FN Switch¶
Choose what flipping the FN switch does. The switch applies the changes you
pick here all at once, and reverts them when you flip it back. Display options
can be left Unchanged.
Treat it as a quick-toggle profile for whatever you switch between most: a quiet, dim setup for late-night play, turbo fire and a joystick-style D-pad for one particular game, or just LEDs off.

FN mode and the OSD Mute toggle¶
The FN switch and the OSD Mute toggle are separate things.
- OSD Mute is a speaker mute only. It silences the audio output, changes nothing else, and doesn't depend on the FN switch. Press either volume key to unmute; that press also steps the volume.
- Volume when FN is on (below) is part of the FN profile, not the OSD mute.
D-pad stopped moving the menu cursor?
Check Dpad mode when FN is on. Joystick makes the D-pad act only as
an analog stick while the switch is on, so it no longer moves the menu
cursor. Flip the switch back, or set that
option to Dpad or Both.
Volume when FN is on¶
Speaker volume while toggled, 0–20 (Muted for silence).
FN switch disables LED¶
Also turn the LEDs off while toggled.
Brightness when FN is on¶
Display brightness while toggled, 0–10, or Unchanged.
Color temperature when FN is on¶
Color temperature while toggled, 0–40, or Unchanged.
(Hardware-dependent.)
Contrast when FN is on¶
Contrast enhancement while toggled, -4–5, or Unchanged.
(Hardware-dependent.)
Saturation when FN is on¶
Saturation enhancement while toggled, -5–5, or Unchanged.
(Hardware-dependent.)
Exposure when FN is on¶
Exposure enhancement while toggled, -4–5, or Unchanged.
(Hardware-dependent.)
Turbo fire A / B / X / Y / L1 / L2 / R1 / R2¶
Eight separate toggles. While the FN switch is on, the enabled buttons auto-repeat (turbo fire) in games.
Dpad mode when FN is on¶
On devices without analog sticks: Dpad (default), Joystick (the D-pad
acts exclusively as an analog stick), or Both (D-pad sends both inputs at
once). Useful for games that expect a stick.
