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

I have come to not expect much from cheap Amazon electronics, but this was a DEAL. It works flawlessly and I can switch between my four computers easily. I saw in the reviews that some people had a lag, but I think that is their equipment because mine switches fast. The remote allows you to hide the cables and just bring out the switch. Sure, it would be better if the remote was wireless, but it is not a big deal to me. You couldn't find a better deal for the $$. The only negative I have is that the cables could be a little longer, but this was an all time best buy for me.

Excelente equipo. Es justo lo que deseaba para mí trabajo. Me es muy útil al conectar 3 pcs a mi monitor, puedo trabajar mejor sin desconectar a cada momento el monitor se una PC a otra, ahora solo con un botón puedo intercambiar las computadoras con el mismo monitor.

I deducted 1 star because the CONS are strictly based on my personal preference. I should have done a little more research before purchasing, therefore, I don't think it's fair to penalize the product when I didn't due my due diligence.This works!!!! That is the main thing. If you're not as picky as I am (see CONS below), than I think you'll be satisfied with the product.PROS:1. The setup was extremely easy.2. It works.3. It's black in lieu of the standard (?) green models that are more predominate on the market4. The attached "switcher control" is labeled5. It comes with cables.CONS (BASED solely on my personal preference):1. Feels very flimsy, unlike the standard(?) green KVMs2. The time between switching from 1 PC to another is longer than I have patience for.

At the moment I'm only using 3 of the 4 available ports. A raspberry pi 4, a mini pc running ubuntu, and a win 10 laptop. Switching can take a few seconds, it is not instant. Depending on you needs you may want each device to use its native audio. If for example you want audio from PC #1 but you are working on PC #2. In my case I want the audio from each routed through the switch. My monitor HDMI monitor does not have a speaker so there were two options. One would be to use a black box to strip the HDMI audio from the feed from the splitter to the monitor and connect that to external speakers, this needs a clunky box, a power source and a few extra cables or Option 2 which I chose, that is a USB DAC in the spare USB port of the switch and plug that output into external speakers.

Returning it back as the USB cables are very short . In my laptop , the HDMI cables are left side and the USB on the right side . The USB cable is not be able to connect to the other end. so not usable for me .

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!

Frequently loses mouse connection, I assume there is not enough power available to drive the usb mouse. Using the kvm to switch between a linux and windows laptop. I realized after opening the box that I’ve used this brand before and had the same problems. I can’t really recommend this product.
