Question: Do you have a switch for 2 PC's sharing 3 monitors, that supports 2 MP? I know the Adder AV4PRO-DVI-TRI-US will (up to 4 MP), but do you also have a less expensive switch that supports 2 MP monitors? Thanks.
Answer: Thank you for your inquiry. Adder also makes a VGA version (, which will support 2MP resolutions including 1600 x 1200.

To discuss other potential solutions, please contact your KVM Switches Online representative by calling 1-877-586-6654 or via our online chat to discuss your project in greater detail.

Question: When will you have this model with USB 3.0 instead of USB 2.0? Also will there be a triple HDMI version with USB 3.0 soon?
Answer: Thank you for your inquiry. Unfortunately, while support for USB 3.0 my be under development for the ADDERView Pro series, we do not believe it will be released anytime in the near future.

We are also unaware of any plans to release a triple-head HDMI ADDERView Pro KVM, but we will absolutely pass along your interest to Adder.

Question: does this work if the video card (quadro k2000) has display port outputs and I use a display port to dvi adapter at the video card end before connecting the dvi cable between the adapter and kvm?
Answer: Thank you for your inquiry,

Adapting your DisplayPort outputs to DVI should be fully compatible with the Adder AV4PRO-DVI-TRI KVM Switch.

Question: Is there any difference between this unit and the Rose multi video dvi unit? They look the same externally. Thx
Answer: Thank you for your inquiry,

Both units appear to be the same based on the casing and features. That being said, internally / functionally the two units may be different even if the units may have come from the same manufacturer.

Question: Is this available in 2 Port? For switching between 2 Triple-head computers.
Answer: Thank you for your inquiry,

The Adder AV4PRO-DVI-TRIPLE is only available as a 4-Port model, but you can always simply plug in two sources, and leave the other two open ports for future expansion.

I am also currently not aware of another similar DVI-based Triple-monitor KVM switch that would be below 4-ports.

Please let us know if there is anything else we can help you with!
