depends on your hardware but yes you can have an aditional Monitor

but im not sure how far your wireless mouse can reach.

Your going to have to run RCA cables to your PC. At the club we have all our computers in our amp room about 30 feet away. We have A KVM extender that works over Cat 5. There is a sending module that connects to the USB of the computer & the monitor out. From there we have a cat 5 cable run to the DJ Booth. The recieve end in the booth has two USB plugs (1 keyboard, 1 mouse) and a monitor plug. Works great... That may be an option as well.

The KVM Extender could be a good option, I'll do some research and find out more as I don't know much about this... Thanks Robinson.

My home setup is just an LCD on the wall with a wireless mouse... its run from my laptop a distance away. So yeah its definitely possible and I would recommend it, but just make sure your wireless mouse works the distance as mentioned above.

I considered doing this when I got my Serato, but I didn't have the wireless mouse and keyboard, so I decided to spend £100 on a new PC. That way I have a clean build of Windows dedicated to running Serato, and I've got no worries about batteries running out or noise picked up on long cable runs.

This sounds good then, I checked my mouse last nite & it works thru the wall fine!

So, by looking at the diagram I would just need a long usb cable. Is this correct?

Cheers.

and a long vga cable for your monitor, unless you have a work around for that

The maximum recommended cable length between a USB computer and USB interface is 5 meters (16.5 feet).

I'd say you could run in to problems using a long USB cable, you might be better using long RCA cables, just make sure they are good quality to stop them picking up noise.
