 2 Port VGA KVM Switch, Yinker Desktop USB VGA KVM Console w/ 2 KVM Cables & 3 USB Hubs Support wireless keyboard & Mouse and USB devices  

Pros:

The highlights for this USB VGA KVM switch are 2in1 KVM cable (USB A & VGA to VGA) and one additional USB port for 2 computer to share U disk or printer. it can also share USB speaker for both computers.

Cons:

- The upgraded KVM cable sometimes are wrongly plugged. I do think they should clarify in the description. Yinker is a professional KVM brand, available for 2-port , 4-port, 8-port, 16-port,  and KVM Cable series.

Conclusion: it's worthy

Pros:

This is a 2-port USB HDMI KVM switch. For 4K 30Hz HDMI KVM, this one is the best choice with good looks, upgraded 2in1 USB HDMI KVM cables included, and one USB port for U disk or printer for 2 computers, and a wired desktop selector, price around 25$.

Cons:

it product beep when switching. if you don't mind the beep, it's good.

Yinker also supply other HDMI KVM for 2 port , 4-port, 8-port, and KVM over Cat series.

 
 

Pros:

This 2 port KVM is described as 4K 60Hz, but I do think it's 4k 30Hz as it can only support RGB 4:2:0, means only compatible partial machines.

Cons:

- Honestly, this 4K KVM switch looks very nice, but it's not built with other USB hub for U disk or printer. And it's the old version, connected by one 2 USB cables and 2 HDMI cables( not included), can't share USB speaker for both PCs

 
 
 

Pros:

This 2 port HDMI KVM supports 4K 30Hz. As I know few models supports hotkey switch, so this one is good.

Cons:

- it's old version with twin ports and twin cables (HDMI & USB A to B). No additional USB hub for U disk or printer, can't share USB speaker for both PCs.

 

Pros:

In fact, this is not a KVM. It's a USB3.0 switch,. I don't know why it's described as KVM switch, obviously misguiding. This USB switch allows 2 computers to share 4 USB ports. Cons. it's not built with video port like VGA/HDMI, can't share one monitor for both computers
