Does this support having one DisplayPort input drive both HDMI outputs, or does the input have to use both ports?
Thank you for your inquiry,

The SmartAVI D2H-4P-Duo would need both DisplayPort inputs plugged in for dual monitor support - It does not support DisplayPort Multi-Stream-Transport (MST). Currently (10/18/2016), the only DP KVM that I am aware of that supports MST is the 2-Port Aten CS782DP.

If you have any questions about MST, or would like a recommendation based on your application, please feel free to contact your KVM Switches Online sales representative directly.

I thought HDMI was limited to 2560 x 1600 resolutions. Does this KVM actually provide 3840 x 2160?
Thank you for your inquiry,

HDMI version 1.4, which features a bandwidth of up to 10.2Gbps, introduced the ability to deliver 4K video of 3840x2160 @30Hz. This SmartAVI D2H-4P-Duo is indeed able to provide 3840 x 2160 (30fps).

HDMI version 2.0, which features a bandwidth of up to 18Gbps, introduced the ability to deliver full 4K video of 3840x2160 @60Hz. You may also be interested in the SmartAVI UHDN-4P-DUO HDMI to HDMI KVM switch which can provide 3840 x 2160 (60fps).

How does it support audio?
Thank you for your inquiry,

The SmartAVI D2H-4P-Duo supports stereo audio sharing over a separate 3.5mm audio connector; Each of the 4 source inputs has a 3.5mm stereo audio port that you can plug in an audio source to, and the user console section also has a 3.5mm stereo audio port for output.

The picture does not match the picture in the referenced manual. The manual shows audio ports on the back but the picture here does not show any audio ports.
The new versions of the D2H series including this D2H-4P-Duo do indeed have audio ports on the back. We have updated the images on this page to reflect that feature.
