The SM-UHN-4D-S was once known as the UHDN-4P-DuoS
Question: Can this KVM support HDMI 2.0a and therefore transmit an HDR 4K source? Thanks
Answer: Thank you for your inquiry. I have confirmed with SmartAVI that the UHDN-4P-DUOS does support 4K HDR signals via HDMI 2.0a
Question: Does this support Bluetooth keyboards via a USB Bluetooth Adaptor?
Answer: Thank you for your inquiry,
Using Bluetooth keyboards and mice with a KVM is hit or miss. This is related to the very different way in which Bluetooth peripherals communicate and a KVM's internal mouse/keyboard emulation. Since KVM vendors do not explicitly state support for wireless peripherals, we are unable to guarantee a particular Bluetooth setup will work with a particular KVM - For the best performance, we always recommend using a basic, cabled keyboard and mouse.
That being said, we have customers who have had success in using Bluetooth devices by plugging the device into one of the USB Hub ports rather than the USB Keyboard port. In this case, you will likely need to use the push-buttons on the UHDN-4P-DUO rather than hot-key combinations for switching. This configuration may also lead to some loss in some functionality such as the keyboard emulation.
Question: Is this switch operating system agnostic? I have to switch between different versions of Linux and Microsoft Windows operating systems.
Answer: Thank you for your inquiry,
The UHDN-4P-DUOS is a plug-and-play device that does not require any separate drivers - this switch is operating system agnostic and should work on any version of Windows or Linux.
Question: Does this KVM switch also allow for split mode where you can display PC1 on Screen 1 and and PC2 on Screen 2?
Answer: Thank you for your inquiry,
It would not. Your best option for being able to switch between source computers on 2 separate screens - almost like two KVM switches, but controlled by one keyboard and mouse - would be one of the following:
1) Use a Command Center (Keyboard and mouse) switch i.e. Adder CCS-PRO4. CCS-PRO4 supports multi-monitor setups, and would let you display PC1 on screen 1 and PC2 on screen 2 while i.e. dragging a mouse to switch between them.
2) Multi-User KVM-Over-IP switch i.e. AVX4016IP or a multiple KVM-Over-IP gateways would allow you to open up any of the connected source PCs in individual browser windows which you could move around (i.e. have window 1 with PC1 on screen 1 and window 2 with PC2 on screen 2).
If this is not quite the solution / application you were looking for, or you would like to further discuss your application, please feel free to contact your KVM Switches Online sales representative directly.
Question: Does the UHDN-4P-Duo support 4K 60Hz RGB(YCbCr 4:4:4) 10-bit?
Answer: Thank you for your inquiry,
While it does support 4k60 RGB, it only supports the 8 bit variant.
For a KVM that supports 4K 60Hz RGB(YCbCr 4:4:4) 10-bit, you may want to consider the Aten CS1944DP Dual-Monitor DisplayPort KVM as an alternative.
