AV Access KVM Switch Dual Monitor 2 Ports 4K@60Hz, 2K@144Hz, HDMI USB 3.0 Switch Extended Display 2 Monitors 2 Computers, Ultra Wide Screen PC Keyboard Mouse Switcher, Hotkey Switch, 2 USB 3.0 Cables

This does exactly what I wanted. Work laptop plugged in with USB-C which handles 2 displays, mouse, keyboard, webcam and speaker. Then a personal desktop with 2 video outs (Display Port & HDMI), the mouse, keyboard, webcam and speaker again.Price wise I think it was fair, KVM's can run very expensive and I think the price here was towards the lower end of the scale. That did worry me as I thought it might cut corners but I have to say I'm very happy with the functionality and the build.Lessons learned, dont buy extra cables, it comes with HDMI, DisplayPort, USB-A & USB-C. I did because I did not see in the advert, I have spares now. Also, and this is just me and not understanding how things work but you plug the laptop in with the USB-A and get duel display. HDMI does not work like that, you want 2 displays you better have 2 video cables coming out the back of your PC. Thats just me and my understanding, once I worked that out things worked fine!

I’m using it with a 3440*1440 144hz ultrawide, and due to it not being a TB dock you can only achieve 100hz at that resolution through the dock. Very happy with that though as wasn’t expecting anything more for a cheaper priced dock. If you want full 144hz you will need a much more expensive unit.Every once in a while I find the screen won’t come on if I’ve changed a display setting, but usually pressing the switch button to go off and then back to the device turns it back on again, this could just be an issue with my display rather than the unit.Overall very happy and does the job well. The listing doesn’t really make it clear but it does come with with all cables you need to set it up (hdmi, display port, usbs, etc) only thing it doesn’t supply is an additional usb C power supply if you want it to also charge your laptop but that wasn’t expected anyway, as you’d just use the one that came with your laptop.

Having spent much time experimenting with cables and so forth to try and get a gaming PC and a work laptop work properly through a KVM (usb-c laptop with display output, and a games machine with 3 DP and 1 HDMI), this is the only solution I have found that actually works, and works well. Nice piece of kit, perhaps worth mentioning the included cables in the blurb. Easy to connect, easy to use.My only negative would be its size and/or there is no remote switcher such as you can often get with other KVM's (this would mean i could put it out of view and just use a little switch button to change outputs rather than having the entire thing on my desk), but a good solid piece of kit that works as intended, very happy.

Just very disappointing overall. When it works, it works well but there are just too many problems with it:1. It supposed to support 2 extra monitors at 4k (3840 x 2160) but it does not. Only one ever works at that resolution. They told me it's because my video card may not be supporting this. I can accept this but again, it should be clearly highlighted in their description.2. When I'm using my laptop monitor and the screens are connected, the minute I open Prime Video, it switches off the 2 external monitor and it won't work until I close Prime Video in my Browser. I has managed to work with Prime Video in the past but I get a warning from PV that I'm not displaying my videos at high res. I'm ok with lower resolution. What I'm not ok with is that I have no control over this and cannot used my external screen with Prime Video! Very poor!3. Today for example after having giving up on #2 for quite some time, my 2 screen just refuse to work! I've rebooted my laptop, my kvm numerous time and they just won't connect.And before you can say, it's something to do with my laptop. It's not as every time I go to the office and connect to my docking station (from another brand), it works 100% of the time, not matter what, so it's definitely has something to do with this KVM.Really disappointed overall as it's not that cheap and it's unusual to have hardware that does not do what it says it will do.

This is a review for 4KSW21-DM KVM SwitchI needed the ability to switch everything between work and personal PC - two monitors (not chained, mixture of HDMI and Display Ports), camera, wireless Bluetooth headset, mouse and keyboard. Dam that's a lot of cables! Both of my PC's have a USB 3 port, checked before purchase. After finding space and tidying all those cables it really did just work.I am going to mention the unit itself because it looks and feels like a quality built device. I like that it is not all plastic and that all the ports are sensibly labelled. It came with a manual that I have not had to look at.I have USB keyboard plugged into the USB 1.1 socket as suggested. I have not changed the hotkey from TAB and can say that TAB + 1 / TAB + 2 works without issue and I have not had any issues with this interfering with either PC.There was a suggestion that this device interferes with wireless router. I have a BT HomeHub less than 1m away from the switch and so far have not experienced any issues.Personally the fact that the Jabra headset reconnects when switching was a big win, have had issues with this headset in past (MacBook) but it is so good I do not want to change it.All in all I am very pleased with this purchase.I have not used the device in USB mode, I have no need for that at the moment.I have not received any kickbacks for this review, though am not averse to receiving some after the fact :-). I purchased the unit after some research and hope this helps other people decide.

Straight forward to instal and use out of box. However a remote to switch would have been improved the experience
