Use the monitor's built-in menu to adjust settings the operating system can't reach

The OSD (on-screen display) is the monitor's own menu system, controlled by physical buttons or a joystick on the bezel or underside, and it's where settings like input source, picture mode, and response time live — none of which the OS can adjust directly.

What you should know

  • Most monitors use either a row of buttons or a single joystick/five-way navigation stick; pressing it typically opens the main menu, with directional movement to navigate and a center press or dedicated button to select.
  • Common OSD sections include: Input Source (switch between HDMI, DisplayPort, USB-C), Picture/Image (brightness, contrast, sharpness, picture mode), and an Advanced or Setup menu with options like response time overdrive, PIP/PBP (picture-in-picture or side-by-side), and OSD language or timeout.
  • A factory reset option is almost always available in the OSD, usually under a "Setup," "System," or "Reset" submenu — useful if picture settings have been changed enough that starting over is faster than manual correction.
  • Some monitors ship with a companion desktop app that mirrors OSD controls over the USB connection, letting you adjust picture mode or input source from the desktop instead of reaching for the physical buttons.
  • If a specific button doesn't seem to do anything, check whether it's a shortcut button (often preset to input source or a picture-mode toggle) rather than the main menu button — these are usually distinguished by a small icon printed near the button.

Why it matters

A meaningful portion of a monitor's functionality — input switching, picture modes, response time, HDR toggling, power-saving timers — lives entirely in the OSD and is invisible to both Windows and macOS, so not knowing how to navigate it means missing out on settings that directly affect image quality and usability.

Best practices

  • Note which picture mode a monitor defaults to out of the box (often "Standard" or "Vivid") since these frequently oversaturate color and inflate sharpness/contrast beyond what looks accurate.
  • Label or remember the input source shortcut button if the monitor has one — it saves a trip through the full menu every time you switch between a laptop and a game console or second computer.
  • Check for a firmware update option in the OSD or manufacturer's app; some monitors fix bugs (flicker, wrong EDID reporting, USB-C compatibility issues) via firmware rather than requiring a hardware replacement.

Common problems and fixes

OSD menu won't open at all
Confirm the monitor is fully powered (not just in standby) and try holding the menu button/joystick slightly longer — some monitors require a longer press to wake the OSD from a low-power state.
Menu navigation is confusing or mislabeled after a language mix-up
Look for a language icon (often a globe or "A/文" symbol) near the top of the OSD's Setup menu, since menu position is usually consistent even if you can't read the current language.

Tips and tricks

  • If a monitor's companion desktop app is available, install it — controlling OSD settings with a mouse instead of a tiny joystick makes fine adjustments like color temperature far less fiddly.

Frequently asked questions

Will a factory reset in the OSD undo Windows or macOS display settings too?

No — an OSD factory reset only affects settings stored on the monitor itself (brightness, picture mode, input source, and similar); OS-level settings like resolution, refresh rate, and arrangement are unaffected.
