Try use the onboard DP video port instead of VGA.  If does not work, install a simple video card.

You can also try to update the video card driver. That might work.

Intel(R) HD Graphics Driver was the issue, once disabled,  "Display resolution" is back to normal. 

Now the problem is, My CapCut video editor requires to enable the Graphics driver, so I enable the driver and the resolution issue is back. The only way I can avoid Intel(R) HD Graphics Driver is to roll back to previous installed driver which is Microsoft Basic Display Adapter, now everything is working fine for the moment, hoping that Intel(R) HD Graphics Driver won't auto update.

@redxps630​ It's Intel HD Graphics drivers that's causing the problem, I uninstall Intel driver and I was able to select my preferred resolution, but in just a moment the Intel driver was installed automatically, so I disable Intel driver and now I'm able to select my resolution again. This seems odd though,  what do you think?
