Description

The Acer B278U E 27" UltraWide Quad HD LED 2560 x 1440 is a 27-inch IPS monitor with a 2560 x 1440 resolution and 16:9 native aspect ratio. The LED-backlit panel delivers a typical brightness of 350 cd/m², a typical contrast ratio of 1000:1 and a fast 4 ms response time. Wide 178° horizontal and vertical viewing angles ensure consistent colour and image quality from different positions.

Advantages

The IPS panel and UltraWide Quad HD resolution provide detailed, consistent colour reproduction and sharp imagery suitable for content creation, office productivity and general multimedia. The 4 ms response time and LED technology reduce motion blur for smoother video and casual gaming. Built-in speakers and standard VESA mounting add convenience for different desk setups, while height adjustment supports more comfortable long-term use. Energy consumption figures are specified for SDR and HDR usage to help estimate operating costs.

How to use

Place the monitor on a stable surface or attach it to a VESA-compatible arm or bracket. Connect the video source using the appropriate cable supported by your computer or device. Adjust the screen height and tilt to achieve a comfortable viewing angle and position the monitor so the top of the screen is near eye level to reduce neck strain. Use the on-screen display (OSD) controls to set brightness, contrast and colour presets for your environment. If using the built-in speakers, connect the audio output from your device or enable audio over the video connection.

Usage recommendations

For consistent colour-critical work, allow the display to warm up for at least 30 minutes and use calibration tools or software. Keep the monitor firmware and graphics drivers up to date. To reduce power use, select appropriate power-saving settings and lower brightness when possible. When mounting on an arm, ensure the VESA mount supports the monitor weight and that cables are routed to avoid strain.
