Re: [Trisquel-users] Achieving native 1680x1050 resolution in Syncmaster 2253BW monitor

Again, you do not have an nVidia card. You have a "S3 Graphics" that simply  
may not support such a high resolution (did you search its technical  
specifications?). If it actually does, then the Linux driver does not and,  
given the popularity of the brand, it is extremely improbable that an  
alternative driver exists.

In the end: either you acquire another card (an old nVidia card would be a  
good option) or you settle with the low resolution.
