Hi Jeff Thanks for the reply.
I have an nvidia card (mx440) in this PC. Tried comparing xorg.conf between Fedora 8 and Kubuntu/LinuxMint but it appears that Fedora 8 has a different method of using xorg.
As a result of email from Rev Rumble I eventually installed LinuxMint 4 ( gnome Livecd) - I had Mint 2.2 installed - and installed "restricted" nvidia drivers and after using monitor controls all is almost well ( desktop just a fraction too far right) and I get 1680x1050 at60hz .
