## Long description

The Acer UM.GXXEE.303 27" OLED 2560 x 1440 is a 27-inch OLED monitor offering a Wide Quad HD (2560 x 1440) native resolution on a flat 16:9 panel. The display uses OLED technology to deliver high native contrast (typical 1,500,000:1) and fast pixel response (0.03 ms), supported by wide 178° viewing angles horizontally and vertically. The monitor includes built-in speakers, an integrated USB hub with a USB-C downstream port, VESA mounting compatibility and height adjustment, all in a black chassis designed for desktop and workstation setups.
Advantages
The OLED panel provides deep blacks and high contrast for accurate image reproduction, while the 2560 x 1440 resolution balances detail and system performance. A very low 0.03 ms response time reduces motion blur for fast-moving content. Built-in speakers and a USB hub reduce cable clutter, and VESA support with height adjustment enables ergonomic placement. Typical brightness of 275 cd/m² and a compact pixel pitch (0.229 x 0.229 mm) help maintain sharp visuals for text and graphics.
Suitable for
Photo and video editing where high contrast and accurate blacks are required
Content consumption and streaming with wide viewing angles
Office and productivity tasks benefiting from a 27" 1440p workspace
Light gaming and fast-paced media thanks to 0.03 ms response time
Multi-device setups using the built-in USB hub and USB-C downstream port

How to use
Place the monitor on a stable desk or mount it using a VESA-compatible arm or bracket. Connect the display to a video source via DisplayPort or HDMI if available from your system, or use the USB-C downstream port for video, power delivery and data if your device supports it. Adjust the height to set the top of the screen at or slightly below eye level for ergonomic viewing. Use the on-screen display (OSD) menu to set brightness, color mode, and input selection. Connect peripherals to the built-in USB hub and route audio through the integrated speakers or an external sound system as needed.
Usage recommendations
For color-critical work, allow the display to warm up for at least 30 minutes and use a colorimeter for calibration. Keep firmware and graphics drivers up to date to ensure best compatibility and performance. Avoid prolonged static high-brightness images to reduce the risk of OLED image retention; use screen savers or vary content when the monitor is idle.
