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.<br /><br />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.						</div>						<div class="kwm-qa-helpful">							100% of 1 people found this helpful.

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: <br /><br />1) Use a <a href=\'https://www.kvm-switches-online.com/keyboard-mouse-switch.html\'>Command Center (Keyboard and mouse) switch</a> i.e. <a href=\'https://www.kvm-switches-online.com/ccs-pro4-us.html\'>Adder CCS-PRO4</a>. 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.<br /><br />2) <a href=\'https://www.kvm-switches-online.com/kvm-switch-over-ip.html\'>Multi-User KVM-Over-IP switch</a> i.e. <a href=\'https://www.kvm-switches-online.com/avx4016ip.html\'>AVX4016IP</a> or a multiple <a href=\'https://www.kvm-switches-online.com/kvm-over-ip-gateways.html\'>KVM-Over-IP gateways</a> 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).<br /><br />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 <a href=\'https://www.kvm-switches-online.com/contact-us.html\'>contact your KVM Switches Online sales representative directly</a>.<br />						</div>						<div class="kwm-qa-helpful">							0% of 0 people found this helpful.
