Hai,
I want to connect one more monitor besides my PC monitor for remote application. Presently I am using a VGA card from my PC for connecting another monitor. Can I use a HUB and a 8051 device for replacing this VGA card? Any one can give me an opinion on this regard?
This shows the kind of thing that is practical with an 8051:

You will see that it is nowhere near a VGA display - and no ethernet.
Maybe you should start with a simple project like this - then, once you understand the issues, you will be better placed to think about what would be involved in your "full" requirement...
