I had been using my TrippLite VGA KVM for years and putting up with a pretty terrible picture for such a long time. Finally after realizing nearly all my regularly used machines had HDMI natively, I ditched all the VGA cables and dongles and this little generic (model HK401, no brand name at all) arrived today.The improvement in video quality when using this KVM was IMMEDIATE. I'm so pleased with this thing and it was very reasonably priced (under $60). It's so small I couldnt even believe it was a 4 device KVM, but here it is driving 3 PCs of mine, 2 Macs, one Linux and one I use for when my laptop is upstairs, and it works amazingly, no issues. Audio passes through to my monitor for the active device, meaning no more need for an external pair of speakers. So much less clutter on the desk now.Pros:- it's tiny! You can see in the first picture how it compares in size to my old TrippLite KVM.- No external power supply needed. Another win for this device that I didn't even realize I wanted. Grabs power from the device(s) you are controlling, and has no problem powering my keyboard with backlight and optical mouse.- Less expensive than other HDMI KVMs I've looked at and much less than my old VGA one.- Provides an incredible picture at least compared to my previous VGA KVM.- Love the controller cables, obviously they are some proprietary format with HDMI on one end but on the other is both HDMI and a USB port. Cables feel sturdy but flexible and I like the greenish/cyan color.Cons (not many, but a few)- When pushing the button to switch inputs on the unit it sounds a little hollow. A very minor nitpick.- I'd probably prefer it to be a little bigger actually, if it means all the cables could be on one side (i.e. the back). As it is, the HDMI ports are one of the long sides of the unit, and the USB inputs are on the other. I ended up just placing it on my desk sideways until I tidy it up the cables more (second picture). Or maybe I'll leave it as is.- Finally, I do wish it came with an HDMI-HDMI cable to connect up to the monitor. Presumably they assume you're already using at least one HDMI device, I'm probably a pretty odd case in that I was not.Overall though I'm very happy with this purchase, whatever company made it should stamp their name all over it because they made one great product!

I use 4 computers and have them connected to 1 large monitor and a keyboard mouse. 1 Windows PC, 1 Mac Laptop, a Linux Desktop and a PC with ChromeOS flex - works perfectly on all of them. For the LInux desktop I had a DisplayPort output, this KVM has HDMI, so it needed an adapter but that was expected, USB is Type A, my Mac only has USB C, so needed 2 adapters, 1x USB-A to USB-C for the Keyboard and Mouse (they share the same USB cable) and 1 USB-C to HDMI for the monitor.

Having owned this now for several months I can say that, overall, this KVM switch is an excellent value. Not to say it is perfect but, for the price, the minor issues I've encountered are do not adversely affect the value.The three (minor) issues I've run into are:1. When switching to my laptop with the lid closed, the laptop doesn't seem to detect a video signal so never switches to the monitor. I have to raise the lid, switch to the laptop, watch to see the LED backlight flicker indicating it's detected the monitor, then close the lid. After that it works fine until the laptop is powered off.2. Three computers are connected to the KVM switch. Two work perfectly (Core i7 Lenovo laptop and Ryzen 5, 5xxx mini PC) but one (Ryzen 7, 3xxxx mini PC) doesn't seem to register "mouse up" events correctly. For instance, to click a button I have to click it, then move the mouse a pixel or two for Windows to register the "click". Visually, buttons on the screen shows "down" so "mouse down" seems to register properly. If I plug the mouse directly into the PC, it doesn't have this issue. I can switch to another PC, then use RDP to connect and the mouse clicks work fine. Since this PC is only used occasionally I often just connect the mouse directly when it's being used and leave the monitor and keyboard shared then move the mouse back to the KVM switch when switching to another PC.3. This may be a monitor issue, or a mix of monitor and KVM switch but if the computer signals the monitor to go into power save mode after an hour or so, the monitor loses the signal coming from the KVM switch and never picks it up again even when the PC starts sending signal again (keyboard pressed or mouse moved). Even switching to another PC with an always on monitor output doesn't bring back the display. They only way to get it working again is to turn the monitor off, wait a few seconds, then turn it back on.

Update: Not giving it a week - this morning, it would not recognize my work laptop at all. This is going back.I got this on a whim while purchasing something else - mostly b/c I needed to add more ports (previously had a JideTech 2-Port for the last 3 years) and this seemed a good deal (roughly what I paid in 2020 for twice as many ports).HOWEVERIn three years, the most trouble I had with the previous one was its wonky "switch" and even that functioned well probably 99% of the time.So far, in just one day, I've spent around 15 minutes total toggling between inputs and finally having to switch my monitor off and back on again for it to get a signal from this box. This is pretty much an absolute killer for me, as I don't feel I should need to do this _EVERY TIME_ I sit down at the desk, regardless of whether or not I am switching an input.I'm going to take a week or so to see if I can find some reasonable fix for this, or probably send it back. Glad I didn't toss the other one out yet.

This works as advertised and is the only economical 4-port KVM switch I've found. It works with 3 or 4 machines connected, and works great with Windows and Linux. Switching isn't instant but it always works after a second. Be sure everything is connected to the switch before turning the machines on to ensure that everything is detected correctly.

Compact lightweight KVM with 3 USB 2.0 for use with upto 4 devices with somewhat lengthy wired remote device selector. Takes a few seconds to switch but have to change resolution & refresh rate accordingly (Max 4K 30Hz) prior to connecting to the KVM. Nice workaround is to use the USB connection (without using the attached HDMI) and a direct HDMI connection to your main display device (but you have to switch individually to the corresponding device input on both the KVM & the display) to get HDR DV or higher refresh rates. Otherwise quite functional if you don’t need better/higher video output

Cercavo uno switch per utilizzare una tastiera con mouse wireless, un paio di cuffie con microfono usb e uno schermo con ingresso HDMI con tre computer diversi con uscite hdmi. Ho provato questo ed è perfetto, c'è anche il controllo remoto (con filo) nel caso il device fosse scomodo da raggiungere. Supporta fino a quattro computer collegati e tre device usb.

Plugged in my desktop at home and my work laptop but got no video from either device. Tried several restarts of the computers and once got image from the laptop which seemed alright. After switching source to the desktop I could not get it back on the laptop. After several tries I never got video back on it. For the desktop I got image of the source was selected only at a cold boot and at the BIOS screen. After that there was nothing. Besides the BIOS screen I got was the image I've attached here.The USB switching worked really nice though and I had no problem with that.On the hardware side of things this product felt cheap and the usb connector for the "remote" felt like it was loose although it worked.This product really got my hopes up. Too bad it did not work for me. Maybe it's my monitor who knows, but neither computer seemed to recognize that there was any screen connected. Maybe that gives some kind of tell. I did not try the switch on any other monitor.
