Fantastic It switches 2560*1440 w/o issues. Able to share a printer/usb drives between computers.

Wow. Everything worked without any hassle and it works quite nicely (after 250 days of usage these statements still hold true) Two Laptops, One Keyboard, One Mouse, One 2560x1440 Monitor, One Usb hub Laptop 1, Win 10 pro, has an hdmi output of 2560x1440 (laptop display 1920x1080, Intel HD Graphics 4600) Laptop 2, Win 10 home, has an hdmi output of 2560x1440 (laptop display 1366x768, Intel HD Graphics 620) Anker USB hub plugged into the KVM Usb 2.0 port which allows me to share a usb printer and 3 backup usb hard drives between the 2 computers. Wired Microsoft Natural Ergonomic 4000 keyboard into KVM keyboard port Logitech Wireless mouse M325 plugged into KVM mouse port Keyboard switching works fine (ScrLk, ScrLk, 1) or (ScrLk, ScrLk, 2) to switch between computers. Mouse switching works fine (move mouse pointer to left/right edge of screen twice) to switch between computers To enable Mouse switching ScrLk, ScrLk, F12 to enable, sensitivity led comes on when enabled Mouse switching sensitivity is adjusted with sunken front button (1 flash = 500ms, 2=750ms, 3=1000ms, 4=1250ms, 5=1500ms)

Works as expected

Using it to switch between four PCs connected to a 3440x1440 monitor. Works as advertised. You can switch using hotkeys or a small remote. Every switch takes about 3 seconds. A couple of notes: * It does not come with USB cables; you will need to provide your own USB-B male (old-style, "square plug") to USB-A male (large flat plug) cables for each PC. * It does support 3440x1440 @ 60 fps RGB 4:4:4. If you have a hi-res monitor, you definitely don't want to settle for other KVM switches if they only offer 30 fps, even if you're not gaming. (One of my systems is connected through a third-party DP->HDMI adapter, which is only capable of 30 fps, and it is fairly unpleasant, the mouse cursor is too jerky.)

Buy it quick before they put the price up!

if you need a KVM that runs 4K @ 60hz buy one of these before they realize they got their pricing wrong! I have 2 PC's and Mac that share a monitor. I just upgraded it to a wide screen 4k screen which no longer worked with my old Aten 1644 KVM switch. So I thought I;d go buy another Aten KVM (the 1924), $400 later i'm fighting with DisplayPort issues randomly resetting the monitor to 30hz and point blank refusing to work with any HDMI -> DP converter for one of the PCs. So I figured I'd try and do everything over HDMI. Bought this,unpacked it, plugged everything in and it's been running flawlessly since. It's awesome. Some notes: you need to buy cables, it doesn't come with them, get some good quality HDMI 2.0 cables if you want 4k @ 60hz. I have a Microsoft Sculpt comfort keyboard and mouse combo with a single USB receiver, it works great, I can change the PC focus using the scrlk double press. HDMI audio works without any issues. I've got a GTX 1060, GTX 1080 and an Intel Iris 640 graphics card running through it with the latest drivers, picture quality is tack sharp. It takes a couple of seconds to switch between inputs, sames a most KVMs i've ever used. It emulates the keyboard and mouse, so there's no USB connect disconnect when you switch. I can wake all my machines from sleep when i switch to them regardless of if i've moved focus since they went to sleep (this was something that never worked on my old KVM). The remote control is a neat idea but not sure why i'd use it for a PC, maybe useful if you get this for sharing your TV, it doesn't come with a battery, it's a CR2032 flat thing. It's a complete steal at this price.

Works well in my setup.

So far this thing works great. Seems well built and it’s a bit bigger than I imagined. Right now I have 3 computers hooked up through this KVM and it works flawlessly with my 2560x1440 widescreen monitor. Saved me a lot of dough and headache not having to buy more monitors and keyboards (not to mention the space required for all the extra hardware). Even grabs the audio from the hdmi! Pretty sweet. Hope it lasts for a long time.

1st UHD x 60Hz x 4:4:4 HDMI 2.0 KVM I've seen and great price.

