## Description

The B004-DUA4-HR-K is a 4-Port DVI/USB KVM Switch with audio and USB 2.0 peripheral sharing. It allows you to access, control, boot and reboot four computers from a single USB keyboard, USB mouse, and monitor. Switching between connected computers is quick and simple using keyboard hotkeys or pushbuttons. An independent audio/mic and USB peripheral switching function allows for an uninterrupted experience. A computer can be printing on a printer connected to one of the USB 2.0 peripheral ports, while you listen to audio from and access another computer; all at the same time. The B004-DUA2-HR-K uses DVI-I technology, allowing for the transmission of a digital (up to 1920 x 1200) or analog (up to 2048 x 1536) signal. A DVI to VGA adapter, such as Tripp Lite's P126-000, is required for conversion to an analog monitor. Whichever you use, full time DDC support provides the necessary EDID information required for optimal video performance on Windows 7 and other operating systems. Compatible with all major operating systems. 1-year limited warranty.

Review: Works great! - This is my 2nd Tripp Lite 4 Port KVM. My 1st one still works great after about 8 years but it only has analog ports & I need DVI for our new PC replacements. I plugged in a wireless keyboard/mouse combo (Logitech P/N 820-006477) & it handles it just fine. This came with 4 video & USB cables but they were separate and not the same length. I had a lot of extra zip ties laying around so I made up 4 cables with a loop in the middle to take up the extra length of the USB & make all the ends meet. This keeps everything neat & tidy behind my desk so nobody trips over them - including me. One nice touch I didn't have with the old one is the USB ports on the front & back of the unit. Whatever is plugged in is shared to any machine attached.
Review: It works great. Very happy with it. - I needed a KVM with digital i/o to replace an older VGA kvm switch. I connect a variety of different devices for IT configuration and troubleshooting, each with different inputs and resolutions. This little unit has been great. It does not use emulation, which means switching inputs is a bit slower than others I've used. However, sometimes emulation can result in mismatched screen resolutions when switching inputs as devices boot, so I'd gladly sacrifice a few seconds in favor of reliable and predictable screen output. Also, unlike many units in this price range, this KVM has automatic cycling between inputs, which is helpful when you're monitoring the progress of multiple installs.

### ⭐⭐⭐⭐⭐ Most stable KVM I've found
*by P***X on April 3, 2019*

I've used (and discarded) several KVMs over the years, most of them inexpensive. The Tripp Lite B004-DUA4-HR-K has so far proven to be the most robust and solid with regards to switching. Here's the configuration I have it in currently: Monitor: NEC LCD2490WUXi (1920x1200 resolution) Keyboard: Razer BlackWidow Ultimate 2013 (see note below on this) Mouse: Roccat Kone Pure (connected via Razer BlackWidow's port) Speakers: Logitech 2.1 system Systems: 1 - PC (AMD Ryzen 1700x + ASRock x370 Taichi + Nvidia GTX1080 EVGA FTW GAMING) 2 - 2015 MacbookPro, through Caldigit Thunderbolt 2 hub, connected via Apple Mini DisplayPort to DVI adapter 3 - 2009 MacPro + Nvidia GTX 680 (Mac edition) 4 - 2001 MacPro + Nvidia GTX 280 (Mac edition) Set up was fairly straightforward. Mac use has been flawless so far, but had a few issues on the Windows side: - I had to disable mouse emulation mode on the PC channel, otherwise it would only move in a horizontal direction. - Like an idiot I installed Razer's Synapse 2.0 software, hoping to be able to program the KVM's switching sequence (scroll-lock, scroll-lock, [number], enter) as a macro. Ironically, this rendered the keyboard completely unusable for keyboard switching of the KVM, or even entering hotkey mode (neither scroll lock nor num lock would be sent to the KVM, instead passing right through to the computer). Uninstalling Synapse didn't help; I had to manually hunt down and install the "legacy" pre-Synapse drivers for the BlackWidow keyboard before I could get the keyboard to start sending events properly to the KVM. I'm not sure this option would even be available for newer Razer keyboards (mine's an ancient 2013 model), so beware installing Synapse if you intend on using keyboard switching. Now that I've gotten things stabilized, the system is very solid. The PC did lose connection to the mouse once, which happened on other KVMs occasionally; I'm not sure if this is down to running it through the Razer's port, Windows flakiness, using a KVM, or a combination of these. Use on the Mac has been trouble-free. I'll follow up this review if I run into any problems down the road, but so far I'm impressed with the unit and can definitely recommend it.
