Large IPS gaming with QHD at 240 Hz
31.5-inch IPSQHD 240 HzFreeSync Premium150 mm height
The G-Master Gold Phoenix GB3290QSU-B1 combines a flat 31.5-inch IPS panel with QHD resolution and up to 240 Hz through HDMI or DisplayPort. FreeSync Premium, an adjustable-height stand, a four-port USB hub and 2×4.5 W speakers support a substantial gaming desk.
Best For: PC gamers seeking a large flat IPS QHD display, high refresh and adjustable screen height.
Before you order: QHD 240 Hz requires a compatible source, cable and settings. The console output determines available modes; no console 240 Hz promise is made. USB-C sockets are downstream data ports, not laptop video/PD docking. The manufacturer specifies height, tilt and swivel without stand pivot.
What's in the Box
- Monitor with stand and power cable.
- USB cable 1.5 m, HDMI cable 1.5 m, DisplayPort cable 1.8 m, quick start and safety guides.
- Computer, peripherals and optional VESA arm are separate.
What It Means in Practice
- Connect HDMI 2.1 or DP 1.4 for supported QHD modes up to 240 Hz.
- Enable supported FreeSync Premium with a compatible GPU and settings.
- Connect USB-B upstream to activate two USB-A and two USB-C downstream ports.
- Adjust height by 150 mm, swivel ±45° and tilt +23°/−5°; allow for the 290 mm stand depth.
What Will Not Work
- Game frame rates and console modes depend on the source; the panel refresh rating is not an FPS guarantee.
- 1 ms is MPRT, not GTG. Motion-blur reduction and adaptive-sync settings have different operating conditions.
- No USB-C laptop video/PD dock, webcam, touch or stand pivot is specified.
- HDR Ready does not imply advanced local dimming or reference HDR performance.
