LG UltraGear 27GN950-B Monitor Driver for Windows

The LG UltraGear 27GN950-B is a 27-inch 4K Nano IPS gaming monitor. This local LG archive is the model support package used when Windows needs the correct monitor identity and profile instead of a generic PnP entry.

LG UltraGear 27GN950-B driver overview

Installing the monitor INF does not by itself unlock 4K at 144 Hz. That also requires a compatible graphics card, current GPU driver, Display Stream Compression support and the correct DisplayPort connection. The page keeps those roles separate so a small monitor package is not mistaken for a full display driver.

When this monitor package helps

• Windows lists the display as Generic PnP Monitor instead of LG UltraGear 27GN950-B.
• The correct color profile is missing after Windows was reinstalled.
• Device Manager needs the signed monitor INF before display settings are checked.

Supported Windows versions

Windows 11 / 10 (64-bit).

Before installing

• Check the exact 27GN950-B suffix before installation; nearby UltraGear model numbers are not interchangeable.
• Extract ZIP or CAB packages before choosing the INF file in Device Manager.
• The graphics-card driver remains separate and should be installed for resolution, refresh-rate and GPU features.

Compatibility notes

This entry is intended for the 27GN950-B and current 64-bit Windows systems. LG sells closely related 27GN95B and 27GP models, so compare the full model number on the rear label before installing. OnScreen Control and monitor firmware are separate downloads and should not be substituted for the INF package.

Common installation checks

• If Windows says the best driver is already installed, use Have Disk and select the extracted model INF directly.
• If the exact model is still missing, reconnect the video cable and remove only the Generic PnP Monitor entry before scanning for hardware changes.
• If refresh-rate or HDR options are absent after the monitor INF is installed, update the graphics driver and verify the cable and input port.

Questions about this driver

Is a monitor INF the same as a graphics driver?

No. The monitor package supplies the model identity, supported timing information and usually a color profile. NVIDIA, AMD or Intel separately supplies the graphics driver.

Can Windows work without this package?

Usually yes, through Generic PnP Monitor. The model-specific package is useful when you need the proper display name, signed INF data or the manufacturer's color profile.
