I've been asked by another wammer to lay out some instructions regarding VNC servers/clients.
I use my smartphone as a remote control for my PC by using VNC software which basically uses the IP address of your desktop pc or laptop even, and displays your session on the screen of your tablet/phone of choice.
I don't know all the techy stuff, but basically, first you need to install a vnc server on your pc. Theres a few different ones out there, but I've used one called " tightvnc " which is available HERE
Next you need to install a vnc client on your phone/tablet. I use an android device and went for free bvnc which is available on what is now called Play Store, ( the old Android "Marketplace" )
When you open the free bvnc on your phone, you have to pop in the ip address of your pc, and the password (if you set one up when you installed the server on your pc), and when you click connect you should see your desktop screen appear on your phone etc. You can use your fingers on the screen to navigate your way around and if you need to scroll, 2 fingers on the screen and drag up or down.
I hope I've explained that well enough, I'm usually shite at explaining things, but any questions, I'm sure if you post here, me or someone will help out.
