LDV65-HAI400L-M

A 65-inch portrait display for continuous signage

The Dahua LDV65-HAI400L-M is a 65-inch vertical LCD from the Pro Series, supplied with its base and used in portrait orientation. Its 9:16 aspect ratio suits tall menus, wayfinding columns and queue information, where a landscape screen leaves most of its area unused. Each unit carries its own Android 11.0 player, so content runs on the screen itself rather than from a separate computer.

Panel and playback figures that matter

The IPS panel resolves 2160 (H) × 3840 (V) pixels, with 500 cd/m² typical brightness, 1200:1 typical contrast and 178° viewing angles in both directions. Its 8 ms typical response time suits moving graphics, and a 1% haze surface treatment is specified for the screen face. Colour is rendered at 10 bit using 8-bit plus FRC, which equates to 1.07 billion colours. The quad-core A55 processor running at 1.92 GHz, with 4 GB RAM and 32 GB storage, decodes H.265 and VP9 up to 2160p at 60 fps and H.264 up to 2160p at 30 fps, so 4K loops play without an external player.

Scheduling, split screens and remote control

Intelligent split-screen mode lets you rearrange page zones and adjust the layout for different scenes on the same panel. The device is built on a browser-based platform architecture that manages programmes by time and location, allows remote control through the management platform, and generates operation reports, so facilities teams can confirm that each screen ran as scheduled. Programmes can be released in several playback modes. The connections are:

• One RJ-45 Ethernet port, self-adaptive at 10/100/1000 Mbps
• Wi-Fi through an optional external module; no Bluetooth
• One HDMI 2.1 input supporting 4K at 60 Hz; no video output
• One USB 2.0 and one USB 3.0 Type-A port, plus a TF card slot up to 128 GB
• One 3.5 mm audio output and two built-in 5 W speakers
• IR receiver for the included remote, and a built-in AC power socket

Where it fits across Qatar

In a Doha shopping mall, a portrait screen beside a store entrance can run promotions and directions throughout the day, with its schedule set from the office rather than by staff visiting each unit. In a clinic in Al Sadd, the same format can show queue numbers and department maps in a waiting area. In a hotel lobby in West Bay or a bank branch in Msheireb, it can display event listings and service information from a fixed, air-conditioned position.

What to plan before you order

With a net weight of 68 kg and a height of 2050 mm, this is a heavy floor-standing unit. Plan a level, stable position and a clear route through doorways and lifts for the 83.7 kg packed weight. SmartRooms Qatar offers a free site survey, which is useful for confirming floor space, power points and the rear 200×200×100 mm area reserved for a media box or mini PC.

The operating range is 0 °C to +40 °C, and the manufacturer advises avoiding direct sunlight. Summer temperatures in Qatar can exceed 45 °C, so keep the unit indoors in air-conditioned space, away from sun-facing glass, and confirm the exact spot with the SmartRooms Qatar team before installation. The power supply accepts 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains, and draws no more than 140 W. The product carries CE EMC, CE LVD and CE ERP certifications.
