I am not sure what that means.

I'd like to add detailed resolutions for 640x480, 800x600, and 1024x768, with high refresh rates. I am using a Windows 10 machine with a gtx 770. I have the monitor connected to the video card using a vga cable (from the monitor) and a vga/dvi adapter plugged into the video card's dvi-A port.

Is there something I should be aware of before doing this (e.g., can I risk damaging the monitor?). Any advice?

Usually monitors with an on-screen menu will refuse to display any resolutions that are out of supported range, so there should be no problem as long as you stay within the supported frequency range. CRT monitors are usually limited by the horizontal frequency. Horizontal frequency is just the total number of lines per second including blanking as shown in CRU.
