Question: On Smart-AVI's website, this description is shown as - Supports resolutions up to 3840x2160 (@30Hz), not @60Hz as you show it.
Answer: Thank you for your inquiry. We are updating our webpage to reflect the newly available refresh rate information.

Question: Does the display port 1.2 compliance include multistreaming to chain an additional monitor off the first display port connection?
Answer: Thank you for your inquiry,

Multistreaming (MST) is is not supported on the DPN-4PDUO, but may work on certain monitors. The DisplayPort signal is processed along the way so most of the time the datalanes do not have a transparent 1-1 connection. Unfortunately we are unable to recommend a solution with MST as this is not a feature that our vendors support; We would generally recommend avoiding cascading DisplayPort monitors when connected to a KVM - you can achieve multi screen setups over individual video connections.

Question: What is the guarantee period ?
Answer: Thank you for your inquiry. All new Smart-AVI products come with a standard 1 year warranty for defects in materials and workmanship.

Question: If this device is for four PC connections, why are there 8 different input ports?
Answer: Thank you for your inquiry,

SmartAVI DPN-4Duo is designed for switching 4 Dual-monitor PCs - this KVM unit takes in two video inputs as well as 1 USB input from each PC source. For an illustration of this, please see image below:

SmartAVI DPN-4Duo - One source computer illustration

For a 4-port single-monitor version of this switch, please see the SmartAVI DPN-4P.

Question: How would I connect source computers since the cable recommended for this device (CCDPMMKVM-06-S) only has a single (not dual) Dport connection per cable? Please advise?
Answer: Thank you for your inquiry,

This DPN-4Duo KVM would require (1) CCDPMMKVM-06-S + (1) DisplayPort cable (i.e. C2G 54401) per source computer - so a total of 4 of each cable for 4 dual monitor sources.
