Default Re: Request for new Sticky about resolution issue!

Hey Paul,

Here's a big Thank you!

I just spent a day and a half trying to figure out why I couldn't get my new LCD monitor, when connected with the DVI cable, to work with its native resolution of 1680x1050.

After searching, hacking and borking xorg.conf to no end, I happened on the post where you linked to this one.

At first I was stuck with 1280x1024 resolution which, through nVidia's configuration setting, was listed as the native resolution for this monitor.

I was able to sneak up to the proper resolution by adding this line to the Device Section...

Option "ModeValidation" "NoDFPNativeResolutionCheck"

which at least got me to 1440x900. Close but no cigar and nVidia setting were still listing 1280x1024 as the monitor native resolution.

Finally your suggested...

Option "ModeValidation" "NoMaxPClkCheck"

got me to 1680x1050 and now the nVidia configuration setting also list 1680x1050 as the monitor native resolution.

BTW, my card is a FX5500 and all the modelines generated by gtf were left as they were when initially setting up the nVidia drivers (100.14.19) and not messing with any EDID options. Even with the 147.14 pixel clock settings for 1680x1050@60.

Therefore, I second the request for a sticky.
