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.
