VGA Boot modes to set screen resolution

A simple way to set your screen resolution and color depth for most Live Linux distro’s is via the use of the vga=parameter boot option. For example at boot you might type: Live vga=795. This would set your system to boot using the Live label with a screen resolution to 24bit 1280X1024. Here are some more examples of common vga boot values.

然后通常在内核参数后以vga=0x0361或vga=788的方式添加

android-x86：

If you want to use higher resolution, you can edit the boot option by pressing TAB, change vga=788 (800x600) to vga=791 (1024x768) or vga=794 (1280x1024), and press Enter. You can also use vga=ask to see all available modes. But please note Android will only work under 16-bit mode.
