iiyama G-Master GB2745HSU-B1 Black Hawk 27"

Manufacturer: iiyama

The iiyama G-Master GB2745HSU-B1 Black Hawk is a 27-inch gaming monitor built around an IPS panel with LED backlighting and a matte finish. It targets users looking for a straightforward gaming display with adaptive sync support, offering AMD FreeSync alongside a 1 ms response time to help reduce motion blur during fast-paced gameplay. The stand supports tilt, swivel, and height adjustment, and the monitor is also VESA mount compatible for those who prefer a third-party arm.

The panel delivers a resolution of 1920 x 1080 px at 81 ppi with a 100 Hz refresh rate, a typical brightness of 250 nits, a contrast ratio of 1000:1, and a color output of 16.7 million colors across 178-degree viewing angles both horizontally and vertically. Connectivity includes one HDMI 1.4 port, one DisplayPort 1.2 output, two USB 2.0 ports, and a 3.5 mm audio jack, while USB Type-C, Ethernet, Wi-Fi, and DVI are absent. The monitor also features built-in stereo speakers rated at 2 x 2W and operates at 22W during use, dropping to 0.5W in standby.

Pros
  • AMD FreeSync adaptive sync support helps reduce screen tearing during gameplay without requiring a specific GPU vendor
  • The IPS panel delivers 178-degree viewing angles both horizontally and vertically, keeping colors consistent from off-center positions
  • A matte panel surface reduces reflections in lit environments without relying on a separate anti-glare coating
  • The stand supports both tilt and swivel adjustments and is VESA mount compatible, giving users several options for physical setup
  • Built-in stereo speakers rated at 2 x 2W and a 3.5 mm audio jack provide basic audio flexibility without needing external hardware
  • Standby power consumption of just 0.5W keeps idle energy draw minimal
Cons
  • The height adjustment range is only 1.5 cm, which severely limits ergonomic positioning for most users
  • Portrait mode is not supported, ruling out vertical orientation for users who work with long-form documents or code
  • HDMI connectivity is limited to version 1.4, which caps bandwidth for higher refresh rate or resolution scenarios
  • Only two USB 2.0 ports are available, with no USB Type-C, making peripheral hub functionality quite limited
  • Color calibration is not supported, which reduces its suitability for color-sensitive work
  • Typical brightness of 250 nits may be insufficient in bright room conditions
Who is this for?

The iiyama G-Master GB2745HSU-B1 Black Hawk is well suited to casual and entry-level gamers who want a dedicated gaming monitor with AMD FreeSync and a 1 ms response time to keep gameplay smooth and responsive. The wide 178-degree viewing angles and matte panel surface also make it a reasonable fit for general desktop use in moderately lit environments, where glare management matters but brightness demands are not high. Users who value physical setup flexibility will appreciate the tilt, swivel, and VESA mount support, which offers a reasonable range of positioning options beyond the limited height adjustment.

Who is this NOT for?

This monitor is not well suited to users with professional color work requirements, as it lacks color calibration support and its 250-nit brightness limits visibility in brighter working conditions. Those who need a versatile multi-device hub will find the connectivity restrictive, given the absence of USB Type-C and the limitation of HDMI 1.4 and only two USB 2.0 ports. Users who frequently rotate their display or require significant height adjustability for ergonomic desk setups will also be underserved, since portrait mode is unsupported and the height adjustment range is just 1.5 cm.
