This article covers エレコム KVMスイッチ hdmi usb 切替器 スピーカー 手元スイッチ 2台 KVM-HDHDU2.

Overview

The ELECOM KVM-HDHDU2 is a 2-port KVM switch designed for users who want to share a single HDMI monitor, USB keyboard, and mouse between two computers. It is a practical solution for desks where both a desktop PC and a laptop are used regularly, helping to reduce cable clutter and eliminate the need to unplug and replug peripherals.
On the PC side, the unit provides two HDMI Type-A male connectors, four USB Type-A male connectors, and two 3.5mm stereo mini male jacks. On the peripheral side, it offers one HDMI Type-A female port, two USB Type-A female ports, and one 3.5mm stereo mini female jack. The maximum supported resolution is 1920×1200 (WUXGA) in widescreen and 1600×1200 (UXGA) in 4:3 aspect ratio, which is adequate for office work, web browsing, and general productivity tasks. The switch is bus-powered, with a maximum power consumption of just 2.65W, so no external AC adapter is required.
Switching between the two PCs can be done in three ways: using the included remote switch, pressing hotkeys ([Ctrl]×2+[Enter] or [ScrollLock]×2+[Enter]), or double-clicking the mouse scroll button. Note that the hotkey and mouse switching methods require initial configuration.

Connectivity & Compatibility

The KVM-HDHDU2 supports Windows 10, Windows 8.1, Windows 8, Windows 7, Windows Vista (up to SP1), and Windows XP (up to SP3) in both 32-bit and 64-bit versions. On the Mac side, it works with Intel Macs running Mac OS X 10.3 or later and macOS 10.12 or later, as well as PowerPC Macs with Mac OS X 10.3 through 10.5.
If your computer has a DVI-D 24-pin or DVI-I 29-pin display output instead of HDMI, you will need a conversion adapter. The switch assumes that each connected PC has a standard HDMI Type-A output port.
The two USB ports on the peripheral side are suitable for connecting a keyboard and a mouse. A 3.5mm stereo mini jack allows you to connect speakers, and the audio output switches along with the video and USB signals.

Product Info

The KVM-HDHDU2 was released in November 2011 and has remained a popular choice over the years. It sits in the entry-to-mid tier of HDMI KVM switches, offering the essential features needed to switch between two PCs at a reasonable price point.
The product comes with a one-year warranty. Since it is bus-powered, there is no need for an AC adapter, which keeps the setup clean and straightforward.

Best Use Cases

  • Users who alternate between a desktop PC and a laptop on the same monitor: the remote switch provides instant switching, and the keyboard and mouse are shared between both machines. Not suitable for those who need 4K resolution or DisplayPort connectivity.
  • People who want to reduce desk clutter: this switch consolidates the monitor, keyboard, mouse, and speakers for two PCs into a single set. Those who need to connect many USB peripherals may find the two ports limiting.
  • Users who prefer multiple switching methods: in addition to the remote switch, hotkey combinations and a double-click on the mouse scroll button can be used. For those who want a plug-and-play experience without any configuration, the remote switch is the most straightforward option.
