27-inch QHD Fast IPS gaming with up to 320Hz refresh

2560 × 1440Fast IPSUp to 320Hz150mm height adjustment

The iiyama G-MASTER GB2791QSU-B1 Gold Phoenix combines a 27-inch QHD Fast IPS panel with refresh rates up to 320Hz and a specified 0.6ms MPRT response time. Its adjustable stand, USB hub and integrated speakers make it a practical desktop gaming display, while DisplayPort and two HDMI inputs give you several ways to connect your equipment.

Best For: PC gamers who want QHD detail and high refresh rates with an adjustable stand, and who have a graphics card capable of their target resolution and frame rate.
Before you order: For QHD 320Hz with adaptive sync, use a compatible DisplayPort setup. HDMI reaches QHD 320Hz without adaptive sync; its listed adaptive-sync range stops at 300Hz. USB-C ports are downstream USB hub ports, not video inputs or laptop charging docks. The 0.6ms figure is MPRT, not a stated grey-to-grey time.

What's in the Box

  • iiyama G-MASTER GB2791QSU-B1 monitor with adjustable stand
  • Power, USB, HDMI and DisplayPort cables, each listed at 1.8m
  • Quick start guide and safety guide

What It Means in Practice

  • Choose the refresh rate in your operating system and game settings. A 320Hz panel does not make every game run at 320 frames per second.
  • Connect the USB Type-B upstream port to the computer to use the downstream hub: two USB-A and two USB-C ports.
  • Adjust height through 150mm, swivel, tilt or pivot to suit your desk. A compatible 100 × 100mm VESA mount can replace the stand.
  • Use the built-in 2 × 2W speakers for basic audio or the headphone output for headphones.

What Will Not Work

  • The USB-C ports do not replace an HDMI or DisplayPort video cable, and their 5W rating does not provide laptop-class charging.
  • HDR10 support alone is not a promise of local dimming or a DisplayHDR certification.
  • High refresh, adaptive sync and motion-blur settings depend on the input and selected mode. Check the manual when combining them.

Is 0.6ms the grey-to-grey response time?

Are speakers and cables included?
The monitor has 2 × 2W speakers. Power, USB, HDMI and DisplayPort cables are listed as included.
Singular Expert Insight

Match the connection to the mode you actually intend to use. DisplayPort is the clearest route to the listed QHD 320Hz adaptive-sync range, while the USB hub needs its own upstream connection. Check graphics performance at QHD before treating the panel's maximum refresh rate as your expected game frame rate.

Buyer’s Guide

✓ Buy it if You want a 27-inch QHD high-refresh gaming display with an adjustable stand and practical USB hub.
✕ Skip it if You need a single USB-C cable for video and laptop charging, or require a 4K native panel.
→ Also consider A suitable DisplayPort output on your GPU and an optional VESA arm if the supplied stand does not suit your desk.
