Higher resolution means more text in the same window this especially applies to the console. The following was tested in Debian 7 Wheezy and Ubuntu 13.04. With Grub 2 with can easily increase the resolution by making a few changes.
Open and edit the grub file.
Search for the following line and uncomment “#GRUB_GFXMODE=640“, modify it to include a higher resolution such as 1440×900. Also add the line “GRUB_GFXPAYLOAD_LINUX=keep“.
The lines above should be what increases the console resolution.
Now update Grub.
And restart the system.
sudo shutdown -r now
Now you should be able to make better use of your monitor resolution.
