27 inch iiyama G-MASTER GC2784HSU-B1 curved VA monitor 240 Hz Full HD 1920x1080 USB hub speakers VESA

The iiyama G-MASTER GC2784HSU-B1 is a 27" curved VA gaming monitor with Full HD (1920 x 1080) resolution, a 240 Hz refresh rate and a 0.7 ms MPRT response time. Its 1500R curved panel and high native contrast ratio are designed to deliver deep blacks and clear motion for fast-paced gaming. The monitor includes built-in speakers, a USB 2.0 hub and VESA mounting support for flexible setup.

Advantages

This monitor combines a high 240 Hz refresh rate with a rapid 0.7 ms MPRT response time to minimise motion blur and input lag, making fast on-screen movement appear smoother and easier to track. The VA panel offers strong static contrast for deeper blacks and better perceived depth compared with typical IPS displays. Adaptive Sync support helps eliminate tearing and stutter when paired with compatible GPUs, while built-in speakers and a USB hub add convenience for a compact desktop setup.

Suitable for

When it may not be suitable

The 1920 x 1080 Full HD resolution on a 27" screen results in a lower pixel density than higher-resolution monitors, so text and fine detail are less sharp compared with QHD or 4K displays. Photographers, designers and users who require the highest colour accuracy or very fine image detail may find higher-resolution or colour-accurate IPS panels more appropriate.

Key specifications

How to use

Connect the monitor to your PC or console using a supported video cable and enable a 240 Hz refresh rate in the operating system or graphics driver settings. Activate Adaptive Sync/FreeSync in both the monitor OSD and GPU driver if supported to reduce screen tearing. Use the built-in USB hub for peripherals and the integrated speakers for basic audio; for critical audio, use external speakers or headphones. Mount the display on a VESA arm or stand if preferred, following the included instructions for safe installation.

What to consider before purchase

Recommendations

For the best gaming experience, pair the iiyama G-MASTER GC2784HSU-B1 with a GPU capable of high frame rates, enable 240 Hz in settings, and turn on Adaptive Sync. Use the curved VA panel at typical viewing distance to benefit from improved immersion and deeper black levels.
