I have used logmein.com which is freaking amazing. You can scale resolution, transfer files, and connect to multiple pcs. They have a free service which u can register for at logmein.com. It requires you to install a client running on the pc you want to control and then just go to straight to the logmein.com website on your phone. it also installs a client on your phone and there ya go.

I use it to connect to my media server and home, and to fix peoples computers I have it set up for.
