KVM Switch HDMI 4 Port Support Ultra HD 4k@60hz for 4 Computers 1 Monitor, HDMI USB Switch with Audio Capabilities Support Hotkey Mouse, EDID, Wire Remote Push Button Switching, Plug and Play

I tested this KVM switch with 3 different computers: A Windows 10 deskside tower, a Ubuntu Linux 22.04 deskside tower, and a Windows 11 laptop, as well as an HP LaserJet 1012 printer.All three computers were able to transmit sound via HDMI to my 23 inch diagonal monitor's internal speakers. I also successfully tested non-HDMI audio output on the Linux computer via the combination USB/3 mm audio cable to a separate 3 mm audio input to my monitor's internal speakers. I was able to change the Linux audio output between the HDMI and 3 mm audio output using the Sound Settings application.The printer worked on all 3 computers. (I had the printer itself plugged into the USB 2 hub port in the front of the KVM switch.)The only minor issue I encountered is that my Logitech wireless mouse transceiver only worked reliably when plugged into the other USB 2 hub port of the KVM switch. The wired keyboard worked fine when plugged into the intended keyboard USB port on the KVM switch.

Devices plugged into this KVM:Desktop ComputerMac MiniHome ServerIntel NUCFirewall Appliance (Router with HDMI)Work-From-Home LaptopThe reason why I bought this KVM is not only for my computers and servers, but also when setting up homelab equipment such as a couple of Intel NUCs for setting up whatever I can think of such as Proxmox or OpenStack.Of course, since I used to play games, I don't get 4k at 120Hz, which is fine because even if I plug my computer directly to my OLED TV, I cannot tell the difference between 60Hz and 120Hz, so since I only play single-player games, HDMI 2.0 is fine for me. If I can tell a difference between 60Hz and 120Hz, I would probably get myself a 4-port HDMI 2.1 KVM, but again, no need. I am happy with my 16-port KVM setup for my home use. And plus it has rack ears! Got to have it! :D

Editing this review.My first 2 cons turned out to be my mouse. I moved it to a different port on my computer and I have yet to see these issues resurface. The problem with the F-keys remains.I also want to comment on JideTech support. After submitting my initial review, JideTech reached out to apologize and give me a full refund. That was unexpected and very nice to see that they proactively care about their customers.Since 2 of my 3 negatives cleared up and JideTech’s asked to help make this right, i changed my review to 4 stars.——Pros:1. It is very easy to setup2. HDMI picture quality looks great3. When it works, it works great4. Feels very solidly builtCons:1. It randomly switches from input 2 to input 1. Sometimes this results in the need to power off the kvm and power it back on before input 2 works again2. The mouse will occasionally “stick” and repeat the last click command for about 10 seconds3. The F-function key row does not work. Not a complaint about the product as I should have read and known about it before purchasing. However, not having the Function keys is a real impediment to some thingsI really want to like this product, but due to the above cons, I’m going to have to continue my search for a better KVM

In the modern era of 4K 60 Hz monitors and fancy programmable keyboards, KVM switches have faced an increasingly recalcitrant set of equipment with narrowing opportunities for compatibility.Nevertheless, to my utter delight I have  been able to use the 4-port Jidetech KVM with the following, very difficult, setup (NOTE DISCLAIMERS BELOW):• 2021 M1 Max Macbook Pro 16"• Dell XPS 9310 2-in-1 on a Dell WD19TB Thunderbolt 3 dock• 3840 x 2160 (4K UHD) @ 60 Hz Samsung UN48JS9000 48" TV over HDMI 2.0• Kinesis Advantage2 keyboard• Two (left + right) Evoluent Vertical Mouse 4PROVISOS:• The Kinesis and Evoluent USB devices listed above only work when plugged into their own *powered* USB 2.0 hub, and the hub plugged into the front (data) USB-A port on the KVM. I leave the KVM's unpowered keyboard/mouse USB-A ports on the back unused, except when I plug in a standard "dumb" keyboard to use a hotkey, like when I turned off the beeps.• The M1 Macbook Pro only reliably connects to the KVM using a Thunderbolt 3 (not USB-C) dual-HDMI adapter. I use the Sonnet one. I emphasize: NOT USB-C. The internal HDMI port and USB-C HDMI adapters all result in highly variable connections, from blank screens to TV noise to successful connections that don't survive sleep.• The Dell XPS laptop is more tolerant of a simple DP-to-HDMI adapter (presumably off the USB controller), but ... see below for caveats.• The thin Redmere HDMI cables I was using all eventually ended up with flicker/noise/blank screen. The provided HDMI cables are far more reliable.Kinesis has famously said that their Advantage keyboards don't work with the vast majority of KVM switches, and they are correct. Even with the Jidetech the Advantage2 does not work in its back, unpowered, keyboard port. So the fact the Jidetech KVM works with my Advantage2 through a powered hub into the front data USB-A port is a brilliant discovery.Extending your USB devices through a KVM may cause certain devices to end up "too many hops away" from your computer's USB controller. This was a big problem for my Plantronics Savi MG8220 headset and Calisto 7200 speakerphone, which can only withstand being two USB hubs away from the XPS laptop (WD19TB dock -> powered USB 2.0 hub) before causing Windows 10 to throw a warning. I had to plug them into a separate USB 2.0 hub (and thence into the WD19TB dock) so those devices are not part of the KVM switch.Even worse, if you're already pushing the limits of the data bandwidth your controller can handle, adding one more device (like the KVM switch itself) can cause you to exceed that limit.For example, I was hoping to use the WD19TB's own DisplayPort jack (with a DP-to-HDMI adapter), rather than purchase another Thunderbolt 3 HDMI adapter like I have to with the M1 Macbook Pro 16". But I have so many USB devices attached I have to bump off at least one USB device in order to retain enough data bandwidth for the WD19TB's DP port not to cause artifacts and KVM connection delays. So I will be getting a Thunderbolt 3 to HDMI adapter for the WD19TB hub as well.So all-in-all, as with 100% of other KVM switches, the Jidetech KVM is no slot-in affair.But it truly is brilliant that my above setup is switchable at all, and reliably so.For this, never mind the detailed instructions and provided high-quality accessories (like the five superb HDMI 2.0 cables), and the fact that mine is a actually used copy from Amazon Warehouse — 5 stars.

The product looks solid and made of quality material. It comes with a set of 4 HDMI and 4 USB cables to connect to PCs or laptops. My setup was 2 laptops and 2 desktops and it switches well between all of them. There is a very little delay maybe a second, but I'm fine with that as long as it does the switching job. It has the remote panel to switch between devices, but the switch itself has the 4 buttons on it to be used for that. It also has hot keys and mouse option as well to switch which works great as well. I use the mouse option and one of the images shows the hot key instructions. So far so good. Haven't tried yet connecting a printer to see if it's shared between all devices. I recommend.

Archaic garbage. Devise will not recognize wired or wireless usb keyboard or mouse. No support option from supplier. Back it goes.
