Blank screen with resolution error after installation

I have 40 of HP SL165S G7 to install Rocky 8.5. I plan to use them as a computation cluster for genomics. I found OpenHPC useful for the management of cluster. Finally I decided to install Rocky and OpenSUSE according to the list of OpenHPC OS recommendations. I tried Rocky 8.5 first. Rocky install screen did not come up and I tried to edit boot with vga=319, it worked. After installation finished and restarted, even I changed the grub, screen goes blank and gives the error to change the resolution. How can I overcome this problem? I tried different monitors, no luck.

Can I make install and post-install screen size 1280x1024?
