4K HDMI KVM Switch, 4 Port HDMI USB Switch for 4 Computer Share a 4K@30Hz Monitor and 3 USB Device Keyboard Mouse Printer, Including 4 KVM Cables

I had been using my TrippLite VGA KVM for years and putting up with a pretty terrible picture for such a long time. Finally after realizing nearly all my regularly used machines had HDMI natively, I ditched all the VGA cables and dongles and this little generic (model HK401, no brand name at all) arrived today.The improvement in video quality when using this KVM was IMMEDIATE. I’m so pleased with this thing and it was very reasonably priced (under $60). It’s so small I couldnt even believe it was a 4 device KVM, but here it is driving 3 PCs of mine, 2 Macs, one Linux and one I use for when my laptop is upstairs, and it works amazingly, no issues. Audio passes through to my monitor for the active device, meaning no more need for an external pair of speakers. So much less clutter on the desk now.Pros:- it’s tiny! You can see in the first picture how it compares in size to my old TrippLite KVM.- No external power supply needed. Another win for this device that I didn’t even realize I wanted. Grabs power from the device(s) you are controlling, and has no problem powering my keyboard with backlight and optical mouse.- Less expensive than other HDMI KVMs I’ve looked at and much less than my old VGA one.- Provides an incredible picture at least compared to my previous VGA KVM.- Love the controller cables, obviously they are some proprietary format with HDMI on one end but on the other is both HDMI and a USB port. Cables feel sturdy but flexible and I like the greenish/cyan color.Cons (not many, but a few)- When pushing the button to switch inputs on the unit it sounds a little hollow. A very minor nitpick.- I’d probably prefer it to be a little bigger actually, if it means all the cables could be on one side (i.e. the back). As it is, the HDMI ports are one of the long sides of the unit, and the USB inputs are on the other. I ended up just placing it on my desk sideways until I tidy it up the cables more (second picture). Or maybe I’ll leave it as is.- Finally, I do wish it came with an HDMI-HDMI cable to connect up to the monitor. Presumably they assume you’re already using at least one HDMI device, I’m probably a pretty odd case in that I was not.Overall though I’m very happy with this purchase, whatever company made it should stamp their name all over it because they made one great product!
