Curved Full HD gaming with strong VA contrast
27-inch curved VA1500R / Full HD144 Hz / FreeSyncUSB 2.0 hub
The G-Master Black Hawk GC2781HSU-B1 is a 27-inch 1500R curved VA monitor with Full HD resolution and up to 144 Hz refresh. A 4000:1 static contrast ratio, FreeSync support, HDMI and DisplayPort inputs, stereo speakers and a two-port USB hub make a practical gaming desktop.
Best For: PC gaming and everyday use where a curved screen and VA contrast matter more than higher resolution or an adjustable-height stand.
Before you order: This exact model uses VA, not IPS. A suitable source, cable and settings are needed for 144 Hz and FreeSync. The supplied stand adjusts tilt only. Connect USB-B upstream to use the USB 2.0 hub. The exact base-model EPREL label is 2584027, distinct from the later A revision.
What's in the Box
- GC2781HSU-B1 monitor and tilt stand.
- Power cable 1.85 m, USB cable 1.5 m, HDMI cable 1.85 m, quick start and safety guides.
- Computer, DisplayPort cable, headphones and optional VESA arm are separate.
What It Means in Practice
- Use HDMI 1.4 or DisplayPort 1.2 from a compatible graphics output and select Full HD up to 144 Hz.
- Enable supported FreeSync with a compatible GPU; the stated operating range is 48–144 Hz.
- Connect the USB-B upstream cable to enable two downstream USB-A ports for peripherals.
- Tilt the screen within +20°/−3° or use a compatible optional VESA 100×100 arm.
- Use 2×2 W stereo speakers or connect headphones.
What Will Not Work
- 144 Hz does not guarantee 144 fps from the game or connected system.
- The stated 1 ms is MPRT, not GTG; motion settings affect the result.
- No height, pivot or swivel adjustment, USB-C laptop dock, webcam or touch is specified.
- Full HD on 27 inches has lower pixel density than QHD or UHD. A curved VA screen is not a flat IPS panel.

Singular Expert Insight
Choose this model for its curve, contrast and Full HD 144 Hz balance. Check desk height because the stand only tilts, and check viewing distance because 27-inch Full HD has larger pixels than QHD. Use the exact manufacturer specification when retailer listings mix IPS and VA terminology.
