KVM Switch HDMI 2 Port Box,ABLEWE USB and HDMI Switch for 2 Computers Share Keyboard Mouse Printer and one HD Monitor,Support UHD 4K@60Hz,with 2 USB Cable and 2 HDMI Cable

just what i needed to connect both macbook m1 pro and a windows mini pc to a single 4k monitor and wireless keyboard+mouse. It works really well with Amazon premium wireless keyboard and mouse. Logitech m series mouse dongle has problem with mac 50% of time, i had to flip the mouse, do a switch off and then on to get it working in mac. It was able to output 4k 120Hz from my windows mini pc and 4k 60hz from macbook m1 pro (60hz is a limitation of this mac hdmi). Overall very happy with it.

I now have two of these, and they really are junk. This KVM is far too quirky for any casual user. Almost amusingly, as a prelude to the chaos to come, I received this message before I received either of the KVMs:Nov 8, 2022 5:08 PMHi: Thank you for shopping with us. Amazon seller ABLEWE has encountered an unexpected problem with completing your order. --- Message from seller ABLEWE: Dear Sir/Madam, Thanks for choosing ABLEWE KVM Switch. Here we send you some use tips: If you connect mouse/keyboard and monitor at the same time. Please confirm that you have plug both usb cable and hdmi cable from kvm to each laptop. Because the signals transmitted by the Four ports are different. In the case of any problem, please feel free to contact us. Our customer service will be available to solve your problem within 24 hours. Again, thanks for buying. Sincerely, Alice ---There is no customer support as far as I can tell. I did respond to ABLEWE after receiving an email from them about reporting issues. I responded to this message and received only messages that I had “already completed the survey”. I had never even received a survey or any message besides the “ unexpected problem with completing your order” message.So there is exactly ZERO customer support.I bought this to use this primarily with two Apple Mac mini's and sometimes a Samsung Galaxy Windows Notebook. There is nothing wrong with the Mac Minis until they are connected to the KVM. With the ABLEWE KVM both minis struggle to boot with keyboard, mouse and video issues. The Samsung Galaxy Windows notebook behaves oddly as well.The Macs often go into a mode where they detect that they need to update macOS and indeed do proceed with a reinstall which isn’t really a reinstall but something relating to fixing an error… likely in keyboard or mouse configuration. When the KVM does not sense the keyboard properly the Macs often suggest entering a password to unencrypt the disc, which turns off FileVault. Now I simply keep rebooting until they work.My reason for buying the second KVM was that they are cheap and I was hoping that it might be better but it exhibits the exact same issues as well. I have way too much work to get done to screw with these at this time but when I come up for air I will be doing a lot more research before buying.I've used IOGear KVMs for decades, but they invariably need to be replaced with every major macOS update due to sensing video resolution so I didn’t try them again and instead tried the ABLEWE KVM, which is anything but Able.I’ve been playing around with workarounds such as having the Macs never shut off, but stay in sleep mode while the KVM maintains the state with all connected to a UPS. The key to keeping this working is keeping it always on so that the KVM doesn’t lose its cached state. I need to get lots of work done so I'm essentially avoiding shutting anything down. Rebooting can take hours to get it working again.So I’ve bought myself some time to properly research a better KVM. Although I do have this working it is amazingly quirky. I’ve found ways to leave certain components on all of the time to cache settings in the powered KVM, all on a UPS, keeping computers on but in sleep mode. So although these are real junk I’m staying with them for now as I research a bit to get a quality KVM.

It's a simple device. Like an A-B switch. Except this switch has rare glitches. It is made very well but it's not quite perfect. I've been working with Customer Service and have finally come to a solution that works for both of us.PROS:- I like the GREEN indicator for one side, or press button and toggles to BLUE.- Also, it has a nice touch button, good size, and confirmed presses as it makes a clicking noise when you press it (as if the color change wasn't enough).- It comes with pretty much everything you need for cables, assuming you had a work computer system already (existing cables for monitors, mouse, keyboards, etc.)- Only wish the common HDMI output to the monitor was on the backside... (but that's for aesthetics).- low profile. Only 1 tier level of plug ins, and the height is only 18cm (body). The button adds a couple more millimeters. (see pic... you'll notice there's plenty of clearance in my situation, to press the button with the switch under the monitor)CONS:The switching will freeze on rare occassion.1) The color switching/toggling just stops. In other words, the switching fails. No going back or forth. (OR)2) The mouse and/or keyboard just won't transmit their information through. They are still powered on (mouse still has RF connection, and the LED keyboard (wired) is still getting the power light on. This will occur when trying to switch, but instead of switching, one of the devices just fails working.3) (as mentioned earlier... which is a preference) the HDMI cable output to the 1 monitor comes out from the front of the box. That's just for easier cable management, but not a major one (see my pic... the center cable coming out the front, which I duct tape the cable down, but it's actually in the dark. The camera boosted the brightness so it's really darker then it is. The other cable coming out the front on the left side is my keyboard, so it is pointing in the correct direction... which is toward me, and my keyboard).To reset this switch to work again, I have to disconnect all the computer side cables (USB and HDMI from video cards), to remove power to this switch. Then it's a power reboot when I plug in. Then the switch will work again.UPDATE: 7/29/2022So I've been in contact with Customer Support and they are great. That's very helpful and makes knowing that they are improving and trying to be a great company. They are willing to replace the KVM switch, but unfortunately, I've moved overseas and can't get the item shipped to me.On another weird note, it finally started working for a few consecutive days now. I know I probably jinxed myself, but I do like this switch (when it works!), so glad to see that maybe a reboot of it made the correct adjustment to whatever the problem might be.UPDATE: 8/2/2022So after working with Customer Service (which has been top notch, and that makes a lot of difference), they are making an update. I still recommend this product. Get it now. If you have some issues, then work with Customer Service, or wait for the next model (coming soon). It's worth it. And for this price (even without any discounts), this is a great deal for a KVM kit. (Kit - meaning, it comes with the USB cables and HDMI cables that you would need to fix up your switching needs. Also, cables are long enough if your PCs/Macs are in the same desk area (1 meter length cables.)And it's still working good... so maybe my issue is gone? TBD, as I've only been using it 2-3 times a day.
