What to pay attention to
A few words about our best products
At Greathtek, our most popular products are trusted by professionals who demand speed, precision, and flawless performance. These bestsellers are not just top-rated because of what they do — they’re celebrated for how they do it.

Whether it’s for IT environments, creative studios, control rooms, or multi-device gaming setups, our top-performing switches deliver consistently smooth operation, high-resolution clarity, and effortless control.
Our HDMI 1 Monitor KVM Switch is a customer favorite due to its simplicity, reliability, and wide compatibility. It supports 4K@60Hz resolution, ultra-fast switching without lag, and allows seamless control of multiple systems from a single monitor, keyboard, and mouse. Compared to competing models, ours offers more stable signal processing and a more intuitive user experience out of the box.
The HDMI 2 Monitor KVM Switch is ideal for power users who require extended screen real estate.

Testimonials
This KVM switch is an excellent budget-friendly option for anyone looking to manage multiple computers from a single desktop setup. Despite its affordable price, it delivers solid performance without any noticeable lag or glitches. The HDMI supports 60Hz, which ensures smooth video output, and the USB 2.0 ports handle peripherals like keyboards and mice with no issues at all. What’s especially convenient is that it comes with all the necessary cables, so there’s no need to buy anything extra — you can have it up and running in minutes. I’ve personally used it with a Windows desktop in combination with a Raspberry Pi and a MacBook Pro, and it has worked flawlessly across all platforms. Switching between systems is effortless thanks to the single button on top — just a quick press, and you’re instantly working on the other machine. It’s simple, effective, and a huge value for the money. Considering that I once paid nearly $400 for a bulky KVM switch decades ago, it’s impressive to see how compact, efficient, and accessible these devices have become.

This KVM switch worked flawlessly right out of the box — no software, no configuration, just plug in the cables and it’s ready to go. I’m using it to connect a desktop and a laptop, both with HDMI outputs, to a single large HDMI monitor, and the performance has been rock solid. There’s no need for multi-monitor support in my case, and both systems respond instantly when switched, waking up on command with no issues displaying on the shared screen. My keyboard and mouse setup is a basic wireless Logitech combo, and I simply moved the USB receiver to the KVM’s USB port — everything worked immediately, no additional steps required. The unit itself is compact and unobtrusive, sitting neatly on top of my desktop tower with all cables routing cleanly out the back, which keeps my workspace tidy. While my setup isn’t complex, this KVM switch fulfills the need perfectly and offers outstanding value for the price — simple, reliable, and efficient.

The USB 3.0 KVM Switch HDMI 4K@60Hz has been a game-changer for my multi-computer workstation, allowing me to effortlessly control and share a single monitor, keyboard, and mouse across four different computers. Whether for work or personal projects, this switch has brought a new level of efficiency and organization to my setup. The installation was refreshingly simple — true plug-and-play with HDMI connectivity that required no drivers or technical know-how. The 4K@60Hz video support delivers sharp, vibrant visuals across all devices, which is crucial when switching between systems for design, development, or general use. Its three USB 3.0 ports are a huge bonus, offering fast and stable connectivity for high-speed peripherals like external drives, printers, and USB flash storage — all easily shared between machines without unplugging. Switching between computers is fast and intuitive with the dedicated button, and the LED indicators make it easy to know which system is currently active. This convenience has streamlined my workflow and eliminated the clutter of juggling multiple input devices. In short, this KVM switch delivers everything it promises: simplicity, performance, and reliability. I highly recommend it for anyone managing multiple systems who values a clean, efficient workspace with high-quality video and seamless device sharing.

My old KVM switch started failing by gradually losing its USB functionality — the HDMI still worked, but the keyboard and mouse would regularly disconnect. It especially struggled with my Mac mini after a reboot, often failing to recognize the keyboard unless I plugged it in directly, which became frustrating over time. I was initially hesitant to try this new KVM since it doesn’t use an external power source, but given the affordable price, I decided it was worth a shot. To my surprise, setup was quick and simple, and its compact design fits perfectly on my desk. The hotkey functionality is a great feature, allowing me to switch between devices without physically pressing any buttons, and although the switch time is around 2.8 seconds, it feels smooth and responsive for general use. Right now, it’s running on a fairly complex setup — an Intel NUC with Linux, two Mac Minis (Intel and M1), and a Raspberry Pi — and it handles all of them without issue. My wired keyboard and wireless Logitech mouse (using a USB dongle) both work seamlessly, and most importantly, after rebooting any of the connected systems, the keyboard is recognized every time without fail. The build quality also feels solid, thanks to its sturdy metal casing that gives confidence in its durability. Of course, only time will tell how long it holds up before showing any signs of wear or port failures, but for now, it’s a major upgrade and running reliably. I’m hoping this unit lasts for years — and based on the current performance, I feel optimistic.

I recently reorganized my office and relocated my photo printer to a set of wire shelves across the room from my computer desk. One of my printers supports WiFi, so that wasn’t an issue — but my Epson R1800 only works via USB, which created a challenge. My first attempt was using an old Iomega print server, but it was completely non-functional — lights were on, but it wasn’t connecting to anything. I then tried a long USB cable, hoping for a simple fix, but Windows refused to recognize the printer at all. After digging deeper, I discovered the concept of USB over Ethernet and began searching for a reliable solution. That’s when I found this device — and it worked flawlessly right out of the box. There was no software to install or complex configuration required. I simply connected the included USB cable from my PC to the transmitter module, ran a network cable to the receiver, plugged in the power, and connected the printer to one of the four USB ports on the receiver. Everything was detected instantly and worked as if the printer was plugged directly into the computer. As an added bonus, I was also able to relocate my photo scanner to the same shelving unit, and now both devices work simultaneously without any issues. This solution not only solved my connectivity problem but also helped declutter my workspace.

For the price, these little devices are surprisingly impressive and incredibly useful in the right scenarios. While there is a slight drop in color fidelity and they may not play nicely with every camera, they’re absolutely reliable for basic 1080p multi-camera internet broadcasts. I’ve used them to connect lower-tier cameras like GoPros and PTZ units to a main switcher without a hitch, and they’ve consistently performed well for what they are. What I love most is how stupidly simple they are — and I mean that in the best possible way. Unlike more expensive alternatives that come with a maze of DIP switches and unnecessary features that tend to cause issues mid-event, these just work. I’ve lost count of how many times I’ve been on-site troubleshooting a signal issue with a “smart” adapter, only to swap in one of these and watch everything come online instantly. They’re truly plug-and-play with no setup or configuration, and that makes them incredibly flexible. I’ve even used them to build a “video village” when wireless video solutions failed due to interference or when SDI cables weren’t long enough — and if there’s already point-to-point Ethernet in place, this becomes the easiest and most cost-effective workaround. Sure, the image quality isn’t studio-grade, but in many real-world situations, “it works” is the most important metric. These aren’t high-end gear, but for small gigs, tricky jobs, or quick fixes, they’re absolutely worth having in your kit.
