Ah, yes, sorry. I assume you are using grub2, which is default on void. In 
that case you need to do the following:

   1. Reboot
   2. When your grub menu comes up press C to enter the console
   3. Run "*vbeinfo*". That will give you a list of supported resolutions. 
   Note down one you like, for example "1024x768x32"
   4. Run "*reboot*" and boot into your system
   5. Edit the file */etc/default/grub*, uncomment the "*GRUB_GFXMODE*" 
   variable and set it to the resolution you noted down
   6. Run "*update-grub*"
   7. Reboot

Now you should have a different resolution in your console
