  • KVM,4-Port,Dport,Audio,USB 3.0 Hub

    • Product Description

    The desktop B004-DPUA4-K 4-Port DisplayPort KVM Switch lets you access, control, boot and reboot four DisplayPort computers using one DisplayPort monitor, USB keyboard and USB mouse. Switching among DisplayPort computers is quick and simple using keyboard hotkeys or buttons on the unit.

    You can also plug microphones and speakers into the 3.5 mm mini-stereo jacks, and the two-port USB 3.0 SuperSpeed hub allows you to connect peripherals, such as a webcam, flash drive, printer or scanner, and share them among computers. Because the audio and USB 3.0 hub ports can be accessed independently, you can, for instance, use a printer connected to the hub to print data from one computer while also listening to music from another computer.

    All necessary cables are included. The B004-DPUA4-K supports digital video resolutions up to 2560 x 1600 (including 1080p), 2-channel stereo audio and data transfer rates up to 5 Gbps. The built-in DDC emulator sends the console monitor’s EDID information to all connected computers to ensure top video quality and prevent any delay or change in video resolution when switching computers.

    The B004-DPUA4-K is easy to set up with no software to install and supports Windows, Mac, Linux and Sun. The USB 3.0 hub is backward-compatible with USB 2.0 and USB 1.1 devices.

    5.0 out of 5 stars but now it works great and is everything that I hoped for
    Reviewed in the United States on April 18, 2017
    Style: 2-Port DP 1.2Verified Purchase
    Took a little finessing to get it setup correctly, but now it works great and is everything that I hoped for! Was a little worried that it might have issues working with my 1440p/144Hz GSync monitor but so far it has been great and GSync works without a hitch. I use it with both a desktop PC and Macbook pro connected.

    The only issues I had with the device were during the initial setup phase. At first my mouse (a Razer Taipan) felt weird and floaty/laggy when connected to the KVM and USB devices (like memory sticks) plugged into the side of my 'Das Keyboard' would not register or work. Upon further investigation I found out that the mouse was being recognized by Windows as a 'generic' pointing device and not a Razor Taipan - therefore it was not using the correct Razer drivers; something similar appeared to be happening for the keyboard also.

    Eventually, after reading the manual I found out that by default the hub does 'mouse emulation' where it tries to virtualize connected mice into more generic (presumably compatible) devices and it also does a similar thing for Keyboards where it translates keystrokes etc. for different keyboard types. Turning off both mouse and keyboard emulation in the hub settings allows the USB devices to pass straight through and be used directly - solving both these problems.

    Was considering returning the hub if the mouse lag had not been solvable so if you're having issues be sure to check the settings first and turn off both keyboard and mouse emulation! My one piece of advice to the manufacturers for future products would be to turn off these things by default since most people probably just want to use their USB devices directly and not go through emulation/virtualization layers.

    4.0 out of 5 stars Overall, the best you can expect at this price point in early 2017. All my issues solved by a powered USB hub.
    Reviewed in the United States on March 7, 2017
    Style: 2-PortVerified Purchase
    I had written a mostly problem-free review earlier this week-- before embarking on a troubleshooting nightmare... I still give the device 4 stars, though. My setup includes a 4K LG monitor, a 2-year-old Dell Latitude (Windows 7) on dock w/ displayport, a brand new Dell Precision (Windows 10) without dock w/ mini displayport, a Logitech Marble Mouse, a daskeyboard w/ dual USB, and a 10-year-old Targus keypad (w/ num lock and arrows).

    The KVM's "console" connections include displayport, a dedicated "keyboard" input, a dedicated "mouse" input, and a 2-port USB 3.0 hub. Each of the computers connects via one displayport and one USB 3.0 cable. All necessary cables are included and of high quality with beefy shielding on the displayport cables.

    Now, here's where it gets strange. Ideally, the keyboard plugs into the "keyboard" connector and the mouse plugs into the "mouse" connector. This mounts these devices to a manager inside of the KVM which keeps them up at all times with a fake-out emulation sent to the currently inactive computer(s). That way, neither the keyboard nor the mouse fall asleep unable to wake either computer from sleep. This odd emulation system of course negates the user's ability to configure power management of the mouse. This setup works perfectly, assuming you do not bump your desk and jostle the mouse.

