27-inch WQHD VA gaming monitor

The CUNPU GN05AC is a 27-inch gaming monitor built on a VA panel with a 2560 x 1440 resolution. It targets players who want high refresh rates and strong contrast in a frameless design. The 16:9 aspect ratio and 178-degree viewing angles suit both competitive and immersive titles.

240 Hz refresh rate with 1 ms response

The single specification that decides fit is the 240 Hz maximum refresh rate paired with a 1 ms grey-to-grey response time. Adaptive Sync (FreeSync) keeps frame delivery smooth across 240 Hz, 200 Hz, 165 Hz, 144 Hz, 120 Hz and 100 Hz modes. Buyers whose graphics card cannot sustain frame rates above 144 Hz at 1440p will not use the panel’s full capability.

Sustained 300 cd/m² brightness and 3000:1 DCR

Under continuous load the monitor maintains 300 cd/m² typical brightness and a 3000:1 dynamic contrast ratio. The VA panel covers 99 percent sRGB and 90 percent DCI-P3 without colour shift during long sessions. No local-dimming or HDR peak-brightness figures are provided, so extended HDR content relies on the static contrast performance alone.

Questions about this item

How does the 240 Hz refresh rate translate to actual gameplay smoothness?

The panel refreshes 240 times per second and supports compatible lower rates such as 200 Hz, 165 Hz, 144 Hz, 120 Hz and 100 Hz, so fast motion in FPS or RTS titles stays fluid without tearing when paired with a GPU that can drive those frame rates.

What adaptive-sync standard does the monitor use and what refresh range does it cover?

It uses AMD FreeSync adaptive sync, which works across the panel's full variable refresh range up to the native 240 Hz ceiling to eliminate stutter and tearing when the graphics card output fluctuates.

What VESA mount pattern and stand adjustments are available for installation?

The monitor is VESA compatible for wall or arm mounting and the included stand provides tilt adjustment; the cabinet features a three-sided frameless bezel for minimal gaps in multi-monitor layouts.
