Monitor Acer B8 B278U G 27 polegadas Quad HD LCD 2560 x 1440

The Acer B8 B278U G is a 27" Quad HD LCD monitor with a 2560 x 1440 (WQHD) resolution and an IPS panel. It offers a 16:9 aspect ratio, a 4 ms response time and a typical brightness of 350 cd/m². The monitor includes built-in speakers, a USB hub with a downstream Type-C port and supports VESA mounting. Its black finish is suitable for office or home setups where clear image quality and connectivity are required.

Advantages

The IPS panel provides wide viewing angles and consistent colours across the screen. Quad HD resolution gives increased pixel density for sharper text and more workspace compared with Full HD. A 4 ms response time and a 120 Hz refresh rate balance responsiveness for general productivity and smooth motion in video playback. Integrated speakers and a USB hub add convenience by reducing the need for extra peripherals, and VESA compatibility enables flexible mounting options.

Suitable for

• Office work and productivity (spreadsheets, documents, web browsing)
• Photo editing and colour-accurate tasks that benefit from IPS viewing angles
• Multimedia consumption and video playback
• Workstations where external speakers or cable hubs are minimized

How to use

Place the monitor on a stable desk surface or mount it using a compatible VESA arm or bracket. Connect the video source using the appropriate cable (DisplayPort, HDMI or USB Type-C where supported) and connect power. Use the on-screen display (OSD) menu to adjust brightness, colour settings and input selection. If required, connect peripherals to the built-in USB hub and enable audio output through the integrated speakers or an external audio device.

Recommendations

For best colour accuracy, allow the monitor to warm up for 30 minutes before performing colour-critical work and use the OSD controls or a hardware calibrator to adjust gamma and white balance. Ensure proper ergonomics by setting the screen height and tilt to reduce glare and neck strain.
