This is a piss cheap monitor, with high resolution and good colors. I don't know why they have marketed it to gamer's. Gaming is not the strong side of this monitor, but it does okay. It's better than tv screens for consoles, if that is what they mean with good for gaming. It has a bit bad side view, but not to an extent that you notice it in computer use, it's not really terrible. The stand is horrible thou, I had to find a "smart" solution for that. It has no tilt, so I had to improvise. It has a crass downward angle by default.
Experience from upgrading
Going from 1080p 24" to 2160p 28" was a new world, thats 4 times as many pixels. There are not to much games and video that supports this yet. I wan't another screen to. But I'm saving money for now. A 24" with 144 hz would be fun to try. I am not gaming enough to justify it for now. This screen is very good for video editing and similar. The "gaming" technology makes it easier to use the mouse cursor and see changes faster to. So if you are one of the faster types, this screen will give you some comfort in your workflow. Not as much as getting a full gaming monitor. I can't be dissatisfied with so much for so little, but it's not top notch.
