DVI KVM Switch Computer USB Mouse Keyboard Button Switch Control Two Computers 4K/1080: For Win98 / ME / 2KP4 / XP / 2003, Linux, Apple, MAC (DVI KVM Button)

This isn't particularly good as I had lots of issues with blank displays.Although I had no issues with Windows desktop in full HD, blank displays would typically occur in many games in full screen mode.I didn't perform an indepth analysis of the display mode, but ended up replacing this with a separate HDMI switcher and ugreen 4 port USB switcher, and that combination functioned better than this device ever did, even going up to UWQHD resolutions. Ultimately that combination has been replaced with Aimos HDMI/USB C KVM which also does not result in black screens and is similarly priced but with 4 outputs, although you'd need to source HDMI cables. That's not a bad thing though as I also had issues with cable length on this device.

This thing is really fussy, I think because it steals power through the USB connections rather than being powered itself. You need both machines powered on and powered up in sequence or it doesn't work. Also it won't work if one of your machines is a Raspberry Pi or similar because the RPi can't tolerate that much current drain so won't boot. Make sure you use it through a separate powered hub in that case. Keyboard input seems a bit intermittent too with a wireless keyboard. Overall, it kind of works but it's not exactly trouble free.

Works in some very specific circumstances but otherwise has some pretty big limitations.In short it is very pedantic about the order you plug in HDMI cables - if you get it wrong then you'll end up switching only to find a black screen, the only fix being to restart and cross your fingers that it changes its mind. There are also occasional dropouts - black flashes that, while not the end of the world, are quite distracting.If you don't think you'll ever unplug or turn off either of the connected devices then this might be the KVM switch for you, otherwise I'd go for a slightly more expensive one.I ended up returning it and buying one of the ~£35 ones on here (which is working much better).

Can't get my mouse to work for some reason, but it might be more to do with my mouse than the switch, because it didn't work on my previous switch either, but is fine in the computer. Also Can't get the hot keys to work, and no instructions in the box on how to do it.

The problem with this bit of equipment is simple. Supposedly able to switch between two PCs it does so: intermittently. You cannot (as far as I can see) switch just one of the PCs on by itself and have it work. Except (on two occasions) it has done just that. Most of the time I need to have both PCs on, but when I switch back to one the screen does not show - there is something coming through to the monitor - it's not just "off", but it's just a grey screen because the backlight is on but no-one is home, so to speak. At the moment it's manageable, but at some point I will pick up a better switch. If you would prefer not to spend money twice on the same thing I'd avoid this.

When I ordered this product I was somewhat apprehensive about the quality of it as it due to it being substantially cheaper than other similar products.The delivery time quoted was long but that wasn't a problem, however it arrived a lot faster than expected, so straight away a bonus.I'd previously bought a much more expensive item which, after much messing about and wasting of time, didn't work and had to be returned, so I was hoping for a better experience this time but prepared myself for the worst.As it turned out, it worked brilliantly, just plug and play, just what you always hope for but don't always get.I can have one or two machines on and switch between them easily, the remote button is great as it means you don't need to have all the wiring right by your keyboard or monitor, it can be hidden out of the way.All in all, a good product at a good price with good service. Win, win, win!

Unforunately this device did not work with my setup. I did some research online and I learnt that the video signal is inevitably affected by these switches and it is not guaranteed that the work with every possible combination of devices. There were some recommendation for troubleshooting by changing fundamental settings within the computers but these looked rather scary for me so I just ordered another switch (from a different manufacturer) and luckily that one worked just fine.

I purchased this KVM to allow me to switch between a laptop and a desktop and use the same main monitor and keyboard/mouse. All went well for the first day or so, however, after a period of time when only one of the inputs was powered up I noticed that the monitor would go black for about 1 second every 20-30 seconds. If I powered up the second input to the KVM then it stopped this blanking of the screen.For some reason the KVM only works correctly with two devices connected and powered on...I'm sending this back and will look for an alternative model.
