iiyama LH4360UHS-B2AG 43-inch 4K commercial display

It suits a single-screen job in a room people move through: a canteen menu, a reception welcome board, a departure or appointment list, a corridor notice point or a small retail display. It is a commercial signage display rated to run continuously, with content management on board, rather than a television pressed into service.

No. Android 11 is built in with iiSignage2 content management, EShare wireless sharing and FailOver input recovery, and 802.11ac wireless is on board, so a playlist can be scheduled and updated over the network. Three HDMI 2.0 inputs are there if you would rather drive it from an external player or a PC, which is the better route for demanding content.

For what this display is built to do, yes. Scheduled playlists, still artwork, looped video and simple zoned layouts run comfortably on 2GB of memory and 16GB of storage. A live web dashboard, a page with many concurrent data zones or a complex browser application will not, and that content is better driven from an external player over HDMI.

Yes. iiyama rates it for 24/7 non-stop operation with a 50,000 hour MTBF figure, it is fanless so it makes no noise, and anti image retention protects against fixed elements such as a logo or a header bar marking the panel. That duty rating is the practical difference between this and a consumer television.

No. At 500 cd/m2 this is an indoor panel, suited to a foyer, a canteen, a corridor or a retail interior out of direct sun. A window position or a glazed frontage with daylight falling on the screen needs the high-brightness tier at around 800 cd/m2. Measure the light where the screen will actually hang before you decide.

Yes. Both landscape and portrait orientation are listed for this model, so it works as a tall wayfinding or directory panel as well as a wide menu board. Set the orientation in the display settings and design the content to match before the screen goes on the wall.

A wall mounting kit with a mounting guide, screws and screw anchors, along with a remote control. The mounting pattern the kit matches is listed in the specification table on this page. That covers a straightforward flat-wall install; a tilting mount, a portrait mount or a floor stand would be an extra.

Three HDMI 2.0 inputs, each accepting 3840 x 2160 at 60Hz, two USB 2.0 ports, a 3.5mm audio output and 2 x 10W speakers. Control runs over wired LAN or RS-232c, and 802.11ac wireless is built in. There is no DisplayPort or USB-C input on this model, so a source with USB-C video output needs an adapter.

Around 45W in typical use, 0.5W in standby and 0.3W switched off, for an energy rating of class E. That is notably better than most of iiyama's signage range and, on a screen that runs continuously across several sites, it is a figure worth multiplying out at the specification stage.

Choose by viewing distance and by how the screen will be handled. Both are 4K UHD, 500 cd/m2, 24/7 rated, fanless, rated 4000:1 for contrast and run Android 11 with iiSignage2 on 2GB of memory and 16GB of storage, and both include a wall mounting kit. The 43 inch weighs 9.1kg, has a plastic housing and draws 45W typically at energy class E. The 55 inch weighs 17.6kg, is a two-person lift, uses metal at the front and draws 55W typically. Go up a size when people read the screen from more than a few metres away.
