On most consumer/mainstream motherboards, BIOS only controls the boot/logo/UEFI menu resolution (not Windows desktop). For a 19” AIO with LVDS/eDP panel, the “resolution” setting in BIOS is usually under Chipset → North Bridge / LCD Control.

1) Best resolution for 19” AIO

19″ standard (16:10): 1440 × 900 (most common for AIO/industrial)
19″ wide (16:9): 1600 × 900
18.5″ often: 1366 × 768 (do not use for true 19″)

2) Enter BIOS (AIO/motherboard)

Shut down the AIO.
Power on, then immediately tap the BIOS key:
- Most AIO/industrial: Del (Delete) /F11
- Some: F2, F1, or Esc
You will see the BIOS main menu.

3) BIOS path for LCD resolution (typical AIO)

Use arrow keys to navigate, Enter to select.

Go to Chipset menu
Select North Bridge (or Intel IGD Configuration)
Select LCD Control / LVDS / Display
Choose LCD Panel Type or Resolution
From the list, select:
- 1440×900 (recommended for 19″ 16:10)
- Or 1600×900 (16:9 panel)

4) Save & exit

Press F10 (Save and Exit)
Confirm Yes / OK
The AIO will restart.

5) After boot (Windows)

BIOS sets the POST/boot resolution.
Once Windows loads, set the desktop resolution:

Right-click desktop → Display settings → Resolution → select 1440×900 (or 1600×900).
