Detailed Acer KG271U Review

The Acer KG271U gaming monitor has a frameless design with ultra-slim bezels.

  • It also has a matte screen coating that prevents light reflections. Unfortunately, the design can only be tilted, although it is VESA mount compatible.
  • The monitor is adorned with wing-shaped stripes that give the KG271U an expensive look, awe-inspiring for an inexpensive 75Hz monitor.
  • With the slim bezels, distractions are minimal, leaving space to add more monitors that can be configured as a full-fledged command center.
  • You can rotate the monitor +/- 35° and tilt -5°/15°. The metal stand has a thick base and is height adjustable up to 130 mm, something few competing monitors offer at this price.
  • The adjustable stand is convenient, and a hole in the neck allows for better cable management.
  • Also, the Acer KG271U can be wall-mounted with the VESA 100x100mm model.
  • The monitor itself weighs around 10 pounds, making it light enough to take with you if you have to move your setup.

The Acer KG271U is based on a 27-inch TN panel that delivers brilliant image quality with 2560 x 1440 WQHD resolution.

  • The monitor boasts a pixel density of 109 PPI (pixels per inch) and offers you plenty of screen space and razor-sharp details.
  • The device has true 8-Bit color depth, a static contrast ratio of 1000:1, and a vast 122% sRGB color space that enhances the screen colors for a rich and vivid experience.
  • The screen sports a maximum brightness of 350 cd/m². It’s bright enough for your games to fly in well-lit conditions.
  • The above specs are standard for a monitor in this price range, but TN panels have narrow viewing angles of 160 °/170 °, so the hue of the image changes when viewed from oblique angles. However, they also have the fastest response time for fast-paced games.
  • After all, TN panels have the weakest colors compared to other panels, but at least in this price range, that’s the price for such a quick response time.

  • All screen stuttering and tearing disappear within this range with a minimal input lag penalty (~1 ms).
  • Also, you can use the monitor with NVIDIA graphic cards, but not with dynamic refresh rate technology.
