I have my PC running to the LCD tv as well as my normal monitor.

It is connected using a (LONG, in my case) monitor type lead with male end into tv.

Works perfectly.

I use a wireless keyboard and mouse (logitek)
so I can relax on the sofa.

Here is a pic I've just taken of the relevant section from the manual. - might give you an idea as to what to look for.

The faint red arrow points to the female pc socket.

There is also a DVI socket, but I don't think I could get a cable long enough.

Best go and pick someone's brains at Currys before you buy, I reckon.
You'd only need a short lead anyway, presumably....but they can be dear.
