iiyama LH8664UHS-B3AG 86-inch 4K commercial display

It fits large-format signage that runs unattended and needs to be managed remotely: a reception or foyer wall, a canteen board, a retail floor, a concourse, a queue or departure display, or a large meeting space driven from a laptop. It is a commercial panel rated for continuous operation rather than a television, and at 86 inches it is read across a room rather than from a desk.

They are two revisions of the same 86-inch screen and we sell both. Physically they are identical in the ways that matter to an installer: 47.9kg, the same dimensions, the same mounting pattern, the same IPS panel at 500 cd/m2 and 1200:1, the same 2 x 16W speakers and the same 24/7 rating. This B3AG adds a newer Android release with iiControl device management and iiShare, 4GB of memory against 2GB, 32GB of storage against 16GB, and a USB-C input, and it draws 277W typically. The earlier B2AG has three HDMI inputs rather than two and draws 145W. Choose this one for management and one-cable connection, the B2AG for running cost.

The panel is 47.9kg on its own and 62.2kg boxed, measuring 1937.8 x 1108.8 x 79.6mm. Two people is the minimum and three is more realistic once it is being lifted onto a wall at height, with suitable access equipment. Check the delivery route in advance, because a box nearly two metres wide does not fit every stairwell, corner or lift.

A wall that can carry 47.9kg plus the bracket in shear at height: solid masonry, concrete, or a stud wall with steel reinforcement or a backing plate. Plasterboard with cavity fixings is not suitable for a panel this size. Have the fixings specified for the actual wall build, and check the bracket against the mounting pattern shown in the specification table on this page as well as its load rating.

No. Android 14 is built into the display on 4GB of memory and 32GB of storage, with iiSignage2 for content management, iiControl for device management, iiShare and EShare for wireless sharing, iiBrowser, a media player, a file manager and FailOver input recovery, plus TeamViewer for remote support. Two HDMI 2.0 inputs and a USB-C input are there if you would rather drive it from an external player, a room PC or a laptop.

Two HDMI 2.0 inputs taking 4K at 60Hz, with CEC on both and audio return channel on the first, plus one USB-C input carrying DisplayPort Alt Mode 1.2, data and 15W of power delivery. There are two USB 2.0 ports, a 3.5mm headphone jack and 2 x 16W speakers. For control there is 10/100 wired LAN, an RS-232c port on a 2.5mm sub-mini jack and an IR input, with WiFi 5 on 2.4G and 5G.

Yes. iiyama lists both orientations for this model, so the same screen works as a wide wall display or as a tall directory, wayfinding panel or menu column. Set the orientation in the display settings and lay the content out to match before it goes up, and confirm the bracket you choose is rated for that orientation.

No. At 500 cd/m2 this is a standard indoor signage brightness, correct for a foyer, a corridor, a canteen or a retail interior, but not for a shop window or a glazed atrium with daylight falling on the screen, which calls for the high-brightness tier at around 800 cd/m2. Measure the light at the actual position before you commit to it.

Around 277W in typical use, 0.5W in standby and 0.3W switched off, at energy class G. That is roughly double the earlier B2AG revision of the same screen, which is the trade for the newer processor, the larger memory and the added management software. On a screen running continuously, and across several sites, it is worth costing out before you standardise on one revision.

Yes. iiyama rates it for 24/7 non-stop operation with a 50,000 hour MTBF figure. It is fanless, so it stays silent in a quiet reception, and it has anti image retention for layouts with fixed elements such as a logo, a header bar or a static sidebar. The operating temperature range is 0 to 40C, which is worth checking if it is going into a recess, a bulkhead or a glazed space where air does not move.