Ordered Feb 24, promised Mar 22 - Apr 9, arrived Mar 16. I have a 3840 x 2160 x 60 Hz x 4:4:4 monitor and needed an HDMI KVM. Testing just beginning but so far both Windows 10 and OpenSuse Linux work well and the standard test image reveals it delivers. Switching takes about 3 seconds. I'm no gamer so standard KB/Mouse is all I care about. I also don't care about HDR so that's not tested either. USB is only 2.0 but my Epson V600 scanner switches and works well. Be sure you use 18 GHz cables. UPDATE: it's been about a month now and still working just fine. This KVM will drive a Ruipro 30-meter active (fiber) HDMI cable with no issues. SImilarly with Monoprice baluns over cat 6 for keyboard/mouse. It's really only the keyboard you have to worry about to preserve hot-key switching. I expect any mouse can go on a hub at the end of the switched USB. Now looking for a good active USB cable for the scanner as the passive one just won't work (no real surprise with a cable that long). The connectors for the cables seem a little flimsy so I'd be real gentle with them

Excellent KVM HDMI+USB switch

This is a 5 star product despite a few problems in the packaging, shipping, and documentation. First, here are the problems: 1. The remote didn't come with a battery 2. There are only 2 cables for the 4 port switch, and they are too short. 3. The documentation lacks detail: e.g. the batter type (CR2025) is not documented; all the keys on the remote are not defined, etc. 4. the power cord is too short. It would be nice if the unit could be powered from USB, even if it was a dedicated USB rather than one of the 4 input ones instead of a wall-wart transformer. Those disadvantages are far outweighed by the performance and features of the switch itself. I'm using it with Fedora 28, installed on both a desktop and an IBM X220 laptop. The output monitor is a 34 inch Dell U3415W with 3440 x 1440 pixels. On the input side I'm using a Logictech wireless mouse and an IBM Model M13 trackpoint keyboard which is connected to the switch through a PS/2 mouse+keyboard to USB converter. (Two input cables, one for the trackpoint and the other for the keyboard and one output USB cable that surfaces both devices to the KVM's USB controller.) All this works great. I don't see any artifacts or ghosting on the display when driving at full resolution from either source. The keyboard, mouse, and trackpoint all work fine and switch without any problems between systems. The keyboard and trackpoint are handled through the USB port labeled 'keyboard' on the switch, and the wireless mouse adapter is plugged into the 'mouse' port. I'm not currently using the other USB switched port. In my view, they are a little risky unless you're using them for another input device like a bar-code reader. e.g. you don't want to connect a CD-writer to them and have it disappear from the system writing to it when you switch displays... I also verified that the 3.5mm audio jack carries the audio of the currently selected HDMI port. The Scroll Lock key is the hot-key used to switch sources. Pressing Scroll Lock twice quickly in succession and then number 1,2,3 or 4 switches the display to that source. Other combinations are also available -- e.g. pressing Scroll lock twice and then "page up" switches to the next higher computer (or back to 1). Likewise for page down. Pressing Scroll Lock and then Space bar starts "autoscanning" where the display automatically cycles between "online" inputs every few seconds. You need to press scroll lock twice and then number 1 to 4 to stop autoscanning (another undocumented item). It takes two or three seconds for the Dell to display the image after you switch sources. Autoscanning only switches to ports that are 'on' as defined by those connected to the switch with a USB cable. So if you connected Roku or Chrome sticks which don't have a USB connection, they would not display automatically when scanning unless you cabled that port's USB to some source so it would see power. But you can manually switch (Scroll lock + number) to any port, regardless of its 'on' status. Of course, this may be an advantage if you really do have a Roku connected -- you probably don't want to autoscan it anyway while you're monitoring your computers from across the room. The EDID feature on the input ports means the host computers don't know that the monitor has disappeared from the configuration. Normally, with a dual-monitor configuration, switching out one monitor would cause the O/S to reorganize its windows onto the remaining monitor. That doesn't happen with this switch -- when the switch documentation mentions "fast display switching" its referring to the fact that the O/S doesn't have to reconfigure the windows -- they are already in place when you switch the display back to that source. EDID has the same affect on HDMI sound. Ordinarily, if the HDMI monitor receiving the sound leaves the configuration, Linux routes the audio to another sink. That doesn't happen with this switch in place because Linux isn't notified that the HDMI video and audio sinks have been removed. So the EDID retention can be a benefit or a detriment depending on your situation. The mouse gesture switching does work -- moving the mouse to the side of the display causes it to switch to a different display. However, this doesn't work well in a dual monitor set up -- the switch doesn't know a 2nd display is involved and switches when it should not. Fortunately, you can turn off this feature. One important point -- even though Scroll Lock is the hotkey, you can still use it for 'normal' functions. On my system, I use Scroll Lock to toggle between US and an APL keyboard map. The only difference with the switch installed is that it takes 2 seconds or so before the system sees the scroll-lock keystroke -- because the switch is waiting to see if there are two in a row -- if so, it will suppress them and not send them to the computer. What's not quite right is that the KVM passes other keystrokes to the computer before sending the single scroll lock. (It should send the single scroll lock keycode as soon as it sees a non-scroll lock key...) So if you are using scroll lock to switch keymaps like I am, you need to wait a second or two after pressing scroll lock before typing, or the computer might generate the wrong key codes. Neither this minor issue, nor the problems mentioned at the beginning of this post prevent me from giving this KVM a 5 star recommendation. Lastly, TESmart also makes 2 port, 8 port, and 16 port KVM switches. As far as I can tell, they all use the same remote and work basically the same. They also make a HDMI switch -- in the same form factor as their 2 and 4 port KVMs. Make sure you don't accidentally buy the HDMI switch instead of the KVM unless that's what you really want. The KVM version costs more.

