Question: Would this product be able to take four xbox 1 hdmi video inputs in. And one hdmi out to a capture card that is streaming from a computer to a live stream website. Would it be able to switch without any signal interruption in the output and the input hdmi sources?
Answer: Thank you for your inquiry. This device is primarily for controlling HDMI based computers and may require a keyboard and mouse to operate. We are also not familiar with how any digital rights management would function under the above scenario. For the most part, switches of this nature will have at least some signal interruption, even if for only a half second.

You may be interested in a dedicated HDMI switch like the following device: https://www.kvm-switches-online.com/hr-4ps.html. Of course there may still be digital rights issues with the video capture.

Question: Will this product support 2 monitors with a HDMI spliter?
Answer: Thank you for your inquiry,

Using a HDMI splitter with the HKM-PROS will provide the ability to output two identical signals to two seperate monitors. If you are looking for a true dual-monitor KVM, please refer to our Dual-Monitor KVM page or our Dual-Monitor HDMI KVM page (not many vendors offer dual monitor HDMI).

If you would like a recommendation based on your setup, please feel free to contact your KVM Switches Online sales representative directly at 1-877-586-6654, at sales@kvm-switches-online.com, or via our online Chat functionality.

Question: Does it include cables?
Answer: Thank you for your inquiry,

HKM-PRO-S package contents includes: (1) HKM-Pro KVM and (1) PS5VDC4A power adapter. The cables are sold separate; you can find a links to HDMI, USB, and audio cables page under the accessories section of this HKM-PROS page.

Question: Hi - I am looking for identical unit that will handle 8 devices. I have five right (Raspberry PI computers) but having eight ports will allow a little flexibility to add on. Thanks
Answer: Thank you for your inquiry,

While SmartAVI does not sell an 8-port vesion of the HKM-PROs, they do sell a similar 8 port HDMI KVM switch: SmartAVI HDN-8P-S.

For a KVM recommendation based on specification in your application, please feel free to contact your KVM Switches Online sales representative directly.

Question: Does the unit switch automatically when you add a new computer or can it be controlled completely manually? The goal is to have it where I plug in a computer and it does NOT disrupt the video from the machine I have selected.
Answer: Thank you for your inquiry,

According to the vendor, the HKM-Pro is not hot pluggable. It is best to have it switched off when you are plugging in or swapping sources.

For a Hot-Pluggable KVM switch solution for your application, please feel free to contact your KVM Switches Online sales representatives.

Question: Is it possible to disable any of the ports on this KVM?
Answer: Thank you for your inquiry,

While disabling the full port is not currently supported by the HKM-PROS, It is possible to disable USB Hub or Audio "auto-switching" to prevent audio and USB peripheral media devices from being switched when switching sources.

We do also have some managed matrix systems, such as the AdderLink INFINITY, which do support disabling source ports via user rights management.
