I purchased a new monitor and I am having problems with the resolution. It is a Samsung SyncMaster S24B150 with an optimal resolution of 1920 x 1080 @ 60 Hz. The highest resolution that I am offered under System/Preferences/Monitor Settings (in Mate) is 1360x768. That is also the only setting that matches a 16x9 aspect ratio. I am using the supplied VGA cable. Do I need to use a DVI cable to get the full resolution? Or is there something else that I can do? Just today I noticed that the image is not using the full width of the monitor. The height seems to be correct. I don't think that it was doing this before, but I don't see any way to adjust it, either through software, or the monitor's menus. The monitor's menus give me the option of 'Auto' or 'Wide'. Using 'Auto' gives me a 4x3 aspect ratio and 'Wide' uses most of the screen, but not all. Again, will getting a DVI cable solve this? Are there drivers that I need to find and install? Any other clues as to what to look for? All help appreciated. Marc
I strongly doubt that it'll help, but maybe your graphical tool lacks features. Try to run "$xrandr" on command line, and it will give you what xorg knows. If you do not find the video mode you want... well, then no other solution than to write a xorg.conf as said by someone else.
