical.

Yes, two 10W speakers are built in, and there is an RCA left and right line output if the sound needs to go to a ceiling system or an amplifier instead. For a reception or a corridor the built-in pair is usually enough for a short announcement, but not for background music across an open space.

They are the same size and very different screens. This one is Full HD at 350 cd/m2 and mounts landscape only, and iiyama publishes no duty cycle for it. The LH4341UHS-B2 is 4K at 3840 x 2160, 500 cd/m2, rated 24/7, mounts landscape or portrait, has a metal housing and plays media from its own USB port, at 107W typical against 53W. Choose this one when the content is simple, read from a distance and driven from elsewhere; choose the LH4341UHS-B2 when people stand close to the screen, the position is brighter, or it has to run continuously.
