iiyama G-MASTER GC2784HSU-B1 27" Curved 240Hz Gaming Monitor
The iiyama G-MASTER GC2784HSU-B1 is a 27-inch curved gaming monitor built for competitive players who need fast, fluid visuals without motion blur. Its 240Hz refresh rate and 0.7ms MPRT response time are paired with a 1500R curved VA panel to keep you locked into the action, while AMD FreeSync Premium keeps tearing and stuttering in check across a wide range of framerates.
Why this product
240Hz refresh rate with 0.7ms MPRT
At 240 frames per second and a 0.7ms MPRT response time, fast-moving scenes stay sharp and readable, giving you a clear view of opponents even during rapid camera movements.
1500R curved VA panel
The 1500R curvature wraps the display around your field of view for a more immersive experience, while the VA panel technology delivers a 4000:1 static contrast ratio for deep blacks and visible shadow detail.
AMD FreeSync Premium adaptive sync
FreeSync Premium enforces low framerate compensation and low input latency, eliminating screen tearing and stuttering even when your GPU's output varies.
Black Tuner for shadow visibility
The Black Tuner lets you independently lift dark areas of the image, making it easier to spot enemies hiding in shadowed environments without blowing out bright areas.
HDR10 and 99% sRGB coverage
HDR10 support and 99% sRGB coverage (typical) mean colours are reproduced accurately and with enhanced dynamic range across both SDR and HDR content.
USB hub, dual HDMI 2.1 and DisplayPort 1.4
Two HDMI 2.1 ports, a DisplayPort 1.4 output, and a two-port USB 2.0 hub reduce cable clutter and make it straightforward to connect multiple sources and peripherals.

- AC input voltage of 100–240 V makes it suitable for use in multiple regions without a separate power converter.
- Tilt adjustment is included, but there is no height adjustment on the stand — consider a VESA arm if ergonomic height positioning is needed.
- FreeSync Premium adaptive sync is not certified for NVIDIA G-Sync; compatibility with NVIDIA GPUs depends on driver support and is not guaranteed by the manufacturer.
Best for
- Competitive multiplayer gamers who prioritise motion clarity — the 240Hz refresh rate and 0.7ms MPRT are specifically aimed at fast-paced titles where reaction time matters.
- Players on AMD-based systems who want to make full use of FreeSync Premium to eliminate tearing and maintain smooth frame delivery.
- Users who want immersive single-screen gaming without a multi-monitor setup — the 1500R curvature provides a wraparound feel on a single 27-inch display.
- Desktop setups with limited space — at 4 kg with stand and 192.5 mm depth, it has a relatively compact footprint for a 27-inch curved panel.
- Buyers who want built-in audio and USB connectivity — the 2 x 2W speakers, headphone output, and USB 2.0 hub reduce the need for additional peripherals at the desk.
Trade-offs
- Content creators or designers requiring wide colour gamut beyond sRGB — no DCI-P3 or Adobe RGB coverage figure is stated for this display.
- Users needing ergonomic height adjustment — the stand does not offer height adjustment, which can limit comfortable positioning for some users.
- Those wanting high-resolution output — the panel is Full HD (1920 x 1080), so at 27 inches pixel density is lower than QHD or 4K alternatives at the same screen size.
- Buyers seeking premium audio — the built-in speakers are rated at 2 x 2W, which is modest for media consumption or immersive single-player audio.
- NVIDIA GPU users expecting guaranteed variable refresh — the display carries AMD FreeSync Premium certification; G-Sync compatibility is not stated by the manufacturer.
