With a 4K monitor, text and images appear sharp and clear compared with lower resolutions. You can see the difference between the text and your smartphone’s HD display, just like when you look at your smartphone’s screen. The image is sharper and has better image quality in gaming. A 1080p or 1440p monitor is nothing like this. A 4K resolution has 3x more pixels than a 1440p or a 1080p resolution. If you want to drive pixels and push frames, you need a potent graphics card. Even though many modern graphics cards can handle 4K resolution, playing games at 4K is very different.
