I bought this screen, but the integrated KVM switch does NOT recognise the mouse and keyboard when I connect via HDMI from the screen to my laptop. The image is transferred correctly, but the USB type A (mouse + keyboard plug, which is connected directly to the Samsung screen) has NO power and therefore does not work.
However, if I then connect my business laptop via USB C, everything suddenly works. (Picture + mouse + keyboard).
What could be the problem? I also have a USB C port on my private laptop, but when I try it that way, it doesn't even transfer the image, let alone the mouse and keyboard. The only thing that works is that the laptop charges, i.e. it gets power via USB C. Could it be that something so simple and mundane just does NOT work? Would be incredibly grateful if anyone has any tips so that I don't feel like I'm the only one with this problem again.

Hi, I bought this screen, but when I connect my keyboard and mouse to the screen using usb type a (dock station included) it doesn't work. Can anyone help me? Thanks in advance

Answer

I had a similar problem. The lower (vertical) USB-A port (next to the HDMI port; also labelled "PC") is connected to a PC in my case.This may also be where the power comes from for the two USB sockets in the centre back, into which I have plugged a USB keyboard and a USB Logitech dongle for the mouse. In this setup, the mouse and keyboard work both with the PC and - when the USB-C laptop is connected - with the laptop. Hope this helps.

Answer

Your private laptop needs to support video + USB version 2, 3, etc over the USB C port (USB versions are not the same as connector types). What is the model of your private laptop?
If you connect via HDMI for video and want to use the mouse and keyboard connected to the monitor, then you will also need to connect a USB A to USB B cable connected to the monitor (e.g. https://www.digitec.ch/en/s1/product/delock-usb-a-usb-b-050-m-usb-30-usb-cables-11581392) so that the USB hub in the monitor can be used. Hope that helps.
