HDMI DisplayPort KVM Switch 4 Computers 2 Monitors - 4K Dual Display

In this review of the HDMI DisplayPort KVM Switch for 4 computers and 2 monitors, the bottom line is simple: it is for users who need to control up to four machines with one keyboard, mouse and dual-monitor setup while keeping very high resolutions. The reviewer found the biggest reason to buy is its support for simultaneous dual-display switching at up to 4K@60Hz and 2K@120Hz, which makes it practical for mixed desktop, office and light creative workflows where screen fidelity matters. Setup is plug-and-play, and the unit includes a remote and external power adapter for stable USB device sharing.

Key Features

• 4-port dual-monitor switching: Lets one set of keyboard and mouse control four computers while sharing two displays in duplicate or extend modes.
• Ultra HD support: Handles up to 4K@60Hz on supported hardware and 2K@120Hz, preserving clarity for text and video on compatible monitors.
• Four USB 3.0 ports: Allows sharing of up to four USB 3.0 devices across machines with up to 5 Gbps transfer speeds and backward compatibility.
• One-touch switching with remote: Switch between machines using the front panel or the included infrared remote, with LEDs showing the active source.
• Stable powered operation: Ships with a 12V 1A external adapter to maintain reliable USB and peripheral performance under load.

Who It's For

This KVM switch is aimed at small offices, developers, IT technicians, and power users who run multiple PCs or workstations and require a reliable dual-monitor setup with high resolution. It is particularly useful when each computer already exposes both an HDMI and a DisplayPort output so the switch can accept the needed inputs.

It is not the best fit for users whose machines lack HDMI+DP outputs, those relying on Bluetooth-only keyboards or mice without USB receivers, or users seeking hotkey switching; the unit uses panel buttons and an IR remote only.

Pros & Cons

Pros

• Supports high resolutions up to 4K@60Hz, preserving visual fidelity across sessions.
• Shares four USB 3.0 devices at up to 5 Gbps and is backward compatible with older USB standards.
• Plug-and-play setup plus included infrared remote and LED indicators make switching straightforward.

Cons

• Requires each computer to have both HDMI and DisplayPort outputs and monitors to include one DP and one HDMI, which may need adapter work for some setups.
• Does not support Bluetooth-only peripherals without a USB receiver and lacks hotkey switching.

Specifications

Our Verdict

For anyone who needs to manage four computers with a single keyboard and mouse and wants reliable dual-display output at high resolutions, this KVM is strong value. It delivers solid 4K dual-monitor support, fast USB sharing and simple switching with a remote, though users must ensure their machines have the required HDMI and DP outputs and accept the lack of hotkey switching.

Frequently Asked Questions

Can I use Bluetooth keyboards and mice?
No. Bluetooth-only devices without a USB receiver are not supported; use wired or USB-receiver peripherals.

Do I need an external power adapter?
Yes. The included 12V 1A adapter is required to ensure stable USB device operation and proper switching.

Will it auto-detect different resolutions?
Yes. The switch can automatically detect resolution differences between inputs when switching sources, but 4K requires HDMI 2.0 and DP1.4 cables and compatible hardware.