REAL 4K KVM & can be tricked in supporting advanced keyboard/mice like corsair K95 K70

1) proper 4k DISPLAY support: AFAIK, this is the only affordable KVM switch that properly support 4k screens. unfortunately, the term 4k encompass many different flavors/lose interpretations... most KVM below $200 pretending to support 4k do not support the full HDMI 2.x protocol, 4:4:4, HDR, 60K refresh etc...This one does. BTW, AFAIK it looks like my PC thinks that it is working fine in full 4K: 4096x2160 (but on my TV I am missing some of the side... I am unclear if it is a limitation of TCL TV or the switch itself so I stick to the 3840x2160 ) 2) EDID emulation: As a proper KVM it also keep emulating a the screen of the unselected devices... this means that if when you switch from machine 1 to machine 2; machine 1 still thinks that it is still connnected to the screen and won't disable its hdmi output... in practice, that ensures that you can your windows won't be all rearranged on your attached laptop to fit your puny laptop screen or that you can still connect to machine 1 through teamviewer without getting a blank screen.... 3) single USB 2.0 port swtich In addition the the KVM includes a generic non-emulated single usb2 port. This is very useful if you need to share any arbitrary usb device without emulations (that means that when you switch from one PC to another the machine will think that you just plugged in whatever device is attached to the port and will take a few seconds to "discover it")... -> You also lose the ability to switch directly from your mouse and keyboard if you don't use the emualation... so you are stuck clicking the remote or the switch itself... This is a great feature if you use more advanced devices like tablets, mouses/keyboards with extra buttons, gaming devices with higher polling rate (the kvm keyboard emulation is limited to the 1970's 125Hz...), wireless headphones etc... Since it is limited to 1 USB 2.0 port, I am using a separate POWERED hub (which happens to be usb 3..0 but obviously backward compatible with usb 2.0)... that allows me to share with access to all keys and functions: using this old hub: (https://www.amazon.com/gp/product/B00VK9PRIU/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) 3.1) keyboard = corsair K95RGB (fully recognized with macros/extra audio keys/iCUE) 3.2) mouse = logitech G502 with all the mouse buttons 3.3) USB wireless headset = steelseries 7 Cons: AFAIK, there is no way to disable the keyboard/mouse emulations functions... note: If I had a wish list, I would l like the next generation of KVM switches to be able to: 1) include their own integrated powered hubs supporting 1 USB 2.0, 6 USB3.x, 1x USB C 2) support higher polling rate for USB keyboard/mouse (1000Hz) 3) have a much smarter emulator able to pass transparently all the codes as-is and only "trap" the usual scroll-locks combo. 4) have a button to enable/disable keyboard emulation at-will (to use during bios setup for instance)

