Low Grub Resolution

I want to change my grub resolution to 1920x1080.


Tried it already, no success

At the grub screen press c to access the console.

Run this command to display supported resolutions

grub> vbeinfo

Edit you /etc/default/grub and use the desired resolution as the value of


Save the file and rebuild grub

# update-grub

In have changed it to GRUB_GFXMODE="1920x1080" no success

The file /etc/grub/default says

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command 'videoinfo'

So according to this you need to reboot - show the grub menu - holding shift will usually do - then press c and enter the command

grub> videoinfo

Make a note of the supported modes - exit and boot into your system - edit the gfxmode to the supported resolution - they will be applied from left to right - if the mode is supported.

My resolution is not listed...

You can only use supported resolutions.

If it's not listed you cannot use it - use a supported resolution.
