If you have to use multiple computers simultaneously, you will need to deal with various keyboards and mice. Further, you will need to install as many monitors as computers. A software KVM can offer distinct benefits over a hardware solution. You can avoid the tangled web of cables, as well as switch between or among PCs through hotkeys or an app, rather than pressing a physical button (although some hardware KVMs offer hotkey-based switching, as well). In the past, KVM switches were only used in workplaces to increase efficiency, but they have also found their way aboard home stations. The market is medium-sized, with several local and international power electronics companies producing these. Switching might take longer than most KVM switches, probably because of low power consumption. Ports Using a USB-C KVM switch negates this requirement, as USB-C allows data, power, and video signals on a single cable. Thus, USB-C KVM switches minimize wire clutter and help optimize your workstation. Video Output
The OME-MH21 provides control to a display through IP, RS-232, IR, or CEC*, without the need for a separate control system. This simplifies system design and integration while reducing costs. With automatic display control, the OME-MH21 can trigger a display to power on automatically whenever a laptop or other device is connected. At the end of the presentation, when the presenter disconnects the laptop, the OME-MH21 forces the display to power off. Ease of presenter interaction with the system, and the savings incurred by automatic display shutdown provide a significant return on investment. The OME-MH21 display control capability can also be triggered by an external control system.
Customer reviews
The TESmart USB-C KVM switch is an externally powered device. Despite that, it has an additional USB-C port for power pass-thru to enable Power Delivery to the host computer. While it adds to the wire clutter, it also gives you flexibility if you use the switch to connect desktop computers. In this guide, we’ll talk mostly about domestic buyers or small office workspaces; however, if your needs are more extensive, you need a pre-buying audit before entering the market. Number of computers Automated room control features are also included through GPIO ports, besides RS-232 and occupancy sensor connectivity. KVM switches with only a few PC connections usually do not have a dedicated power supply; they take power from the monitor’s power supply or through the USB bus. Bigger or higher-rated KVM switches usually have dedicated power supplies, especially if they can charge connecting devices. The absence of a dedicated power supply seems attractive, but we only recommend smaller KVM devices, like the ones switching between two or three computers. Sabrent 2-port KVM switch offers you a lot in a very narrow price range. The device can provide 4K video at 60Hz and has two USB-C inputs for host computers. In addition to that, it has two USB-C ports with power pass-thru to charge your laptops/gadgets with up to 60W Power Delivery. The switch does a beautiful job of using up all of the sweet power and data transfer capabilities of the USB-C port.
The switch does not use a power adaptor. Instead, it gets power from the USB bus. Of course, that means that one of your computers or the monitor power supply will end up charging the other. For some, it is still a better power consumption profile than powering the switch and your laptops separately. You can connect the keyboard and mouse to one monitor and then switch control over to another device. You can also connect multiple computers and a USB driver via a switch to share information across the devices. The switcher also thrives when it comes to audio capabilities, offering analog audio de-embedding features as well as support for DANTE/AES67 network connection to send DANTE/AES67 audio stream directly to a dedicated audio system.Compared to the previous model, this switch features two HDMI ports and supports a dual-4K monitor setup, making it the go-to choice for users who need additional screen real estate. Our testing gear comprised a Viotek GNV27DB curved gaming monitor, two Windows 10-based desktop mini-PCs we recently reviewed (the Geekom IT8, and the Beelink GK Mini), and a standard wired gaming keyboard and mouse from Logitech. In turn, we set up each KVM device and switched between or among PCs 10 times, using a stopwatch to measure the switchover time and then averaging the results. To test the audio and video quality, we played a 4K HD movie (our old testing stalwart, Tears of Steel) on each PC through each KVM switch in turn to our Viotek monitor. We also watched the same video with the PCs direct-connected to the monitor to see if any perceptible difference. This two-PC-capable KVM switch uses HDMI for the connection to the primary monitor's input, as well as to the outputs from your connected systems.

It can host two computers and has two additional USB-C power pass-thru ports that support 100W Power Delivery per host, making it a hard-to-resist deal. USB switches are another KVM alternative, of sorts. They look just like KVMs, and will likely show up in the search results if you're hunting for a KVM from a retailer. But they have one critical difference: no video support. They will only allow for switching of a keyboard and mouse. That means you can switch between computers with a keyboard and mouse, but a standard, inexpensive USB switch will not pass through a video signal. If your monitor has dual video inputs (most do), and you can attach a system to each, that arrangement can work as a KVM surrogate along with a USB switch, but you'll have to switch the display input via the monitor OSD and the peripherals via the USB switch separately. That's a much less elegant solution than a "true" KVM.
USB type B interface for connection to a host PC, plus two USB type A ports for a peripheral device such as a microphone, speakerphone, camera, or touch display Interestingly, the KVM switch also supports 8K@30Hz video using a single monitor setup, making it ideal for workflows requiring high-resolution monitors. Unlike most KVM switches, which offer only two USB ports to connect peripheral devices, this switch provides four, enabling you to share more than just your keyboard and mouse. If you're looking for a four-PC-capable KVM switch and choosing between this one and the Tcnewcl, the biggest difference is that this one has four USB ports for peripherals instead of the Tcnewcl's three. That's a lot of additional value for only a few extra dollars.If this kind of teleportation magic sounds like something your home setup needs, here’s a guide to finding the right KVM switch for you. KVMs are venerable tech, but once you start shopping, you'll see a fair bit of nuance around them. We're here to help.
If you have only two computers/laptops, getting a powerless device and saving your desk space from clutter makes more sense. Ports Centralized, network-based configuration and management of Atlona IP-controllable products and systems
Feedback
You can connect four different computers to four different devices. On top of that, it works with Mac, Windows, and Linux computers. While not as robust as the previous entry, it still covers the main systems. Also, this model has a wireless remote compared to the Tcnewcl's wired remote, meaning more flexibility and one less cable to fuss with. Your desk could be completely de-cluttered (KVM out of sight, out of mind) with only the wireless remote in view. Given the price, the remote, the number of supported PCs, and the number of peripheral USB ports, this is the highest-instrinic-value KVM we tested. While a dedicated power supply does add to the cable bundle, it also helps protect your system against poor electric efficiency. A manifestation of this fact is the heating up of the monitor’s or PC’s power supply when connected through a powerless KVM switch.
