Installation Display
This step (Step 10) asks about your monitor so the installer can pick sensible defaults for both the boot screen and the desktop. There are two parts: the aspect ratio and the resolution.
Pick the shape of your monitor:
- 16:9 (Widescreen) — the most common, covers almost all TVs and modern monitors.
- 16:10 (Productivity) — common on laptops and some business monitors; a bit taller.
- 21:9 (Ultrawide) — ultrawide monitors, good for gaming and multitasking.
- 4:3 (Legacy) — older square-ish monitors.
-
Custom (Enter manually) — type any ratio you like (for example
32:9for a super-ultrawide).
This narrows down the resolution list to only options that fit your screen.
Based on your aspect ratio, the installer shows a list of matching resolutions, plus Auto (Detect from system). If the installer detected actual modes from your hardware, those appear at the top as "Detected: …".
- Choose your monitor's native resolution for the sharpest image (the label shows the common name, e.g. Full HD, QHD, 4K UHD).
- Choose Auto (Detect from system) to let the installer figure it out.
- Choose Custom to type a resolution manually (for example
1920x1080).
Whatever you pick is stored as BOOT_VIDEO_GRUB and reused later in the GRUB step, so your boot menu and desktop share the same resolution.
Tip
If you are unsure, pick your monitor's native resolution or Auto. You can always change it later with retro display or in Settings.
- Kernel & Bootloader — where this resolution is reused for GRUB
- Display & Monitors — changing resolution after installation
