�����: But firstly you must understand that the resolution you get when first booting and getting the grub menu may NOT be the final resolution which you will get when you actually login as User into oS. I cannot really explain this difference in resolution but I will just simply state that while my monitor can handle a resolution of 2560x1940 the grub boot menu shows up in (?)1920x1080 resolution.
grub2 relies on video card BIOS, so it can only support resolutions that video card exports via BIOS (probably VESA). You can check it in grub2 using "videoinfo" command (press 'c' in grub2 menu to enter command line).
Ah, I couldn't find the command which gives the resolutions supported by the video card; what you mention may be the one. However, I have one video card (nVidia Geforce (?)550) which shows that 1920x1080 is "not supported" using the check as you suggest above (or something similar which I used [when I did remember what that command was :-) ]) but when oS is installed and the nVidia driver is installed the system runs in 1920x1080 resolution.
The 1920x1080 resolution is set in YaST by configuring the bootloader parameters while the actual monitor's resolution is set elsewhere - but in case with having 1920x1080 resolution you won't have to worry about this. So...... I cannot say where yast gets proposed values (i.e. do they have any relation to real hardware or just hardcoded list of standard VESA modes).
In YaST Bootloader>Bootloader Options one is given the choice of selecting one of multiple VESA resolutions. In 13.1, 1920x1080 is now a choice whereas it wasn't a choice prior to (?)13.1.
