The HP ProOne 400 G9 VESA mounting kit (manufacturer number 56P78AA) is an accessory module for wall or monitor arm mounting of HP ProOne 400 G9 All-in-One computers. It enables space-saving installation by securing the device to a wall or monitor arm, thereby relieving desk surfaces. The kit is specifically designed for use with the HP ProOne 400 G9 AiO system and provides a stable mounting base with an integrated holder for the power supply.

Applications
This mounting kit is suitable for office environments, workstations with limited space, or for integration into cable-managed workspaces. It is particularly suitable for installations where a clean, orderly, and cable-reduced workstation design is required. Wall mounting reduces the desk space occupied by the computer and supports structured workstation design.

Functions and Equipment in Detail
The kit consists of a VESA plate and a holder for the power supply. The VESA plate is designed for mounting on a wall or monitor arm and features a standard VESA interface with dimensions 100 mm × 100 mm. This interface is widely used worldwide and allows compatibility with a wide range of wall mounts and monitor arms. The integrated power supply holder ensures that the external power supply is securely and stably attached to the device, eliminating the need to place it on the desk. The entire construction is black, ensuring visual harmony with the HP ProOne 400 G9 AiO device.

Technology Explained Simply
The VESA plate features a mounting surface of 100 mm × 100 mm, matching the common VESA standard size. This standard enables compatibility with standard wall mounts and monitor arms that support this interface. The power supply holder is designed to securely fasten the power supply, preventing it from falling. The total weight of the kit is 799 g, with the VESA plate weighing 540 g and the power supply holder 340 g. The dimensions of the VESA plate are 12.3 cm (H) × 11.75 cm (W) × 5.25 cm (D), while the power supply holder measures 18.8 cm (H) × 4.22 cm (W) × 3.95 cm (D). The maximum supported screen size is 23.8 inches.

Compatibility and Accessories
The mounting kit is specifically developed for the HP ProOne 400 G9 AiO computer. It is not intended for other models in the ProOne portfolio or for other manufacturers. Compatibility is limited to ProOne 400 G9 and G10 models. The VESA plate features the standard VESA interface 100 mm × 100 mm, enabling use with a wide range of wall mounts and monitor arms that support this standard.

Installation and Mounting
Installation involves securing the VESA plate to a wall or monitor arm using the VESA screw holes. Then, the HP ProOne 400 G9 AiO device is attached to the VESA plate. The power supply is inserted into the integrated holder and secured. The installation instructions are included in the delivery scope and support the installation process.

Operational Advantages
Wall or monitor arm mounting reduces desk space usage and enables better workstation organization. The integrated power supply holder prevents the power supply from resting on the desk, simplifying cable management and reducing the risk of cable tangling. The stable construction ensures secure fixation of the device, minimizing damage from vibrations or accidental contact. The black finish matches the design of the HP ProOne 400 G9, ensuring a uniform appearance.
