USB3.0 KVM Switch HDMI 4K@60Hz for 4 Computers Share 1 Monitor, KVM Switch 4 Port with 3 USB 3.0 Ports Share Keyboard Mouse, Support Button Switch, Plug and Play

Setup was really easy, no drivers needed and it worked right away with Windows 10 and Windows 11. Switching between the 2 computers is fast and smooth. Video stays stable at 4K with no flicker or resolution issues. Mouse and keyboard response is solid, even using a wireless mouse. The metal build feels sturdy and good quality. The included cables work fine, though they are a bit short for some setups.

I’ve been using this KVM switch to drive my 2 laptops to share my two external screens and it’s been rock solid so far. Setup was simple — honestly, I barely needed the instructions, but they were clear enough if you did want to check them. I have an external HDD connected too. It switches smoothly between two computers and keeps both monitors running just as expected. Performance has been great — no lag, no signal drops, and no issues with throughput. It just works like it’s supposed to, which is exactly what you want from a device like this. Feels well-built too, not flimsy like some of the cheaper ones. Overall, a solid piece of gear that does the job right. It has a very small footprint too so it doesn’t take much space in the desktop- even smaller than it appears in the product images. Great price and a solid performer -I’m glad I have it.

Setup: Literally a breeze. Plug everything in and it just works. No drivers or anything. Worked for me on Windows 10, 11 and several flavors of Linux servers. Performance: The switch handles video in an expedient manner. Meaning the switching between machines is almost instantaneous. I had no rendering issues such as screen resolution changes or color funkiness. There is no distortion when inseting this KVM into the chain. I have had other KVM’s where the mouse would lag a bit. That is not the case here. In fact, I was using a wireless mouse and had no lag. To switch machines it is a simple press of a button. Switching is quick and simple. Build: The KVM is made of metal! Nice as compared to a plastic alternative. Cables: The cables that come with the unit are functional, but you may find them a tad short for some applications. Fortunately 6 foot USB and HDMI cables are not expensive. However, in terms of quality the cables are good and present no issues. Conclusion: If you regularly juggle two or more computers at one desk, or have multiple servers in a closet this is the ticket to cleaning it up. Sharing a monitor between 4 systems is a worthy benefit. This unit is priced well and I feel it is a good value in terms of performance.

The USB ports are not working. While the video is passing through correctly, the USB ports for keyboard, mouse, and webcam are not functioning, which makes this product useless. Update: The USB cables from the source to the KVM Switch are required for the USB peripherals to work. Once setup correctly, it works like a charm. The label on the power switch is wrong (OFF/NO) and the instructions could use another entry in the troubleshooting guide.

I’ve been using the USB3.0 KVM Switch HDMI 4K@60Hz (4 Port) for a few weeks now, and it has made my multi-computer setup so much easier to manage. With just one monitor, keyboard, and mouse, I can switch between 4 different computers effortlessly. The button switch feature is smooth and responsive, and the plug-and-play setup means no hassle with extra drivers or complicated instructions. The 4K@60Hz video quality is excellent—everything displays crystal clear with no lag or flicker. This makes it great not just for work but also for video editing and streaming where high resolution is critical. The addition of 3 USB 3.0 ports is a huge plus since I can share my external hard drives, webcam, and other peripherals across all devices without constantly plugging and unplugging. I also appreciate how compact and sturdy the build is. It doesn’t take up much desk space, and the connections feel solid and reliable. Switching between systems is instant, with no delays or disconnect issues, and the performance has been flawless so far. For anyone who works with multiple PCs or laptops, this KVM switch is a time-saver and productivity booster. Whether you’re a professional, gamer, or someone who juggles work and personal systems, it delivers exactly what it promises: efficiency, high performance, and convenience. Highly recommended!

I am a technical support person and requiring monitoring of several live client facing platforms. This KVM switch made my job so much easier, now with only one large monitor, single keyboard, and mouse I am able to do my job with one large computer monitor vs four screens! A real game changer for me because I can now switch between 4 different computers effortlessly with the push of a button and don’t have to slide back and forth to each computer. The push button switches quickly, smooth, and responsive. The real hidden benefit is set up with the plug-and-play which requires no effort installing extra software drivers or complications interfering with different levels of operating system. The USB3.0 KVM Switch HDMI 4K@60Hz (4 Port) provides 4K video with crispness and no frequency flickering response issues. In addition, the 3 USB 3.0 ports is beneficial for connecting peripherals like external hard drives, webcam, and printers – once connected all the devices can be shared. Overall, the price is competitive and construction of the KVM switch in rock solid and only requires a small footprint on your desk – not to mention it looks pretty cool – I highly recommend this for technical people trying to simplify their usage of multiple devices.

Great little KVM, I used it to run 2 dual monitor setups and I worked great. Setup is very easy, basic plug and play. Device switching is smooth and has minimal lag. I’d recommend it to anyone needing a solid 2 system KVM. Small footprint takes up minimal desktop space.

Update after 1 week of use: I received a new gaming monitor which I would like to run at 4k@120Hz. I have tried all sorts of configurations to make it work for both monitors and none of them works reliably. For that I even purchased 8 high-quality 8K HDMI 2.1 cables and a super expensive Thunderbolt 5 Hub (just to get reliable dual screen with one port). Sometimes one of the monitors will go black, sometimes it falls back to 30Hz. Sometimes both screens keep pulsing slightly brighter for a split second, repeating once every second. Sometimes I lose my HDR settings. Sometimes I can't even enable HDR. Sometimes the screen color is washed out (almost like enabling HDR above HDR). At this point it is no longer an NVIDIA card issue, because I plugged both monitors to my integrated graphics (9950X3D). Sometimes powering off and on the KVM switch fixes it, sometimes not. Resolution/refresh rate issues most often happen on my macbook, issues with Color and HDR settings are more likely to happen on my PC. --- Affordable, easy to set up, no driver needed. I think it's a good buy for most users. A few gripes: 1. I have an old RTX 3090 graphics card. Either the card itself has some defect or it doesn't play well with the motherboard + the switch, or it's an bug in the NVIDIA driver, or any combination of these, but I've experienced a lot of BSOD of either KERNEL_SECURITY_CHECK_FAILURE or VIDEO_SCHEDULER_INTERNAL_FAILURE, only when my computer is awaken from suspension. It seems there is no such issue if I connect my CPU integrated graphics (AMD) to it. 2. Very low resolution during boot up process if I use DP to HDMI cable. After loading into Windows everything is fine. If I use HDMI-HDMI cable it also works fine. 3. Sometimes my USB keyboard/mouse are not recognized during boot up, meaning I cannot enter BIOS settings. No 1. is a major issue for me, but I can't attribute it to this product only. Otherwise I'm pretty happy about it.
