    • Compatibility info + Great to mount under your desk.
Size: for 4 PCs 1 monitor with mounting holes Color: Black
This KVM seems like a good value for money. Here are some details I thought I’d share since I wasn’t sure about them the moment I bought it and not many people mention them: - Supports EDID emulation. That is, when you’re switched to one device the rest of the devices think the display is still attached to them, so they behave nicely, instead of shifting windows around as if you unplugged the external monitor. - HDCP is supported according to the nVidia Control Panel. - USB is 2.0. That’s okay. I don’t think there are many uses for USB 3.0 on a KVM. I don’t think storage devices should be used on a KVM, and you don’t need to switch a network adapter between computers, you just connect all the computers to the network with a normal ethernet switch. - The included cables have the HDMI and USB parts stuck together. That is nice because it keeps everything tidy. You can also separate the cables as much as you need. Now I want to buy the optional extra 2 cables. - LEDs are blue. Very bright, you know the type... - Runs very cool. Uses less than 5W. - The device is a little ugly but hey, there’s a desktop version also, a little prettier (comes in red, black or blue). I’m mounting it under the desk so I needed this version with the screw holes. - The “Online” LEDs detect when the USB cable from the computer to the KVM is connected, not the display cable. - Power brick doesn’t take additional space if your power strip is aligned the traditional way (like this = = = = = = ), big plus. - Remote doesn’t have a lot of range, but you never have to press a button twice. The thing I dislike about remotes powered by coin cells is that you seem to need to press the buttons multiple times for them to do something. This one has nicer quality buttons so whenever the remote is in range (is not as powerful as a TV’s) it’s going to work reliably. If the KVM is bolted under your desk, you’re going to have to point the remote under your desk. - If you ever run into issues with black/green screens after switching back and forth to one device, try using a different output or a different converter combination (see details below). - I have no idea what the M and P buttons do on the remote. —- USB COMPATIBILITY —- - Tested with Logitech Unifying Receiver that is connected wirelessly to a Logitech K850 keyboard and a Logitech M720 mouse - Hot keys work with this setup (you can press Scroll Lock twice then press PgUp/PgDown or 1, 2, 3, or 4 to select inputs). - Hot keys work only on the top row of numbers, not with the number pad. I think this applies to all keyboards. - The Logitech software (Logitech Options) will not detect your mouse and keyboard as Logitech if you are plugged into the KVM's mouse and keyboard USB ports. This is because the KVM connects directly to them and emulates a virtual mouse and keyboard and presents that to the computer. If you want Logitech Options or similar software to work, you have to plug the mouse into the third USB port, the one for devices. Hot keys don't work on that third port, though. —- VIDEO COMPATIBILITY —- - I found a compatibility issue using a Dell WD19 docking station and Apple devices. Both of these have a workaround, please read below. - 2020 M1 MacBook Air -> Dell WD19 docking station HDMI output -> TE Smart 4x1 KVM -> LG Ultrafine 25UM58 (resolution 2560x1080) —->>> NOT WORKING, display goes black or dark green after switching from this source to other source and back to this source. You have to disconnect and reconnect again. - 2020 iPad Pro 12.9” -> Dell WD19 docking station HDMI output -> TE Smart 4x1 KVM -> LG Ultrafine 25UM58 (resolution 2560x1080) —->>> NOT WORKING, display goes black or dark green after switching from this source to other source and back to this source. You have to disconnect and reconnect again. -This incompatibility CAN BE SOLVED if you use the Dell WD19’s other outputs. I tested this chain and it works: - 2020 iPad Pro 12.9” -> Dell WD19 docking station USB-C DP output -> Apple USB-C Digital AV Multiport Adapter ->TE Smart 4x1 KVM -> LG Ultrafine 25UM58 —->>> WORKS - It should work on the M1 MacBook also but I didn’t test; the computer was borrowed. - Other adapters could work too. I think that the WD19 has an internal HDMI adapter that doesn’t like the KVM for some reason. There seems to be a timing/sync issue because the display shows multi-color noise or static then goes black. Anyway, this setup is for one display output so you don’t lose anything by using an adapter on the other port. I tested these and they worked and also worked after switching back and forth: - Dell Latitude 5300 -> Dell WD19 docking station HDMI output -> TE Smart 4x1 KVM -> LG Ultrafine 25UM58 - PC with RTX 2060 native HDMI output -> TE Smart 4x1KVM -> LG Ultrafine 25UM58 - PC with CableCreations DisplayLink USB to HDMI adapter -> TE Smart 4x1KVM -> LG Ultrafine 25UM58 - 2020 M1 MacBook Air -> Apple USB-C Digital AV Multiport Adapter -> TE Smart 4x1KVM -> LG Ultrafine 25UM58 - 2020 iPad Pro 12.9” -> Apple USB-C Digital AV Multiport Adapter ->TE Smart 4x1 KVM -> LG Ultrafine 25UM58 - 2014 MacBook Air -> generic Mini DisplayPort to HDMI adapter -> TE Smart 4x1 KVM -> LG Ultrafine 25UM58 - 2020 M1 Mac Mini via native HDMI -> TE Smart 4x1 KVM -> LG Ultrafine 25UM58 --- AUDIO --- The 3.5mm audio output works this way: it intercepts the signal from the selected HDMI input and it outputs the oudio for that selected input. I'm not sure if the monitor also receives the signal. The audio quality is better than my monitor and better than my Raspberry Pi 3B. The output doesn't have any hiss or noise, which is great. I don't normally expect these types of products to have good sound. Note that Apple devices can't adjust HDMI volume for some reason. It's Apple's fault though. Very frustrating. I will be adding more devices as I test them (Raspberry Pi 3B, Raspberry Pi 1B, generic DisplayPort adapter on the WD19 dock instead of Apple USB C adapter, etc.). I can’t test HDR support. To be honest I’m glad I found a workaround for the Apple + WD19 incompatibility, because this KVM is very very nice and that would have been a dealbreaker. I don’t think it’s the KVM’s fault given it worked with everything else so I’m giving it 5 stars. ... show more

