Looked into hardware..reverted to vesa driver. Set it to sis card and logged out..system complained and went into non-graphics. Went through screen options and eventualy back to graphics and vesa. Had the same problem with debian and a list member after a lot of suffering found a work around in the xorg.conf. After that it works fine. the specific sis card seem to be problemic in some OS's. suse and fedora seem to have no problem. Fedora..could not find a xorg.conf file?. Maybe copy it. If centos resolution problem be not fixable I will have to pass. Would be a pitty. I really do appreciate your time spend to solve this. Regards Johan
