Questions

Can’t find your answer? Ask on WhatsApp

Does the LDH55-SAI400TL support touch on a 55-inch screen?

Yes. The 55-inch panel uses capacitive touch with 10 touch points and a response time of 8 ms or more, so it suits interactive directories and wayfinding with finger input.

Can the LDH55-SAI400TL be mounted in portrait?

Yes. The display supports landscape and portrait modes. It mounts on a wall using a 400 x 400 mm VESA pattern, and the wall-mount bracket, remote control and user manual are supplied in the box.

Does it play 4K content without an external media player?

Yes. Its Android 11 system and quad-core A55 processor decode H.265 HEVC video up to 2160p at 60 fps. Content can be stored in the 32 GB internal memory or on a TF card of up to 128 GB, and the display connects over Ethernet or Wi-Fi.

How are several displays managed from one place?

The manufacturer describes a unified platform based on B/S architecture. It schedules programs by time and location, generates operation reports and allows the platform to control each display remotely. The B/S (browser/server) design means management runs through a web browser rather than software installed on each display.

Which inputs and network ports does it have?

It has one HDMI 2.1 input at 4K and 60 Hz, one 3.5 mm audio output, one RJ-45 Ethernet port at 10/100/1,000 Mbps, Wi-Fi 802.11 a/b/g/n/ac/ax, one USB 2.0 port, one USB 3.0 port and a TF card slot.
