Will the SDHN-4D-P switch support a 30-50ft HDMI output cable with signal boost?
Thank you for your inquiry,

You can indeed extend the HDMI output of the SDHN-4D-P KVM Switch with a signal booster.

For video only extension, you can use 1-2 CatX / Fiber based HDMI Video Extenders or HDMI cable Boosters / Repeaters. Two extenders would be required for Dual Monitor.

If you would like to extend the USB for Keyboard / Mouse / CAC as well, you can use a HDMI KVM Extender, like the Rose CRK-1DTXT-HD6, with a second optional HDMI Video Extender for Dual Monitor KVM extension.

If you need 4K resolution support, make sure to pick extenders which support 4K.

For a recommendation based on your application, please feel free to reach out to your KVM Switches Online sales representative.

Also, please let us know if there is anything else we can ever help you with!
