Nvidia GTX 970: why use 1600x900? Linux opensuse 15.6

hi

first history:
installation opensuse 15.6 with nouveau: works as fine resolution is 1920x1080 with cable DVI…

after months works… but now update opensuse (normal, but i read list of update by opensuse there is MESA-driver, Kernel, new updates…for this thing i was remember maybe will issue with Nvidia…) i update opensuse … reboot system… HERE problem is start with nouveau: display is frozen (mouse is frozen) when i open video or firefox (google map globo 3D) so this is issue with nouveau with Card Nvidia (open driver)…

so now i follow installation driver CLOSE Nvidia (RUN)… i follow guide:
NVIDIA the hard way

installation is works, reboot nvidia is actived and nouveau is disactived… works as fine… but resolution display is 1600x900 , i can’t find 1920x1080…from setting system (kde plasma) also from Nvidia Setting there is not list “1920x1080” until there is 1600x900 …i want to know why? how i will resolve this resolution to 1920x1080 …?

important NOTE:
start BOOT (GRUB2) has resolution:1920x1080
after BOOTING (listing system) resolution:1920x1080
start KDE (X11,Xorg) has resolution:1600x900
i try to change NVIDIA X server settings: has not over than 1600x900, there is not list fields:1920x1080. how my resolution is 1600x900 with cable DVI

BUT i have windows 10, installed last version of Nvidia for GTX970, resolution is 1920x1080 with cable DVI.

but begin: nouveau works resolution 1920x1080 without driver (close)NVIDIA…so i change to (close) driver id Nvidia because nouveau has issue frozen,crash after update kernel…

I don’t understand why linux has not 1920x1080 resolution???

please resolve my pc with Nvidia (close)… maybe i need re-install? maybe i need install driver Nvidia other file of RUN (BRANCH)…?

maybe i need downlad

hi…nothing reply?.. team developers: they don’t read my topic ?
