27 inch IIYAMA G-MASTER GCB2784HSU-B1 curved VA gaming monitor 240Hz FHD 1920x1080 USB hub speakers VESA

The IIYAMA G-MASTER GCB2784HSU-B1 is a 27" curved VA gaming monitor with Full HD (1920×1080) resolution designed for fast-paced gaming. Its 1500R curvature and VA panel deliver deeper immersion and strong static contrast, while a 240 Hz refresh rate combined with a 0.7 ms MPRT response time and Adaptive Sync support reduces motion blur and tearing for clearer, high-frame-rate performance. The monitor includes built-in speakers, a USB 2.0 hub and VESA mounting with height adjustment for flexible desktop setups.

Advantages

High refresh rate and very low motion-persistence response provide smooth motion clarity for competitive and fast-action titles. The curved VA panel offers improved perceived depth and a high typical contrast ratio for deeper blacks. Practical connectivity and ergonomics — including an integrated USB hub, speakers and VESA compatibility with height adjustment — make the monitor convenient for gaming and multimedia use.

Suitable for

When it may not be suitable

This monitor uses a 27" Full HD (1920×1080) resolution on a curved VA panel; users who require higher pixel density for detailed photo or video editing, or those who prefer 1440p/4K resolution for productivity, may find the FHD pixel density insufficient. Additionally, the panel prioritizes contrast and motion clarity over the absolute fastest pixel response characteristics of some IPS gaming panels.

How to use

Connect the monitor to your PC or console using a compatible high-refresh-rate-capable video cable and enable the 240 Hz refresh rate in your system or graphics driver settings. Turn on Adaptive Sync (FreeSync) in both the monitor OSD and the GPU driver when supported to reduce screen tearing. Use the built-in USB hub for peripherals and the integrated speakers for basic audio; for more advanced audio, connect external speakers or headphones. Adjust height via the stand or mount the monitor using the VESA interface to achieve an ergonomic viewing position.

What to consider before purchase

Recommendations

For the best experience in competitive gaming, pair this 240 Hz curved VA monitor with a PC or console capable of consistently high frame rates. Enable Adaptive Sync and set the refresh rate in your graphics settings, and use a high-quality video cable to ensure stable 240 Hz output.
