Question: Belkin claims 4K resolution at 30 Hz, not 60. Which is correct?
Answer: Thank you for your inquiry,

The Belkin F1DN104P supports 4K UHD (3840x2160) resolution at 30Hz, and 2K (2560 x 1600) resolution at 60Hz.

If you would like a recommendation based on your application, please feel free to contact your KVM Switches Online sales representative.

Question: The manufacturer states 3840 x 2160 @ 30 Hz, not 60 Hz. Which is it
Answer: Thank you for your inquiry. The specifications originally stated 3840 x 2160 pixels (UHD 4K) @ 60Hz, however, it appears the manufacturer has since changed the information.

30Hz is correct for the 3840 x 2160 resolution. We will be updating our page to reflect the new data. Thank you for bringing this to our attention.

Question: This unit shows up under the KVM selector when filtering for USB 3, but it doesn't appear to support USB3
Answer: Thank you for your inquiry,

We have confirmed with the vendor that the USB CAC port on the Belkin F1DN104P is of USB 3.0 standard. Please keep in mind, to qualify as a NIAP-certified Secure KVM Switch, the CAC USB port on F1DN104P (or any secure KVM) is limited to CAC functionality.

If you are looking to use a USB 3.0 peripheral such as an external hard drive with a KVM Switch, you may alternatively want to consider the Avocent SV240D or the Tripplite B004-DPUA4-K.