    Here's my workaround: I want the keyboard to connect via the "keyboard" input and yet I want the mouse to operate via a hub input (to allow power management). The KVM "console" hub only has two USB inputs. My numpad (USB 1.1?) cannot apparently connect via yet another hub due to it having a hub itself. So, the numpad must take up one on the KVM's USB ports. I purchased a powered hub and plugged my mouse and keyboard hub into it. I'm not sure why the keyboard hub seems to require constant power for the keyboard to stay active, but connecting via the powered hub without power seems to make the computers forget the devices every time the KVM switches. Keeping this plugged into power seems to keep the mouse active as well so it doesn't take as long to reconnect. So far so good. To be clear, the included (2) USB ports do seem to adequately power things up. It's the connecting through an unpowered hub which seems to drop connections. Powering the hub solved everything.

    On displayport: The displayport connection works fine with my older laptop via dock and KVM @2k 60 Hz. However, when I try connecting my new laptop via mini displayport with the same length of cables, 60 Hz just does not work. It flashes for a fraction of a second and tries but reverts back to 30 Hz. It works with a direct connection to the monitor but not via KVM. I'm hoping that once I receive my dock, the performance will be equal to that of the older computer. I don't really understand why this would be an issue, but it is for me.

    One last note. The capacitive touch buttons on the unit are bright white. Not only is there a red light to indicate side, but there is also a giant white light which flashes incessantly if anything is disconnected. If the mouse or keyboard is not connected to their dedicated ports, it flashes. If the video or USB connection is missing due to the computer being asleep, it flashes. This is highly annoying in a bedroom. I ended up neatly covering the buttons with electric tape. They still sense just as well through the tape.

    3.0 out of 5 stars Functional product with flaws.
    Reviewed in the United States on January 12, 2019
    Style: 2-PortVerified Purchase
    I am using the B004-DPUA2-K to switch between my Linux PC and my Windows PC. Both are connected to my LG Ultrawide monitor (2560x1080). I was afraid I wouldn't get proper ultrawide resolution, but video output actually works fine.

    So far I have found two rather annoying issues. I'll start with the worst: the KVM's mouse port. I have tried two different mice: a wireless Logitech Anywhere MX which uses Logitech's unified USB dongle, and a wired Steelseries Sensei Raw. With both mice, connectivity is extremely sporadic. The moment I think it's all working great, suddenly either Windows or Linux will stop detecting it. I tried using the separate USB 3.0 port, but then I kept having connection issues with Windows. For some reason Linux didn't have issues. I rebooted several times, unplugged and plugged the power to the KVM, and the issue persisted. I also tried connecting my mouse to a small USB hub, which was then connected to the KVM USB 3.0 port, and the issue persisted. I suspect this is some sort of firmware bug in the KVM. After a few hours I got fed up and pulled out my A/B USB switch solely for my mouse. It's janky because now I have two buttons to push to switch between PCs, but at least I don't have to deal with a mouse that sometimes doesn't work.

    Second issue: its sound output. You must connect each PC to a line-in port on the KVM. Then you connect the KVM's line out port to your sound equipment. When sound is routed through this KVM, there is noticeable distortion when I listen to music. It's not so awful that I would suspect a manufacturing defect, but when I use my headphones and do an A-B test between KVM and no KVM, the distortion is definitely there.

    The included manual is only a couple pages, but it is fairly adequate. It has a list of hotkeys to send commands from your keyboard to the KVM unit. The first thing I did was disable the sound which by default BEEPs every time you toggle between PCs. I greatly appreciate the option to disable the beep because I found it obnoxious.

    The unit is housed in a steel box, and overall its size is convenient (1.8" high, 6.5" wide, 3.5" depth). Despite its compact size it has a little bit of heft, which is good for physical stability. Whether it will actually stand the test of time obviously remains to be seen. The 1-2 toggle buttons are touch buttons. The touch buttons themselves are over a white LED, and above each button is a red LED. The LED lights are a little too bright for my taste, so I will probably put tape over them to make them dimmer.

    In conclusion, this unit "sort of" does its job. Video works. Keyboard works. It switches between two PCs with reasonable lag time (~3 seconds). But it isn't without issues. My mouse won't work properly. The KVM introduces sound distortion. For its flaws, I feel confident in a rating of 3 stars.