    • Works well with a Windows tweak

Review Image by Amazon Customer Amazon Customer
PROS: It worked out of the box on all four ports CONS: Windows 11 Computer lost USB Keyboard/Mouse everytime sleep was activated. There is a fix, but had to find it. Nothing on manufacturer website other than try the USB dedicated port (reason I deducted a start. So, this is my second TESMart KVM. The first one lost USB port 4 in the first 6 months. Lived well on 3 ports for about 2.5 years, then all of a sudden issues on port 2 so I started my search again for a KVM. Other than failed ports, the old one was great. So after a lot research, I decided on this updated model (mainly due to cost), and bought the warranty in case the ports start crapping out again. Install was nothing special, but everytime my win 11 computer would go to sleep mode, I would completely lose the keyboard and mouse functions. Rebooting the KVM seem to fix it, and it occured on all ports everytime. Could find nothing on the problem on TESMarts web portal. Looking elsewhere I found that this was common generic issue in KVMs with EDID emulation due to the USB ports being powered down at sleep. Fix is to turn off sleep (either on the computer or USB ports), I tried isolating the USB port power down using the windows power settings and it did not work. So I checked the Device Manager USB controller and settings, and for whatever reason the settings did not propogate from the power app to the actual controllers. So here is my fix: right click on EACH USB hub, select properties, select power options, and disabled the sleep mode (uncheck allow the computer to turn off..) This has fixed the problem and happy to report that the KVM is working flawlessly. I suspect you could isolate the actual port/hub you are on, but for me I don't care about penny or so of power it might save a year. I will update this post if I get a port failure on the KVM, and update on the warranty execution if this occurs. ... show more

    • A solid, decently priced option with small hiccups (Don't use the Keyboard USB Port).
Size: for 2 computers 1 monitor Color: Black
I purchased a switch to toggle between a tablet at my work desk and my work PC. Overall, the physical unit's quite nice, and the power and device selection switches are easy to access. I also appreciate that it comes with the necessary cables for both devices The feedback is responsive (for the most part, but we'll get to that), and swapping devices is almost instant in terms of input. The monitor swapping takes a second or two longer, but again, nothing intolerable or even annoying. The main issue I've had is that it appears that at times, the keyboard/mouse input will drop an input or become stuck here or there (such as a down keypress becoming stuck and entering that same key several times until I press it once more). I'm not the best typist, so I originally simply chalked it up to mis-input on my part, but the sheer number of times I noticed this caused me to begin doubting. I wondered if it may have been a keyboard issue, so I swapped the membrane keyboard I had out with a mechanical I had on hand that I usually use for another PC, as cleaning the keyboard also had no effect. Unfortunately, the problem persisted. After digging through several posts regarding dropped inputs via KVM, I started searching specifically for posts including "TESmart". I stumbled upon one that suggested that I try moving the keyboard to the USB 2.0 port on the back, rather than the dedicated keyboard slot. So far, it seems much more stable, which is great. This does unfortunately disable the usage of the built-in keyboard shortcuts, but considering the switch is right on my desk right behind my keyboard, it's not an issue for me. This is something I would definitely try to keep in mind if you do purchase it; this does mean you either need to use the remote, or keep the unit in arm's reach, but otherwise, it works pretty well and at a decent price for what it does. ... show more
