MPN #: DELL-U3225QE
Tired of blurry spreadsheets and sore eyes after a long day at the desk? The DELL UltraSharp U3225QE eliminates guesswork with true 4K clarity and eye-comfort technology. You get a 31.5" screen that shows every detail, while ComfortView Plus and a 3000:1 contrast ratio keep fatigue low. In one package you also gain fast 120 Hz refresh and a full set of ports, so you can work, design, or stream without compromise.
This 31.5-inch LCD monitor is built for professionals who need accurate colors and plenty of screen real-estate. Whether you edit photos, code, or run multiple apps, the 4K IPS panel delivers consistent brightness and wide viewing angles, while the detachable stand lets you adjust height, tilt, swivel and pivot to fit your workflow.
