Works well at 4K60. Switching time is pretty quick, my monitors take longer to readjust than it takes to switch sources. The buttons aren't the most intuitive but once you get the hang of it they work well enough. USB 3.0 ports work at full speed. Pretty good value, would recommend.

Review for: "USB 3.0 HDMI KVM Switch 2 Montiors 2 Computers, 4K@60Hz KVM Switch Dual Monitor with 3 USB 3.0 Ports and Audio, 2 Port KVM Switch with Dual Monitor Cross Display for 2 Computers"Brand: Rytaki ProFirst look: the HDMI KVM Switch came in a box (23.4 cm x 17.1 cm x 5.5 cm) with the AC power cord, 4-button switch, Micro USB to USB-A cable (for the switch), two USB-A to USB-B cables, and instructions.Opinion: The micro-USB cable and older USB-B cables makes me think this is an older model KVM switch. I found the cables quite short and needed to use USB extensions, plus HDMI cables that weren't included.I have two computers and two monitors, and I've been having trouble with other KVM switches where the new monitor doesn't always turn on when I switch, or come and goes, and I have to switch the KVM power on and off to get it to turn back on again. This one seems to be working better than the last ones, but occasionally still has the same issue.

The Rytaki Pro USB 3.0 HDMI KVM Switch for 2 Montiors and 2 Computers (4K@60Hz) with 3 USB 3.0 Ports and Audio is a rather unique KVM as it also supports Dual Monitor Cross Display for 2 Computers. It is housed in a metal box and comes with a UL listed 12V power adapter, a wired remote (with detachable cable), two USB 3 cables, and a manual.I have found this KVM switch to be quite functional with my 2K (2560×1440) monitor as it supports its refresh rate of 144Hz and has fairly quick and seamless switching between PCs with the EDID function that keeps the windows and icons in their place. It also has the very cool feature of matrixing the PCs letting you display monitor one or monitor two of both PCs at the same time. (on the two monitors)It also supports built-in stereo audio (in & out) that shows up as an extra USB sound device on each PC.Along with the regular HDMI audio (if supported by your monitor, etc).However, this is the first KVM switch that will not handshake properly with my AV system (4K@60Hz HDMI 2.0). I only managed to get it to work once with a 1080P signal. This is not a cabling issue. Due to this issue I couldn't test the DV, HDR10, 4K, etc functionality. -1 star.I assume that this was some strange compatibility issue with my AVR (Yahama), and 4K monitors would likely be fine.Overall I think that this is a good quality device and am giving it 4 of 5 stars.

The 4k hdmi kvm switch is great. It is able to cast to two different monitors from two different devices which is really useful for a working professional. It also features a clickable switch between channels which is great. There are however a few minor stick points. Firstly, it only runs at 60 Hz which is good for everyday life but not so much for gaming. Secondly, the port for the switch is located only at the front which depending on your set up my result in cables showing more than they need to. Other than those two, the product works as intended.

This review is for the USB 3.0 HDMI KVM Switch by Rytaki ProThis is a great KVM switch that likely would have been rated 5 stars if not for one quirk that is super annoying and I still can't figure out.The switch is made of what appears to be high quality powder-coated metal. It has a sticky bottom so it will not slide off your desktop surface should you wish to mount it there. The KVM comes with a DC power input and adapter, 1 USB-A to -A cable for a remote switch, which is also included, and 2x USB-A to USB-B cables for controlling the PCs/desktops/laptops. It does not come with any HDMI cables, you will need to supply up to six of those yourself.The front of the unit contains 4 LED-lit buttons and three USB-A inputs (although they are labelled outputs, which is just poor English I think). There is also a power rocker switch (on/off) and a USB-micro port for the remote switch which could be mounted on your desk surface if you choose to hide this KVThe back of the unit contains 6 HDMI inputs and two USB-B ports with boxes surrounding two HDMI ports and one of the USB inputs - these are labelled Computer 1 and Computer 2.) I really like that all the HDMI and the USB-B ports are all on the back as these all lead to the computers and monitors, and the front USBA ports are for peripherals such as mouse, keyboard, external hard drive, USB Flash drive, etc. I have worked with other KVOnce hooked up, it is fairly straightforward for two of the buttons on the KVM switch and remote switch: Button 1 displays both monitors and controls the USB peripherals for computer 1. Button 2 controls/displays computer 2. This is where things get a little funny. There are also a 3rd and 4th button. What these are for is anyone's guess... the monitors seem to jump around and I don't know if there is consistency to which PC I am controlling with the mouse and keyboard. The manual is barely written in English and is no help with figuring this out.The only improvements I can think of for this units would be:- include a bracket (or at least pre-drilled holes in the metal case) that you could mount this on a wall, on the side of a desk, etc.-update the power adapter itself to make it slimmer and be oriented horizontally instead of vertically that way it does not interfere with another plug below it-reduce the number of buttons from 4 to 2. Having FOUR buttons to control TWO computers makes no sense and I still can't really figure out what the extra two buttons do except confused the heck out of me displaying monitors for each computer at seemingly random patternsAside from that, I have figured out that button 1 displays computer 1 and button 2 displays computer 2 and I won't use anything but those two buttons. This unit is so worth the price ($80 Cdn at time of review with a 20% off coupon at checkout.) Just the button thing makes this a 4 star instead of 5 star product.
