nVidia 9500GT wrong resolution

[sasa931]

Hi to everyone!
I installed High Sierra 10.13.5 (17F77) on my old PC but I can't change the resolution from 1280x800 to 1440x900 (my LCD vga/dsub native)...
nVidia Web drivers are installed (last version, 387.10.10.10.35.106) but if I select "NVIDIA Web Driver" instead of "Default macOS Graphics Driver" from the NVIDIA Driver Manager and restart, they go back to "Default macOS Graphics Driver".

What should I do to make this NVIDIA Web Drivers work?

P.s. my mobo have a legacy Bios. Maybe I could solve with enabling NVRAM emulation but I don't know how

...if I select "NVIDIA Web Driver" instead of "Default macOS Graphics Driver" from the NVIDIA Driver Manager and restart, they go back to "Default macOS Graphics Driver".

Ok now I fixed this, "NVIDIA Web Drivers" works.
But the resolution remains low...
