True Tandem RGB OLED Technology

The PG27UCWM introduces a true RGB Stripe sub-pixel arrangement designed to improve visual clarity and color performance compared with traditional WOLED layouts.

By removing the white subpixel used in conventional WOLED panels, Tandem RGB OLED technology delivers up to 27% larger color volume, particularly at high luminance levels.

The RGB Stripe layout also improves text clarity, making the display suitable not only for gaming but also for desktop use, browsing, productivity, and content creation.

Dual Mode: 4K 240Hz or FHD 480Hz

One monitor can now cover both cinematic AAA gaming and ultra-competitive esports. A dedicated Dual Mode function allows you to switch between 3840×2160 4K resolution at 240Hz and Full HD at up to 480Hz.

Use 4K 240Hz when visual quality, detail, and immersion matter most, then switch to 480Hz for competitive FPS titles where motion clarity and responsiveness take priority.

Combined with the OLED panel's 0.03ms GTG response time, the PG27UCWM is built for extremely smooth motion and low-latency gameplay.

TrueBlack Glossy OLED Panel

ROG's exclusive TrueBlack Glossy optical layer is designed to preserve deep OLED blacks while maintaining a clean glossy presentation.

An advanced anti-reflective layer reduces ambient reflections by up to 38% compared with previous-generation glossy WOLED panels, helping maintain image clarity in brighter gaming rooms.

The result is exceptional contrast, vibrant colors, and deep blacks without sacrificing the sharp appearance expected from a premium glossy OLED display.

HDR and Professional Color

The PG27UCWM covers 99% of the DCI-P3 color gamut with factory color accuracy of Delta E < 2 and true 10-bit color reproduction.

It supports HDR10 and Dolby Vision and carries VESA DisplayHDR 400 True Black certification, with HDR peak brightness rated up to 1000 cd/m².

1,500,000:1 OLED Contrast

Self-emissive OLED pixels produce an extremely high 1,500,000:1 typical contrast ratio for true blacks, bright highlights, and strong image depth.

The combination of OLED contrast, wide color gamut, and ultra-fast pixel response makes the monitor suitable for both immersive single-player games and fast competitive titles.

OLED Care Pro with Neo Proximity Sensor

ASUS OLED Care Pro includes multiple technologies designed to protect the OLED panel during long-term use.

The Neo Proximity Sensor detects when the user moves away from the monitor and can automatically transition the screen to black to help protect against panel burn-in. The image returns when the user comes back.

Additional OLED protection features include Pixel Cleaning, Screen Move, Screen Saver, Logo Brightness Adjustment, Outer Dimming Control, Target Mode, adjustable Motion Sensitivity, and Auto Away Timer.

Custom Heatsink and GaNFET Cooling

The PG27UCWM uses a custom heatsink and optimized internal airflow system to manage OLED panel temperatures and support long-term panel durability.

Advanced GaNFET power technology improves power efficiency while reducing waste heat, allowing the internal power design to remain compact and efficient.

ASUS states that this design produces nearly 35% less waste heat and approximately 10% cooler vent temperatures compared with the previous power solution.

G-SYNC and FreeSync Premium Pro

NVIDIA G-SYNC compatibility and AMD FreeSync Premium Pro help deliver smooth variable-refresh-rate gaming with reduced tearing and stutter.

OLED Anti-Flicker and ELMB

ROG OLED Anti-Flicker technology is designed to reduce visible flicker caused by frame-rate fluctuations, while ASUS Extreme Low Motion Blur helps reduce ghosting and motion blur.
