QD-OLED Ultra-slim Design
The S2721BO features a Samsung QD-OLED self-luminous panel, unlike LCDs that require a backlight, providing a thin and light display. Quantum dots that emit light by themselves can deliver vibrant colors, precise light control, and stunning image quality.

Self-Developed Cutting edge Panel Protection
The monitor has an independently developed OLED protection mode featuring pixel shift, pixel refresh and logo brightness adjustment to prevent image retention and reduce the risk of burn-in.

Exquisite Color Accuracy Outstanding Visual Clarity
The S2721BO boasts 99% DCI-P3 color gamut coverage and native 1O-bit color depth, delivering vibrant and smooth color transitions. Paired with 2560×1440 QHD resolution, it offers crisp, lifelike visuals for design work and 3A gaming.

HDR True Black 400 Bright and Dark in Harmony
The S2721BO is HDR True Black 400 certified and features a QD-OLED panel with a high static contrast ratio of 1,500,000:1. This allows it to display deep, pure blacks and intricate details, delivering a vivid and lifelike visual experience.

Powerful Gaming Performance Unleash Your Full Potential
Experience smooth, ultra-responsive gaming with a 360Hz refresh rate, ensuring fluid visuals and faster reactions. The super-fast 0.03ms GTG3 response time reduces motion blur, making game details sharper and improving your aim and movement.

Enhanced Multitask Productivity Intelligent Split Screen
PIP/PBP allows you to manage dual signal sources on one screen for seamless multitasking. It also supports KVM mode, enabling you to control multiple devices with a single keyboard and mouse for greater convenience.

RGB Lighting Effects
KVM Supports Keyboard and Mouse To Control Mobile Devices
1. Connect the USB upstream cable from the PC to activate the monitor's USB ports (skip this step if using a mobile device with single Type-C port).
2. Plug your keyboard and mouse into the monitor's USB ports.
3. Switch between signal sources in the OSD men.

Low Blue Light Hardware Effective Eye Care
The monitor has a low-blue light screen with an anti-glare coating, making it easier on the eyes. It is Tüv Rheinland certified to reduce blue light without affecting color quality, offering better eye protection and a comfortable viewing experience, even in bright settings.
