Screen res. 800x600(4:3) ?

[tekiy]

I want to use 800x600 but I need the wide screen resolution, how do I get it?

that is a very low resolution
system->preferences->monitors

So how do I get 800x600 working correctly?

System->Monitors only gives me 800x600(4:3)
I need the wide resolution (without the 4:3)?