Works with 4K

Update: You may have to use the port labeled USB 2.0 on the back if you want full capabilities from a wireless keyboard and mouse combo if using a Logitech Unifying receiver. Also, I saw where others report the remote doesn't work. Well, I too was under this impression after trying it today. The kind folks at Tesla Smart insert a plastic sheet in the battery compartment of the remote with a little tab sticking out so you think there would be a battery in the compartment and all you have to do is remove the plastic to get it going. BUZZ - WRONG! After trying the remote and it failing, I slid out the battery holder and to my surprise there was no battery to be found. I located and installed a 2025 button cell and the remote works. TESMart contacted me in response to this review and direct communications with them and tell me they plan to update their documentation concerning the battery or lack thereof. Initial Review: I had previously tried another KVM which was initially described to support 4k, but it did not. The Amazon product description was eventually adjusted to reflect this limitation. So I ended up using the KVM for only Keyboard and Mouse and a 4K signal switcher for the video. This worked, but when I saw the Prime deal for this KVM, I decided to give it a try. My systems are a Windows 10 desktop, two Linux hosts, and an OWC dock for my MacBook Pro. Hook up was very easy for me as I all I had to do was move my USB cables from the old KVM and the HDMI cables from the 4K switcher to the new KVM. I should also note that I use a Logitech Unifying USB receiver for my mouse and keyboard. The Windows 10 host was picked immediately on source 1. When I tried to go the Ubuntu 18.04 host on port 2, the monitor went to sleep when no signal was seen from the host. So, I went back to the Windows host and opened a secure shell to the Linux host and rebooted it. I then went to source 2 (Linux Host) and the video signal was detected on the KVM as the system booted. Lesson learned is it may take a reboot to get the video signal to pass through the KVM, or the safer bet, have the systems off when hooking up the KVM. I don't see any degradation of the video signal and the mouse and keyboard behavior is normal. In Windows the hotkey of Scroll Lock + Scroll Lock and number key press to select another source works fine. I haven't tried the keyboard shortcut on the Linux or Mac as I have never seen it work with those operating systems on previous KVM's I have used. So I just use the push button on the front of the KVM to go to another system when using them (or use the remote). So far I am very impressed with KVM for the money.

Works well for 3840x2160@60Hz 4:4:4

Overall is an outstanding product, and I use it to get perfect image 4:4:4 3840x2160@60Hz on my Samsung 40" TV. For 10-bit color, I can only get 30Hz, but my TV has the limitation, so I am not sure if the problem is with this unit. I saw other reviewers complain that it does not come with the cables - I used to have an Iogear KVM that came with all the cables, which is sort of nice, but on the other hand, for the price I paid for this, and the fact that you can actually buy fairly cheap the other cables, I'm pretty happy. The icing on the cake is that you can actually buy any cable size you want, mix and match them any way you like. The cables were good quality, and I paid about $40 for them, and if I have a distant computer I could accommodate it with a pair of extra long cables. As you can see in the picture I'm sharing, I'm using a couple of 1ft USB and HDMI cables for my laptop and mac mini, and using longer 6 ft cables for my desktops. Also, the box works fine with Linux, Windows, and Mac all mixed up. Since hitting twice scroll lock followed by the 1,2,3,4 works flawlessly, I rarely use the "Select" button or the remote that came with it ... I liked the 4 select buttons of the Iogear box I had before, and also the fact that you could independently choose where the audio came from - actually the TEsmart people could add that as a feature for newer boxes - sometimes is useful to use one computer but continue getting audio from the other, but is not fundamental, the audio also works flawlessly using the HDMI from all the computers/OSs that I use.

Affordable HDMI KVM

For some reason, while HDMI switches and USB switches are cheap, a HDMI KVM switch generally is hard to find or very expensive. I took a chance and ordered this one and am very pleased. It took a long time (3 weeks maybe?) to come from China and arrived in a sketchy looking box. But I plugged it in and it works like a charm. As others have said, to get the "special" keys on my keyboard to work (volume up/down, etc) I have to plug it in as a generic USB device which makes the hotkeys to switch between machines on the KVM not work. But I use the button on the front anyway. Only minor nit is I wish I could make it not beep when switching between computers. I've been using it now for a couple months and am very happy.
