My Secondary Monitor
Depending if your able to purchase this monitor, It was the last one at my location at $139.99 black friday 2025 price. The KGB271U maybe discontinued or a model upgrade is in the future. It is a Great Gaming monitor at this price, Display port at max 200hz or using hdmi at 144hz (PS5 and XBOX Series X @ 120hz max, make sure using better 4k/8k hdmi cable). The Only downside on this purchase was monitor did not have a hdmi cable only had display port cable and power cable, so If your able to snag up this monitor make sure you purchase a 2.1 hdmi cable on the side. As a beginner in the gaming pc level I'd say finding this monitor at this price was a nice deal for 1440p.

Fantastic 27” 1440p 200Hz monitor
I recently got the Acer Nitro KGB271U and it’s been awesome. The 27‑inch 1440p screen looks sharp and vibrant, and the 200 Hz refresh rate makes gameplay incredibly smooth. This monitor is also perfect for my dual‑monitor setup when I’m day trading — I can see multiple charts and windows clearly without feeling cramped. Colors are great, motion is buttery, and input lag is super low. Whether for gaming or work, it delivers excellent performance and value. Highly recommend it!
