iiyama LH4364UHS-B1AG 43-inch 4K commercial display

Consider it where people read the screen from close range: a reception desk, a service counter, a menu board above a till, a lift lobby, a corridor notice point or a wayfinding panel. It is a commercial signage display built to play content all day in a public space, not a meeting-room screen and not a television.

No. Android 14 runs on the display itself with 4GB of memory and 32GB of storage, iiSignage2 for scheduling and playlists, iiControl for remote device management, iiShare and EShare for casting and a built-in browser, media player and file manager. Two HDMI 2.0 inputs and a USB-C input are there if you would rather drive it from a player or a PC you already own.

No, not for a window with daylight on it. The panel is 500 cd/m2, which is the indoor signage tier and is right for a lobby, a corridor or a counter away from the sun. A glazed shop front or a sunlit foyer needs the high-brightness tier instead, so measure the light at the position and ask us before committing to a window.

Yes. iiyama lists landscape and portrait orientation for this model, so the same display works as a horizontal menu board or a vertical wayfinding panel. Decide which before you order the bracket, and build the content template to match, because rotating a landscape playlist after installation usually means reauthoring it.

Yes. It is rated for 24/7 non-stop operation with a 50,000 hour MTBF figure and no cooling fan, which is what separates a commercial signage display from a consumer television pressed into the same job. It also carries anti image retention, so a static logo or a fixed banner is less likely to leave a ghost on the panel.

Two HDMI 2.0 inputs, each taking 3840 x 2160 at 60Hz, and one USB-C input carrying picture over DP Alt Mode with 15W of power returned down the same cable. There are also two USB 2.0 ports, a 3.5mm audio output, built-in 2.4G and 5G WiFi and wired LAN.

iiSignage2 handles the content, scheduling playlists out to a group of screens, and iiControl handles the hardware, so power states and settings can be changed without visiting each display. TeamViewer is installed for remote support on top of that. All three need the screens on a network your IT team is happy with, so raise it at the design stage rather than on installation day.

Yes. Alongside the network connection there is an RS-232C control input on a 2.5mm sub-mini jack, an RJ45 LAN port and an IR input on a 3.5mm stereo mini jack, so a control processor can switch inputs and power the screen as part of a wider system.

A television is built for a few hours of viewing a day in a living room. This is rated for continuous operation, runs fanless, mounts in portrait as well as landscape, carries anti image retention for static content, accepts wired control from a room system and manages its own content centrally. Over a few years in a public space those are the things that decide whether the screen is still working and still on message.

Judge it on reading distance first. The 43-inch suits a counter or a lobby where people stand within a step or two, and the 50-inch gives readable text a little further back for a modest step in price and weight, 10.4kg against 8kg. There is one real technical difference between them: this 43-inch uses a VA panel rated at 4000:1 static contrast, so blacks hold up well in a dim space, while the 50-inch uses an IPS panel rated at 1200:1, which trades that depth for colour that stays truer when the screen is read from an angle. Everything else, including the 4K resolution, the 500 cd/m2 brightness, Android 14, the 2 x 10W speakers and the 24/7 rating, is the same.
