    • Efficiently manage 4 PCs with a set of keyboard, mouse, and dual 4K60Hz displays.
    • By connecting two KVM switches HKS0802A1U(-SE) in parallel using the supplied DCCI cable, you get a 4 PC to 4 monitor KVM switch solution.
    • 2 Operating Modes: Mode 1 for extended desktop and Mode 2 for split desktop (each computer displays on 1 monitor simultaneously).
    • 4 ways to switch inputs: keyboard hotkeys, front push buttons, remote control, or RS232 control.
    • K&M pass-through for compatibility with various keyboard types: wired, wireless, mechanical, and gaming.
    • Easy plug & play setup with no drivers required.
    • Compatible with Windows, Mac, and Linux, ideal for home, office, or education scenarios.
    • The KVM switch comes with 4 x 1.5m HDMI/USB combo cables and 4 x 1.5m HDMI cables. We ensure that all 4 of your computers are connected to the KVM. Typically, monitors come with their own cables. If you need additional cables, we also have high-quality cables for you to choose from.
    • Note 1: the difference between HKS0802A1U(-SE) and PKS0802A10 is only the port, that is, all ports of HKS0802A1U(-SE) are HDMI, and all ports of PKS0802A10 are DP.
    • Note 2: due to technological reasons, all switching functions for dual monitors can only work if both graphics cables are connected to each computer.


    • Assignable hotkey triggers from Scroll Lock to Right-CTRL.
    • USB sharing for printers, jump drives, USB headsets, and webcams for teleconferencing.
    • Supports automatic switching to monitor computers at a specified time interval.

    • With high-quality cables, this KVM switch also supports QHD 2560*1440@120Hz per monitor. This requires HDMI out on the computer and HDMI 2.0 in the monitor, which many QHD monitors do not have. To do this, test 2560x1440 with the frequency directly (without a switch) from the HDMI out of the computer to the HDMI of the monitor.
    • With HDCP 2.2 support, you can not only connect PCs and laptops(possibly via docking stations) but also game consoles, etc.
    • EDID emulation to prevent resolution and icon rearrangement.
    • HDR10 and Dolby Vision support.
    • No delay, zero latency keyboard, and mouse switching.
    • On/off switch on the front.

    • We provide Free Express (UPS/USPS/DHL ) for US shipping orders.


    • TESmart KVM switch comes with a 1-year warranty from the date of purchase. We offer a registration extension warranty program, register to extend the warranty to 3 years.
    • The warranty covers any defects in materials or workmanship under normal use. We reserve the right to replace any defective product under warranty (No Repairs, Only Exchanges).


    • The switch must receive video signals on both HDMI inputs per PC for dual monitor output.
    • Audio is transmitted via HDMI connection. An HDMI monitor is required for audio.
    • Hotkeys are triggered via a keyboard plugged into the dedicated mouse or keyboard ports.
    • Emulation programming is locked and cannot be removed from mouse & keyboard ports.
    • Dedicated mouse & keyboard ports should not be used for other types of USB devices.
    • Use a powered USB hub to expand the number of USB 2.0 ports.
    • If the wireless mouse/ keyboard is “jumpy”, use a USB extender to reduce the distance from the receiver.
    • Please install 2 AAA batteries before using the remote control (battery not included).


    • Dedicated mouse & keyboard ports have emulation programming. Second-generation chipsets have “Passthrough Mode” to send special characters such as multimedia keys (play, pause, volume up/down, etc), which greatly improves keyboard compatibility.
    • Keyboard software such as Logitech Options, DAS Q, Corsair iCUE, etc conflicts with the emulation programming and limits the ability to use dedicated macro keys. We recommend using the KVM’s USB 2.0 port as a workaround if this software is desired. The USB 2.0 port does not have emulation programming and therefore the KVM will not recognize hotkey switching commands. Please use a powered USB hub to expand USB connectivity, if needed.

    I'll NEVER Have to Leave my Desk AGAIN! 😂 - TESmart KVM HKS0802A1U

    With this beauty from TESMART, you can connect up to 4 devices and 2 monitors, with resolution locking and support for up to 4k60. The KVM also shares 2 USB 2.0 ports, making it easy to switch between devices without having to reconnect peripherals.

    Not only is this KVM great for gaming, but it can also be used to switch between PCs with different OSs, stream with fast switching between consoles, and more!

    Device works fine. My only real criticism is that that for the 4x2 configuration, the computers you connect are all required to have 2 hdmi ports. The device will not work correctly if you connect a computer that only has one external hdmi port (Please note, that you can easily get a display port to hdmi adapter, so if you have a computer with a display port and and hdmi port, that'll work if you get a display port to hdmi adapter). The requirement for two external hdmi ports is not obvious until you read the setup manual. It's usually not too hard to add a second hdmi port to a computer with only one external hdmi port but that's something you need to be aware of. I not sure what the electronic issue is that requires you to have all connected computer to physically have two external hdmi ports. Could there be an hdmi termination plug available for the case when you only want to use one display for an computer.

