General Work Usage

The iiyama G-Master GB3290QSU-B1 delivers a modest 66.1% productivity score, making it suitable for casual or part-time work tasks like email, browsing, or occasional document editing. It utilizes an IPS panel—a top-tier choice for productivity. IPS and similar panels deliver exceptional color accuracy, wide viewing angles, and consistent brightness across the screen. Their resistance to burn-in makes them especially well-suited for prolonged use involving static content like spreadsheets, toolbars, and text editors. The monitor’s high resolution of 2560×1440 delivers sufficient screen space for most productivity tasks, though less than ultra-wide or 4K displays. A lower pixel density of 93 ppi can lead to visible pixelation, reducing visual comfort for reading and detailed work, especially on larger screens. With a typical brightness of 400 nits, this monitor maintains excellent visibility even in well-lit office spaces.

The iiyama G-Master GB3290QSU-B1 has color space coverage of: 96.00% sRGB , 72.00% NTSC, which gives this monitor limited color gamut coverage, which makes it unsuitable for color-accurate work such as professional design, printing, or video editing. The screen may fail to represent colors consistently across devices or in print. The 8-bit panel combined with restricted gamut coverage makes this monitor appropriate only for non-color-sensitive tasks like document editing or web browsing.

The work performance-per-price score of 16.5% indicates that this monitor does not offer strong value for professional productivity use. Given both the modest work suitability score and weak value proposition, there are likely better alternatives in the same price class.

Gaming and Media Usage

The iiyama G-Master GB3290QSU-B1 earns a solid 75.8% rating for gaming and media use, offering smooth visuals, decent color accuracy, and responsive performance that will satisfy most gamers and movie enthusiasts. It utilizes an IPS panel, which is widely appreciated for accurate color reproduction, wide viewing angles, and consistent brightness. These panels are a balanced and reliable choice for gamers who enjoy vivid visuals and moderate HDR. High-end IPS models often support local dimming zones and high peak brightness levels, enhancing the experience in HDR games and bright rooms. While response times are slightly slower than OLED or TN, recent advancements have greatly reduced motion blur and input lag. The monitor’s high resolution of 2560×1440 strikes a good balance between image sharpness and system performance, making it suitable for most gaming scenarios without overly taxing the GPU. The monitor features an ultra-high refresh rate of 240 Hz, ideal for competitive gaming, fast-paced shooters, and high-FPS esports titles, but the slow response time may introduce noticeable ghosting or motion blur in competitive scenarios.

The monitor provides very good ergonomic support, enabling users to adjust it for improved comfort during extended gaming, viewing, or daily activities, and provides very good connectivity, meeting the needs of most users in typical home or multi-purpose environments.
