iiyama G-Master GB2745QSU-B1 Black Hawk 27"

Manufacturer: iiyama

The iiyama G-Master GB2745QSU-B1 Black Hawk is a 27-inch gaming monitor built around an IPS, LED-backlit panel with a matte surface finish. It carries a 2560 x 1440 resolution at 108 ppi, and the stand supports both tilt and swivel adjustments as well as VESA mounting, giving users a reasonable degree of setup flexibility. Built-in stereo speakers rated at 2 x 2W are included, and a 3.5 mm audio jack is available for headset use.

On the performance side, the display runs at 100Hz with a 1 ms response time and supports AMD FreeSync adaptive synchronization for smoother rendering during variable frame rate content. Connectivity covers one HDMI 2.0 port, one DisplayPort 1.2 output, and two USB 3.1 ports. The panel delivers wide 178-degree viewing angles both horizontally and vertically, a contrast ratio of 1300:1, and a typical brightness of 250 nits, while operating power consumption sits at 21W with a 0.3W standby draw.

Pros
  • AMD FreeSync adaptive synchronization helps reduce screen tearing during variable frame rate gaming sessions
  • A 1 ms response time keeps motion blur minimal during fast-paced content
  • The matte panel surface reduces reflections in lit environments without a separate anti-glare coating
  • Built-in stereo speakers rated at 2 x 2W provide basic audio output without requiring external hardware
  • The stand supports both tilt and swivel adjustments, and VESA mounting is available for alternative setups
  • USB 3.1 ports allow for faster data transfer when connecting peripherals through the monitor
Cons
  • The height adjustment range is only 1.5 cm, offering very limited vertical positioning flexibility
  • Portrait mode is not supported, restricting layout options for users who prefer a rotated orientation
  • Color calibration is not available, making the display unsuitable for workflows that require verified color accuracy
  • Typical brightness of 250 nits may be insufficient in well-lit or bright ambient environments
  • Only two USB ports are available, which may not be enough for users with multiple peripherals
  • No USB Type-C connectivity, limiting compatibility with modern laptops and devices that rely on that interface
Who is this for?

The iiyama G-Master GB2745QSU-B1 Black Hawk is well-matched for casual and mid-level gamers who benefit from AMD FreeSync and a 100Hz refresh rate to reduce tearing during everyday gaming sessions. The 1 ms response time keeps fast motion reasonably clean, and the matte panel surface suits users working in moderately lit rooms where reflections would otherwise be distracting. Those who prefer a tidy desk setup with minimal external hardware will also appreciate the built-in stereo speakers and the range of wired input options, including HDMI 2.0 and DisplayPort 1.2.

Who is this NOT for?

Users with strict color accuracy requirements — such as photo editors, graphic designers, or video colorists — will find this monitor unsuitable, as it lacks color calibration support and is not positioned for professional color work. The height adjustment range of only 1.5 cm makes it a poor fit for users who need meaningful ergonomic flexibility, and the absence of portrait mode rules it out for those who prefer a vertically oriented workspace. Additionally, users who depend on USB Type-C connectivity or need more than two USB ports for peripheral management may find the connectivity options too limited for their workflow.
