StarTech.com SV211HDUA4K 2 Port HDMI KVM Switch with 4 Foot Built-In Cables - OS Independent - Support for 3.5mm Audio - USB 4K 60Hz (SV211HDUA4K)

Pros: Came complete with cables, some of these switches don't. It worked with my monitor: Acer RT280K bmjdpx 28" 3840 x 2160 (4K) 1ms (GTG) 60 Hz DVI, HDMI, DisplayPort Built-in Speakers LED Monitor The first KVM switch I tried, which claimed to support 4K, did not work. This switch comes with a little button that you can put next to the keyboard, so the box and cables can be hidden, avoiding the cable clutter that you get with these things. I'm very happy.

Cons: I had no problems with this switch.

Overall Review: I have used 2-port and 4-port KVM switches for years. Some units don't switch, some don't work with the monitor, etc. I'm using this with a NUC running Linux and a high-end Windows 10 laptop connected to a high resolution ACER monditor. This unit works like it should.

Pros: -Reliably switches between two inputs to one output just like you'd expect -External button instead of a key combo is important for me

Cons: -RF noise makes my wireless mouse and keyboard very glitchy, I even moved the receiver to an extender closer to the devices but still have issues -A previous KVM I used kept the HDMI "attached" to the computer (a laptop) so my windows stayed on that screen when I flipped inputs. I could see where this might be undesirable to some people because your windows are unaccessible, but I constantly flip back and forth and have to move my windows back to my second screen every time I flip

Overall Review: If you use a wired mouse/keyboard then this product should fit your input switching needs. Wireless devices can get iffy. Use discretion.

Pros: As advertised. Really simple and versatile with the included cabling. The software to toggle between PCs from my Windows keyboard works great (for those without a Scroll key, like me). Before I purchased it, I went online and chatted with their Tech Support group to find out if my monitor resolution would be supported, as the other 2 competitor's boxes did not and were vague about the subject. The StarTech device worked as their team said it would. Took less than a 10 minute chat for them to verify.

Cons: None.

Overall Review: I'd purchase StarTech products again. Never heard of them before, but they exceeded my expectations.

Pros: Easy to set up and use.

Cons: The only issue is with the hot keys. I have to use the button instead. This did not happen with the PS2 VGA switches. Those used the ctrl key instead of scroll lock. Half a switch is better than none.

Overall Review: Go back to the proven ctrl-ctrl hotkey setup. It worked.
