The LC-Power LC-M27UO is a 26.5" QD-OLED computer monitor with 4K Ultra HD resolution (3840×2160) and a 16:9 aspect ratio.

Advantages

QD-OLED technology delivers high color fidelity and exceptional contrast with individually lit pixels for true blacks. The 4K resolution ensures precise detail reproduction while the 240 Hz refresh rate and 0.03 ms response time minimize motion blur and input lag. The monitor’s 26.5-inch size balances screen area and desk footprint, and integrated features such as USB-C, built-in speaker and VESA mount support add connectivity and installation flexibility.

How to use

Place the monitor on a stable desk surface or attach it to a VESA-compatible arm or bracket. Connect your PC or laptop via DisplayPort, HDMI or the USB-C downstream port for video and data, then adjust the height to a comfortable viewing position. Use the monitor on-screen display (OSD) to select resolution, refresh rate and color presets appropriate for your task. For gaming, set the output device to 240 Hz and enable any game-related modes; for content work, choose color-calibrated or sRGB/Adobe RGB presets where available.

Recommendations

For optimal image quality and reduced eye strain, use the monitor at native 3840×2160 resolution and 240 Hz where supported. In darker rooms enable darker scene-friendly settings to benefit from QD-OLED deep blacks, and keep firmware and graphics drivers up to date for best performance and compatibility.
