LG 27GL850-B monitor driver installs the display INF so Windows can identify the UltraGear monitor correctly.
27GL850-B driver overview
This driver is a compact monitor package rather than a graphics driver. It helps Windows label the LG 27GL850-B correctly and apply the vendor monitor profile where needed.
When this package helps
- Windows detects the LG monitor as a generic display.
- The LG monitor profile is missing after reinstalling Windows.
- A clean gaming PC build needs the exact monitor INF installed.
Supported Windows versions
Windows 11 / 10 / 8.1 / 7
Before installing
- Extract the ZIP before selecting the INF file.
- Refresh rate support still depends on cable type and GPU driver.
- Use DisplayPort for high refresh rates where the monitor and GPU support it.
