Resolution option is limited

Hi there, I am new to learn Rocky Linux 9.4. Currently I am dual boot OS that include Rocky Linux 9 and Window 11. Once I boot up my Rocky Linux, there resolution is by 800x600 (4:3) and there is the only option. Maybe I know what is the problem for me to choose resolution scale?

Where exactly are you seeing this?

It can be combination of video card, driver, cable and monitor.

I’ve had a similar problem, though it may be from a different cause. Please could you run
lspci -nn | grep VGA
and tell us the resulting output ? If there is no resulting output, then your cause is different from mine; if there is output, it will help me know whether or not your cause might be the same as mine.
Thanks, Roger.
