4K HDMI KVM Switch, 4 Port HDMI USB Switch for 4 Computer Share a 4K@30Hz Monitor and 3 USB Device Keyboard Mouse Printer, Including 4 KVM Cables

Very impressed by this KVM. Ir comes with 4 dual split HDMI/USB cables that cost more than the whole thing itself. It was super easy to set up. connect the split end cable to a HDMI port on your PC and the other to a USB 2.0 port on your PC (output). The other end of that cable goes to HDMI 1 (input). Repeat process for 3 additional computers. This device lets me share 1 wireless keyboard and mouse and 1 monitor with up to 4 computers. It works on Windows, MAC, Linux and even a media box. The KVM is very small and even comes with an external switcher. Have not experienced any of the issues the negative reviews state. It just works. I got an open box one for $27, and it if dies in a year, who cares. For the price, I'll gladly get another. Have tried KVM switches that cost over $100 and they don't work as well as this. If you are worried about a mess of cables, I tied my up with Velcro cable wraps so its out of the way. If you want an easy way to share multiple devices with one monitor and one keyboard/mousse, wired or wireless, this is the one to get.

It's not working for the insignia tv, but it works well for dell monitor. In signia I could not able to switch to my hp PC back. But Lenovo pc switching is good

I should have read the reviews before I purchased this KVM switch! I need a KVM switch for use in a Linux and Mac environment. This KVM’s HDMI does not work with any of my Linux servers and workstations. The keyboard/mouse functionality works just fine. However, none of the systems, with an Nvidia RTX or AMD Radeon GPU, would work at all.

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!

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.

Very good crisp picture, there is minimal fuzzing. I like that the USB/HDMI plugs are in one cable from computers to switch. The wired remote works great. Only quip is it doesn't away power up defaulted to position 1

works fine for both linux & windows.

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.

This is a budget KVM switch for connecting upto 4 computers to a common monitor, keyboard, mouse or usb storage. This is very budget friendly - At around 2000/- INR, you get this product. It comes with 4 special HDMI cables (the one that has HDMI and USB in one end). I have attached the photo. If they also include a single HDMI cable that connects to monitor - that will be bonus. Very compact. Very minimal wiring - just the 4 cables that go into individual computers/desktops. Other than that - you need to connect your output devices - your monitor (HDMI), mouse (USB), keyboard (USB). I connected 3 input devices - one is my office mac laptop, second my personal laptop, third my desktop box. In the output section, I connected my Dell P2725H monitor, keyboard and mouse. It worked without any extra software etc. Its easy to install and use. Switching takes around 1-2 seconds and works very well. Overall - first impression - very satisfied. I will post an update after few months on the durability of this product.
