No.

No. NIAP regulations forbid the usage of USB hubs and they have been blocked in the KVM. This block cannot be removed. When connecting a USB hub the status LED next to the USB port you are connecting to will illuminate red to show the hub has been blocked. 

Ultrawide display support requires the use of the F1DN2MOD-HC-S06 Dual DP++ MST Host Cable from the KVM to the host computer.  

Yes, but it is recommended that you check with your dock manufacturer for any required software and firmware updates first. Also check with your dock manufacturer regarding monitor and resolution support to ensure that your dock will support your displays. 

No. Belkin’s Modular Secure KVM Switch PP4.0 support HDMI, DisplayPort and DVI video inputs, and output as both HDMI and DisplayPort connections. This allows you to input and output as either type of signal with the KVM handling the conversion. 

Belkin Secure KVM’s support basic USB keyboards right out of the box. Keyboards with additional functionality such as hot keys and multimedia keys may not function unless used with a Belkin HID Filter F1DN-HID-FLTR Keyboards with built in CAC card readers or USB hubs are not supported at all and will be rejected by the KVM’s security settings.

The Caps Lock, Scroll Lock and Number Lock keys on your keyboard require two-way communication between your keyboard and computer. For security, the KVM blocks these communication paths, which causes your keyboard to not illuminate when these functions are activated. Your Belkin Modular Secure KVM Switch PP4.0 features status LED’s on the top which illuminate to show these functions are active for the current channel. These are a per-channel illumination, and the KVM remembers the active status when switching. 

Ultrawide monitors are compatible with the Belkin Modular Secure KVM Switch PP4.0 as long as the resolution specifications are under the 4K @ 30Hz maximum.  The F1DN2MOD-HC-S06 Dual DP++ MST Host Cable is required to connect the computer to the KVM for ultrawide monitor support. 

No. The buttons on the KVM and Remote are only white LED’s. You can set custom channel colors when using the Belkin F1DN008KBD KVM Remote Control with Integrated Keyboard. 

No.  

The most common reason for no video is improper power up of the KVM. Belkin Modular Secure KVM Switch PP4.0 looks for display connections immediately upon power up. If it does not detect a displaly then no monitor information will be sent to the computer. The KVM should be powered off and then connect the displays. Power on the displays and choose the input connected to the KVM. After this power on the KVM. The EDID lights should be solid green within 10 seconds. If these are not solid green then the KVM is not detecting your displays and you will need to perform other troubleshooting. 

The Belkin Modular Secure KVM Switch PP4.0 does not support adaptive refresh rates. For the best and most stable performance it is recommended to disable FreeSync and G-Sync in both your display and graphics settings before using the KVM.  

Belkin’s Modular Secure KVM Switch PP4.0 support only one method at a time for changing channels. The default method is the buttons on top of the KVM but if you are using either the included modular remote or the F1DN008KBD KVM Remote Control with Integrated Keyboard, the KVM will disable the top buttons and use these instead. 

No. The Belkin Modular Secure KVM Switch PP4.0 supports only 1 remote control at a time. Using both can cause functionality issues.
