    FAQ

    • The switch must receive video signals on three HDMI inputs per PC for triple monitor output.
    • Audio is transtted via HDMI connection. HDMI or DisplayPort 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 3.0 ports. 3 USB 3.0 (including 1 USB C), 2 of which are able to charge.
    • 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).

    COMPATIBILITY INFORMATION

    • 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 3.0 port as a workaround if this software is desired. The USB 3.0 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.

    Overall solid, a few quirks to be aware of

    Overall, this KVM is spot on in providing what is ultimately the only thing that matters: the ability to switch 3 monitors between up to 4 computers. The setup is easy, no drivers need loading, and the switching is reasonably fast. The EDID emulation (which is one of the main reasons I went with this model) works as expected and I've not had a hiccup with application or workspace resizing when switching between multiple Linux (Fedora specifically) systems.

    Build quality seems top notch as well; unit feels solid and doesn't make me worry about accidentally knocking it around. Charging ports on the front are a nice touch. I haven't tested the audio passthru as I only use a headset which connects via a USB dongle that I connect to a hub attached to the USB3 port on the back (and this works as expected when switching between ports).

    There are a few things however holding it back from being 5 stars:

    - I use a wireless keyboard (specifically, Logitech G915 - not sure if that matters), and the dedicated keyboard/mouse ports seem to have issues with that. Occasionally a key press won't be passed to the currently active computer. This is completely isolated to the USB 2.0 K/M ports, as using the USB3 port (or a hub attached to it) resolves this issue. However, that means that the keystrokes to switch to a different computer don't work.

    - I was also not able to use the keystroke controls anyways when the receiver dongle for my keyboard was in the K/M port. I'm not sure why, but I also have the unit directly in front of me so I'm not bothered by it.

    - The integrated switch is only 100Mbps, which makes it functionally useless for today's networks. This isn't a huge deal, but it is notable. Either put in a gigabit controller, or drop this feature entirely (or add another USB3 port in its place even).

    - The power cable is INCREDIBLY short. If there isn't an outlet within a couple feet of the unit, you won't be able to do very much cable management with the power cable.

    - The included HDMI cables are also fairly short. This may not be an issue if you have all the computers racked or right next to each other, but even then I think for 4 computers side-by-side these would be limiting due to their length.

    All that said, I'm happy with the purchase, especially since this is one of the VERY few KVMs on the market that are triple monitor with EDID emulation. I just wish there was a triple DisplayPort w/ EDID variant.

    So much more than a KVM

    The TESmart 3 HDMI Monitor, 4 Computer KVM (with EDID) comes well packed in an unassuming brown box. But in that box is an awesomely powerful KVM display switch combo capable of mixing your machines, and screens, as needed. All while bouncing your mouse and keyboard around to different devices.

    Literally a huge quality of life improvement for several members of the team. We've been running dual and triple monitor setups from back when you had to buy specialized cards and cables. These days, Im rocking a 43 with a 32 monitor on each side, displaying 2 computers and 2 laptops: Work, and play!

    Until I found this switch, I used multiple KVM/HDMI switches/and odd docking station combos Whatever I could find that didnt cost thousands of dollars. And if you arent familiar with EDID emulators, do the research (or keep reading).
    I had to constantly deal with my machines forgetting they had a great monitor layout and apps placed exactly where I wanted. When I switched using a normal KVM it would cause my open windows and icons to lose their place. Have you ever seen 14 windows on a 4k display all stacked into the upper left corner tiny and annoying like? Most likely your monitor got disconnected or went to sleep on you. Or you had a KVM that swapped the monitors over to the 2nd PC and the 1st thought it had no monitors, so Windows defaulted to something like a 640x480 resolution driver.

    EDID (Extended Display Identification) fixes this! Its incredible.

    Enter the TESmart KVM. It was like it was custom made for me. Suddenly all of my computers can be swapped to the monitors with a double scroll tap then number. The machines have no idea theyve been swapped (other than the USBs moving) and all of my apps stay where they should be. You can also use the buttons on front, a remote (included) or the RS232 port to manage the configuration on the fly. In the video attached I demonstrate the keyboard controls and then show how the front buttons and display work. If you dont mount it under your desk, it presents nicely on your desk or under your monitor if you have room.

    But wait, there s more! This TESmart enables you to SELECTIVELY swap out any monitor to the other machine. You can then, with a triple click of the alt key, control that machine. At first, I was like thats an interesting gimmick But in my day to day workflow I use it all the time. It allows me to pop one monitor over to a gaming box (during lunchtime of course) or to do research or banking, etc on a personal machine rather than my work laptop.

    USB devices can also be brought along. I only have my mouse/keyboard setup that way, but theres no specific limitation. The review unit we received has a USB 2.0 hub (keep reading!)

    There is remote (with included IR extender) but I personally never use it. Much faster to swap by keyboard. In a machine room environment, I can see where that would be very useful.

    It comes with a NICE full set of cables including USB connections. Please note this is all HDMI. There is a DP version from TESmart that doesnt have EDID.

    One of the pics I show mounted under a shelf in the server room with the rack ears attached.

    This IS the droid you are looking for!
    EDID for the win
    This KVM rocks!
    Pricey but worth its weight in gold

    PS: The newest version of this (Same model/page on Amazon) has USB-C, a network port to ensure connectivity and improved L/R audio. If you ordered one from Amazon as of April 2023 and it doesnt have USB-C contact the support team for options on replacing.

    An incredible workhorse with fantastic support and track record. Do yourself a solid and consider upgrading to a great solution.

    This works exactly as expected. I do do not understand why any negative reviews. IF you understand YOUR connectivity and YOUR objective, You will NOT have any issues. About 1.5 hrs completely to setup. I have 3 monitors, ONE Keyboard and Mouse, 2 laptops (work, personal), Web CAM, Xbox, ANNNDDD Fold 3 DEX (ONLY on one monitor so far). With the Fold I need to figure out how to do 4 outputs...lol. But beside my OWN device short comings, This KVM is PERFECT...if it is within your budget. But keep in mind the price comparably is cheaper then any other solution....HOT Keys is spot on! OH did I mention it comes with ALL the CABLES you NEED for SETUP!! Yeah! YOU may need to purchase some adaptors...AGAIN depending on YOUR devices connectivity. Delivery A+... in 2 days flat! Have not tried or needed tech support so you be the judge on that. :-) Other then that...ENJOY!

    Expensive, but works like a champ!

    I bought a new 4k large monitor for my home setup, adding to the two 27" monitors I already had. There aren't many options out there for multi-monitor KVM's and going from dual to triple narrows the field a great deal more. Another issue to be aware of is the resolution the KVM will support. I have a dual port and figured I would just use that and use the monitor's input selector for one of the side monitors. What I discovered is the dual port KVM would not handle the resolution of my 4k monitor.

    I saw that the Tesmart supported 4k up to 60Hz, which is fine for what I'm doing. Once you get the profiles set and assign the right "main monitor" on your PC, it's a simple click of the button to switch all three from one PC to the next.

    And...I love the fact that I can have up to four PC's with dual monitors using this configuration!!

    Love it, would highly recommend!
