no horizontal sync? screen resolution issues.

i'm running redhat9 on an inspiron 5150, and i would like to be able to change my resolution from 800x600 to something higher.

the cntrl-alt-+ /- doesn't work, and i've been working on changing the settings through redhat-config-x86 but it's problematic.

i know the vertical refresh rate is 60 Hz, and according to dell it does not have a horizontal sync? that sounds rather odd, so does anyone know how to go about this?

thanks a lot!

Welcome to LQ scabies. The command you're running should work, but if it's not, you may be able to find some useful tips in other posts here at LQ about similar situations. You can find those posts through the LQ Search function. Good luck with the project. -- J.W.

i've checked the inspiron 5150 manual before, and it has no mention of a horizontal sync. only a refresh rate of 60 Hz. i've written the company and they have repeatedly told me that my LCD monitor doesn't support "horizontal refresh", or something to that effect.

Try searching dell's web site for bios upgrade for your machine,
they included a fix to many of the x86 communications problems. It did the trick for my inspiron 1100. It was much easier the trying configure the display every time you boot as you do with so of these work around's, but the bios comes as an .EXE so use windows. LOL
