5. Key Features
5.1 WQHD IPS Panel with High Refresh Rate
The 27-inch WQHD (2560x1440) IPS panel provides a larger viewing area and sharper images compared to Full HD, with excellent color reproduction and wide viewing angles. The 155Hz (overclockable to 165Hz) refresh rate ensures smooth motion and reduced input lag, crucial for fast-paced gaming. A 1ms Moving Picture Response Time (MPRT) further minimizes motion blur.

5.2 ELMB Sync (Extreme Low Motion Blur Sync)
ELMB Sync technology enables the simultaneous activation of Extreme Low Motion Blur (ELMB) and Adaptive-Sync (G-SYNC Compatible). This feature reduces ghosting and motion blur, providing clearer visuals in fast-moving scenes without the tearing artifacts typically associated with fixed refresh rates.

5.3 G-SYNC Compatible / Adaptive-Sync
The monitor is certified as G-SYNC Compatible, ensuring a smooth, tear-free gaming experience by synchronizing the monitor's refresh rate with your GPU's frame rate. This eliminates screen tearing and minimizes stuttering, especially during variable frame rate scenarios.
5.4 HDR10 Support
The VG27AQ supports the industry-standard HDR10 format, offering enhanced color and brightness levels compared to standard monitors. This results in more vibrant colors and better contrast in compatible content.
