IIYAMA G-MASTER - 34" UltraWide QHD 200Hz Curved Gaming Monitor - GCB3484WQSU-B2 - VA, FreeSync Premium, HDR400

34 inches of curved UltraWide immersion, engineered for competitive performance

The IIyama G-MASTER GCB3484WQSU-B2 is a 34 inch UltraWide QHD curved gaming monitor built for sim racers and competitive gamers who want a single-screen solution that delivers genuine peripheral coverage without the complexity of a triple monitor setup. A VA panel at 3440 x 1440 resolution with a 1500R curve running at 200Hz gives you the contrast depth, screen width, and refresh speed that demanding applications require.

With a 0.6ms MPRT response time and FreeSync Premium support, the GCB3484WQSU-B2 keeps motion sharp and tear-free across the full refresh range. The 21:9 aspect ratio creates a natural wraparound field of view that reduces the head movement required to track corners, mirrors, and surrounding traffic without the bezel gaps of a multi-monitor configuration.

For sim racers who want the immersion of a wide field of view in a single, clean display, the GCB3484WQSU-B2 is one of the strongest options at this screen size. Pair it with a SIMGASM freestanding or integrated monitor stand for a stable and perfectly positioned ultrawide solution.

A curved VA panel that changes how the track looks

The 1500R curvature of the GCB3484WQSU-B2 follows the natural shape of human peripheral vision, placing every part of the 34 inch display at a consistent viewing distance from the driver's eyes. In sim racing, this means the edges of the screen feel as immediate and as sharp as the centre, without the distortion or fisheye effect that uncurved ultrawide panels can introduce at large sizes.

The VA panel technology delivers a native contrast ratio of 4000:1, which is significantly higher than IPS alternatives at this screen size. In sim racing environments, deeper contrast means more convincing dark cockpit interiors, more readable shadow detail in tunnels and low-light sections, and more visible distance in night racing scenarios.

The 1.07 billion colour depth and 99% sRGB coverage ensure that both the racing environment and the surrounding sim software are rendered accurately and vividly across the full gamut.

200Hz refresh rate with FreeSync Premium

At 200Hz maximum refresh rate, the GCB3484WQSU-B2 keeps motion coherent across every sim racing scenario. High-speed straights, fast direction changes, and close-quarter racing all resolve with the kind of smoothness that lower refresh rate panels cannot provide.

FreeSync Premium certification goes beyond the standard FreeSync specification, requiring a minimum 120Hz refresh rate within the supported variable refresh range and adding Low Framerate Compensation to prevent stutter when frame rates drop below the minimum sync threshold. For sim racing sessions where GPU load varies across tracks and weather conditions, this additional level of adaptive sync reliability is a practical performance advantage.

Flicker-free technology and Low Blue Light certification work together to reduce eye fatigue during extended sessions. For drivers spending multiple hours on the rig across a race weekend or endurance session, these features contribute meaningfully to sustained focus and comfort.

HDR400 for enhanced dynamic range

The GCB3484WQSU-B2 carries HDR400 certification, with a peak brightness of 450 cd/m squared in SDR mode. High Dynamic Range 400 content expands the visible tonal range beyond standard dynamic range, adding detail and depth to highlights and shadow areas in compatible titles.

The VA panel's high native contrast ratio works particularly well in combination with HDR content, delivering a more convincing HDR presentation than panels with lower native contrast are able to provide. In sim racing environments with varied lighting, including sunrise and sunset conditions, wet weather, and overcast circuits, the additional tonal range makes a visible difference to the quality of the rendering.

UltraWide ergonomics for a proper driving position

The stand of the GCB3484WQSU-B2 offers 15cm of height adjustment, full tilt adjustment, and pivot capability, providing the range needed to position a 34 inch curved display correctly relative to a fixed sim racing cockpit. Getting the centre of the screen at the correct eye level is essential for natural peripheral coverage in an ultrawide configuration, and the stand adjustment range covers the geometry required across most cockpit and seating configurations.

The VESA 100 x 100mm mounting pattern makes the GCB3484WQSU-B2 compatible with the full range of SIMGASM monitor stand solutions. For drivers who want to remove the stand entirely and mount the display on a dedicated monitor arm or cockpit-integrated stand, the VESA interface makes that transition straightforward.

Connectivity for a complete sim racing workstation

The GCB3484WQSU-B2 includes two HDMI ports, one DisplayPort 1.4 input, a USB 3.2 Gen 1 hub with four downstream Type-A ports, a 3.5mm headphone output, and a built-in 2 x 5W speaker system. HDCP support ensures compatibility with protected content across all connected sources.

The integrated USB hub provides additional connectivity for SimHub controllers, handbrake units, button boxes, and other sim racing peripherals without requiring a separate hub. The included cable set covers power, USB, HDMI, and DisplayPort connections at 1.85m lengths, providing enough reach for most cockpit configurations.

The Kensington lock slot adds a physical security option for studio and shared environments.