    I'm giving it a 4 star rating instead of 5 stars, because of that issue.

    It takes several seconds to switch between computers or after sleep . I think that time delay is probably do to the computers OS an not the kvm itself.

    Currently I have two Windows laptop and I'm planning to add a mini mac.

    I run 2 devices at home, one is a linux desktop with a Windows VM for gaming (GPU passthrough), a Macbook pro 2019 and a Macboook Air M2, the laptops are connected to a USB dock and it works well with dual display (yes, even for Mabook Air M2 using InstantView). It takes around 3 seconds to switch from one device to another and as advertised due EDID emulation the devices keep their windows in place as the monitors were still connected. The keyboard and and mouse feels instant as soon as you're able to see the screen. I have two asus monitors 1440p and so far, on the HDMI cable I succesfully were able to run it at 144Hz. I also tested with two active DisplayPort to HDMI cables and they work without issues (new computers usually comes with just a single HDMI port) and also tested with USB-C to HDMI cable and worked very well. Currently

    I have a wireless dongle for a Razer Pro Type and a directly connected Razer Pro click, I used these before the KVM as they allow you to switch between devices but the mouse ended with faulty bluetooth and this KVM solved all the inconveniences of changing inputs on every monitor and switching bluetooth mode on each device, It feels amazing and truly improves multitasking being able to easily switch everything with a single button. Even in passthrough mode, it's easier to switch between devices with key shortcuts. The operating systems properly detects they're the advertised devices and so far, the multimedia devices and the additonal mouse buttons work well.

    I used a couple of times split displays and works as advertised, no much to say about this, I would say it depends more on how you handle your devices if you can take advantage of this feature or not. The frontal USB port is connected only to the device you are attached so be careful when connecting storage devices as they are disconnected from one device to another when switching. It works well so I think it's useful to have an extra usb port that directly attach to every other device.

    The device feels sturdy and doesn't take too much space, its like the size of a tenless keyboard but taller, and can be easily accommodated below a monitor if you have a mount. Not exactly an apple looking device but definitely a lot better than a cheap plastic product. It comes with all the cables needed for connecting your devices and this helps you to make this work out of the box very easy.

    The cables are great and feels they're good in quality, however, I have my devices at different distances and a couple of them feels a bit short in order to do some cable management (for example passing the cables behind my desktop or placing my laptops far from the KVM.

    Overall, for those who seek doing VM without the complexity of software switching them, or adding physical devices this works great. I would say overall if you have pletora of devices going with the HDMI version is better as it's easier to find adapters for Apple devices that use hdmi and it's easier to find HDMI on TV and consoles.

    Great HDMI KVM with EDID & high refresh support

    This KVM is well worth the money. Now it doesn't have USB 3 so I can't say its the perfect KVM for me, however other than that I have nothing bad to say about it.

    I run 3 computers at home, one windows gaming rig, one linux server, and one Mac OS laptop from work through a USB C dock. All three have no issues with this KVM which is awesome. I used to have dual monitor DVI setup for them, until I upgraded my monitors. I needed to find a new KVM to deal with the HDMI (or Display Port) connections on the new monitors without a bunch of converters.

    I started with a cheaper 4 port dual HDMI KVM, however I grew real tired of there being no EDID emulation. That led me to this model. This is a really great KVM. It supports my new 2K 144hz monitors with aplomb, has no issues with my MS Natural 4000 keyboard (in terms of extra functions) and switches fairly quickly. The EDID emulation means my screens don't revert to single displays when not the focused machine. All the good things I missed on the cheaper one I picked up.

    There are a few things I miss from the DVI one I had. For one this one does not let you switch the USB hub independently (at least that I can find) which is nice some times if I want to list to a meeting on my work computer but check something on my server (I use a USB Audio card plugged into the USB 2 hub on the KVM). The other thing I miss is with the old KVM I was able to reset the USB switch via keyboard shortcuts. This makes it easy if something doesn't catch properly after the switch (looking at you again USB sound)

    Overall I think this model does the right things and is worth the money, as to get the perfect KVM (at least in my opinion) it would be at least twice the price and I personally don't have that kind of budget.

    Dual Monitor KVM Switch

    This dual monitor kvm switch works as advertised. I’m running a Mac Mini personal computer, HP laptop work computer and HP desktop side business computer though it into two external monitors, printer and and webcam & it’s all works well. If you want to run 3 or 4 different computers into the same two monitors, printer and webcam, this will do well

    Works well

    Works exactly as expected. You can display one computer per screen and the keyboard and mouse smoothly shifts between them.

    Bit expensive but worth it if you need it. The only difficult thing to work with is the way you select which monitor displays which computer. It is simple once you practice pressing the display button and desired input button quickly.

    I use it for work, so it has a server, and three laptops connected. Basic Logitech mouse/keyboard combo. Simple 1080 hp monitors. I even use some hdmi to dp and hdmi to usb c converters, works great.
