For the vttys, it's pretty simple. If your display is 3840x2160, try adding to Grub stanza's linu line one of the following video=2560x1440 video=2048x1152 video=1920x1080 If it's 2560x1440, try one of video=2048x1152 video=1920x1080 video=1600x900 If it's 1920x1080, try one of video=1600x900 video=1280x720 Use xrandr in an X11 terminal to determine resolutions supported by your display. <https://www.kernel.org/doc/Documentation/fb/modedb.txt> If your GUI is employing the intel driver from xserver-xorg-video-intel, it may inherit the kernel cmdline's video= resolution. Whether it's possible to change on an already booted system, I have no idea.
