LG 27BA45QB-B 27-inch QHD IPS 75Hz Business Monitor
A 27-inch QHD IPS monitor designed for clear everyday productivity, detailed visual work and comfortable long-session use. The LG 27BA45QB-B combines 2560 × 1440 resolution, HDR10, sRGB 99% colour coverage, 400 cd/m² typical brightness and a fully adjustable stand.
Key Benefits
Detailed QHD Workspace
The 2560 × 1440 resolution provides considerably more desktop space and image detail than Full HD, helping documents, spreadsheets, browser windows and creative content remain clear and easy to work with.
IPS Colour and Wide Viewing
The IPS panel offers 178-degree horizontal and vertical viewing angles, helping maintain consistent colour and image quality when the screen is viewed from different positions.
Strong Everyday Colour
Typical sRGB 99% colour coverage, 8-bit colour and support for 16.7 million colours make the monitor well suited to office applications, web content, presentations and general visual work.
HDR10 Support
HDR10 and HDR Effect support provide additional flexibility when viewing compatible media, while typical brightness of 400 cd/m² helps deliver a clear, bright image.
Smoother 75Hz Refresh
A maximum 75Hz refresh rate provides smoother pointer movement, scrolling and general screen motion than a standard 60Hz office display.
Flexible Ergonomics
The stand supports tilt, height, swivel and pivot adjustment, allowing the display position to be adapted to different desks, seating positions and portrait-orientation workflows.
Made for Productive Workspaces
Clear, Comfortable Viewing
The anti-glare IPS display is designed to keep everyday content easy to view across a wide working area. Flicker Safe and Reader Mode provide additional viewing options for extended document, spreadsheet and browser sessions.
Super Resolution+ is also included for supported lower-resolution content, while Auto Input Switch can simplify changing between connected sources.
Office and Business Flexibility
The 27-inch QHD format provides a useful balance between screen space and desk footprint. A three-side narrow bezel helps create a cleaner appearance and can suit multi-monitor arrangements.
The OneClick Stand simplifies stand assembly, while 100 × 100 mm VESA mounting support provides another installation option for compatible monitor arms and wall mounts.
Connectivity and Audio
Two HDMI Inputs
Two HDMI connections make it possible to keep multiple compatible source devices connected without repeatedly changing cables.
DisplayPort 1.4
A DisplayPort 1.4 input provides an additional digital display connection for compatible desktop computers, workstations and other devices.
Built-in Speakers
Integrated 5 W × 2 speakers provide convenient audio for calls, presentations and everyday media without requiring separate desktop speakers.
Headphone Output
A 3-pole headphone output provides sound output for compatible headphones or external audio equipment.
Useful Display Features
- Dynamic Action Sync helps reduce perceived input delay for supported content.
- Black Stabilizer can improve visibility in darker areas of compatible content.
- Colour Weakness mode provides an additional colour-viewing option.
- Smart Energy Saving provides energy-management functionality.
- Dual Controller software support provides additional control options for compatible systems.
