AOC 90 Series U2790PQU 27" 3840 x 2160 pixels 4K Ultra HD LED Monitor Black
Many users need a single screen that can show fine detail and accurate colors, yet most monitors either lack resolution or force you to buy multiple displays. Missing detail can lead to mistakes in design, missed data in spreadsheets, and a less enjoyable movie night. The U2790PQU solves this by delivering true 4K resolution on an IPS panel, wide color coverage, and ergonomic adjustments so you can work comfortably for hours.

- Sharp 4K image lets you see every pixel, perfect for photo editing and detailed spreadsheets.
- Wide 108% sRGB coverage means colors look true, helping designers create accurate work.
- Low Blue Light and Flicker-Free technology reduce eye fatigue during long sessions.
- Ergonomic stand with tilt, swivel, pivot and height adjustment lets you find the most comfortable viewing angle.
- Built-in USB hub reduces desk clutter by letting you plug peripherals directly into the monitor.
Usages
The U2790PQU fits a home office where you need a clear view of spreadsheets, a graphic studio that demands color accuracy, a gaming setup that benefits from a smooth 60 Hz refresh, and a media corner for streaming 4K movies. Its VESA-mount compatibility also lets you attach it to a wall or an arm for a clean workspace. Whether you are a freelancer, a corporate employee, a student, or a casual gamer, the monitor adapts to your daily tasks.
