since my resolution is like 800 X 600 i did that i486config and followed the instrutions, but when i rebooted nothing happened.

what is i486config ?? do you mean xf86config ?? you shouldn't have to reboot your system to change the resolution.

tell us the steps you took and what distro, hardware your using and i am sure we could tell you how to change that resolution with ease.

-on my moniter manual it said vertical to be 50 hz to 160 hz so i put in the default range of 40-150. The only reason i didnt add in my correct range was cause i didn't know my @hz.

Im using red hat 7.2, and my video car is an intel 740. my moniter is a samsung sync Master 753 df and i did that xf86 config and i have that file in my home directory. I tried to replace the xf86 file in ect/x11/ with the one i just made but it won't let me, and i tried that with root but it doesnt work for some reason

It is much easier to setup X on RedHat machine using XConfigurator
the command is
Xconfigurator
run it as root in console.
