Pixel-accurate 4K Resolution

The IMBA-H420 is equipped with three display output connectors, including HDMI™, internal DP++ and VGA. The HDMI™ and DP++ interfaces support pixel-accurate 4K resolutions for high-end applications while the VGA is reserved for legacy devices.

Internal DP++

(up to 4096 x 2304 @ 60 Hz)


(up to 4096 x 2304 @ 30 Hz)


(up to 1920 x 1200 @ 60Hz)

DP++ Supported

The IMBA-H420 provides various display outputs for customers to connect to a device with the same native interface to avoid quality loss. However, when conversion is needed, the equipped DisplayPort Dual-Mode (DP++) connector allows the use of a simple, inexpensive passive adapter to convert to HDMI™. It is completely plug and play, handles both video and audio, and does not need any driver to work.

Rich Expansion Options

Bringing together PCIe 3.0 technology and legacy PCI standard creates endless possibilities in developing a wide range of solutions. A graphics card or AI card can be added via the PCIe x16 for sophisticated applications, like medical diagnosis, machine vision, robotics or AI-based projects.

Four PCI slots are also provided to maintain backward compatibility. Legacy systems in machine controllers, test rigs, real-time simulations or many other PC-based applications can be upgraded easily without a full rebuild.

Tap into the Power of AI

In recent years, Edge AI has became a virtual role. We are now at a time where AI is revolutionizing the world. The IMBA-H420 can deliver excellent computing capabilities to accelerate AI adoption in food/fruit inspection, factory automation and test equipment. By adding IEI's Mustang accelerator card, it could be used for deep learning inference computing to help you get faster, deeper insights for your customers and your business.

2.5GBASE-T Ethernet Technology

The 2.5GBASE-T speed is a contemporary solution to an old problem due to the increases in throughput. Enterprises that choose the IMBA-H420 as their solutions for the implementation of 2.5GBASE-T technology will benefit from a simple change that achieves a noticeable gain in bandwidth, while at the same time realizing cost savings from reuse of existing Cat5e cables.

Energy Efficiency

As shown in the following table, the IMBA-H420 is compliant with ErP, which requires a system should not consume more than 0.5 W during off state or standby. The IMBA-H420 consumes nearly no energy in sleep mode or shutdown, making it a green and eco-friendly product that saves cost and electricity.

Touch-enabled BIOS

The BIOS menu in the latest IEI products is re-designed to a touch-enabled user interface to eliminate excessive steps and unnecessary keyboard connection. It allows users to navigate with finger on a touch-enabled monitor to make BIOS configuration easily. The new design features the followings:

Graphical interface

BIOS menus is transformed from text-based to graphical user interface, making it intuitive and easy to navigate.

Shortcut to boot device setup

The main menu provides quick access to the boot device configuration, helping users save time on boot option priority setting.

Easy-access function keys

The BIOS function keys are arranged vertically on the side of the screen and indicated by icons, so that users can access them without the need of using a keyboard.

On-screen keyboard

An on-screen keyboard is available when it is needed to enter text in BIOS, such as administration password setup.
