iiyama LH5564UHS-B1AG 55-inch 4K commercial display

Consider it for a reception wall, a retail floor, a canteen, a waiting area or a corridor junction where content is read across a room. It is a commercial signage display built to play managed 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 foyer, a retail floor or a corridor away from the sun. A glazed shop front or a sunlit atrium needs the high-brightness tier instead, so measure the light at the position and ask us before committing to a window.

Yes, better than the panel brightness alone suggests. The VA panel is rated at 5000:1 static contrast, so blacks stay dark instead of lifting to grey, which is what makes video and photography hold up in a dim foyer or an evening retail floor. Contrast, not size, is usually what decides whether a signage screen looks expensive or cheap across a room.

Yes. iiyama lists landscape and portrait orientation for this model, so the same display works as a horizontal information 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. Anti image retention also makes a static logo or a fixed banner 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, plus RS-232C and IR control inputs for a room control system.

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.

The chassis is 1238.4 x 709.2 x 70mm and 13kg without its box, 18.5kg boxed, and a wall mounting kit is supplied. Treat it as a two-person lift onto a bracket. Allow for a 135W typical draw, a socket within reach and a wall that can carry the load, and keep the rear connections accessible for service.

Both use the same VA panel at 5000:1 contrast, the same 500 cd/m2 brightness, the same Android 14 platform and the same 2 x 10W speakers, so this is a pure size and install decision. The 55-inch is 13kg and draws 135W typical; the 65-inch is 17.7kg and 184W, and needs a larger mounting pattern and a stronger wall. Choose the 65-inch if the furthest reader is across a wide foyer, and the 55-inch if the room is ordinary sized or the wall and the budget are the constraint.
