  1. William Bradley –

    I bought this 55-inch Dahua monitor for our security room. The 4K resolution is incredibly sharp, and knowing it’s built for continuous 24/7 operation gives me peace of mind. Delivery from apsardze24.lv was prompt. The built-in speakers are a nice bonus. Highly satisfied with both the display and the service!

    William Bradley –

Is this the Chinese or EU version of the DHI-LM55-F400N?

This is the **Official EU version**. It meets all European regulatory standards, and since Apsardze24.lv is an Authorized Partner, you are guaranteed full regional compatibility and official support.

What is the exact VESA wall mount size for this monitor?

This unit is designed for wall mounting, but specific VESA dimensions can vary by production batch. Please consult the user manual included in the box or contact our technical support at [email protected] for precise mounting specifications.

Does the DHI-LM55-F400N require a mobile app for setup?

No, this is a plug-and-play monitor. It does not use apps like Hik-Connect or DMSS directly; simply connect it to your NVR, DVR, or PC via HDMI or VGA to display your video feed immediately.

Is the image quality good when viewing the screen from the side?

Yes, the VA panel technology offers a 178° wide viewing angle (both horizontal and vertical), ensuring the 4K Ultra-HD resolution remains clear, vivid, and readable from almost any position in the room.

Can the DHI-LM55-F400N record video without an NVR?

No, this monitor is a display device only and does not have internal storage or an SD card slot. To record and store surveillance footage, you must connect it to a recording device like a DVR or NVR.

What happens if the monitor stops working after a year?

We provide a comprehensive **2-Year Warranty** for all clients (Business & Private). Our service center is located in **Riga**, ensuring fast, local repairs without the need to ship the device abroad.

Is it safe to leave the DHI-LM55-F400N running 24 hours a day?

Absolutely. Unlike standard consumer televisions, this Dahua monitor is specifically engineered for 24/7 continuous operation, making it ideal for security centers and constant surveillance monitoring.
