Hi

Keyboard and mouse have no connection with Monitor
Since keyboard and all are linked with mother board

so firstly i suggest you yo check the wireless connections are ok

Now reinstall the software packages that came with the keyboard(And drivers)

i hope this will help you

you need to resync the mouse and keyboard to the wireless receiver. you hold the button down on the receiver until you see a flashing light and then you press the button on the bottom of the key board. then you do the same thing for the mouse.

I can't find a users guide but I did find drivers based on your model number. Once the drivers are loaded it will walk you through setting up of the mouse and keyboard and have a help section. Download software and install. Pick the correct operating system. Hope this helps.
